Lighting

Sidelights/Flashers and Tail Lights – We had previously switched the incandescent bulbs in the flasher/side lights and tail lights in favor of LEDs. These are much brighter, consume lower amperage, and produce less heat. This requires replacing the flasher relay can with a substitute suited for LEDs. In our case, the LED flasher relay is incorporated in the Classic Technologies Fuse Box.

License Plate Lights – the original light fixture used two small incandescent bulbs.We converted these to LEDs sourced from Moss Motors.

Headlights – We ordered new headlights from The Bus Depot. Their web site states: “Essentially generic knockoffs of the old Cibie Z-beams, these are tested and certified to meet stringent E-Code and TUV standards.  This means better light distribution and visibility than the cheapo knockoffs sold on Ebay, etc. (which are not E-code and often don’t even come with protective boots on the back). These are direct bolt-on replacements for your stock 7″ sealed-beam headlights; just pop them in and you’re ready to go. They also have curved glass similar to how the sealed-beams looked, whereas most other E-codes have flatter glass that is more common in Europe. (The difference does not affect performance and is just a matter of personal taste, if you care at all.) They also feature a special anti-fogging coating on the insides of the lenses.”

Cibie Headlights

Then we needed to find some LED lights to put in the headlight bodies. After some research we decided on these units from Classic Car LEDs. These were very reasonably priced for what appears to be high quality units.

Driving Lights – We have considered, but not decided on, installing Lucas driving lights. Since it is a possibility for the future, the wiring harness has incorporated the wiring for the lights should we desire to add them at a later date. This image shows what they look like once installed.

Wiring to the Bonnet

The wiring for the lights in the bonnet is routed through the “J” Deutsch connector that is located in the chassis next to the horns. The individual wires are connected to the bonnet harness using bullet connectors. These are seen in the Bugeye Restoration Video Episode Sixty-six

Headlight Fitting

Before painting the body, we checked to make sure that the headlights and flashers fit correctly. The only change we made from the original was the use of a spring clip at the bottom of the outside chrome trim ring rather then the use of a self-tapping screw. MGs and perhaps later Sprites introduced the spring clip improvement. This makes for a much easier installation and removal of the trim ring which must be done when aligning the headlights for road use. Everything was cleaned, painted or polished and new rubber gaskets and dust excluders were used.

Bugeye Restoration Video Episode Fifty-eight shows the incremental process of installing the headlight assemblies: https://vimeo.com/916270590/1a203247b5?share=copy

The Bugeye Restoration Video Episode Forty (link below) covers our restoration efforts. Where parts were perished, such as rubber seals, they were replaced with new items. However, some original parts were cleaned and repainted to continue their service.

Headlight bowl and mounting ring

Light bulbs in the flashers (turn signals) were replaced with LED units. These are much brighter, consume lower amperage, and produce less heat. This requires replacing the flasher relay can with a substitute suited for LEDs. 

The headlight chrome rims are secured to the headlight bowl with a clip and screw as seen below:

Headlight Trim ring securing screw clip

These screws can be a challenge to mount. MGBs used a spring clip instead of the screw clip. We substituted these spring tension clips and hopefully they will work well. We can always go back to the original approach.

With all of the parts refurbished and accumulated we are now ready for installation at a later date.

Lucas PL700 Headlight Conversion

I have always liked the looks of the Lucas Tri-bar PL700 headlights. Unless one can find some new old stock units on eBay or from an individual seller the originals are hard to locate. However, reproduction vintage lights are available and come with a modern twist in that they utilize H4 bulbs, giving you a vintage headlight look with modern reliability and power. The lights I ordered from NOS Locators come with 12v P43t (9003) H4 bulbs: 60 watt high, 55 watt low. Flosser brand Halogen Bulbs and the bulbs are made in Germany.

This is a link to an article on the technical specifications and general information on the original Lucas PL700s:PL700

Lucas PL700 Reproduction Headlights

Headlamps

To install the new lights the first thing to do is to remove the Phillips head sheet metal screw (2) holding the headlight rim assembly (1). This screw is located to the right of center at the bottom of the ring.

