76 Mercury 175, I want to install a kill switch but I'm not sure which wire to make or ground.

You will attach one side to black(ground) and other to orange (kill). Do not cut wires into but splice on to them.(solder or water tight scotchlock connector)

Re: Tether kill switch

There are three kinds of kill switches as well. Normally closed, normally open and one with terminals that allows wiring in either configuration. The type you need is for a magneto ignition which grounds the ignition to kill the engine so you need the normally closed. Sounds backwards but normally closed means the contacts are closed when the lanyard is pulled, not when it is installed.

Thank you. I looked at my wiring diagram but really couldn't figure out how the ignition switch was doing it.
