Product Details

Modernize: Designed to adapt the 2017+ Ford F250 OEM LED headlights onto trucks that came standard with base H13 Dual Halogen headlamps, this wiring harness kit will allow you to upgrade to the most modern Super Duty look without cutting, splicing, or modifying anything on the truck's factory harness.

Plug n Play: This wiring harness kit is a seamless solution to keep your low and high beams under control on the new OEM LED lights using the original controls inside the cabin. The outputs will plug directly into the multi-pin connector on the back of each headlight from Ford.

Advanced: The unique Morimoto relay harness is designed to retain full function of the OEM headlight just like it came from the factory. No hiccups, no flickering, no problem!

OEM Grade: Aside from being ahead of the game from a technical standpoint, the Morimoto HD relay harness is also a work of art. With its wiring protected by abrasion resistant Techflex mesh sleeving and its extruded aluminum relay shell that's been anodized and laser engraved - the MotoControl Harness will look factory fresh under the hood!

2018 Ford F250 XLT with OEM stock halogen headlights. I bought this harness to convert to a set of OEM LEDS I purchased off of a 2019 F450 DRW. This harness worked perfectly and the install was easy. I'd say it took me about 2 hours bc I took my time as to not damage anything. I was even more excited when I set my headlights to AUTO and they still worked contrary to the description of this harness. Meaning when set to auto they come on when it starts to get dark. Not the cheapest harness but made the conversion a breeze. I didn't have to use Forscan to change any settings either. Thanks.
