I'm Going To Guess....
that they go under the anchor windlass box in the V-Berth to one side or another and then to the switch panel. Was asking myself the same question when I thought I'd have to re-route a new run, and that's the conclusion I came to, but I was lucky enough not to have to test it. Good luck, maybe someone on the board has experience with it. There is a wiring diagram in the manual; not sure it will be a help tho. Rick D.
