I'm trying to graft a USDM wiring harness into a EU wiring harness so I can use the USDM A/C heater control.

I have both harnesses and wiring diagrams of both. I also have the entire A/C units of both models.

So my plan is to isolate all the parts of the USDM A/C system and figure out where it communicates with the rest of the car and then try to depin the wires and connect them to the corresponding plugs on the EU harness.

I have now my first problem.

The USDM A/C heater control plugs consists of plug D (20 pins) and E (10 pins).

When I turn to plug E all but 1 pin is accounted for by the wiring diagram on CYGNUSx1.

On pin 4 there is not supposed to be anything. But there is a green wire with some silver spots. It goes to junction block 1 plug 1N pin 6.

Does anyone have a wiring diagram that shows what pin 4 on the E-plug does?

Also the EU wiring diagram I have doesn't seem to fit with what I have.

So does anyone have the A/C wiring diagram of a 1991-1992 USDM and 1991-1992 EU models.

Funny how you sometimes figure things out just after making a post.

The pin 4 on th e E plug is on the Tail Lights and Illumination page.
