Did a look and found some info but it is likely you will need to check the drawing for full info but I did a couple snips to highlight what I see as needed---but more info may be good, so take a look at this drawing:
Sheet 3 and 4 seem to be what might help?
Winnebago drawings often give a point like "detail CC" and then if you find that detail on the chart it gives a detail view. I have marked three points using different colors and cut out a lot of the parts, I didn't see needed for this as a way to make it less difficult to see through the chaff!
Important point to know may be how the coax should be marked with a band of tape to ID by matching colors at each end?
Click these pictures for better view but check the full drawings for the total plan?
See if that helps.
