The KC HiLiTES Add-On Wiring Harness solves exactly that problem. Quickly and easily add two more lights to an existing circuit so that they are operated by the same switch without overloading the existing wiring or having to run a completely new circuit.

All the connections are plug-and play and work perfectly with the KC #6315 Relay Harness Kit (not included). This kit does however, include a 40A relay without a switch.

        KC quality

        As with any of my KC purchases, quality is second to none. All connections are well made and makes adding additional Daylighters a snap.

      I have KC HiLights C3 3” flood lights. Would this be able to connect to the wire harness that came with them and be able to run the 4” round spot beam lights so all lights are controlled by one switch?

      I have KC Highlights C3 flood lights on my bumper. I would like to add 4”lzr round spot beam attached to windshield. I wanted to know if it was possible to somehow connect the 4” to the wiring of the flood lights so that the one switch inside cab would control both sets of lights.

      Can this be added onto the factory fog log harness of a '97 TJ?

      • This is designed to work with the KC relay harness. While it will work with the factory harness it will not be plug and play.
