Have the MicroLite 21 FBRS. How do I use the TV outside. I know to remove and hang on the outside wall mount but where/how to wire cable and electricity? Do I need to remove the wires inside the cabin and bring outside? I have an electrical outlet outside below the wall mount so I assume that's where you plug the TV in. The only other connection outside is a fitting for connecting the incoming cable when supplied by the campground. How does the DVD player inside the cabin get connected to the TV outside? I'm confused. The salesman made everything seem so easy. Please help.
