Engine Harness Variations

[WVZR-1]

In MY '90 there would have been 2 harnesses, 1 for C60 and the other for C68. A tag near the connector for C100 for C60 would be 0375 likely and C68 0376. There's an obvious visible difference where the C68 would plug into the Blower Control Module or the C60 just a conventional Blower Resistor.

And so a 92 would be using the C68 connector for the Blower Control Module since the 92 did not come w manual A/C controls, correct?
Anything else you can think of? I can think of the knock sensor. ASR?

You need to compare the 'pin-out' to the C100 of your '92 to whatever you have the opportunity to buy.

8A-202-13 gives you that 'pin-out' for your '92.

I didn't bother to compare to '90. It's something you need to sort!!

If the '90 was from a C60 car it would require modifications to be used on any C68 car. Here is the '90 C100 'engine side'. You need to compare cavity population and each circuit mentioned in likely both FSM.
