Tailgate camera.

[Wayles Harrison]

I have noticed that the tailgate camera is plugged into a socket underneath the back bumper. How do you undo this connection and plug in a new camera in its place?

Are you talking about the reverse camera?  That's mounted next to the button to open the tailgate, not under it.  If you remove the black plastic tailgate liner on the tailgate you'll see the camera is actually plugged into something else inside of the tailgate.
