I used the grill lights from F150LEDs. Purchased the harness that runs inline with the corner marker lights. All plug and play. They are on any time that the corners are on. Easy install, high quality, crisp and bright, I really like them. Hope this helps.
I stripped the harness and isolated the wires for fog lights and was going to add them to the old harness. While striggling to remove the hard to reach clips in the center I found that the harness branches to even another component besides the servo that controls the lower shutters.
Maybe it...
I just ran into this problem tonight. I had everything apart before I noticed the pigtail for the shutters.
My 2024 XL has the 2.7, maybe that is why?
Would the local Ford parts department be able to help?
Thanks for all the info so far, I hope we can figure this out.
