I am replacing the stereo in my 2012 T&C with an aftermarket one and I cannot get the backup camera to activate because I do not know which wire to connect. The aftermarket stereo has an Orange wire for activating the camera but so far none of the wires left over in my harness get power only in reverse.

Can anyone either tell me which wire to use or point me in the right direction to find the proper wiring diagram that shows it?

TIA
Larry
