I was wondering which wires are which to hook up an after market stereo in my 1991 plymouth laser. i need to know what are the power wires and the speaker wires on my stock wire harness.
I don't have the exact wire pinout, but I can offer you a generic method. Usually wires in an automotive wire harness that are Red, are power.
I would suggest you buy a cheap multimeter, (If you don't already have one), and set it to the DC volts-50 volt range. They have multimeter's that are relatively inexpensive. $10 or $12 dollars.
There will be a Red lead to a probe, (Positive), and a Black lead to a probe. (Negative) Hold the Red lead to the red wire. Touch the Black lead to any good ground. Any clean of paint, metal surface on the car. The needle should go up to 12 volts on the DC scale.
Ground wires are generally Black or Green. Should you see a Green wire with a stripe on it, this is not a ground wire.
Wires that are of a solid color and have a stripe on them, are usually speaker wires. They will be in pairs. There should be a wire of a solid color with a stripe on it, and a wire of the same color, but no stripe, to make up one pair. One pair is for one speaker. For example:
Blue color wire with a White stripe, and a solid Blue color wire.
There may be two pairs of wires, or four pairs. Two speakers in front, two speakers in back, for the four pairs of wires.
After you find the power wire, and have it attached to the stereo, plus a ground wire, I suggest you make sure ALL the other wire ends are not touching each other, on the stereo. Put a small piece of Black electrical tape on them.
Take one pair of speaker wires, from the car harness, and attach them to the stereo. Turn the stereo on, and see which speaker wires you have. Move the Front/Back, and Left/Right controls.
Now it's just a matter of finding out the correct hook ups for those wires. Match them up.
