Our Rear Accessory Electrical Harness allows for easy wiring of any LED lights, brake light, license plate light, or powered LED lighted whip. Simply unplug the connector at the back of the factory taillight, plug the harness into place and then reattach clips. One minute install, and no cutting required means it’s a true plug and play accessory! A single Rear Accessory Electrical Harness can be plugged into each taillight for additional accessories. This is recommended for low current lights or to trigger a relay for larger high power lights. If circuit is overloaded it could cause the fuse to blow or damage the OEM wiring. Warning! Do not overload the vehicles electrical system.
