    Hi All. I'm at my wits ends here. I recently purchased an aftermarket cd
    player for my 87 Plymouth Voyager (3.0L V6) and can't figure the radio's
    wiring harness out. I tracked all the speaker lead wires back and am pretty
    sure what's what there, but I'm having trouble getting power to my new cd
    player. I see that it's on the grey harness, but not sure what wire does
    what. I have looked for about a week now (even bought the repair manual for
    it) and can't find any real time to do any real sort of testing to find what
    I need. If somebody out there knows what wire does what in the wire harness,
    then please clue me in.

    TIA

    Before you get started you will need:
    - A basic VOM meter
    - Manual that came with your cd player
    - Basic understanding of electronics (I'm sure you have. If not get some
    help)
    - Tools (of course)

    Set the meter to volts. With the key off, ground the black lead of meter.
    Test the each wire of the harness. The one that indicates 12v is memory (it
    may be yellow). Turn the key on. Test until you get another wire showing 12v
    (maybe red). This is the accessory power (main). Verify this by turning the
    key off and checking again. The main ground should be black. Set the meter
    to ohms and check continuity between other wires and chassis ground. DO NOT
    touch the first two wires found. You may damage the meter. The 0 ohms is
    ground and most likely black (or green). With the aid of the cd manual, key
    off, hook these wires up to the cd unit, ground wire first. The unit should
    power up when you turn the key on. The speakers will be trial and error.

    There are some posts about speaker wiring which may help as well

    Once you are comfortable with your findings, go ahead and start wiring. Some
    advice: Make Western Union splices, soldered and heat shring tubing. If you
    are doing this, take pride in your work and do a good job. The auto
    installers just twist the wires and tape it up. Don't trust these butchers.
