The TV wiring is definitely confusing... Nothing is labelled and there are a lot of potential combinations to try to get right. I took mine apart and mapped it all out to simplify.
I made up a laminated label for the outside connection to mark which was cable input (on the left on mine) and which was the aux or satellite input (on the right on mine). The actual paper base came from the attached word doc file, just printed and went snip snip.
On mine I found that the outside aux/sat connection ran into a splitter to feed one outlet in the bedroom and an outlet on the Winegard plate. If you want to use this you will need to shift the TV cable inside over.
The cable input went into the Winegard amplifier to switch in when the antenna amplifier is turned off. It will feed out of the amplifier normally to feed the regular TV port on the Winegard plate and a splitter feeding an outlet in the bedroom and the outlet on the side of the TT.
This is all shown on the wiring diagram in the attached word doc.
There is some chance yours may be wired up like my 2015 Rockwood 2604WS
