Do It Yourself

a thief can disarm the alarm and steal the car.  The alarm override switch should be mounted in someplace hidden but convenient.  Good locations include behind the hood release lever, inside the ashtray opening, inside the center console (where it can’t be accidentally bumped), or in theglove box.  Before drilling, check for clearance on both sides.

7. SECURE THE SHOCK SENSOR (Alarm Installations Only):
  Shock or impact sensors are the most common sensors included with vehicle security systems. They are designed to detect various degrees of impact to the vehicle during a break-in attempt. Some shock sensors have a dual-stage response. A light shock to the vehicle may only chirp the siren and/or flash the parking lights to warn away a potential thief or intruder. A heavy shock will trigger the alarm. These sensors are most effective in detecting a punched-out door lock. However, when adjusted to be sensitive enough to detect breaking glass, they will false alarm.  The shock sensor should be securely mounted underneath the dash.
  Use double sided tape or a wire tie to secure it to an air duct, wire harness, or trim panel.   Avoid mounting it in the way of any moving parts or relays. Avoid mounting it to the steering column or screwing it to metal, as it will cause poor sensitivity

8. SECURE THE RADAR, MICROWAVE, and FIELD DISTURBANCE SENSORS (Alarm Installations Only):
  These sensors are very useful in helping protect vehicle contents. They flood the area to be protected with a microwave energy field. When the field is disturbed by a large mass such as a human body, the sensor sends a trigger to the alarm control unit to trigger the alarm. The larger the object the faster the sensor will react. These sensors are ideal for protecting convertibles and vehicles with removable tops.   Like most car alarm..  If your vehicle has a center console between the front seats, mounting the sensor under this console facing up may be an ideal location. Make sure that the sensor is not placed behind any metal parts or major harnesses of the car. The sensor will detect through fabric or plastic, and it needs to face towards the area that is to be protected.   The sensor should always be adjusted outside, away from any fluorescent lights. These lights, as well as temperature, and weather conditions can affect the
sensitivity of these sensors.

9. LOCATE AND CONNECT TO TACHOMETER WIRE (Remote Start Installations Only):
  Remote starts have a tachometer wire input to monitor the tachometer signal when the vehicle is remote started
  A multi-meter capable of testing AC voltage is needed to test for the tachometer wire.
  The tachometer wire will meter between 1V and 6V AC.
  Common locations for the tachometer are the ignition coil, instrument cluster, engine computers, or test connector.
