We find this circuit in an American publication of 1978. It is intended only for cars that have contact breaker, because their action is precisely to prevent the operation of this component of the ignition, thus paralyzing the vehicle. The transistors can be the BD135 and the circuit is connected in the courtesy light system, being triggered when the doors are opened. The circuit can be adapted for cars without contact breakers.
