Finding reverse wire
Installing a Pioneer AVIC-Z2, and was trying to hook up the reverse wire . Ran it to the trunk ( according to instructions )but the wires for the tail lights are all bundled and do not match the colors going to the back up light.
Which one is it???
or is there another place I can hook this up to?

Mine was a yellow / white wire in the trunk. There was one in that color combo going to each tail light. The wire goes from 0V to 12V when the car is shifted into reverse.

I'm powering mine thru a switched 12V source. That way I can view the rear cam anytime I want (good for burnouts ).

the Z2 has two modes, one is when you put it in reverse it auto switches to full screen or rear view mode which can be displayed at all time as full screen or split screen.

The easiest way is to simply chase down the actual plug of one of the reverse lamps, and splice onto that one. Either wire should do, although you really want to understand that if the bulb burns out, the camera may not switch on. If you took a test lamp or multimeter (properly switched to 20V DC (likely) ), grounded to the chassis, NOT the other wire, and took the bulb out, you can find the exact wire fairly easily, 'cause only one will be 'on', in reverse, and the other won't. Just turn the car on, but not running, parking brake on, stick it in reverse, and go check the wires.
There is also a wire for a switch in the gear shift. You can chase that one down, I'd think that'd be pretty easy, overall, because you'd just look for the reverse switch, and ensure which is on when the car's in reverse. Same trick as above for verification.
This is true for *any* Mustang, or car, really. Either will accomplish the trick, it just depends on which makes sense for your situation.
Shop manuals will point it out directly in the wiring diagrams, so buying/finding one might be prudent. Your library may even have the thing available, so check it out, if you don't want to buy one. But I'm sure it's on the internet *somewhere*...
Hope that helps!

I used the wire powering the back up lamp in the trunk to power the camera - but I really like the idea of adding a switch so I can turn the camera on whenever I feel like it. That will probably require 2 diodes so there is no backfeed. I tried a wireless backup cam system but it seemed to be a little flakey and often picked up signals from elsewhere (other cars perhaps) so I ran a proper wire with with RCA connectors and got a wired monitor that actually takes a signal from the rear cam. That worked much better and the quality of the video is far better too.
