Check out www.the12volt.com. They have all kinds of wiring information. I had to become a member to browse certain parts of the site, but it was worth it. Membership is free, and there is info on pretty much every car imaginable.

Color codes for stock radio goes as follows.......

Orange with black stripe = Always HOT
Yellow = Hot when ignition is on
Red = Power antenna
Brown = dimmer
Gray = dash lights
Black = ground

Now the top row of speaker wires are for your rears and the bottom row if for your fronts.

Hope this helps a little

For models '82 to '92 (if you have power antenna)

If not power, then it is probably not even in the harness
