Relay and Neutral safety switch Question.

Anyone who knows anything at all about "boosting" cars knows how to jumper the starter / starter relay. I believe this is false hope

"Better ways?"

You use an electric fuel pump? Then a switch in the pump relay

You have a tach, or even if you don't, put in a switch that GROUNDS the coil NEG line

If you do NOT have an electric pump find and install a fuel shutoff. The thief starts the car "it runs great" just long enough to get out of the parking space, and then.............
