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. (RLR/all-07/14/94)
