Guess I need a little more info: Are you trying to hookup to a Sat Dish on top of the RW, or is this a post mounted Dish at your site?
As for the connections in the utility bay, one goes to the port in the ceiling in the cabinet just to the left of the bedroom TV, the second one goes to the wall mounted port that's behind the living room TV. At least that's how it is on ours. The Orange cables should be coming from the ports on the Roof of the RW between the two ACs, where a roof mounted dish generally goes. I had to use a meter and buzz out the lines to know where to hook our system up.
