You won't find any instructions. I installed the Travler on my Voltage for Directv and use the Geni system. The cable system was bypassed and HDMI cables are used, instead, to connect the wireless mini-Genies to the TV's.
If you are intent on using the trailer's cable system you'll, most likely, find that the cable splitters are cable ready but not satellite ready. That's what I found on my trailer so they (two of them) were upgraded. Still, we had interference and snow issues, which is why I chose to go the Wireless Genie route. We get crystal clear HD TV with the Genies.