Then remove the rubber dust excluder (4) and the three Phillips head sheet metal screws holding the outside light unit retaining plate (5).

The retaining ring can then be withdrawn providing access to the bulb and it’s electrical connector.

This is a photo of the new headlight with bulb to be installed. A rubber boot to cover the electrical connection was also provided.

Lucas PL700 Headlight and Bulb Rear View

Connecting the new headlight is all “plug and play.” It is just a matter of unplugging the old sealed beam headlight and plugging the three-prong plug into the female plug on the wiring harness.

Then it is simply a matter of holding the PL700 in place while resecuring the light unit retaining plate with the three short Phillips head self tapping screws and replacing the rubber dust excluder. It requires a little finagling but one then slips the tab on the top of the rim assembly over the retaining plate and replacing the Phillips head screw (2) at the bottom of the rim by screwing it into the nut for screw (3). 

Other than a final check of the alignment of the headlamp light beams and adjusting with the spring loaded screws, the job is complete. It is a good look!

Chapter 30 – Cleaning and Trial Fitting

Jeremy Turner’s Work Continues

Headlights and turn signals – Jeremy worked on fitting the headlights and turn signal lights to the front wings/shroud. We discovered that the aluminum wings were not molded properly to fit to the shroud. Some body work is required. The result won’t be perfect, but should only be noticeable to Jeremy, me and someone like Rich Chrysler!

Rear wings and boot lid – Then attention was turned to the back of the car. Rear wings fitted, boot lid tested with the old gasket applied, and the rear rally bumpers fitted as well. Again, great to see continued progress. The goal is to return the car to me in two weeks to be stripped for bodywork, blasting again, and priming of the frame. Getting some red paint on the “Bloody Beast” is nearing!!

Windscreen – Yesterday I took the afternoon off and went to Broadway to help Jeremy with a final check of the exhaust system before drilling the holes in the frame and floorboard for the hangers and to install the windscreen. We did adjust the front mount for the muffler to get it up a little higher. The posts for the windscreen did require some grinding to get the windscreen to fit properly, but after several “trial-and-error” fitting sessions, we got the windscreen installed properly. It really made the shell begin to look like a car! I was so excited with the progress I forgot to take photos. I brought a lot of parts home (emblems, lights and etc.) that fortunately are no longer needed for fitting.

 September 22, 2006

Door shut face finishers again – In order to get the aluminum shut face finishers and the rear quarter panels to fit, we decided that we needed to cut the weld on the front of the hood mount plate and bend it up a bit to have it align with the top of the aluminum trim and to permit the rear quarter panels to slide under. This strategy proved successful, as Jeremy was able to get the new Heritage quarter panels to fit properly. The new shut face finishers from Moss (Kilmartin products) arrived and much to my relief they fit perfectly! The photos also show some small pieces of rubber door seal “Bristle Flex” that came from Macgregor in Canada. It seemed to fit well, although it does not appear as original.

Rear quarte panel fitting 3

The lower bracket that secures the rear quarter panel to the footboard had to be made larger so that it would contain the panel. Jeremy did a nice job of fabricating the brackets. Following complete trial fitting the gap at the front of the hood mount will be welded closed.

Hood Mount Plate – Jeremy welded the front lip of the hood mount plate and completed final fitting of the aluminum door shut finishers along with the vinyl beading. It took some time to get to the point that the door did not rub against the vinyl. 

Anti-sway bar brackets – Then he moved to installing the brackets I purchased from Kilmartin for the anti-sway bar. I still do not understand why Martin Jansen did not install these as part of his Jule frame package.

New Wiring Harness Circuits

Power Inputs to the Classic Technologies’ Relay/Fuse Panel

The Classic Technologies Panel has four primary connections.

Classic Technology's Relay Fuse Panel

Classic Technologies’ Relay Fuse Panel

A – 12V power input from the small fuse box (battery B+) to power the accessories circuits. A brown 12 AWG wire is used to the Yellow screw terminal spade lug connection.

