P.S. The harness from CC for your car should be MET 707001, unless its an 89-94 in which case its MET 701743. If youve got the 00-03 with the infinity system, its gonna be a bitch because the antenna wire goes to the amp, not the head unit, so you gotta run new wires from the amp to the head unit, not to mention if you want to bypass the amp to use the head unit power.
