2000 Chevy Cavalier radio wiring

go down to your local radio store and buy a radio harness all you do is plug the harnes to your car harness that way you dont cut the original plug and at the other end just match the colors

You will need either a radio delete module or a radio relocate kit. The original radio is a Class II data bus unit that must be retained in the vehicle or substituted with a module to retain the integrity of the data bus, chimes and other functions. The modules are the way to go as they take care of the chimes and also supply a ignition source of power for the new radio. They will plug into the existing harness and give you labeled wires to hook into your new radio. The wires colors may even match the new deck's.sparky
