1992 Acord - Kill Switch ideas ?
 

I was recently surprised to learn that early 90's Accords are near the
top of the "most stolen" list in many states.

I'd like to add a kill switch and am seeking opinions on what
circuit/device is easiest to neutralize? The fuel pump seems most
likely, and accessing it shouldn't be too dificult. It's a 5 speed, so
hacking the starter solenoid, the first idea to come to mind, isn't a
fool proof solution. Any other cantidates?

Car is a 92 Accord wagon.

Thanks
