Ok thanks, Not sure which wire(s) I should use then. This set up was recommended in another thread. I tapped into the existing rear hitch harness and the wires are BRN for the Parking lights, Lite GRN for the back up lights, Dark GRN for the RT Turn signal, Yellow for the LT turn signal, Dark BLU for the electrical brakes, RED for battery and Black for ground. The connections I used utilizes the Dark Green and yellow wires for the turn signals and brake lights (which work when head lights are OFF) and the Brown wire for the running lights (when the headlights are ON).
