Preparation, preparation, preparation!

Adding a security system is one of the most involved, complicated additions that you can make to your vehicle. Sure, it is possible for inexperienced hands to install a car security system, but it takes time, patience, and a careful plan of action. "Ready, Fire, Aim" is no way to go when taking on a project of this magnitude. First off, remember that you don't have to do it all in one day. Break the job into bite-size pieces and verify that each segment of the system works as intended before moving on.

For example:

Day 1 — Disconnect the negative terminal of your car battery — this will protect your electrical system from a short circuit, and you from contacting a live wire. Find a spot to mount the "brain" (control module) and siren. Hook the siren, LED indicator and valet switch to the brain, taking great care to route and connect the wires in a safe, secure way. Connect the power and ground leads to the brain. Test.

Day 2 — Position your sensors in their intended mounting locations and connect them to the brain. Test the coverage area of the sensors and make final adjustments before you fasten them down.

Day 3 — Tie into your door triggers and your power door lock circuit for keyless entry. Tie into your dome light and parking light circuits. Test these functions. When everything is working properly, secure the brain to the mounting surface.

Note: Set the parking brake and disconnect the negative battery terminal before attempting any installation.
