INST ALLATION OF THE MAJOR COMPONENTS:
CONTROL MODULE:
Select a mounting location inside the passenger compartment (up behind the dashboard). The
mounting location selected must be within 24" of the ignition switch wiring harness to allow
connection of the 6 pin main wiring harness.
Be certain that the chosen location will not interfere with proper operation of the vehicle. Avoid
mounting the module to or routing the wiring around the steering shaft/column, as the module or
wiring may wrap around or block the steering wheel preventing proper control of the vehicle.
Secure the module in the chosen location using cable ties or screws as necessary.
Do Not Mount The Module In The Engine Compartment, as it is not waterproof.
DASH MOUNTED LED:
The small LED included in the kit will serve as a visual indicator of the alarm's status and
provide a visual deterrent to a potential thief. The LED also provides important feed back information during the transmitter and feature program modes. The LED should be installed in the
dash in an area highly visible so that it may be seen from the driver's seat as well as from outside
the vehicle. Inspect behind the chosen location to insure that the drill will not penetrate any
existing factory wiring or fluid lines. Carefully drill a 1/4" hole in the desired location and pass the
connector end of the LED through the hole and toward the control module. Press the LED firmly
into place until it is fully seated in the mounting hole.
THE RECEIVER/ANTENNA ASSEMBLY :
The Super-regenerative Receiver Antenna Assembly provided with this unit allows routing from
below the dash board for maximum operating range. Choose a location above the belt line
(dashboard) of the vehicle for best reception. Special considerations must be made for windshield glass as some newer vehicles utilize a metallic shielded window glass that will inhibit or
restrict RF reception. In these vehicles, route the antenna toward a rear window location for best
reception. Secure the antenna with double stick tape provided. After securing the antenna with
tape, we advise also securing a section of the antenna cable to a fixed support. This will prevent
the antenna from dropping down in case the double stick tape is exposed to extreme heat which
may loosen it's gummed surface. Route the connector toward the control module using caution
not to pinch the cable as this will cause poor or no RF reception to the control module.
VALET/PROGRAM/MANUAL OVERRIDE SWITCH :
Select a mounting location that is easily accessible to the operator of the vehicle. It is not
necessary to conceal the switch. However, concealment is recommended as it offers a higher
level of security . The switch can be mounted to the lower dash p anel in the driver's area. Inspect
behind the chosen location to insure that adequate clearance is allowed for the body of the
switch, and also that the drill will not penetrate any existing factory wiring or fluid lines. Drill a 9/
32" hole in the desired location and mount the switch by passing it through the panel from the
underside. Secure the switch using the nut, star washer. Route the switch's connector toward
the control module.
NOTE: During the program sequence, there are times when this switch and the ignition switch
SIREN:
Select a location in the engine compartment that is not accessible from below the vehicle. The
selected location must be clear of hot or moving parts within the engine compartment The siren
must be pointed downward to prevent water retention and the flared end must be pointed away
from and out of the engine compartment for maximum sound distribution. Before securing the
siren, check behind your chosen location to assure that the mounting screws will not penetrate
any factory wiring or fluid lines. Secure the siren mounting bracket using #8 self taping screws or
by first using the mounting bracket as a template, scribe or mark the mounting holes. Drill the
marked holes using a 1/8" drill bit, then mount the siren using #8 sheet metal screws.
HOOD PIN SWITCH:
The pin switch included in this package are intended for protecting the hood area of the vehicle.
In all cases, the switch must be mounted to a grounded metal surface. When the pin switch is
activated, (hood/trunk open), it will supply a ground to the input wire activating the alarm. In
addition, the hood switch is required for the safety shut down of the remote start unit. If the
vehicle is being worked on, this hood switch prevents the remote start activation even if the RF
command to start is issued. This switch must be installed in all applications. Failure to do so
may result in personal injury or property damage.
Mount the switch in the hood locations away from water drain paths. If necessary, the included
bracket may be used to move the switch away from rain gutters or allow mounting to the firewall
will be used simultaneously. We recommend that the pushbutton switch be mounted
on the left side of the ignition switch to facilitate this operation.

behind the hood seal. In both cases the switch must be set up to allow the hood to depress the
switch at least 1/4 inch when the hood is closed and fully extended when the hood is opened.
For direct mounting, a 1/4 inch hole must be drilled. Carefully check behind the chosen location
to insure the drill will not penetrate any existing factory wiring or fluid lines.
Drill a 1/4" hole in the desired location and thread the pin switch into it using a 7/16" nut driver
or deep well socket. If using the mounting bracket, first secure the bracket to the desired
location and secure the pin switch in the pre-threaded mounting bracket hole.
STARTER INHIBIT RELA Y :
Select a mounting location within 6" of the ignition switch's low current start solenoid wire.
Secure the relay to an existing harness in the chosen location using a cable tie around the
relay's wiring harness.
CAUTION! Do not wire tie the metal bracket to an existing wiring harness as vibration may
SHOCK SENSOR:
Select a centrally located, solid mounting surface for the shock sensor that will allow consistent operation from all areas of the vehicle. The selected location must be within 24" of the
control module to allow routing and connecting of the 4 pin harness. Secure the shock sensor
to the chosen location using two #8 self tapping sheet metal screws. The sensor can also be
secured to an existing dash brace using cable tie straps. Whichever mounting method is used
be sure to allow access to the sensitivity adjustment potentiometer for use later in the installation.
14 Pin Main Harness
Red/White (5Amp) & Red Fused (15Amp) Wires : + 12 VDC CONSTANT BA TTERY SOURCE
This wire controls the sensitivity of the voltage sensing circuit, which detects the turning on of an
interior light when a door is opened. It will also detect the switching on of parking or headlamps,
and in many cases will trigger the alarm when a thermostatically controlled electronic radiator
cooling fan switches on.
When installing this system into vehicles with electronic “ after fans “, it is recommended you
disable the voltage sense circuit.
In voltage sensing applications, the closer to the battery that the red wire is connected, the less
sensitive the voltage sense circuitry will be. Moving this connection point to the fuse panel will
increase the sensitivity, and connecting to the courtesy lamp fuse in the vehicle will provide
maximum sensitivity of the voltage sense circuit. Be certain to set selectable feature # 7 to 1
chirp, Voltage Sense On.
When hardwiring the control module to pin switches at all entry points, the voltage sense circuit
must be disabled.
NOTE: If the vehicle's parking lights are ground switched, connect this wire to chassis ground.

switches. In most cases the Brown wire will need to be connected to only one door switch no
matter how many doors the vehicle has as most door lighting circuits are wired in parallel. This
wire will be shunted when remote starting the vehicle and will remain shunted, if active, while
running under command of the remote start. If this wire is active when the system is armed, the
siren will emit three chirps. When the zone clears, the siren will emit 1 chirp to confirm full arming.
NOTE: For vehicles with interior delay lighting see programming under title "Completing The
Purple Wire: (+) Door Trigger Input
If the vehicle's door courtesy light switches + 12 volts when the door is opened, (Some Fords and
some Imports), you must connect this wire to the positive output from one of the vehicle's door pin
switches. In most cases, the Purple wire will need to be connected to only one door switch no
matter how many doors the vehicle has as most door lighting circuits are wired in parallel. This
wire will be shunted when remote starting the vehicle and will remain shunted, if active, while
running under command of the remote start. If this wire is active when the system is armed, the
siren will emit three chirps. When the zone clears, the siren will emit 1 chirp to confirm full arming.
See below for wiring details.
Note for vehicles with interior delay lighting see programming under title "Completing The Installation".
