Coax ConnectionsHere is what mine looks like with the faceplate removed. You can see the TV connection and the button facing the camera. The white cable is coming from your roof antenna. The grey cable on the right front, going to the right, is the cable input from the outside. The grey cable in the back, going to the left, runs to a splitter where two orange cables go to the other interior connector and the outside connector. I'm guessing most manufacturers get pretty much the same thing on these kind of parts. Unless yours is more complicated.
