The Cateye is very simple to install.  Just follow the following guidlines

 1.   Attach the controller box to the rear firewall area using included nylon ties

 2.   Route the sensor cable down to the underside of the vehicle behind the engine.  take care not           to pin the  the heat protected cable agaist any hot surface3.  Use the nylon tie  to attach the               sensor securely to a location where it points toward the         converter.  There are        many             options.  It is best to mount the sensor in a       location that is even with,  or above the                       converter.      See  photos below for examples to suitable locations.


 3.   Attach the leads from the controller box to the car battery.  Red wire to the (+) battery post,                 Black to the  (-)  battery post.   


 4.    Once Installed,  press the "A"  button on the fob to activate the system.  The siren will sound              for   approximately 5 seconds and then turn off.  It may take a minute for the system to                        stabilize.        During this brief period, the sensor and siren may act a little erratic 

        (not respond, respond too much)


Controller Location

The controller box can be installed somewhere on the fire wall.  The battery leads are about 3.5 feet long,  that should be enough to reach to the battery.

The reason that the firewall is a preferable location is that the sound will be focused down underneath the car, making for maximum volume level.


Sensor Location

Route the sensor cable from the control box down behind the engine to the bottom of the car.   The sensor can be mounted anywhere within the reach of the cable.  It is important to mount the sensor higher than the catalytic converter.  It is very sensitive and has an extremely wide area of vision.  If its mounted too low, it may activate when someone merely approaches the car.  You may want to experiment a bit with the exact location before you fix it in place.

Note that is small and dark - so its not going to be easily found and disabled by an intruder.

Pointing the sensor directly at the converter or directly down to the ground may cause issues with false alarms. We recommend the sensor be positioned near the front of the vehicle looking from front to back so it can scan the entire underside of the vehicle. Ideally it should be positioned so the majority of its field of view is not obstructed within 12 inches of the "eye".
