    Default VT V6 PCM Pin/Wire diagram

    I am after the wiring diagram for the PCM, trying to find the speed senor wire and the fault wire from the PCM of a VT V6 1998 can anyone help?

    purple white is speed sensor. no engine light wire, it is run over the CAN network. its all serial data between all the modules and the dash.

    Thanks Mate! is there a number above the purple wire, I think that there is more then one purple wire coming out of the PCM, I don't have it here to look at.

    Thank you

    Here is a VT series 1 3.8L V6 Ecotec wiring diagram for the PCM/engine.

    The attached image may be too small to read as this forum doesn't allow higher resolution attachments. If so send me a PM with your email address and i'll email it to you.

    For the benefit of others, see my posts in these threads for some other VT Series 1 PCM wiring diagrams (if anyone needs these please PM me with your email address also):
