Custom Wiring Harness Installation – Part One

Posted on by

We sent our custom made wiring harness to Rhode Island Wiring Services to have the harness covered with a cloth braid using a royal blue double tracer. The cost was $5.25 per foot with an $8.00 machine set-up fee. We were very pleased with the results. Pardon the messy work bench – it gets that way from time to time!

Finally, the time has arrived to install the harness in the car. The first step was to get the end of the harness though the firewall grommet. Not easy with the Deutsch connectors attached, but we got them through.

The next step was to connect the three wires in the harness to the small power supply fuse box. One thirty amp wire feeds the Ignition bank in the fuse box, the other thirty amp wire feeds the accessory bank in the fuse box and the fifteen amp wire feeds the lights bank in the fuse box.

Then it was a matter of connecting the wires to the four banks of fused terminal positions in the Classic Technologies relay/fuse box.

We pulled all of the fuses in the two fuse boxes and will add them back one at a time as we test the circuits upon final installation.

Next, we turned to the group of wires that run to the front of the car along the RH valance. Wiring for the coil, the hydraulic brake switch, the radiator fan, the radiator fan thermostat, the horns and the lights are in this bundle.

We used stainless steel clips to secure the wires to the valance. A smaller 3/8″ clip will be used to route the capillary tube for the water temperature gauge and sensor.

We made a little bracket to support an 8-pin Deutsch connector at the front of the valance. This connector will mate with an 8-pin bonnet connector to deliver power to the headlights, flashers, running lights and auxiliary driving lights if we decide to mount them.

We then installed the twin Hella horns and made the wiring connections. This did involve using a four way bullet connector to receive and supply power to both horns. A double spade connector was used to facilitate the wiring connections for the ground wires.

The next wiring connections to be made were for the wiper motor. Duestch connector “H” is used to connect the wires from the wiper motor to the Wiper Controller mounted behind the dash. The three wires, encased in shrink tubing, come through the firewall. The green wire connects to wiper motor terminal #2 and the green/black wire connects to terminal #1. A black ground wire connects to terminal #3.

The next item to wire was the ignition coil. The yellow/green wire from the harness connects to the (-) terminal of the coil. The white wire from the harness connects to the (+) terminal of the coil.

The heater blower has two black wires from the fan motor. One of those wires is connected to a yellow wire from the harness with a spade connector. The other black wire is ground and is screwed to the chassis.

The hydraulic brake switch is mounted on the RH engine bay valance. A teal green wire and a brown/green wire from the harness connect to the two screw terminals on the switch.

The brake pedal brake switch is a custom addition to the Bugeye. Details on the switch and its mounting bracket are highlighted in another post: https://valvechatter.com/?p=14351

Two wires from the harness, a green wire and a dark green/orange wire, come through the grommet in the LH footbox near the dipper switch and connect to the switch at the pedal.

The Dipper switch wiring was completed next. We had a little issue on this because we cut two of the wires a little too short requiring the use of bullet connectors to add length to the wiring to the switch. However, while space was tight, we were able to make all of the necessary connections.

There are three terminals on the dipper switch. A power-in terminal, a low-beam terminal, and a high-beam terminal. One has to look closely to find it but the power-in terminal is marked with an arrow on the switch molding. The blue wire from the harness connects to this terminal via a bullet connector.

The blue/red wire is connected via a bullet connector to a blue/green wire (ran out of blue/red) and then to one of the remaining switch terminals – it doesn’t matter which one.

Three wires connect to the remaining terminal on the switch. The blue/white wire is for high beam operation, the green wire is for the high beam warning light in the speedometer, and the blue/yellow wire is routed to the toggle switch under the dash for the driving lights. These three wires connect together via a four way bullet connector, with one blue/yellow wire then connecting to the terminal on the switch. A bit confusing, but the photo helps.

The fuel pump wiring connections were then made. The teal/purple wire from the harness was connected to the black wire at the Facet pump with a spade connector, and the white/purple wire from the harness was connected to the SU pump with a spade connector

Smiths Heater Refurbishment & Trial Fitting

Posted on by

In a Bugeye engine bay, the Smiths heater box and blower are quite prominent so it is important that in addition to functioning well, they also look good! This Episode Forty-five video of the Bugeye Restoration shows the refurbishment process. The original plan was to use the heater box that was in the car, but in the end we decided to replace the box with a unit manufactured by Ashley Hinton in the UK. 

The matrix was flushed and checked for leaks and the blower motor was tested. The unit is now ready for installation in the car.

Upon initial fitting of the heater box it was quickly evident that the heater box was sitting too low relative to the blower fan unit. In our case we are using a blower unit that was originally in a big Healey, the heater box as previously stated is a new reproduction made by Ashley Hinton and the previous owner installed a new battery shelf so it is difficult to say where the misalignment may have originated. Perhaps a combination of all three!

