    Ok, so If I connected 12v to the AC wire from the ECM, this in theory should then increase the idle?
    If it does, then I could Mcgyver up a "fast idle" switch by running that AC wire to a switch. ...

    [QUOTE=1project2many;74246]I'm sorry, but I seem to be having trouble seeing the relay or any of the wires attached to it. Maybe you have a wiring diagram and can match up wire colors?

    Sorry...
