What I personally would like is to use an alarm system with a starter kill and maybe an auxiliary circuit that activates if the alarm is triggered. With the auxilary circuit, maybe us it to power up a device that reverses the polarity of the OBD port so anyone who tries to use it instantly fries their machine.

A 50 cent diode is in most circuits to protect against polarity issues. Most aftermarket alarms have the immobilizer capability and alternate alarm setup you desire.
