That will be wiring added aftermarket, so online info will be scarce unless you can find somebody with that item or find a brand and model number to look up. tough unless you get lucky?
But what you may need is info on what it had as built. That can be helpful as a step toward building what you may want as there are tape markers put on when built to help ID the different coax and what/where to expect the other end!
You will need to check the serial number for the best info as there were two different builds in that year.
One way to get that serial number is on a label next to the driver's side. Look for serial number of the RV, not confused with the VIN which is the chassis!
The 7th digit of 1 or 2 is what the look for in this use but knowing for sure what you have is a big help if you need chassis part as the chassis and RV may be different years!

Once down to the correct RV, look to the bottom of the list for TV connections. Notice the ID on different setups? Different RV will have different setups of different equipment, so it may take some searching to find one which most matches what YOU have?
On that drawings, there are wire ID of tape wrapped near the ends. Those should match the blu, grn, red, colors on the drawings as a way to understand what you have!
Using the first set of drawing types and then the installation drawings which give the physical layout to expect, you can begin to sort what might have been there if not changed!
The problem with audio/video wiring is that people often change them!
I would guess it to be a real "hunt and peck" search to find what you have and figure out how you want to change it!
Good luck on the chase!
