When I had a 2008 BH I had to cut and splice some coax.
The satellite wire that comes from the UDC did not go directly to the bedroom. It went into the belly, go split and came back up to the BR.
So, behind the basement wall I found the wire that came from the bedroom plug, (the white coax), cut it off and added an F-connector. Then used a barrel connector on that and ran a new piece of coax to the UDC. I removed the coax that was for the bedroom and connected this new one.
Here are a couple of pics that may help you understand what I am talking about.
Peace
Dave
