Switch #6 (up) -> Bilge Pos
And of course, Bat Neg to Bilge Neg.
Ignoring fusing, bilge lights, etc.
That seems right to me too. The Neg. (Terminal-7) on the switch is likely because it's a lighted switch.
Looks like a Double Pole - Double Through (DPDT) lighted switch. You'd only need to use one side of it for your application. Terminals 1,2, and 3 would not be used; unless the switch needs power (+, Pos) on terminal-2 to make the light work
in the switch. There should be a circuit breaker or fuse somewhere in the circuit between the battery
and terminal-5 of the switch.
