Trailer Wiring is as easy as inserting the trailer plug into your vehicle’s pre-rigged system. The following schematic shows typical schematic diagram of the 6 Way Trailer Wiring Diagram and Connectors Pinout. The 6-Way Trailer Wiring connectors allows 1 or 2 additional wiring and lighting functions as the basic hookup of the three lighting functions (running, turn, and brake). The ground and two extra pins are available to provide two additional functions, typically for electric brakes and 12 volt "hot" lead. In fact, most vehicles, especially those meant for towing, come prewired and ready to roll.