B – 12V power input from the small fuse box (battery B+) to power the high and low beam headlight relays. A brown/blue 14 AWG wire is used to the Blue screw terminal spade lug connection.

C – 12V power input from the small fuse box (battery B+) to power the constant power circuits in the vehicle. A brown 12 AWG wire is used to the Red screw terminal for a spade lug termination.

O – ground or earth to the car’s chassis.

In my case, 12V power is routed from the battery in the trunk to the starter solenoid mounted centrally on the firewall in the engine bay. The negative terminal of the battery is wired to the car’s chassis. A ground strap is used to connect the grounded chassis to the engine/gearbox.

Ground Strap Mounted

Ground Strap Mounted

The battery relocation to the boot was addressed in a previous post.From the solenoid, a brown 8 AWG wire delivers power to a small fuse box with six circuits mounted on the firewall directly below the starter solenoid. I used two nutserts for the mounting to the firewall.  Three of the six fused circuits are then used to provide power to three input terminals on the Classic Technologies’ relay/fuse panel. The additional three are spares for the moment.

The three wires from the small firewall fuse box, the white/red wire from the solenoid to the fuse panel and the heavy 4 AWG cable from the solenoid to the alternator will be “packaged” together in one TechFlex sleeve/cover.

Before getting into the allocation of the thirty-four fuse positions available to use in the Classic Technologies Relay/Fuse panel, it might be helpful to once again point point out that as indicated in the post on new wiring harness connectors I developed a spreadsheet to be used in conjunction with wiring diagrams. The spreadsheet lists all connection points of the electrical wiring system. Links are provided below:

Again, a disclaimer is appropriate: The spreadsheet is provided as guidance for those who might wish to do something similar, but it should not be duplicated or utilized without careful inspection and  approval by a certified automotive electrician.

Circuit Modifications & Additions

Several of the modifications I am making to my MK2 require either modified or new electrical circuits. I highlight below the details of some of these wiring changes.

Starter Solenoid

I replaced the original starter solenoid with a new one sourced from SNG Barratt. The large post closest to the firewall provides the mounting for the 4 AWG cable to the starter. The large post closest to the engine mounts three cables: the 2AWG cable from the battery, the 4AWG cable to the block connector on the electrical panel on the LH engine bay valance (ultimately to the alternator), and a 8AWG wire to the 6-way firewall fuse panel. On the upper small post on the solenoid a single wire from the starter button is attached.

Alternator

I have considerably more power requirements in my car than could be addressed by the original dynamo/generator.

The specifics of the Hitachi 120 amp alternator I am using may be found under the “electrical components” posting. However, I will detail the wiring to support the alternator here.

I decided to go with 4AWG cable and also decided to install a fuse in the line between the alternator and the wiring system to avoid any possibility of a problem with a power surge created by a bad regulator in the alternator.

I sourced the cable and fuse from CE Auto Electric Supply. The folks at CE Auto Electric Supply are very helpful and they sell high quality products. Both products are typically used in high-end sound system applications. This particular cable has 1,862 strands. The cable was terminated with 3/8″ terminals, properly crimped and covered with adhesive shrink tubing.

Alternator Cable CE Supply 4AWG 1862 Strands

Alternator Cable CE Supply 4AWG 1862 Strands

I installed a JL audio premium series master ANL fuse block with a 125 amp “Stinger” ANL style fuse, part number SPF52125 on the lower right portion of the original fuse panel.

ANL 125 Amp Fuse with J&L Holder

ANL 125 Amp Fuse with J&L Holder

Two three-quarter inch long machine screws were used to secure the fuse block to the panel. On one I was able to take advantage of the 10–32 captured nut that was already on the fuse panel, and on the other I used a nutsert with the 10-24 screw.

One of the nice features of this particular fuse block is that the ProStar hexagonal posts can be rotated so that the cable can approach from almost any angle. As you can see in the photo, I took advantage of this feature. After the engine is installed, the alternator cable will be cut to proper length.

