RE: How do I install this kill switch?
If you notice that little plate that says OFF and ON can be removed and turned around.......
When the switch is ON it is making contact between terminals(conducting) thereby grounding the ignition and killing the engine. So, if you turn that little plate around to where it says OFF when the engine is killed,,,,,,,, you will have a neat way to tell whether you are in the OFF or RUN mode.
