The AC control module is located up inside the dash.


You can see it if you drop the glove box out of the way.


It's a small black plastic box with the big (C2) connector on the back and the smaller (C1) connecter on the side.


Note AC module pin C2-8. Under full-throttle acceleration the PCM sends a cut-out signal to the AC control module which turns off the AC compressor. This frees up engine horsepower for passing. This composite drawing is downloadable at: https://www.dropbox.com/s/jcx13y6p8e...osite.jpg?dl=0



These are the C1 pinouts


These are the C2 pinouts.
