I have the same problem with my tailgater connection, the problem is a splitter located in the wiring and the tailgater needs power from the receiver to work and so the power will not flow thru a splitter. I located the sat. cable under the living room slide and spliced into this cable, this is where I connect my sat. cable for the TV in the living room, for the bedroom I connect to my sat cable comin in thru the storage compartment and up next to the water supply for the toilet. The people who designed this sat. wiring have never had to connect a TV.
