Vehicle Alarm System (490-0721) Installation Faxback Doc. # 6907
To install the system, you must be familiar with your vehicle's wiring
system. For example, you must be able to identify the following:
Chassis Ground
Constant +12 Volts
Starter Solenoid
Trigger wire for the Automatic Fan
Door Switch Wire
If necessary, contact your vehicle dealer for information about your
vehicle's wiring.
Before installing the alarm system, read this section carefully. If you
are unsure about any part of the installation process, we recommend you
have a professional alarm system installer install the system.
Cautions:
Be sure your vehicle has a 12-volt DC, negative-ground electrical
system.
For safety and to protect your alarm system, disconnect your vehicle
battery's negative (-) cable before you begin.
SELECTING A LOCATION FOR THE MAIN CONTROL MODULE
1. Open the hood of your car to expose the engine.
2. Find a place to mount the control module where it is away from moving
parts and excessive engine heat. DO NOT ATTACH THE CONTROL MODULE TO
THE ENGINE.
The short green wire located at the base of the control module is your
system's antenna. DO NOT ATTACH IT TO METAL AND DO NOT CUT IT. For the
best remote arm/disarm transmitter range, the antenna should not be
blocked by metal parts, and should hang straight down. If you can, mount
the control module near the front of your vehicle so the antenna is near
the front grille.
MOUNTING THE INDICATOR
Select a location on the front of the dashboard near the driver's door
window so you can clearly see the indicator from outside the vehicle.
1. Take apart the indicator assembly. There are two parts, the
indicator with the wire harness, and the plastic housing.
2. Drill a 5/16-inch in the mounting surface, being careful not to drill
into mechanisms behind the surface.
3. Insert the indicator from the front with the connector first. Make
sure the indicator head does not slip into the hole completely.
Leave about 6 inches of wire hanging from the hole.
4. Insert the housing over the indicator's head. Snap the indicator and
the housing into the hole.
5. Route the indicator's wires to the control module's position, taking
care not to route the wire over hot, sharp, or moving parts.
6. Plug the indicator's two-pin connector into the control module's
corresponding connector.
CONNECTING THE WIRING HARNESS
The wiring harness connects the control module to the engine cooling fan
motor (if your car has one), 12-volt DC power, chassis ground, and the
starter solenoid. The main control module has a color-coded live-wire
harness for easy connection.
Caution: Disconnect your vehicle battery's negative (-) cable before you
make any connection to your vehicle's electrical system.
You must run each wire to a different part of your vehicle.
Yellow - Electric Engine Cooling Fan (If Used)
Red - Constant 12 Volts
Black - Ground
Pink - Armed Output (Optional)
White - Door Trigger
Brown (Pair) - Starter Kill
Keep the following hints in mind when wiring the alarm system.
Avoid sharp edges, moving parts, and places where the wire might be
accidentally pinched or cut.
In the engine compartment, run wires along the body away from hot or
moving engine parts.
Try to find an existing hole in the firewall for running the wire to
the fuse block (if you choose this option, see "Connecting to Power
and Ground").
For the best appearance and protection against accidental or intentional
disconnection, run the wires under carpet or trim, so they are
not visible and cannot be tampered with without opening your vehicle.
Before connecting the wiring harness, place it next to the control
module. Do not connect it to the module at this time, but route each
wire from this location to be sure each wire reaches from the control
module's location to its connection point.
Connecting to an Engine Cooling Fan
If your vehicle does not have an electric engine cooling fan that turns
on to cool the engine, even after you turn off the vehicle's ignition,
coil up the yellow wire and secure it with a wire wrap or tape.
If your vehicle has an electric fan that turns on after you turn off the
ignition, you must connect the yellow wire from the main control module to
the power lead on the fan housing. This prevents the fan from causing
your alarm to sound a false alert.
Follow these steps to make the connection.
1. Slide the blue plastic splicing connector under one of the fan's
power wires so the wire rests in the connector's outer channel.
2. Slide the end of the main control module's yellow wire into the
connector's inner channel so the splicing teeth bite firmly into the
top.
3. Use pliers to press the two halves of the connector together until
they click shut.
Connecting to Power and Ground
You must connect the control module to a source of 12-volt DC power that
does not turn off when you turn off or operate your vehicle's ignition
switch. For the best operation and easiest installation, we recommend
you connect directly to your vehicle's battery. You can connect to a
terminal on your vehicle's fuse box instead if this is easier for your
installation.