At any rate, we had some 1/8″ black ABS plastic sheet laying around the garage so we cut three pieces to size and then glued them together with ABS glue. We then used a 1 5/8″ drill hole saw and a saber saw to cut the air circulation hole in the center of the new shim plate. To this we attached 1/2″ closed-cell rubber adhesive-backed insulation and screwed the shim to the bottom of the heater box. We were then able to bring the components into alignment when mounted on the car.

The dashboard heater switch was installed in the dash and connected to the blower fan. once connected to a 12 volt power source we were able to successfully test the switch and blower motor. 

Finally, we installed a 10-32 nut sert into the RH engine bay valance to locate the large “P” clip for the heater/fresh air trunking.

Chapter 84 Week Fifty-Four December 24, 2007

Posted on by

Today (Monday) is Christmas Eve and there is much to be done, so only a little Healey work will happen on this day, but I had a good week. I did manage to install the rubber buffers on the front shroud sill bonnet opening. Three on the left side and two in the right plus the long strip to protect the carbs from the weather. My long strip is cut into two pieces to account for the carb access panel. The buffers are held in place by copper-colored split rivets and flat washersthat are pushed through the mounting hole and then bent over.

The next task was to fit the front wings to the superstructure. I began with the RH wing, thinking it would be the more difficult of the two. First, I tapped the wing clip nuts onto the wings. Three shorter nuts and bolts are used for the front of the wing, below the headlights. With the help of my wife, who held the wing in place, I installed the rearmost and forward most bolts.

With those two holding the wing in position, I then began to install the other bolts working from the front to the rear. Each one was hand tightened enough to get them started, but with enough room to install the wing beading. The fourth nut/bolt from the front requires Houdini to install. I finally accomplished it after loosening each of the four bolts securing the heater blower and then disconnecting the large fresh air hose from the blower. With the hose loose I was able to access the bolt for the fourth hole.

To protect the paint while installing the beading, I ran a strip of painter’s masking tape on the shroud and the wing parallel to the beading.

Beading Installation

After carefully spreading the beading folding tabs so that they were evenly distributed across the wing, I pressed it in place. Once again, four hands come in handy!

With my wife applying downward pressure on the beading I tightened each bolt/nut until the beading was locked in place and the top of the wing was tight.

Then I tackled the three fasteners below the headlight. These are much easier to access. Again, I loosely attached each of the three and then inserted the two plastic beading pieces between the panels and tightened down.

Next were the three 1/4” x 3/4” long hex head bolts used to secure the bottom edge of the wing. Finally, the 3/8” sheet metal screws were used to fasten the wing flanges to the hinge pillar plate. The heater blower fresh air hose was reinstalled and the blower’s four mounting bolts tightened. A little red touch-up paint on the lower bolts and pillar screw heads and then it was on to the LH wing. NEXT TIME I WOULD WAIT TO FASTEN THE WING AT THE BOTTOM UNITL THE DOOR IS INSTALLED. THERE IS FLEX IN THE WING AND BY MOVING IT UP OR DOWN SLIGHTLY ONE CAN BETTER MATCH UP THE WING CURVATURE WITH THAT OF THE DOOR!

The LH wing was a little easier to install in my case because of the carb access panelI had cut into the shroud! The difficult nuts/bolts on the LH wing were the rearmost two because the wiper motor restricts access to the locating holes and hardware.

It was a good feeling to have all four of the body’s wings in place.

The next task was the installation of the scuttle seals that I had ordered from Bill Bolton. These are reputed to the best available, and the fit does seem to be quite nice. As I was working on the seals and dash pad I had a visit from grandson #2, Shane. As the image shows, he seemed right at home in the Bloody Beast.

Fitting the scuttle seals was not as difficult as I expected. The job was made much easier by following directions: Scuttle Seal Install Rich Chrysler along with those provided by Bill Bolton.

I then installed the dash pad, along with the hot air outlet defroster masks, the mirror, tonneau turnbuckles, and the stud for the tonneau cover.

Once the dash and accompanying hardware was installed I was ready to begin the door installation. I first attached the door check strap assembly to each side. Then I taped all the edges of the wings, sills and doors with painter’s masking tape for protection.

My son John (23 years of age and strong) lifted the doors in place and I ran in the door hinge screws. This job was actually easier and less time intensive than I imagined. Of course, I still need to adjust them for proper fit. I had previously attached all the door interior upholstery, trim and hardware which was much easier than installing it all on the car, but it did make the doors quite heavy.

