I just bought a boat without an ignition switch and it has a Johnson 115 outboard. I bought an 6 terminal ignition switch with M,M,C,A,I,B,S lettering. But I have a Purple, Purple/white, red/purple, black, black/yellow, white, tan, and grey. I have been trying for longer than I want to admit to get this connected right. (the boat is a 1966 fiberglass) what color goes to what terminal?
