How to Wire LED Trailer Lights
- 1). Remove the old light assembly. Clean the mounting area. Install the LED light assembly mounting bracket.
- 2). Install the LED light assembly onto the bracket. This is a sealed unit and cannot be opened. It is waterproof and the diodes are not replaceable. They should never fail in the lifetime of the trailer. A tail light circuit will draw up to 20 amps. The LED assembly will draw less than 1/100 of an amp.
- 3). Splice the universal connector into the wiring harness. This connector is standardized throughout the industry. Install each lead according to the instructions: one for ground, one for the turn signal and one for the tail light. Use a test light if needed to determine which wires provide each function. In some cases, the ground is through the frame and is part of the mounting for the old light assembly. Make a lead wire to attach to the universal connector and ground it to the frame in a secure location.
- 4). Attach the universal connector to the new diode light fixtures. Test each function. Any circuits that are not working should be tested from the vehicle plug first, and work back to the lights. Check the vehicle fuses, and test each circuit with a test light.
