After getting rid of the supplied sound system I was looking over some of the cable TV system. There is a series of switches in the cabinet at the entrance door with all sorts of labels on each switch- but there are no instructions about what goes to where by switching each of them. Is there anyone can provide a clue of where to get this information? I want to take my Sat dish with me and I'll set it up on tripod out side- Can I use any of the wiring or do I just punch a hole through the wall of the RV?
