2018+ Ford F150 Halogen to LED Conversion Instructions

Your new harness kit (one harness setup per side) should correspond with the vehicle plugs and the new headlight multi-pin plug.

Plugs to match up:

-Turn signal/parking plugs (one per side)
-4-Pin input plugs (one per side)
-Multi-Pin LED Headlight Plug (one per side, this plugs into the new LED headlight housing)

PLEASE NOTE: Be sure to TURN OFF your DRL (Daytime Running Lights) option on the dash board computer.

This kit requires an ECU re-calibration which can be done with FORSCAN –or–at any local Ford dealership that is willing to help. It’s a simple parameters switch on the ECU settings to disable warnings/errors/flickering.

If your LOW beams do not stay on, please ensure the DRL option is turned OFF on the dash computer selection.

PLEASE NOTE – on ANY of the charts referenced, the STOCK value may be different from yours. You are ONLY changing the number indicated – from a 1 to a 0 in most cases. On the 726-26-02 parameter, this is set to a ONE (1). 

Splicing / Fuse Tap:

A fuse tap for the installation of the DRL wires is optional. These are the LONG black wires coming off of each harness that NEED 12 volt SWITCHED power to illuminate the DRL BARS on the headlights when the vehicle unlocks and/or is being driven.

These wires can ALSO be run to a CONSTANT 12 volt power source that is controlled by a switch (you add), if you prefer to have the option of turning them off anytime you want.

Below is an image of an optional fuse tap that can be used.

Troubleshooting –

If your turn signals hyper blink on the DASH (but the actual headlight signal blinks normally) – please confirm all connections are secure and have no corrosion.
