OK, need some help guys, i'm in the middle of replacing the OEM Radio with a kick ass Sony (Sorry Pioneer, pics later once install is finished). In the searching I was doing for the cheapest harness that would work and retain steering wheel controls and I didn't care about Onstar I came across a listed that listed the Factory Amplified so long as it wasn't certain RPO codes I found the Scosche GM2000SW, in the listing photos it says its compatible with 02-09 TB's as long as you don't have the RPO codes Y91, Y92 or Z75, none of which I have, all the codes I decoded on mine that had anything to do with the stereo where UQA, UK6, UC6, and ZQ3, I get it all wired up, radio powers on, got the door chimes work but NO MUSIC, whether I connect the remote wire to the factory harness or not I get no sound. did I get the wrong harness? if so which is the right harness?
