I just bought my first boat, a 1992 procraft 200 combo. I have been unable to find any information about the various switches and or electrical wiring diagrams for it. For the switches, the one that I am most interested in, is the switch down at floor level on the right side by the driver that has a square that is solid and a square that is just an empty box. any help you guys could give would be awesome. I was also wanting to try and find some wiring diagrams, as I am going to change it over from a 12v trolling motor to a 24v system.
