What year is yours? Mine is a '12 and I have 3 of them vertically in my docking station. For some unknown reason, the top one goes to the rear bunkroom and the middle one goes to the main TV. The bottom one is Park Cable. However, on mine there is another dualconnection behind the main TV that has to be changed to get satellite to come through that connection. WHY?? I have no idea. But then have to change it back to get the park cable to come through that connector. Reminds me I need to go get a splitter and fix that so I can just slide the splitter instead of having to change the wires.
