Hey, finally got around to fixing it. And yes, the 12V switched wire was the culprit. I switched out the scosche harness for a metra one to add switched power and the steering wheel control harness and it works fine. I want to add a backup camera now, but I'm not sure of the wiring, tell me if I have this correct. I'm using an OEM tailgate logo camera that has power, ground, video, and something labeled reverse anode output. Ground goes to ground, video is plugged into the H/U, the reverse wire goes to the reverse wire in the H/U harness, and power goes to either constant 12V or switched 12V?
