I have a 2012 Escape, didn't come with an installed rearview camera. I am attempting to install an after market wireless unit. But, I cannot find a switched power source in the wiring on the rear liftgate. I have found 3 or 4 "hot" sources, in some of the plugs (hatch release, window release,etc) but all of them drop off to about 3V when I test the connection for the camera, which is obviously, very low power.


Any help or suggestions?
