Re: Ignition swith
hmm, if you can figure out what brand/model the aftermarket switch is then you could look up a diagram online. Failing that if the wiring harness is standard from the engine side you should be able to cross reference the wire terminals. Replacement Omc/Johnson/Rude switches are pretty cheap at boating supply stores. You might try in the johnson/evinrude engine forum and get better results.
