Ghost

I'm hooking up an aftermarket wireless back up camera system so I want to power the rear and front wireless modules from the reverse light power wires in front and rear. I found the reverse light power wire easily in the rear hatch by looking at the taillight (it's cream coloured on drivers side of my 2011 R/T) but I'm looking for somewhere in the front dash area to wire the wireless module that attaches to my reverse camera screen (Garmin GPS unit). I currently have it powered by hooking into the fusebox under the glovebox, I used fuse that says RR Camera hoping that would be it but that fuse has constant power so leaves my GPS showing the B/U camera even Journey is not in reverse. Looking for the wiring diagram or if anyone knows what wire I can tap into for the reverse lights up front - Or anyone know if there is a wire under the shifter bezel that has power when in reverse only? Thanks for any help?

anyone know which wire to tap "Hot" into for the rear reverse lights on the 2011 Journey. I have the back panel off and there seems to be 4 wires going to each light assembly (2 x black/blue and 2 x yellow/red). Trying to figure out which one to tap into for the reverse light power?
