just get an alarm bud, so much less hassle, but if ur set on kill switches then a carbied motor is no different than efi apart from the electric fuel pump, but alot of carbied motors have electric fuel pumps any ways. first off chuck one inbetween the key and the starter solinoid(or relay), then throw one in between ur key and the coil positive, if ur carb has a anti-dieseling solinoid throw one in there to. 3 should be heaps, if u wanna go overboard hook up a kill button to your handbrake button so u have to hold the button down to crank the engine

:D:D switch wise just get small toggle switches maybe even with covers so u dont know them and shut the car off while driving. slap them under seats or even in ur drivers side (or passenger side) air vent so u have to open the vent and poke ur finger through the vents to switch it

or a water proof switch under ur gaurd, just pretend to drop ur keys every time u get in and out of the car
