I was curious, what are the color codes for the wires in a Pontiac Grand Am's stereo? I am installing an aftermarket radio and I do not know what the colors are for. I do not have a harness either. Thank you!
Please don't cut your harness ,you should get a harness connector kit due to damage that you can cause just clipping wires .you will be money ahead to get kit made your your specific car ,I'm a gm tech and I get a lot of those cars in with damage electrical system due to bad stereo install . My email is [email protected] any questin please feel free to ask will save you a lot of problems ,I will send you pics of diagrams that way because they don't show up well on this site .
Go to the12volt.com. awesome website for all your wiring needs. that's what i always use.

Go to this site...very helpful. You have to run your own power wire to power the aftermarket radio. I just finished an install 20 minutes ago.

attach both power and illumination wires to constant on car wires.... only way to have switched power is connecting the switched/ignition wire to a fuse
