PRE- INSTALLATION CONSIDERATIONS
To ease installation, we suggest that you READ THIS MANUAL before beginning your installation.
BEFORE BEGINNING , check all vehicle manufacturer cautions and warnings regarding electrical service
(AIR BAGS, ABS BRAKES, ENGINE / BODY COMPUTER AND BATTERY).
PLAN OUT YOUR INSTALLATION and determine most suitable locations for all components to be
placed.
These components include: the module itself, valet/ program button and possible relays. Allow enough
wire to create a service loop with strain relief, should servicing be required.
DAMAGE resulting from incorrect installation or failure to follow guidelines stated in this book will not be
covered under warranty and subject to repair or replacement charges.
USE A VOLT/ OHM METER to test and locate all connections. Test Lights can damage a vehicle’s
computer systems.
ADDITIONAL PARTS , which are not included with this unit, may be needed for your particular vehicle. .
These items may include extra relays or Special “Data Bus” interface modules.
DO NOT ROUTE ANY WIRING THAT MAY BECOME ENTANGLED with brake, and gas pedals,
steering column, or any other moving parts in the vehicle.
REMOVE MAIN SYSTEM FUSE (S) before jump starting the vehicle or charging the vehicles battery.
COMPONENT MOUNTING
CONTROL MODULE: Locate the module underdash as high as possible. Driver’s Side usually provides
an easy location for the majority of the wiring connections. The antenna wire should be routed away from
any metal if possible. DO NOT alter the length of the antenna wire, or ground the antenna wire.
OVERRIDE / PROGRAM BUTTON: Mount the button in a hidden but accessible location. It is used for
emergency- disarm (when optional starter disable is installed) without the use of the transmitter and for
programming features of this unit.
LED : The optional Red LED provides a useful theft deterrent. The LED blinks after you lock the vehicle
with your remote simulating an alarm system. The LED is also required when programming options.
Choose a visible location in the dash or console for the LED’s location.
WIRING
WHITE WIRE: +12V or (-) NEGATIVE PARKING LIGHT (Jumper Selectable On- Board Relay 10A)
Connect to switched +12V parking light wire at back of light switch. If this is not possible, connect directly
to one of the parking lights at the front of the vehicle. If your vehicle requires a (-) Negative Ground signal
to activate the parking lights, then you have to open the control and move the jumper located on the
circuit board inside the unit. For European vehicles with separate right and left circuits, use a dual relay or
2 diodes to separate the output signal. The DEFAULT output is POSITIVE.
BLACK/ YELLOW WIRE: (-) AUXILIARY REMOTE OUTPUT 3 (Optional, requires relay)
This wire provides a Negative output for activation of optional or auxiliary devices. It is controlled by
Pressing and Holding Buttons (2) Unlock and (4) Panic together.
BLACK/ WHITE WIRE: (-) NEG. or +12V DOME LIGHT (Jumper Selectable On- Board Relay- 10A)

3
Connect to dome light activation circuit for Negative type circuits. For Positive type circuits, open the
control module and move the jumper the plug as shown in illustration.
The DEFAULT is NEGATIVE.
BLUE/ WHITE WIRE: (-) PASSENGER( S) DOOR UNLOCK OUTPUT (Optional, requires relay)
Connects to unlock circuit for passenger door( s) when using separate driver’s door unlock option. See
DOOR
LOCK WIRING for configuration options.
WHITE/ RED WIRE: (-) AUXILIARY REMOTE OUTPUT 2 (Optional, requires relay)
This wire provides a Negative output for activation of optional or auxiliary devices. It is controlled by
Pressing and Holding Button (1) Lock.
ORANGE WIRE: NEGATIVE ARMED OUTPUT
This wire provides a constant GROUND output when system is locked with the remote transmitter. This
output can used for a starter disable relay, or a device such as a window roll- up module. See System
Wiring Diagram.
GRAY WIRE: (-) AUXILIARY REMOTE OUTPUT 1 (Optional, requires relay)
Negative output controlled by pressing Button #3 (Trunk Symbol) for at least 1 second.
BROWN/ WHITE: (-) HORN HONK/ CHIRP OUTPUT (Optional, requires relay)
This wire provides a negative pulse output to honk/ chirp the factory horn for audible lock/ unlock
confirmation. Connect Brown/ White to terminal 85 of a relay. Connect terminal 86 to +12V Constant.
Connect terminal 87 to +12V or GROUND depending on the type of horn activation circuit in the vehicle.
Connect terminal 30 to the horn activation circuit. NOTE: Many vehicles use a Negative type of horn
circuit, however we recommend that you test the circuit on your vehicle before making any connections to
avoid any possible damage.
GREEN WIRE: NOT USED (No Connection)
YELLOW WIRE: IGNITION SWITCHED “ON” AND “START” +12 VOLTS
Connect to an ignition wire that shows +12 Volts when the key in both “On” and “Start” positions.
BLACK WIRE: SYSTEM CHASSIS GROUND
THIS WIRE MUST BE CONNECTED TO CHASSIS METAL OF THE VEHICLE. Scrape away any paint or
dirt from the connection point to ensure a good connection. Keep ground wire short.
RED WIRE: +12V POWER INPUT (15 amp fuse)
Connect to +12 Volt source with supplied fuse & holder. Recommended location for this connection is at
the vehicle battery positive terminal.

This option modifies the unit’s (-) Negative Armed Starter Disable output operation. When this option is
turned ON, the unit will PASSIVELY activate the Starter Disable 45 seconds after the ignition is turned off.
Starter disable output is deactivated through the remote when unlocking the vehicle or a manual override.
6. IGNITION TRIGGER
This option controls the unit’s optional Ignition trigger feature. If selected to ON, then the vehicle’s horn
will honk if an unauthorized operator turns on the Ignition after the vehicle had been locked with the
remote. This function is similar to an alarm system. To avoid a trigger, use the remote for BOTH
LOCKING and UNLOCKING the vehicle. If system accidentally triggers, press button #4 to reset.
7. EXTENDED HORN CHIRP
This option allows the unit to provide a slightly longer lock/unlock horn chirp output. This option is ONLY
required on specific vehicles where the normal horn chirp is not long enough to activate the factory horn
and produce a chirp.
OPTION RESET: RESTORES PROGRAMMING OPTIONS TO FACTORY DEFAULT SETTINGS:
1. Turn the Ignition ON, wait one second, and press the Override/Program button 5 times.
2. The system will flash the LED 5 times
3. Press Button #3 (Trunk). Lights will flash 4 times and horn will chirp (if optional horn chirp installed) 4
times. All options will be returned to factory default setting. Default settings are marked with an “*”
