Gonna try that now.Do you have a back up camera?I was just reading some other threads and people were saying to hook up the 2 wires off my camera to a power and ground not the reverse lights then hook up the rca off the camera to the brown rca off the d3? Would that work?I'll just find the power and ground in the trailer plug,hook my camera wires to it and the hook my rca up and it should work according to the other threads???Beats the heck out of me,I can turn a wrench just fine but wire strippers are a whole nuther ballgame for me,LOL!
