This answers Tom's question; I'm getting closer. The mount won't be difficult and I have a 60' fish so the cable shouldn't be too hard. Fitting the RJ-45 through the grommet looks tight. Reading the assorted manuals, I see that I need 12 v. at the bottom of the mast. Todd, what's the difference between the red and yellow? Sounds like red is the real power, but the yellow is the signal to turn on? Probably can turn on together, but yet another wire to run.

Cover may come off soon; easier to walk around that way. Windlass runs; just never used in "anger" since was no sailing last summer.
