Mystery Plug

We recently purchased a 2018 GT and it has two cables on the hitch. One has the standard 7-pin connector. The other is about the same weight, but has this plug on the front end. The dealer said "Oh, that's a special Ford plug. You'll need to find an adapter so you can plug it into a 4-pin connector before your rear camera will work.".

This didn't sound right to me, and I quickly found that the camera comes on fine when the running lights are on. Since the dealer was wrong about the camera, I'm not sure what the purpose of this cable is.

So - my questions:
1. Is this really Ford-specific?
2. Assuming it is for a Ford, and given that I'm not using a Ford TV, is there any reason NOT to remove this and reduce the clutter on my hitch?

Its for a Ford with trailer TPMS and a rear camera. It was put on by a prior owner. There is no reason you can't remove it.

This look like what it might be, but 100% sure

As CRH said it is for a Ford wired backup camera and wireless tpms system.

From that connector back the cable Y's. The shorter section of the Y (about 10 feet) goes to a receiver box for the wireless tpms, about the size of a cigarette pack, mounted somewhere near the front of the trailer, mine is under the battery box. The other branch of the Y is long enough to reach the back of the trailer for a wired backup camera.

I cut the camera branch off, wasn't needed with the wireless Airstream camera.

You can safely remove all of the cable unless there is a Ford TV in your near future.
