Putting an "idiot light" in series between the sensor terminal and the ignition switch will prevent feedback to the ignition system and avoid the run-on problem on shutdown. Use a regular 2-wire incandescent indicator bulb, not an LED. The bulb filament limits the current backflow so there's not enough to power the ignition system.
