Ok here goes ....my son went to wal mart and bought a new am/fm/cd/ipod/bluetooth/etc..for his 2001 Cavalier.The people told him he needed part number scosche gmda.We take dash and radio out and the harness plug isnt even close.So back to wal mart and we get a scosche gm035.Well the plugs are the same but it looks like the wiring on the factory plug dosent line up with the harness.Is this the correct harness or do I need to switch wires around?If so could any one tell me where to find factory radio plug schematic?Thank you for your time.

There is a post for this here somewhere, something about a chevy tracker harness.. It's in the sticky above electronics forum
