Clever anit-theft switches

Wire a push-button in series w/ the yellow wire from key switch to engine bay. You must push it as you turn key to "crank". Of course, anyone smart can jumper under the hood - BAT+ to ballast and touch 12 V to "start" on starter relay. You could wire a switch in series w/ the NSS to stop the later, though they could still do the "screwdriver to starter" trick. With EFI and/or an electric fuel pump, you have more options. I would like to take the time to wire a coil to give a thief a big shock. My 69 Dart was stolen in front of my house in 1994 and the license plate found on a stolen Jetta 7 yrs later in a redneck county. Car was never found, but the police don't really look. I did once do the "nails in plywood board, facing up" like a Charles Bronson movie when I suspected someone was jumping over my fence at night in Atlanta, but it saw no action.
