    You are right.
    It's pink.

    I only have black and white diagrams.
    P = Pink.

    You are correct.

    V = Purple. My fault.

    I see one difference, The IC4 connector.
    We're going to likely have to go to the ECM and test powers.

    @J4R did you see if the pink wire had power?

    If not, we can move to the ECM.
    As we need a CEL on the dash.
    It's not going to crank with out the ECM being online.

    Wasn't sure what C4 and C17 were?

    Still think the ECM is the issue. Which could be confirmed by the Neutral Safety switch check. Or the IM1 connector. (I don't have a location on that)

    I'm going page by page to see if there are any differences between 05 & 07.

    Does the 10A EFI No.2 fuse have power with key on?

    The ECM controls the relay that feeds that fuse.

    Works for me.

    Check the 10A EFI No.2 fuse.
    You can check the safety switch if you want too.

    That's fine, I just don't have much time during the day to look at diagrams and such.

    I'll put together a list of PCM powers and grounds to test and post it though.
