Wire A Trailer

By | August 16, 2022



Hitching a trailer to your vehicle can help you expand your transportation capacity for large items, but wire the trailer incorrectly and you could be facing an inconvenient and dangerous breakdown. With the right supplies and a few easy steps, anyone can confidently wire a trailer.

To begin wiring your trailer, you will need a 4-way trailer wiring harness, which is available online or at any auto parts store. These contain a flat connector that has 4 wires, each with its own color. After attaching the wires to the trailer’s lighting system, you’ll need to connect the other end of the harness to your vehicle’s electrical system. Depending on the type of vehicle you have, the connections may vary slightly.

Next, you’ll want to ensure that your electrical connection and brake lights are working properly. To test them, you can ask a friend to stand behind the trailer while you put the lights into their different positions. If everything is working correctly, the trailer’s wiring is complete.

Finally, it’s important to secure the wiring connection against the elements. To do this, use electrical tape or waterproof tubing to encapsulate the connecting point. This will protect your wiring from short circuits, corrosion, and damage caused by road debris.

By following these basic steps, you can easily wire a trailer and hit the road with extra cargo in tow. Not only will this save you time and money, it will also give you the peace of mind knowing that you can rely on your trailer’s well-wired connection.
