This harness has an update from the non -1, they added the key on wire in to the light hanress so you do not have to hook up the controller accesory wire in the control harness in the new version.
This is for the New 2020-2022 Fords with Quad H13 headlights. This is just the light harness, you will still need a module and the rest of the harness if you dont already have that. This kit gives you light harness 74972-1 / 74971-1 and 11 pin harness 26357. This has the built in soft start relays 69932-1. This is a 16 pin plug and will interface right into the truck harness no longer needing to plug into each headlight.
* If you have a 2017-19 Ford with the Quad H13 lights and want to change it over to the 2020+ trucks you could use kit 74039.
