Ok so I’ve got everything figured out except the magneto. Does one of them connect to a 12v or hot wire and one a ground or both groundSince you or us have no idea what wires are what because of lame wiring practices, you have to be the sleuth in this. Here is picture of what the ignition switch pins should be. Keep in mind the wire colors are for a Mercury outboard but these switches are very universal. The pins are identified on the diagram. You need to figure out what wires come from the engine.
