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 RELAY:
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
cause chaffing and shorting damaging the factory wiring. If an existing harness is
not available then secure the relay's metal mounting tab to an under dash metal
brace with a #8 self tapping sheet metal screw. Wire the relay as per the diagram
found later in this manual.
SHOCK SENSOR:
Select a centrally located, solid mounting surface for the shock sensor that will allow consis-
tent 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 installa-
tion.
14 Pin Main Harness
Red/White (5Amp) & Red Fused (15Amp) Wires : + 12 VDC CONSTANT BATTERY 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.
Yellow Wire: + 12 VDC IGNITION SOURCE
Connect this wire to a source that is live when the key is in the on and crank positions. Be
sure that this source is off when the key is in the off position.
White Wire: Positive Parking Light Flasher Output
This wire is the normally open contact of the on board parking light flasher relay. Connect this
wire to the vehicle parking light + 12 Volt feed wire.
Orange: Ground While Armed Output
This wire provides a 300 mA ground output when the alarm circuit is armed to control the
starter inhibit relay. Connect the Orange wire to terminal #86 (orange wire) of the relay
provided. Connect terminal #85 (red wire) of the relay to an ignition wire in the vehicle that is
+12 volts when the ignition switch is turned to the on and start positions and off when the key
is off. Locate and cut the low current start solenoid wire found at the vehicles ignition switch
harness. This wire will have + 12 volts when the ignition key is moved to the start (crank)
position and will have 0 volts in all other key positions. Connect one side of the cut wire to
terminal #87a ( Black wire) of the relay. Connect the other side of the cut wire to terminal #30
(White/Black wire) of the relay.
White w/ Black Trace Wire: (+) Siren Output
This is the positive siren feed wire. Route this wire through a grommet in the firewall to the
siren location. Connect the White w/ Black Trace wire to the Red wire of the Siren. Secure the
Black wire of the Siren to a known chassis ground or solid clean metal surface.
Brown Wire: Negative Door Trigger
If the vehicle's door courtesy light switches ground when the door is opened, (Most GMs and
Imports), you must connect this wire to the negative output from one of the vehicle's door pin
