Hi...

That would be from the sat dome on the roof. The AUX outside connector come into the front where the gear is. The bad part, at least in our AUX connection, is it was pushed behind the false wall. So you should be all set as the one you mention should be from the dome.

However, be in known that you need to watch the same sat that the front tuner is watching as the dome can only point to one sat at a time. Not the same channel, but the same sat which will carry different channels. Your main receiver controls the dome movement and their is a special process for setting up the second receiver to be usable. So be sure to look at the instructions that came with the sat dome for instructions on this.
