Would like to get some help with the location(s) and function of the various toggle switches (bilges, wipers etc.) found on the panel in front of the throttle controls of a 1988 Gulfstream. There's quite a few switches, some work but would like to know what each toggle originally operated. The boats been repowered with twin Merc Fourstroke 150's mounted on a custom aluminum pod stretching from port to starboard. Giving her a new life as a West Coast guideboat in BC but need to identify the wiring and fabricate a new toggle switch panel. Any help would be great.
