In theory to get this going at a setup, all you have to do is unplug the yellow cable composite video from the tv and into your y-splitter (see the yellow cable in the diagram). Some TVs will look dark when you split the video unpowered, but you can sometimes adjust the brightness up in the TV to compensate. Or maybe you could figure out a powered splitter, but this would further complicate the setup. I'd look into somehow battery-powering this RV splitter.