Follow these steps to connect the control module to the vehicle's battery
cables.
1. Locate your vehicle's battery. Identify the positive (+/red) cable
and the negative (-/black) cable attached to the battery.
2. Install the supplied large blue cable connectors on each of the
battery's cables, near the battery as follows:
Warning: When handling the battery's positive (+/red) cable, do not let
the cable, the cable connector, or the pliers you use to clamp
the connector touch any other part of your vehicle. Doing so
would cause a direct short across your vehicle's battery. This
generates extreme heat and could even make your vehicle's
battery explode.
a. Remove the screw securing the cable connector's metal clamp and
slide the clamp out of the connector.
b. If the plastic insert in the cable connector is not the size
you need to clamp snugly onto the battery cable, remove the
insert and either install the other insert or, for a large
cable, leave the connector without an insert.
c. Place the connector over the cable.
d. Slide the clamp into the connector. Then use pliers to press
the clamp onto the cable so the clamp's spike presses through
the cable to contact the cable's conductor. Secure the clamp
using the screw you removed in Step a.
3. Plug the red wire from the control module into the blue connector on
the positive (+/-red) battery cable.
4. Plug the black wire from the control module into the blue connector
on the negative (-/black) battery cable.
Or follow these steps to connect the control module to your vehicle's
fuse box.
1. Attach the black (-)wire from the control module into the blue
connector on the black battery cable.
2. Run the red wire from the control module through the firewall.
Attach it to a terminal on the fuse block that has +12 volts even
when the ignition is off or when you operate the ignition switch.
Connecting the Armed Output
To install other modules, such as an optional door lock, connect the pink
wire to the option's control input.
Connecting the Door Trigger Input
To use alarm's automatic arming feature, you must connect the white wire
to the driver-side door's pin switch.
Attach the white wire directly to an existing door pin switch or install
a pin switch (not included) on the door.
Connecting to the Starter Kill Switch
Your alarm system has a relay which can interrupt the starter circuit
while the alarm is sounding. Follow these steps to install this feature
in your vehicle.
Caution: Do not cut the thick, red power cable that connects the starter
solenoid to the battery. If you do not fully understand this
procedure, contact a professional alarm system installer.
Damage to your car's electrical system can be costly to
troubleshoot and repair.
1. Locate your vehicle's starter solenoid. This is a box or junction
point where the battery's large red cable ends. If your vehicle's
battery cable runs from the battery to a post nearby, follow the large
red cable from that point to a box on the engine.
2. Locate a smaller wire which runs from the starter solenoid to the
ignition switch on the steering column.
3. Disconnect the smaller wire. Reconnect your vehicle's negative
(/black) battery cable and confirm that the engine does not start by
trying to start the vehicle.
4. After you confirm that the vehicle will not start, disconnect your
vehicle's negative battery cable again. Then trace the starter
solenoid wire back to a convenient place and cut it.
5. Use the blue plastic splicing connectors to attach one of the brown
wires from the main control module to one end of the ignition wire
you cut.
6. Attach the other brown wire to the other end of the wire you cut.
COMPLETING THE WIRING
Recheck all connections to be sure they are correct and secure. Then
plug the wiring harness into the control module. Finally reconnect the
negative (-/black) cable to the battery. You will probably have to reset
your vehicle's clock, radio, and any other electronic device in your
vehicle that uses vehicle battery power for memory backup.
SETTING SECURITY CODES
The security codes for each remote transmitter help eliminate false
triggering by similar systems. Follow these steps to set the security
codes immediately after you connect the system to power.
1. Make sure the hood, trunk, and all doors are firmly closed. The
indicator lights steadily.
2. On one of the remote controls, press either button once. The system
chirps once.
3. On the second remote control, press either button once. The siren
chirps twice and the indicator turns off. The control module is now
programmed to respond to only these two remotes and the system is
disarmed.
Note: If you want only one remote to operate the system, use the same
remote for Steps 2 and 3.
To set the system to use different remotes, disconnect the system from
all power. Then reconnect the power and repeat Steps 1 and 2.
TESTING THE SYSTEM
Follow these steps to test the system and activate the security codes.
1. Close all doors, the hood, and the trunk.
2. Start your vehicle and let it run for more than 6 seconds. Then turn
off the ignition.
