    MAP Sensor wires...

    Three wires.....
    1. pinkish/white stripe
    2. blue/black strip

    3 green/red stripe

    Which one is the signal output wire?

    ...and was wonder what the other ones go to/do.

    But right now I need to know the signal wire.

    Guessing that pinkish one is signal. Black/blue is sensor ground. Green/red is +5v

    Power, signal, ground, in that order if I'm not mistaken.

    Green/red tracer is signal to computer, violet/white tracer is 5v power in (also feeds TPS), black/light blue tracer is signal ground (which, incidentally, goes to the computer, not directly to chassis).

    Re: MAP Sensor wires...

    See...couple others told me the other way around.
    violet is signal and
    green/red is 5v.

    Re: MAP Sensor wires...

    I believe it's the same for all the cars. dark green with red tracer is the signal. Violet with white tracer is the power, and black with the light blue tracer is the ground.

    Re: MAP Sensor wires...

    I decided to just buy the kit with the built in map sensor and not needing to know.
    Even the Chrysler wire book says violet is signal...so now I can go forward with my
    project and not work about the right wire.

    Re: MAP Sensor wires...

    What I posted should be correct. It's the same for the 87 cars too.

    Nope, what I posted is correct. I've wired several like that.
