Kill switch Johnson 6HP 1968 Model CD-25C

[cocktail racer]

I need to place a kill switch on this motor due to rules from the cocktail class racing association. How do I do that?

Find the wiring diagram for a 68 model 40 hp.--------Then install the 2 wires through the ignition magneto plate.-----Hook them up to the condenser / coil wires--------To stop the motor those 2 wires are connected by your kill switch.
