This plug-and-play relay harness perfectly connects KC lights or other aftermarket lights to your Jeep's OEM headlight functions.

Designed specifically for 2018+ Jeep JL/JT models, this Headlight Auxiliary Light Adaptor serves as a trigger relay to integrate additional lighting with your Jeep's three headlight modes. Whether you're using your Low Beams, High Beams, or Halo (for models with Mopar LED Headlights), this adaptor makes adding LED lights easy. No need to splice wires or modify your OEM harness—it's a water-tight, heat-resistant, DIY solution that saves you time and effort. Just follow the simple step-by-step installation guide and hit the trails faster!

Features:
  • Engineered for Jeep JL (2018+) and JT (2020+)
  • Easy plug-and-play installation
  • Water and heat-resistant
  • Relay Trigger for:
    • High Beams
    • Low Beams
    • Halo Light (if equipped with Mopar LED Headlights)
What’s Included:
  • Wiring harness only
Fitment:
  • Jeep Wrangler JL / JLU Models (2018+)
  • Jeep Gladiator JT Models (2020+)
Recommended Light Pairing:
For optimal trail lighting, pair this harness with a set of FLEX ERA® 4 or Gravity® Titan™ lights. When connected to your High-Beam relay, you'll enjoy improved visibility and a better overall lighting experience. Or, pair it with the FLEX ERA® Fog Light Kit to take advantage of fog and off-road modes, all controlled through your OEM light switches. With this harness, upgrading your Jeep’s lighting is hassle-free, without the need for extra expensive switch units.

Yeah I was thinking $50 would be the max I'd pay for this.

Will this harness work for my needs, I swapped my halogen headlights on my 21 JLURD to a set of LED takeoffs from a 20’ sport and I can’t get the halos to function as the DRLS on the passenger side, I’ve tried everything in JScan, still no luck

Hello @NyRey87

Sorry for the delay, If you upgrade from the halogen to the factory LEDs, additional wiring is needed and programming to get the halo to work, Once the halo works and is being powered you can connect this wiring to the halo function.

You can use this wiring in the link below

It would be Part A

Thank you for the response. It seems as tho Mopar 68347117AB Wiring-Jumper Harness has been discontinued

I had the right side Halo working through JScan but couldn’t get the left one working. These are the connectors for the left side. Any one know where I can source that Jumper Wiring Harness?
