I have the metra 70 2103 harness for my 05 cobalt ss this is the second harness I've been through. Have all wires color matched and have it fuse tapped to the wiper and tried the sunroof. I get no sound out of the speakers. Nothing. I don't know if I need to put certain wires that aren't color cordinated together or not. The system is jvc kw av61 for reference
