97 Nissan Altima Wiring

I'm having trouble getting my CD Head Unit to work. I dont have a RED / green - illumination wire. What should I do?

I am replacing the stick tape player head unit. I am putting in a Aiwa Cd Player. And i am not using a wiring harness.

First off you need a test light so that you can find the proper wires. If you are looking for an illumination wire all you need to do is put the parking lights on and off while you have the test light to the wire. If there is no output going to the radio you must catch the parking light wire elsewhere. You can catch it at the parking light switch. It is better however to catch the wire at the dashlight dimmer switch so that the radio lights will dim along with that switch. Either way it will work fine. Let me know what kind of car you are working on and I'll tell you the wire you need to find.
