I have a 2006 LX, I am currently trying to hook up my original screen/radio/ac controls after having an aftermarket "Tesla Style" screen. Everything works as it should thankfully, except for the reverse camera. I have no idea what I'm doing. I removed the old harness and installed the OEM, all the plugs are there for the OEM units. I see some AV cables left over and a brown 8 pin plug coming from behind the AC vent, with nowhere for it to go. I can't find a wiring diagram online or what an OEM harness even looks like. There are millions of aftermarket installs but I need OEM. Can anyone assist?
