Trailer Wiring
Trailer wiring harnesses connect your trailer’s electrical system to the tow vehicle. These harnesses transmit signals that control lights, brakes, and other powered trailer components.
Common wiring harness types include:
• 4-way flat connectors
• 5-way flat connectors
• 6-way round connectors
• 7-way RV blade connectors
Choosing the correct wiring harness ensures proper electrical communication between the vehicle and trailer.
