Using mirrors and by "fishing" the coax cables I finally located the splitter and checked it out. There is an electrical schematic in the forums for this app. From this splitter you can take individual control of the three outputs. I think Iggy was refering to Coax leading to the right slide in a 378. That run comes down the windshield pillar, aft in the fwd end and out a telecoping tube to the fwd end of the slide for the large TV. I'm also in a 2012 378.
That large space covers the entire width of the coach, behind and below the cabinets
