area of the vehicle. It houses the microprocessor which monitors your vehicle
and controls all of the alarms functions.

which prevents the vehicle’s starter from cranking whenever the system is
armed. The vehicle is never prevented from cranking when the system is
disarmed, in Valet

mode, or should the starter kill switch itself fail. Your
system is ready for this feature, however installation of this feature may
require additional labor.

sensor, pinswitch or to existing systems in the vehicle, such as ignition or
courtesy lights.
