While the brain acts as the command center of your alarm system, the sensors are the troops on the front line. Without them, or with them improperly installed, your system just isn't going to be effective. And remember, when positioning sensors in your car, make sure to test their coverage fully before screwing them down permanently.

Mount the sensors

1. Position the shock sensor near the center of your vehicle so it will detect shocks from the front and back, and attach it securely to a metal surface (it's a good idea to use existing body screws when you can, but it's also OK to drill holes and add new hardware as needed). As an alternative, you can strap the shock sensor down with nylon wire ties. Do not use Velcro or double-sided tape as they will absorb too much of the shock that your sensor is trying to detect.
2. Adjust your shock sensor's sensitivity to fit your needs, applying impact from all sides of the vehicle to test it. Keep in mind that an extremely sensitive setting yields the most false alarms.
3. Locate your motion sensor down low near the center of your vehicle. Do not mount your motion sensor until you have thoroughly tested its coverage area. You may have to try a few different spots before you find the one that gives you the best results.
4. If your system includes additional glass-break, sound, or other sensors, install them according to the manufacturer's instructions.

Pin switches

1. The pin (plunger-type) switches that come with most alarms are optional. In most cases, you can tie into the pin switches that are already in your car. The wiring sheet we provide for your vehicle will tell you where to look for them.
2. Pin switches can have either a negative (-) trigger or a positive (+) trigger. The vehicle wire color sheet supplied with this guide tells you which kind your vehicle uses.
3. Once you've accessed the switches, simply tap into the existing connection wire and attach it to the alarm brain. That way, for example, you can program the system to respond when the switch is moved (door opened) while the alarm is active.