Next on my list was the installation of the headlight buckets, headlight bulbs, and the chrome lens retaining rim. It wasn’t necessary, but I jacked up the front of the car and temporarily removed the splash shields and the tires to give easier access to the rear of the headlight buckets. I experienced a little difficulty with mounting the trim rim but eventually got it to lock into place. Then I secured the parking/flasher light assemblies to the car with the three small machine screws and nuts, and put the clear lens in place.

I thought I would check out the fit of the grill and immediately noticed that the horns were preventing the grill from sliding into place. I did not have the original horns and I am using later replacements (these are deeper). I ended up switching the LH and RH units and placing them inside their mounting bracket and this seemed to give me the space I needed for the grill. At some point I would love to find the proper horns!

Now it was on to the tow hook/driving light bracket from Cape International. I bolted the brackets into place and fit the Lucas 570 SLR- 5” driving lights, attached the wiring and tested the lights to find them working beautifully. I had previously installed the light relay, an indicator light and the wiring so that the lights only come on when the bright beams are used.

Auxiliary Driving light bracket and tow hook

My final work for the week was the installation of the three pieces that comprise the front grille. These were fixed to the car without any issue. The splash panel brackets on either side of the car were fastened to the outside grille mounting brackets.

Other than installing the finished motor and the body components I am now down to just a few bits here and there. I am starting to get excited about the finished product after so many months (years actually!) of hard work.

At the factory the two rubber buffers that mount to each of the wheel arch assemblies  were fastened to the assembly before painting the tub, but I installed them after painting to make sure that all surface areas were covered well with paint. Copper split rivets and washers are used to fix each buffer to the wheel arch.

The front wing support brackets were added next. I carefully attached them in the same positions they were in for panel fitting.

The bonnet support plates were added next. These were not fastened tightly so that they might be adjusted easily after the front shroud was installed

To avoid losing radiator coolant I decided to add a coolant overflow reservoir tank to the Bloody Beast. I fabricated a bracket to mount it to the superstructure and ran a clear hose parallel to the wiring harness that runs down the RH firewall brace.

I purchased a stainless steel braided hose for the clutch slave cylinder from Moss Motors. I attached it to the new Lucas slave cylinder and then inserted it into the retainer clip on the frame to screw it into the clutch pipe running up the RH footbox. Doug Reid aka Mr. “Finespanner,” fabricated a short bleeder pipe for me that will mount on the bell housing making it much easier to bleed the clutch in the future.

The fresh air hose installation was made easier because of the “pre-fitting” done prior to the tub being painted. The LH hose quickly went into place and the clamps and bracket for the control cable were all tightened.

The modern heater (contrasted with the original Smith’s heater radiator box) that I am using from Cape International has it’s own blower fan, and therefore, the original heater blower can be used to circulate fresh air into the passenger side of the cabin. I installed an air intake assembly upside down and close to the front end of the LH hose so the the control cable from the cockpit heater panel could be used to open and close the air inlet valve assembly. It all works like a charm. Perhaps now my victims, I mean passengers, won’t roast while on long sojourns in the summer.

RH Fresh Air Hose to Blower

The bonnet catch lever and its connecting rod were then secured to the frame bracket with stainless split pins. Then the anti-rattle spring hardware was attached to the bonnet remote control rod.

Although the original equipping of the Healey did not provide for any type of screen for the front of the RH fresh air hose (other than the one in the heater blower), I purchased some plastic flexible screen and attached it to the hose with a clamp. This will hopefully keep bugs and small children out of the cooling system. Time will tell how this works.

Screen for RH fresh air Hose

Adding fluids and lubrication was next on my list. Many on the email list had suggested using a HELP product #42072to replace the original rubber gasket in the brake reservoir cap to avoid brake fluid “spray” getting to the paint. I purchased and installed the gasket and it does fit perfectly and provides a nice tight seal to the canister.

HELP # 42072 diaphragm gasket

I then proceeded to purge the air from the brake and clutch lines by bleeding the system. It is not that this job is hard, but I hate it! Brake fluid is messy stuff and paint does not like it.

Bruce at Healey Surgeons had added steering lube to the idler when he rebuilt it, but now was time to add the lube for the steering box. I used Penrite Steering Box Lube. It is thick stuff. I set the plastic container in a pot of boiling water for a while to heat it up and therefore “thin” it. The container comes with a very handy applicator tube that fit right in the steering box hole. I filled it up and then tightened the fill nut. No leaks the next morning!

Penrite Steering Box Lube

I found out the hard way that filling the rear axle with gear lube would have been easier prior to installing the rear seats, but with the aid of a clear plastic tube I was able to get 3.6 pints of Valvoline 90 weight gear lube into the rear differential.
