bconnaway Posted September 21, 2011 Report Share Posted September 21, 2011 So, I got a backup camera for my truck and was trying to install it tonight and got stuck when I tried to wire it up to my head unit. The problem I am having is figuring out what wire coming out of the head unit is the wire that triggers it to turn onto the camera when I shift into reverse. When it was installed, they removed the tag (if it had one) that told which was the reverse wire. Every search on google I try always tells what wire it needs to get hooked up to, not what wire it is. The only place I did see mention of a wire coming from the head unit was a violet and white wire, which mine doesn't have... Please help! Quote Link to post Share on other sites
VBLUE42 Posted September 21, 2011 Report Share Posted September 21, 2011 Its violete with a white strip and its detailed in the install manual. If yours doesn't have it you need to have a conversation with your installer. Quote Link to post Share on other sites
bconnaway Posted September 21, 2011 Author Report Share Posted September 21, 2011 Is it on the main power harness or the AV harness? I have a purple wire on the power harness, but it is connected to the radio harness and comes out as an orange w/ red wire. I also have a purple w/ black wire? Also, my install manual is in Houston and I'm in Austin right now. Do you know of an online version? I've only found the user manual. Quote Link to post Share on other sites
bconnaway Posted September 21, 2011 Author Report Share Posted September 21, 2011 I just realized there is an open hole between the amp signal wire and the parking brake signal wire on the power harness. Is there supposed to be a wire there? Quote Link to post Share on other sites
bconnaway Posted September 21, 2011 Author Report Share Posted September 21, 2011 Got it working. That hole was where the wire was supposed to be. Ran a wire in there, taped everything up very well and it worked perfectly. Not sure why it wasn't there in the first place... Quote Link to post Share on other sites
1loudls Posted September 23, 2011 Report Share Posted September 23, 2011 Not sure why it wasn't there in the first place... because your installer either yanked it out, or used the wrong harness. i really not a fan of either option! also for the record, the solid violet wire is positive right rear audio out, and the violet/black is negative.