As can be seen in the image, the cable from the ANL fuse connects to a connector block also used for the power steering.

Alternator Fuse Mounted

The cable is then routed from the connector block along the LH valance and the firewall to the starter solenoid. It is difficult to track because of all of the in-process wiring, but the path of the alternator cable is visible in the image below:

Alternator Cable Wiring

Alternator Cable Wiring

Power Steering Pump

The installation of the power-assisted rack and pinion steering requires the conversion to negative earth and the installation of an alternator replacing the original dynamo/generator. The kit, as supplied, provided a Lucas 80 amp LMA 604 alternator. However, due to other electrical requirements I chose to upgrade to a 120 amp Hitachi alternator. Details about the alternator are found at this link: https://valvechatter.com/?p=4113.

M&C Wilkinson provided wiring instructions, but my configuration is slightly different than in the application they referenced. The wiring diagram below is my interpretation of the wiring required for the pump in my car.

Five wires emanate from the pump. The heavy brown wire connects to ground. The heavy red cable connects to the supplied 80 amp fuse. The 22 gauge black wire connects to the fuse panel at location #19 or #23. The 22 gauge blue/slate wire connects to the alternator at the indicator lamp post.

Heater Fan Wiring

A full description of the restoration and modification of the heater box and fan may be found at the Heater Post on this Valvechatter website. The following information addresses the wiring of the heater fan.

The orange wire from the motor is connected to ground. The black wire to the “inside” post (closest to the heater box) of the resistor. The slate wire from terminal #6 on the switch is connected to the “outside” post (closest to the blower fan) of the resistor. The white/green wire from terminal #8 on the switch connects to the “inside” post on the resistor. The green/yellow wire from the #4 terminal of the switch is connected to the fuse position #11 for power. With this wiring in place, the lower position of the switch is “off,” the middle position is “Low Speed” and the upper position is “High Speed.”

I created a pigtail (seen below) from the resistor for the heater fan wiring. Two wires in the pigtail are connected through two-way snap connectors to wires of the same color which route through the firewall and ultimately back to the Fan Switch. The black wire in the pigtail goes directly to the fan motor. The orange wire from the motor is the ground and it is connected to the LH valance grounding terminal strip.

Wiper Motor Wiring

As documented in my post entitled Wiper System Upgrade, I installed a Lucas 29W wiper motor kit from Classic Motor Cars in the UK. The upgrade includes a relay mounted behind the central instrument panel assembly. The wiring for the wiper switch is referenced above under the section “Instrument Panel Assembly Switch Wiring.” This is a diagram of the wiring:

A full description of the installation of the Rostra Cruise Control System in my MK2 is provided in the MK2 Cruise Control Post. My wiring diagram, tailored for my 1964 Jaguar MK2 application, is provided below. As the disclaimer above indicates, the wiring description in this post journals what I did for my car. It is not my intention to describe what you should do for your car!

This is a link to a pdf of the wiring diagram and it is also shown in the image below:

Central Locking and Keyless Entry Wiring

A full description of the locking system may be found at the “Remote Control Door Locks web site entry: https://valvechatter.com/?p=9205. The wiring for the system is comprised of two components. The MES Central Locking Control Module operates the door lock actuators. Once that system in properly installed and operating as it should, the AVITAL keyless entry module is added to permit use of a key fob to wirelessly lock and unlock all doors. An added feature of the system is that about fifteen seconds after ignition all doors are locked automatically. 

The following wiring diagram is unfortunately a bit busy. This is a link to a pdf file of the diagram: Keyless Entry Power Locks for Rose Jag MK2 and a jpeg file is depicted below:

Air Conditioner Operating Controls Wiring

A full description of the installation of the RetroAir air conditioning system in my MK2 is provided in the “Air Conditioning” Post. The wiring of the controls and devices for the air conditioning system is depicted in the following diagram:

Rose Jaguar MK2 Air Conditioning Wiring

Rose Jaguar MK2 Air Conditioning Wiring

This is a photograph of the wiring harness provided in the RetroAir kit. In my application I did not use the circuit breaker shown in the image because I wired the blower switch directly to the fuse panel and protected the system at that point with a 40 amp fuse.

