What is Trailer Wiring?
Trailer wiring is a system of wires and connectors that allow your truck to communicate with the trailer. It includes a plug on the back of your vehicle that connects to the trailer’s electrical system. This system allows you to power the trailer’s lights, brakes, and other components.
What are the Components of Trailer Wiring?
Trailer wiring typically includes four components: a plug, a socket, a converter, and wiring harnesses. The plug is located on the back of your truck, and the socket is located on the trailer. The converter converts the electrical signals from the truck to the trailer, and the wiring harnesses connect everything together.
