"The in line brake security lock. I used a hydraulic valve from a 1957 Douglas Airplane. When I leave the car, I push on the brake pedal and hit the hidden switch which locks on the brakes. The car cannot be pushed or towed as all four wheels are locked up. I also wired into this valve and switch a dead man alarm. If the power from the key is turned on and the lock is on, a warning buzzer goes off until either the key is turned off or the brake valve is deactivated by the hidden switch. When I go out and park the car, I don't have to worry as much.
