Not exactly sure what you are asking.
The Wally obviously must have power (120 VAC connection).
Then you need coax to the X2 from the Wally. Try not to run the connection through any splitters. The best connection is direct from the Wally to the X2 dish.
We've had luck with ours with 100ft of coax cable.
Maybe in your case run a long HDMI cable from the Wally to the TV.
Hope this helps.
