Car Security

Starter Interrupt

The starter interrupt, referred also as a starter disable, is an interruption in the electrical current that flows to the car's starter when you turn the key. It installs in between the ignition switch and starter solenoid, and can be controlled via switch or relay, activated by the security system. When activated by either method it will not allow the vehicle to start. Around the lower steering column the application can be achieved. The relay and relay socket will simpilfy the procedure and is recommended in this installation.
