There is info online to help us sort these questions.
Several of them may help you find what you need or ID what you have found as they use a color code on the coax.
This is a semi-generic chart showing how the different coax may be installed, depending on what options your specific RV has.

Looking at what you have in equipment and matching it to one of the diagrams can be a start to knowing where the other end of a coax should be found. But one of the easy points to miss is the color code shown for each coax!
Note the designations of blu, grn, red, on various drawings? That should be enough to ID the various coax in the RV!
That drawing does nothing for location of those parts, so this drawing is for your specific RV and may be more help on actual locations of things as it is the install drawing.

You will still have to sort out which options YOUR RV was ordered with, like 68X or 68T as a way to avoid confusion but looking at the colors, you will find they should be consistent and match both the colors shown on the other drawing as well as what you find on your coax.

See if that clears some confusion and shout back if other questions!
Good luck on the chase!
