Instrument pod connector wiring and PCB connectivity

awatkins · Mar 30, 2020

The color A/C wiring diagram shows the colors of the wires going through the 4 or 6 pin connector on the back of the left and right instrument pods, respectively. It also attempts to identify which pin of the connector each wire uses. However, if you match up the colors with the wires in an actual car you will find out the pin number sequence implied makes no sense. To resolve this I have documented the color positions for each connector as follows:

LHS Connector Pinout
Looking at the back of the connector on the harness, with the bevels down, and going clockwise from the top left, the pinout is as follows:

# CW from Upper Left	LHS Color	Function
1	Green/Black	“Fari” light
2	White/Black	Instrument Illumination +
3	Pink	Clock and Fuel Gauge +
4	Violet	Fuel Level Sender
5	Yellow	“Luci” light
6	White/Black	Fuel Level “Reserva” light

RHS Connector Pinout
Similarly, the RHS pod connector is as follows

# CW from Upper Left	RHS Color	Function
1	Yellow/Black	“Vent” light
2	White/Black	Instrument Illumination -
3	Red/Black	Oil Pressure Sender
4	Pink	Instrument & Light B +
5	Gray	Oil Temp. Sender
6	Brown	Coolant Temp. Sender
7	White/Blue	“Aliment.” Light
8	Gray/Black	“Freno” light

More directly, here are photos of the two PC boards with the traces labelled.

Very nice and useful finding. Thanks for sharing.