RetroAir Wiring Harness Kit

RetroAir Wiring Harness Kit

As the diagram above illustrates, I chose to install a trinary pressure safety switch in the air conditioning electrical circuit. The trinity switch is also discussed in the “Air Conditioning Post.”

Vintage Air Trinary Switch

Vintage Air Trinary Switch

The Vintage Air trinary switch kits combine low and high pressure compressor clutch cut-off functions plus an electric fan engagement signal at 254 psi. The low pressure cut-off of these trinary switches is 30 psi and the high pressure cut-off is 406 psi.

http://www.vintageair.com/Instructions2013/904678.pdf

The switch as supplied has two blue wires and two black wires. Because the switch is located in a right from wheel well and exposed to the elements, I connected the four wires to a waterproof connector purchased from British Wiring, and then routed the wires to their termination points. One blue wire is for ground and the other for fused power. One black wire connects to the compressor and the other to the thermostat controller for the air conditioner.

Turn Indicator and Headlamp Flasher Switch at the Steering Column  and the Laycock De Normanville Overdrive Switch and Wiring

The electric overdrive is activated by a lever switch on the right side of the steering column. Power is derived from fuse position #14 of the CT fuse box. With lever activation a signal is sent to the overdrive interlock, or top gear switch located on the top of the gearbox and then to the overdrive solenoid. A warning indicator bulb is illuminated when the overdrive is engaged. More information about the switch and lever mechanism may be found in the “electrical components” post.

Overdrive Interlock or Top Gear Switch at gearbox

Overdrive Interlock or Top Gear Switch at gearbox

The lever on the left side of the steering column is used in an upward and downward motion to activate the LH and RH turn indicator flashers at the front and rear of the vehicle. When the flashers are functioning an indicator bulb located in a centralized position behind the steering wheel is illuminated in a flashing pattern. The headlamp flasher is activated by the driver pulling the same lever toward himself. This action will trigger the high beam warning light in the speedometer.

Although the wiring harnesses were complete, there were a number of electrical connectors on the harnesses with no explanation as to what needed to be connected where to get the seats functioning.

Seat Wiring Harness and Switches

Seat Wiring Harness and Switches

The seats have seat heaters (upper and lower cushions), a memory feature for the driver’s seat, seat belt alarms, and wiring to permit automatic movement of the driver’s seat to the aft position when the driver’s door is opened.

After some enquiries on the Forums, Bryan Neish came to my aid. He was of great help figuring out what the wiring at each of the connectors did. I know he spent quite a lot of time reviewing wiring diagrams to find what I needed. George Leicht was also helpful. He sent along the wiring diagram that accurately reflected my seat wiring.

I wired the seats to unswitched power at the fuse box to facilitate seat operation before entry or before starting the ignition. I was able to use the original seat wiring harness and bank of switches to control the four motors adjusting the lower and upper seat cushions for each chair. The wiring runs under the center console to each seat. A pdf file of the seat wiring schematic for 1990 may be found here: 1990 Jaguar XJ40 Seat Electrical Schematic

I have yet to decide where I will mount the switches. The image below shows the approximate location of the switches as Ton Tulleken installed them on his car:

SideLights

Additional detail about the sidelamps may be seen in the exterior lighting post. I rewired the original side lamp fixtures and trial fitted them to the body. The rubber “O” rings supplied by SNG Barratt are to thick to fit properly so I replaced them with metric 24mm – 2mm “O”rings ordered from McMaster Carr. New LED bulbs were also fitted in the fixtures. The red 18 AWG wire from the bulb is combined with a black 14 AWG ground wire from the fixture in a vinyl sleeve that goes through the LH and RH valance lighting grommet.

After installing the side lamps I moved to the turn signal flashers. Information about the lamps is contained in the exterior lights post. I re-used the original fixture wire terminals but replaced the power and ground wiring with new. The power wire is blue/green 18 AWG and the ground wire is black 14AWG. The wiring is pushed through holes on the back end of the fixture’s new rubber boot. New vinyl sleeving was also used for the flasher lamps.

