Engine Harness Variations

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.

If it’s a c60 car and you pass please let me know. I need a good donor.....

Dom, thought you might have a cool project in mind.... or is it just for spare?

Dominick, as you might guess Marc Haibeck has a lot of knowledge about this issue. You might check in with him on this if you have not already. --Bob

Bob,


Good point. Maybe lunch.

Graham,

Yes thank u for chiming in. Knock sensor was definitely on my list.

Also... for your '92.
- The valet key wiring changed from two to three wires for '91 and up.
- The oil level sensor connector was added for '91 and up.
- The EVAP solenoid connector was moved from the chassis to under the plenum in '91.

Like Jeff said, none of these things matter to you. You can just add a 645 ohm resistor to the ECM connector to simulate the Valet key as always in full power mode and avoid the valet wiring error code.

Hey--How about me too! --Bob

Don't forget the up integration of the knock module from 90=91 MY
