    2007 cts connector c104

    Hello, I am the owner of a local shop here in San Diego. We are trying to help a customer that "Fixed it himself" before coming to see me. This customer had changed the A/C system pressure switch, since it had been leaking. After doing so he came to my shop to have the freon replaced (yep, you loose it all when you blindly unscrew that sensor...) Anyway, after pulling a vacuum and recharging the system we found the A/C clutch inoperative...
    So I hook up the scanner, the A/C is reporting 0 psi... Yet my gauges show 75 static.

    This is where it gets fun, the A/C pressure switch had been leaking for a while, and the oil traveled back along the wiring harness. For whatever reason, the A/C oil decide to attack the insulation of all the wires. As we untaped the A/C pressure switch wires, and the wires to the 24 pin black engine to IP harness connetor (C104) we found the insulation degraded and falling off all of the wires, they all were stuck together in a big mucky mess.

    I have never seen A/C oil, ester, or PAG cause this kind of destruction. My guess is that GM started using something new for the insulation on the wiring harnesses.

    Anyway, I am in need of a connector end view and pinout diagram for connector C104, there are several purple wires, that appear to be the data signal wires from differant modules, and two grey wires that I believe are simply 5 volt reference wires. I asked my local GM parts guy for this diagram and his computer station did not have access to the diagram I requested.

    I called Cadillac, and have had no response.

    Can Anybody provide me with this Connector End View and Pinout? VIN number is; 1G6DP577170132257

    Thank You, DroctorK

    There is a Cadillac customer rep here that you can contact and you can also send a PM to RippyParts. You may be able to get some help from them.
