A killswitch for what? the motor? isn't that what the key is for....when you turn it backward that's a killswitch....
Humm there are a few : one like the races use on the back of the Race vehicle, the alarm cut off style that hook up to the starter or the steering column, then there is the one that hooks up to the battery "knob that trun a few turns then the battery off but looks like it hooked up and you can run a bye pass wire for the clock & alarm" .
