Morimoto OEM LED Conversion Harness — Ford Super Duty (2017–2019)
Ford's factory LED headlight assembly does not plug straight into a Super Duty that left the line with H13 dual halogen lamps. This HD Relay Harness bridges the two, letting you run OEM LED headlights (H129K) on a 2017-2019 truck without complicated modifications. Low and high beam control stays where it belongs — on the factory switch.

What does this harness actually do?
It lets a 2017-2019 Ford Super Duty that came with H13 dual halogen headlights accept OEM LED headlights (H129K), handling the wiring differences between the two systems.
Does it fit my truck?
It is built for 2017-2019 Ford Super Duty trucks originally equipped with H13 dual halogen lamps. Trucks that already have factory LED headlights do not need it.
Is installation complicated?
No. It is a plug-and-play wiring kit designed to avoid complicated modifications.
Will my headlights flicker after the swap?
