Hello SnglSrvngFrnd and welcome to the forum from N.E. Indiana!!! Looks like someone did some messing around back there for sure! I'm not sure if the Ford camera and sensors would work with an after market head unit. Mainly because of stock Ford connections. Good luck.

 

If its an XL it didn't come with a backup camera. That is an aftermarket camera, they are about $50 and work with aftermarket head units. The hole you drill for an aftermarket backup camera is almost or identical to the hole that the spare tire rod goes into. They probably had it placed in that hole. I drilled a hole on the opposite side of the spare tire hole to mount my camera so you can't tell it was never supposed to be there.

The reason why the trucks not going crazy is because you can turn the audible beeps off in the driver's console. Sometimes they annoy the hell out of me, and sometimes they're fantastic when in a tight parking lot. They are only for reverse. I believe when you put the truck into reverse a message will come up to turn them on or off.

 

 

Also, I don't see the alignment/retainer pieces that go into the bumper in your video.
