[QUOTE="cornick, post: 8849402, member: 689336"] Ahoy! I'm fairly new to wiring so please be nice. ;) Trying to wire a new head unit (no name brand) into a 2005 Buick Lacrosse but having a few issues. 1) I wired the yellow and red onto my orange based off what I was reading. And the deck turns on even if the car is off. Should I have not wired both? Based off this wiring diagram: [ATTACH type="full" width="243px"]50865[/ATTACH] This is from the head unit: [ATTACH type="full"]50863[/ATTACH] 2) I have additional wires that aren't allocated in the image above. [ATTACH type="full" width="370px"]50866[/ATTACH] But I did find this link ([URL]https://pinoutguide.com/Car-Stereo-GMC-Opel-Chevrolet/Buick_2005-2008_Allure_La_pinout.shtml[/URL]) that has some additional information but I don't know what " Audio Common Signal (UE1)" or "Left Audio Signal (+) (UE1)" is. I'm guessing steering wheel controls? I haven't connected ALL of the ones from the head unit yet as it's still a work in progress but figured I'd start with some issues I'm seeing so far. Thanks for any suggestions, feedback you might have. [/QUOTE]
