Your favorite body shop may look at it and tell you what it is. Ours did so for spots on the hood of a brand new car we bought in 2023. Determined mfg defect. Replaced hood under warranty.
2022 lariat 502A, 5.0L. Recall. Service picked up my truck, did the recall, and returned it to me same day. There are also two other recalls, wiper motor and rear axle harness. They did those in my driveway on another day.
Wiring is there. One of the tailgate connectors has an empty pin for it. Need a reed/contactor/magnetic switch and Forscan to enable it. It’s on the interweb somewhere with a video and pics.
