i'm working to re-wire mine now. i had a new panel built, cut a new hole in the console (starboard side) for a new access door/hatch, and am slow progressing to fit stuff before i start pulling out the old wiring.
i'll post a couple photos of my project.
the panel built for me. (i made the wood frame)

the problem is that there is only 4" clear between the console side and the wires coming from below. there's only 5" at the top because of the throttle/shifter cables. So i had to cut the dropin box and add a back.





i still have to figure out how to run all the wires in and out.
here's my wiring diagram.

you can run multiple GPS's off one switch with terminals if needed.
