can someone guide me towards a color coded diagram of the ignition switch. i lost the key, cut the old switch out and wired in a 3 pole (off on start) switch. it starts and runs, but i gotta jump the black yellow wire to ground to get it to turn off. not sure what the other wires are for. i lost all my gauges too so im sure some of them need ground and/or power.


going off of memory, here is what i "figured out"

red wire = +12v from battery (40a trip breaker) (wired to "B" on switch)
there are 2 purple wires, to the coils? these need 12v to keep motor running (wired these to "ON" on new switch)
yellow/red - +12v TO starter (fused 30a in engine) (wired to START on switch)

black w/ yellow (seems this wire kills the engine when grounded, used it turn off)

Most of those a pretty generic and either "Push-to-choke" or not. Should be able to just google "Boat Ignition Switch" and find something that matches. Black w/yellow is usually Ground/Kill. Should be a solid black for the battery negative. Tach is usually gray.
