1996 vs 1997 wiring difference

[Allmostall]

Does anyone have the wiring schematics for the 1996 C130 connector
vs the 1997 C130 connector?

You have to swap two pins....

One is for the AC clutch, and the other is for the OBD data port.

Pins 5 & 10 need to be swapped - then the colors will match up.

What about grounding the AC compressor?

I believe the ground pin is unchanged. I've had 0 issues over about 50K now with this rewire on my car (a 96 with a 98 harness).

Pin 8 on the engine side has to be grounded to ground ac clutch.
