This is a great idea. I'll try something like on the next car. I think 
the best security results from engine turnover-its up to the thief to 
waste time guessing if there's a fuel or spark disable or just a crappy 
car that won't start-if it runs for bit and dies, all the better. Combine 
that with a handmade one of a kind reed or thyrister in your place of 
choice and you've got peace of mind. This gives nearly the level of  
security of "the plug" ($15.00 vs.$200.00).
