If you have questions about where all of the RG6, speaker wires, antenna wires, sat in wires, etc., really go, call Jayco and ask them to email you a wiring diagram. I did and it made figuring out how to hook things up so easy. My dealer didn't have this diagram, but Jayco emailed to me in a couple of minutes of my phone call.
