C36 wiring
Congrats on your new boat.
The best way to find out where the wires go is to take off one of the light fixtures and follow the wires back to the electrical panel.
The best place to ask C36-specific questions is the C36 Association website, folks you should get to know. You can join the website and gain access to their forums. You should, even better, join their association, and gain over 20 years of valuable information that will save you hours and hours of reinventing the wheel.
