Can you describe the wire, what if any connector it has and whether it is a single wire?

It could be the input/trigger signal wire to tell your HU that the car is in reverse and in that case you would connect to the reversing lights or the appropriate wire on the AV harness. What year 370z do you have? I can post some pictures to show you where to connect.

Or it could be the video in where you actually plug the camera in and in that case it will typically be an RCA connector.

Interesting how every post of yours (whatever the subject) always contains a link to the same company. Do you work for that company or are you just being paid to post links to them?

It's just a purple wire that comes from the HU adapter that says 'rear view cam' no connector on the end. I've added some cable to be able to bring it to the rear of the car if need be, I just didn't know if it sends the power to the cam, or if it is the reverse tap, which is what I'm guessing it is.

I have a 2010.

just wanted to make a note about the "orange" wire BIG speaks of. When wiring my HU and Backup camera. I ran a wire with the video wire for the camera up to the headunit, connected both the wire and backup camera power wire to the "orange" wire on the harness in the trunk on the left.

Im not sure what the harness does, but there are 3 orange wires. I used the first one(one on the end of the harness). everything works great!

You should not of garbed power for the camera from that wire, but I guess you can in a pinch. You should of attached the red wire to either the red wire of your head unit wiring harness or of the 12 volt outlet.

The orange wire is to tell the head unit to show the rear camera input. yes there are 3 orange wires in the harness however only one will only show power when you put the car in reverse.

Slightly OT, but can someone tell me where the stock back up camera lens that comes with the Nav is located? I can't find it in any pics (and don't get my car for a week). I know some of them are close to the license plate frame and I just want to make sure the frame I'm looking at won't interfere.

Ok, so the purple wire from my HU is the pick up from the car saying it's in reverse. So that's the one I need to tap in the rear harness with. The camera will get 12v power from somewhere back there, I just don't know where, then use an RCA for the video input to the HU.

I'm gonna order it today, it comes with it's own drill bit for the bumper, just have to figure out where. I'm thinking that little square piece above the rear fog light.

Big - That piece, have you mounted a cam there before? Do you know how to remove it to do so if you have a DIY or a few pics would be graciously welcomed. :tiphat:
