I Bought a pioneer AVH-P3300BT for my 2005 Grand Prix GXP. I need to know what kind of wiring harness and antenna adaptor i need for before i can hook it up.

Well hello H-town! Do you have a factory amp? Ive never done an 04+, but if it has RDR you will need this harness to retain your door chimes. But if you use your onstar, it will not work. And you have to relocate the factory radio.