Fograngers

More information about the fog rangers may be found in the exterior lights post. The Classic Technologies Fuse box did not have a relay designed into the product for fog or driving lights, so I added a Bosch relay for this function. It is mounted on the original fuse panel in the engine bay on the LH valance. The foglights are controlled by the primary light switch.

Tail Lights

More information about the tail lights may be found in the exterior lights post. I substituted LED bulbs for the original incandescent type; however, the wiring remains the same. In fact, I was able to reuse the original wire leads from each of the bulb holders. The upper bulb is for the flasher with a single wire lead. The lower bulb is for the regular lights plus an additional light for the brakes with a double wire lead.

More information about the lamp may be found in the exterior lights post. The lamp includes one light for the luggage compartment, two bulbs for the license plate illumination, and one bulb for reversing. All original incandescent bulbs were replaced with LEDs. The original wiring harness for the lamp was in pretty good shape, but I constructed a new one with all fresh wiring.

Boot Lamp with new wiring harness

Luggage compartment lamp

As my friend Eric Kriss points out in his MK2 restoration blog, the luggage lamp seemed to be an afterthought to Jaguar engineers. To function the light switch on the gauge panel had to be turned on, but it is often the case that one would want to access the luggage area after the car’s ignition, much less its lights were turned off! Instead of wiring the luggage compartment lamp in series with the front marker and rear tail lights, Eric revised the wiring to move the luggage compartment lamp to its own circuit. To make the lamp illuminate when the boot lid is opened a position sensitive mercury tilt switch is used. As Eric describes, when upright a ground connection is established permitting current to flow to the bulb. When the boot lid is shut, the ground connection is broken so the light goes off.Mercury Tilt Switch

 

Interior Lights

The MK2 as original had six interior lamps: the map light at the central gauge panel, a lamp at the top of each center or “B/C” pillar, a lamp in the cubby box and a lamp on each side of the rear of the car above the passenger seat. These latter lamps referred to as rear quarter interior lamps. My Mk2 will also have two courtesy lamps in the back of the front seat headrests. More information concerning these lamps may be found at the “Interior Lights” post.

As pointed out in the “Interior Lights” post, the replacement center pillar lamps are not exact replacements for the originals. They are operationally superior in that they provide an “on-off” switch at the lamp, and also because they screw, rather than snap, together. They just don’t look quite as nice being plastic rather than chrome metal. Just to check fit and to test the electrical system I did install the new center pillar lamps mounted on their wood bases. An additional grounding wire is used with the new lamp for its switch so there are three wires rather than the original two. For purposes of testing the electric system I temporarily fixed the third ground wire to the pillar as shown in the third photo below.

36 mm festoon bulbs in warm white were substituted for the original incandescent bulbs.The lamps are wired to the interior lighting circuit that includes the interior lamps toggle switch on the central gauge panel as well as the four door switches. The black ground wire is simply attached to the metal center pillar.

I trial fit the new, but as original, rear quarter lamps which required making new plywood mounting frames. Wiring for the rear quarter interior lamps initiates at fuse box to the interior lamp switch on the gauge panel and then proceeds through the LH and RH sills to the lamps. There is also a switch in each door that activates the interior lamps should any of the four doors be opened. I did not use wiring pigtails for these lamps. 36 mm festoon bulbs in warm white were substituted for the original incandescent bulbs.

I am using XJ40 powered seats in my MK2. The seat headrest lights were originally wired in such a way that they too illuminated when the car’s doors were opened. These lights also have an integral on/off rotary or dial switch. Without the central processor of a more modern car it would be all too easy to leave these lights on and eventually drain the battery. Therefore, I elected to wire these lamps to a switched power source rather than a constant power source like the other lamps. I did not use the terminal on the headrest light that would normally have a red/green wire to the door switches.

I was able to use the original door switches in my rebuild. I just rewired each of them with new wire.

