4 Pin, 4 Way Trailer Connector

White = Ground

Brown = Tail lights

Yellow = Left turn

Green = Right turn

If you are trying to wire a car/truck that has separate turn and brake lights to a trailer where they are one piece you are going to need a Converter. These use diodes to change the currents to the tail lights. They are sold at most parts stores for around 10-20 bucks.
