EDIT 11/13/24: I was told that you can just perform the forscan changes to get the lights to work. It apparently works for some just on the Lin line, but if you want it wired like a lariat, follow my wiring steps. But it doesn’t hurt to check just forscan changes first!!!!
For those curious, yes, you can make Lariat headlights work on an XL/XLT. You may or may not have seen my many messages and posts trying to gather as much data as possible. The taillights are plug and play (at least on XLT) and the signature taillight lighting works without any modifications or changes, since it’s just powered by the parking lights, and the upper DRL’s on the lariat require you to move one wire for that circuit from a splice with the low beam to its own circuit. On lower models ford does put the wire for the lariat DRL’s in the harness from BCM to headlamp but for some reason splices it to the low beam circuit roughly 6-10 inches from the headlight harness. It is the only splice, and the thinner (20 gauge?) wire is for the DRL. The PN for the wire/pin that will be needed to install into the headlight connector is DU2Z-14474-DA (x2). I cut the wire before the splice, soldered on the pin/wire I purchased, and put it in the connector for the headlight. On XL/XLT, the DRL pin you wired in will do into the connector where the white spacer is currently installed.
Here are pics of how I did the wiring, the second shrink tubing you see is my wiring with the new pin, the brown/blue is the original where you will have to cut the small wire:
Just de-pin the spacer, there are videos on YouTube on how to do that so I’d refer you there for assistance.
In order to make the headlamp DRL’s work properly, there is also some work in forscan that has to be made in the BCM. See the screenshot chart below on what to change in the AS-BUILT. Please, make a backup of your bcm before any changes so if something happens you can easily, and quickly, fix it.
Here is the code to change:
Note: you may or may not have to perform a LIN new module initialization to get the DRL’s to work. I had to do that, so you make have to as well.
You may also have two codes trigger with the headlights in the bcm: B124A, and B124B for daytime running lights circuit open/short codes. They don’t affect usability, but I am saying this so that this project is completely transparent for anyone who wants to try it.
My goal here was to have an XLT FX4 but add the BAP accents on the exterior, plus the lariat signature lighting. Ford, in their infinite wisdom, doesn’t let you order BAP and FX4, I’m assuming due to wheel choices. So, I decided to do it myself on the outside, but go a step further and make the headlights LARIAT style. Was it more expensive? Yeah. Was it worth it? To me, yes it was. This truck is now exactly the way I want it.
Part numbers of HeadLamp Assemblies (not sure which is left and right:
- PZ6Z-13008-B
- PZ6Z-13008-D
With that being said, it is possible, but not the easiest nor cheap at $1100-1500 per headlamp assembly and around $400 per taillamp assembly. Hope this helps someone who is trying to do this!
Credit to @EONR24 for the help! The headlights work just like it was a lariat, with the upper portion dim at night, and super bright as DRL’s!

I would have got a lariat if they offered it in hybrid, Canadian problems. Finally they did for 23+
