New Member 1st post. Did a Search couldn't find relevant post. I have a 93 maxima gxe that I put a hitch on for a small trailer. Trying to hook up a 4-way flat connector to the taillights but running into problems. Wiring diagram for connector says:White: GroundBrown: TaillightsYellow: Left turn and stopGreen: Right turn and stopAccording to the wiring at the taillights I have separate wires for taillights and stop on either side. Do I need one of those Modulator thingys?
