The diagrams provided below depict the wiring to/from each of the switches in the panel. The purpose, operation and in some cases repurposing of the switches is described in a previous post “Gauges, Instruments and Switches.” One addition to the panel is a small chime that is activated if the headlamps are left on when the ignition is off, but the driver’s door is opened.

As with the switches, the gauges are explained more fully in the “Gauges, Instruments and Switches” post.
The following images depict the wiring for each of the four gauges:
