Just purchased a Pioneer and was told the backup camera mount was prewired for a Furrion. It was a matter of just plugging into the female line already there behind the plate. I decided to purchase the Furrion and install myself, but once removing the plate discovered there was no ready to plug in female line. The wiring that was behind the plate were a set of double wires with insulated caps on each, 2 solid white and 2 white/green. The wiring on the camera is a black and red with red being positive. My problem is I don’t know which to attach the red wire to. Anybody know the answer?
