Audio Systems: 1987 ford tempo stereo, ford lincoln mercury, ford tempo

Question
I have a 1987 Ford Tempo. I am trying to put a cd player in it. I got a harness its for a ford/lincoln/mercury 1986-2004. I plug the harness into the clips coming from the car, then I wired the wires from the harness into the stereo wires. The cd player turns on but it has no sound. I also notice that the wires that come from the car are like pink with a blue stripe and none of the wires from the harness have the same colors. I wondered if that has anything to do with it or if I need a new harness. I didnt cut any of the wires that were hooked on the factory stereo I just unplugged them and then plugged the harness into it. If you could help that would be great.

Answer
I would check the speakers and their wiring.
You did not say if this all worked before you started on the CD. If it (all) did, it is probably a simple mis-wiring.

Popper Battery Assembly:
Attach some wires to a 9v battery of different lengths so it will not drain when not in use. This can be done with electrical tape and solder.

Now..  get into a position where you (or an assistant) can see either the back of [or the front of] the speaker being tested.

NOTES:
Tap the extended battery leads to the speaker (only for 1/4 sec or less) and watch the speaker.
During this test, a functioning speaker should move in one direction, then return to its idle position (after unhooking the popper battery).
Do not hold the popper battery on there too long as it will damage most speakers!!!
Just attach it long enough to see the movement.

If the tested speaker cone jumped OUT of the frame (towards exterior of vehicle) the POSITIVE lead on the battery is indeed hooked to the positive for the speaker.

If the tested speaker moved IN (towards the interior), the NEGATIVE battery wire is indeed hooked to the positive side of the speaker.

Simple, (and easy to get used to doing) if you follow the instructions :)

This test will not only tell you the polarity of the wires (from anywhere, including the dash), but will ID the speaker wires, the speaker locations, AND tell if the speakers move and create sound when electricity is applied.