The rear door switch is mounted in the rear side of the B/C post or center pillar. The wiring for the switch travels from under the front dash, through the sill and up the center pillar.

The Cubby Box lamp assembly wiring for Lamp/Switch consists of a metal base fixture, bulb, blue plastic cover and a switch controlled by opening the Cubby Box door. More images and information regarding the lamp may be found at the “Interior Lights” post. As with the other interior lamps, the original incandescent bulb was replaced with a 36 mm festoon bulb in warm white. Terminals on the back side of the metal lamp base connect to the fused power source and to the Cubby Box door switch. The image below illustrates the wiring sources and terminations for the Cubby Box.

Some Details on a Few Other Assemblies

The LH and RH Fascia Board Assemblies were installed in the car so as to test the wiring for the speedometer and its warning lights, the tachometer with the internal clock, the “Handbrake “ON” position and brake fluid container level” warning lamp, and the “Cubby” glove box lamp. More information on these fascia boards may be found at the “Dash” post. All gauge/instrument illumination incandescent bulbs were replaced with LEDs.

I first connected the left turn signal flashing indicator, the right turn signal flashing indicator, and the overdrive engagement indicator from the indicators wiring pigtail to the direction indicator/headlamp flasher switch. A ground wire for the indicators was mounted to the body below the dash.

I found it easiest to loosely position the driver’s side fascia board and I then installed the tachometer with its two mounting clamps, a ground wire, the 12 volt power wire, the wire connecting the tach to the coil and the two instrument lights. Leaving the speedometer position open facilitates accessing the LH fascia board outside mounting studs/nuts.

I then secured the LH fascia board to its mounts, followed by connecting the wiring for the handbrake/brake fluid level warning lamp.

I then connected the two speedometer illumination lights, the lights for the headlamp, ignition, and fuel warning lights, and the speedometer drive cable.

Installing the passenger side (RH) fascia board is much the same as the driver’s (LH) side. A sliding panel in the cubby box may be removed to provide access to the studs/nuts of the outside mounting bracket. The wiring for the “Cubby” lamp as shown in the write-up and image above is connected to ground and power.

Fuel Sender

The fuel sender has its own short wiring harness consisting of three wires in a protective sleeving. One wire for ground, one for the fuel gauge (the “T” terminal on the sender for 10 volts) and one for the fuel level warning lamp in the speedometer (the “W” terminal on the sender). The embossed terminal markings are evident on the image below. My sender has an “E” marking for earth, although my grounding wire was fixed to one of the screws used to mount the sender to the tank. While the original harness was in good shape, I made a new one for installation in the Jag when the fuel tank is fitted.

Warning Light for Handbrake and Fluid Level

The lamp is activated by a switch at the base of the handbrake, mounted to a bracket located on the interior floor. See: https://valvechatter.com/?p=3913 under the handbrake post, or by a level indicator switch in the brake fluid reservoir is shown earlier in this post.

Handbrake Warning Switch

Handbrake Warning Switch

The “Warning Lamp Indicating Handbrake ‘ON’ Position and Level in Brake Fluid Container” is comprised of the cover and window assembly, a spring washer on the central terminal post, with nuts and washers. Rubber sleeves are slipped over the white wire at the terminal and the white and red/green wires are contained together in a rubber sleeve of about 4.” The warning light was cleaned and reassembled and a new face plate was installed.

Two wires attach the switch with spade connectors and are protected by a rubber cap over the indicator plunger. I sourced a new canister and indicator switch (cap) from SNG Barratt. The canister is covered in blue painter’s tape just to keep it clean during the restoration build. I was able to reuse the original rubber protective cap. An 18AWG light green wire is connected to one terminal. This wire joins via a 4 way snap connector with an orange 18 AWG wire from the handbrake switch. A single orange 18 AWG wire then connects to the LH Barrier Block Terminal #5B. A dark green wire from LH Barrier Block #5A connects to a 2 way snap connector with a red/green wire on the dash warning light pigtail.

A black 14 AWG wire connects to the other level indicator switch terminal and provides a ground connection to the chassis.
