Thread: PCM Pinout Diagram

    PCM Pinout Diagram

    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.

    I think I have the PCM Pinout @ home. Not sure if you can wait though.

    LS1 PCM wiring harness diagrams

    Here are a few that might help, and a few for reference. If you have a wideband controller with that unit, all you need is an accessory voltage to power the unit. I suggest splicing into the VCMs ignition controlled regulated power supply, J19. Run a multimeter over the PINS to determine what voltage it is at. Thats how I permanently wired up my Dynojet wideband.

    Attached diagrams:

    VCM knock sensors
    VCM power
    VCM ignition system
    VCM O2 sensors
    VCM aircon with climate control

    Those are helpful but only 1/2 of what I need. Strange I have the factory service manual for my 02 but there isn't a pinout for the factory VCM.


    The A/C reference pin is my Plan B.

    My plan A is to "hopefully" use the EGR pin as a 5 volt input to my VCM. Now, that is if:

    A. the wire is still there in the 02 harness.
    B. the VCM will accept the data
    C. I can create a PID in HPtuners to use that input (EGR) even though the O2 doesn't have EGR. Yes, all very far fetched and I will probably need to use the AC 5 volt reference. Fine I don't like it but it can be done. Just less easy.

    It's fairly clear that if I knew how to PIN out the wiring harness that the VCM would accept EGR input, however the harness IS not pinned out on my 02. So I went the easy way and used the A/C input for now. If I end up meeting somebody that can do it for me or can show me how to pin out the factory VCM harness I would for sure. If somebody out there can, and is using a wideband input to the A/C pressure sensor input because you don't have EGR you may take a look it's PIN 47 on the blue harness.

    pinout EGR

    you can use the pinout location of the 01.
    hope this helps...
    im going to use the fuel tank pressure sensor for my wideband logging.
