[QUOTE="Rothy, post: 8720283, member: 681299"] New guy here. I came across your forum searching for a solution to one of my systems problems. After digging and not finding my answer (but finding questions regarding the opposite of mine) I thought I'd join and see if I can get some help. One of my problems currently is that my head unit powers on/off with the headlights. It will turn on/off with no keys on if you turn headlight switch; if the key is in acc or on the headunit turns on and stays on regardless of headlight switch position. My Amp also has constant power (gw-124 w/ rzr1-2500d). I tapped the remote into the larger gage orange power wire in the factory harness like I did my old car. The new truck has an orange wire on #1 pin (top left) and a thicker orange wire in the pin directly beneath it. I tapped both after discovering my problem and both have constant power... So I'm confused now. Is this expected? Where can I run remote wire at least to power on with accessory in the harness? 2005 Chevy Avalanche Z71 with Bose premium sound and navigation. Truck has factory sub and Amp. Headunit is jvc kw-v350bt. The PO had a scoche(?) factory adapter/interface in it for his Pioneer headunit, that was a nightmare. I am still rewiring the catastrophe he had to make everything work properly and so far my only issues remaining are this and no steering wheel controls, and the fact that it seems the truck changes volume/EQ/settings on its own. The latter has me lost; I am leaning towards the factory Amp but that's what the adapter was for?? One other question that may help diagnose this: under the dash my factory radio harness has a Gray female connector, a green male connector, and a Gray male connector. This is all "factory" if I plug my unit into the gray female and everything else is disconnected it powers on and everything works.
