Morimoto Ford Super Duty (17-19) OEM LED Conversion Harness
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.
