One way to keep your car from being stolen is to have a kill switch in your car. But since new cars rarely are manufactured with these switches, you'll need to have a car mechanic install one for you or install one yourself. Here's how you can do it.

Step 1 – Gaining Access to Your Ignition Switch Wires

To install your kill switch you'll need to connect to your ignition switch wiring. This means you'll need to gain access to them and to know which wires to connect your switch to. To get this information, check your User’s Manual or call a car dealer's service department. To access these wires, remove the panel you find wrapped around your steering wheel.

Step 2 - Choose a Hiding Place to Mount Your Switch

Mount your switch inside your car where a car thief will least likely find it.

Step 3 – Connect Switch Wires

Cut a length of electrical wire long enough to run from your switch to your ignition wires and connect one end of them to your switch. Sever the two ignition switch wires used to start your car. Connect these wires to the wires you attached to your kill switch. Test your switch by starting your car with the switch in the "on" position, then test with it in the "off" position.
