My buttons look stock... for a boat. And I'm happy with the way it turned out.
Left to right: fuel injectors, clutch switch, DC/DC disable, MIMA.
I could imagine using the 0-3 switch for FE equipment. Maybe 0 is stock, stage 1 is clutch switch, stage 2 is MIMA, stage 3 also kills the fuel injectors, which isn't very useful, but it's a good anti-theft feature to have.
