This is for a 1999 Monte Carlo. My friend purchased a cd player for his car, and we want to install it but noticed that the wiring that came with the cd player is totally different than stock. Could someone tell me if the Chevy stock wiring is all the same? Or give me a how to. I've done this many times, but I just need to know what wires hook up to the others. Seems like more cavalier peopel know about cars so I am asking you here.
