dclarke 4,011 #1 Posted August 8, 2019 I have an '81 C175-8 that now has a Kohler Magnum 18 with electronic ignition in it instead of points and condenser that came in the original engine. Can anyone tell me how to wire this engine and which ignition switch to use. The ignition switch that's in it now is different from the original plus a toggle switch has been added to engage the starter and the wiring harness is a disaster. I'd like to build a new wire harness and eliminate the toggle switch, just not sure which ignition switch I need or how to wire the engine. Thanks. Share this post Link to post Share on other sites
