Wiring in a backup camera - which wire is reverse?

[72Blazerod]

Hi guys,

I was just wondering if anybody knows which wire is the reverse wire at the back of the box for a 2006 GMC 3/4T Crew cab 4X4? I want to wire in a backup camera, and need to tap into the reverse wire.

Thanks,

Rod

RodI do not know, however a pictorial of the install would be nice, if you have the time. I'd like to see the screen and the other gadgets.

The center pin on the trailer plug is the backup lights.
