Car Alarm (490-0720) Installation Faxback Doc. # 6256
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
Electric Fan Trigger Wire (If your car has an electric fan on the
radiator)
If necessary, contact your vehicle dealer for information about your
vehicle's wiring.
Cautions:
Be sure your vehicle has a 12-volt DC, negative-ground electrical
system. If it does not, or if you are not sure, have a professional
alarm system installer install your alarm system.
For safety and to protect your alarm system, disconnect your vehicle
battery's negative (-) cable before you begin.
SELECTING A LOCATION FOR THE 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 car 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/l6-inch hole 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 the 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.
CONNECTION
The main control module has three color coded wires 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 - to engine cooling fan (If used)
Red - to +12 volts
Black - to ground
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).
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.
Do not connect the wires 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 tie 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
one of the wires that leads to 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 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.
Note: If your vehicle has a small dome light, it might not trigger the
alarm if you connect directly to your battery. In this case,
connect to a terminal on your vehicle's fuse box.
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 your
battery's cables 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 to 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 inserts in the cable connectors are not the size needed
to connect to the battery cables, 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.
COMPLETING THE WIRING
Recheck all connections to be sure they are correct and secure. 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, or turn the
ignition on for more than 6 seconds. Then turn off the ignition.
3. Follow the procedures in "Operation" to test the following.
Automatic Arming (See "Automatic Arming")
Remote Arming (See "Remote Arming")
Disarming (See "Disarming the System")
Sounding the Panic Alarm (See "Sounding the Panic Alarm")
Check the Motion Sensor's Sensitivity (See "Setting the Motion Sensor's
Sensitivity")
