Have design for auto anti-theft fuel shutoff

Hello,
New member here. Just used your help to locate fuel pump wiring. will offer in return to anyone
my circuit for an automatic fuel shutdown after several minutes of not being disabled by your secret button. It all works, but I didn't know what wire to break.
To anyone interested.
Drawbacks thus far. It can't be disabled until the timer times out (any delay you wish). Also, since it 'arms' each time you select 'drive' that means you have to disable each time ( buzzer reminds me). The idea was to let the car-jacker get away, but only for a few minutes drive time.

Welcome to tw! Nice work coming in and actually adding something to the community instead of asking about tire sizes!
