Connecting 4-wire trailer lights can be a tricky task, but it doesn't have to be. With the right tools and a little knowledge, anyone can quickly and easily make every connection necessary for their trailer lights.
The first thing you need is the right wiring, which includes a 4-way connector. This connector will allow you to link the lights on the trailer with the lights on the vehicle. After that, you'll need a roll of 16-gauge wires for connecting each light and one 12-gauge wire for the tailgate's power. You'll also need some electrical tape or shrink wrap to insulate your wiring and keep it safe.
Next, using a voltage tester, ensure all the lights are off and then start attaching the wires to the lights. The brown wire should be connected to the ground pin on each light. Then attach the green wire to the left turn/brake pin, the yellow wire to the right turn/brake pin, and the white wire to the reverse pin on each light. Once you've done this, take the 12-gauge power wire and attach it to the positive post on the battery or the power inlet. Finally, use some electrical tape or shrink wrap to seal all your wiring connections and ensure no moisture or dirt can get in.
By following these steps, you can easily connect trailer lights safely and securely. Once everything is connected and protected, you're ready to hit the road and show off your well-lit trailer. Just remember to always double-check your connections before hitting the road to make sure they are secure and properly insulated.
