How do you match the wires for a cd player of a 1986 chevrolet celebrity?

Answer 1

Assuming that you have already had a stereo in the car, try this. Start with a wire pair (positive and negative) for a speaker, place one of the wires on a nine volt battery terminal and hold it with your finger or a piece of tape. Then scratch/rub the other wire (speaker wire pair) across the other battery terminal. This scratching/rubbing will produce a static sound out of the speaker that is connected to the wire you are testing. label this wire set with where the speaker sounded off (right rear, or left front, etc.) Repeat this test with all of the speaker wire sets until you have found and labeled each speaker. Next you have to identify the two power wires, the ground wire, and the power antennae wire. The power antennae wire is usually blue. The ground is usually black or can be jumped (with a black wire) to a bare metal bracket under the dash with a self taping screw. The two power wires that remain are battery direct 12V, and switched 12V power. To test which is which, turn the ignition key OFF and remove the key (this requires that you have the car battery connected). With the key off test for 12 volts with a multitester or a test light by touching the ground lead of your multitester or test light to bare metal under the dash and touch the positive lead of the tester to each of the remaining two wires. The one that produces 12V on the tester is battery direct and should be connected to the "memory"/"battery" positive wire of your CD deck. Now put your key into your ignition and turn the ignition switch to "acc" or to "on" NOT "start". Now test the remaining wire for 12 volts in the same manner as above. If it produces 12V now with the tester and not when the key is OFF, this is your "keyed" or ignition" or main power wire. This wire goes to your ignition power wire on your CD deck. Note, If you want to listen to your stereo without the key in hook both of the CD's power wires to the "battery" wire from the car. THIS will drain you battery to death if you leave your stereo on, so be aware!
