kill switch

I found the starter relay for a manual transmission car at the local junkyard. I ran a wire from the ground terminal to the cigar lighter center connection. Car will not start unless the cigar lighter is pushed in. At a car show I just pop the lighter in my pocket.

Frankly, this is easy to bypass and on a 69/ earlier car, the thief may never know the difference. Without a hood lock, I could hot wire my old 69 RR faster than I could dig the keys out of my pocket, unlock the door and start it.

A clip lead from the starter relay battery terminal to the ballast resistor and "any piece of metal" to jam in the starter relay is all you need.
