    PCM Pinout Needed

    Sorry to post but I've been looking all night. I'm searching for the PCM pin that houses the EGR input to the VCM.

    I'm hoping it's "unused" on the 02 harness but the VCM can still accept the 5 volt reference. So I can hook up my AEM Wideband for logging.

    If not, that's ok as the pinout would still help me find the AC pressure switch input.

    True.....I'm searching for a diagram of an 02 VCM harness (pinout) & a 99-00 VCM harness pin out.

    If the 99-00 EGR input is "unused" on the 02 car, then maybe I can setup the PID to still use that input and not need a "switch" for my A/C pressure sensor input.

    Not sure if this can be done but if it can it would be nice.

    If I knew how to add a pin to the harness, I think it would work fine. Unfortunately I'm too dumb.
