I’ve upgraded my 3.0 radio to a Modern double din. Part of this was to add a backup camera. I need to connect the “signal trigger” wire to my backup lights. I don’t know which wire to tap into. Can someone help me out?
If the head unit just needs a 12v signal to enable the video, you could tap into the reverse light by running a long cable all the way back to the tail light. Other wise, you would need a CAN bus adapter to get the appropriate signals.
