Im trying to figure out the wiring for my AC system after swapping an SR into my S14. The AC is intact and compressor and system were functional before installing the SR. Im using a KA compressor on the SR so nothing was really disconnected in that sense hence why all I believe to be the problem is the wiring.

I have tried to reference the F4 and M63 plugs inside the car where I think the problem is but looking at the pdfs that I have seem to be getting me no where since some of the info I have is conflicting. For example, I see no AC switch on the M63 plug and its on the F4 plug.

FYI- When I push the AC button the light doesnt come on.

Has anyone got the AC to work in the S14 and could help me out with pinouts and what I should be looking for?

on the f3 conector (big white plug under dashboard near passenger foot well , you know the one you have to splice into to make your engine swap work) you need to splice together the following cables pin 16 yellow/ black to pin 43 or 46 (cant remeber now im at work) black/pink. and what do you know voila it works, push the a/c button a/c turns on, pust it again it turns off. 2 friggin wires, it was staring me in the face for like a week before i tried it , it seemed to easy, thats it just sauder those two wires togerther and ti will work like stock.

I've also wired in the fans and the IACV to get the idle to kick up when I turn on the AC as well. FYI, this is an S13 SR into an S14 Zenki.

Im a bit confused here. The F3 connector is where? I thought the big white plug that everything is spliced into is labelled F4? Could this be an S13 S14 thing?

FYI, I checked for a yellow/black wire on the F4 plug and no where to be found.

Om1kron, thanks for pointing me to that thread in the first place.

OP, look in Om1kron build thread that he recently closed. Wayne posted the pinout for the plug.
