reverse light wire for rear view camera... So I'm looking at the instructions for installing a rear view camera to my Pioneer headunit. Everything seems pretty straight forward, attach ground, attach 12v power, attach RCA cable from camera to back of head unit....but I don't know where to tap for the REVERSE LIGHT.
There is a violet/white wire on my headunit's wiring harness. This wire is supposed to splice into the reverse light. This way whenever the car is in reverse gear, the head unit will automatically display the rear view camera.
Obviously this violet/white wire is not long enough to go from my headunit all the way back to the reverse light, so there is probably a wire somewhere behind the dash to tap into. How can I identify this wire and where is it??
I have attached the page from the instruction manual for clarification. Thanks!

The easiest way is to run the wire back to the backup lights. The light green wire that feeds the backup lights comes from the park/neutral switch on an automatic or the backup lamp switch on a stick. Both are switches mounted to the transmission under the car so they aren't convenient places to connect wiring.
Another option is to use your own switch connected to any 12V power source. You would have to switch it manually when backing up but it gives you the option to turn on the camera at any time - even when not in reverse.

I've been researching all this stuff to see how much effort it would take. It seems like a CCD lens is far superior to a CMOS lens (most cheap eBay cameras).
