Wondering if anyone has any info on the connectors between the PCM and the engine harness. I can find info on the 60 pin connector to the engine all day long but no luck on the connectors between.

I did a MAF conversion on my 90 F150 5.0 chassis that is running a 5.8. Using a A9P mustang ECU so the trouble only code left to deal with is 85 for CANP for which the truck was never equipped. I did find where ECU pin 31 went to the white forwardmost connector for the return using a meter, I need to find where the supply is. Finding where the EGR is would help clean things up as well.

 

There are no pin outs for C101 or C106 in 1990 in the Ford manuals. The only place to get them would be the large fold out wiring diagram.

But C101 and C106 in 1990 are both located at the rear of the LH fender apron.
The CANP is in C106 and is a GY/Y wire number 101.
The EGR is in C101 and is a DG wire number 350.

 

If you have it could you send me a pic?

 

No I do not have the 1990 large foldout diagram. Only the 1990 EV&TS manual.

C106 is a Black 8 pin connector located at B-9 in the below diagram.


C101 is a Gray 8 pin connector located at B-10 in the below diagram.
