Remote Control Alarm (490-0770) Installation Faxback Doc. # 16054 System The control module mounts in the interior of the vehicle for easy accessibility. From this location, wires lead to the siren. The wiring harness' nine wires connect the control module to the vehicle battery's positive and negative terminals, the siren, the door switches, points in the vehicle's fuse block, and the hood and trunk pin switches. MOUNT THE INDICATOR MODULE Choose a location on the front of the dashboard near the driver's door window so the indicator module is clearly visible from outside the vehicle. Clean the mounting surface with soap and water. Use the provided double- side adhesive tape to attach the indicator module to the chosen location. CONNECT THE WIRING Different connectors are included with the alarm system. The main module has a color-coded wiring harness for easy connection. You must run each wire to a different part of the vehicle. Keep the following hints in mind when wiring the alarm system: Avoid sharp edges 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 siren and pin switch wires (such as the opening for the speedometer cable.) For best appearance and protection against accidental or intentional disconnection, run the wires under carpet or trim, so they are not visible to the casual observer. CONNECT THE WIRING HARNESS The wiring harness connects the control module to the chassis ground, 12-volt DC power, door switches, hood and trunk switches, and the ignition. 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. Avoid sharp edges and moving parts. Connect Power Connect the wiring harness' red wire with inline fuse to a continuous source of 12 volts. You can connect it directly to the battery's positive terminal or to a non-switched fuse terminal (a terminal that the vehicle's ignition does not turn on and off). Ground the Control Module Route the black wire from the wiring harness' location to a metal screw attached to the vehicle's frame or firewall or directly to the battery's negative terminal. Be sure to clean the contact surface before you connect the ground wire. NOTE: If you connect the wire to a metal screw, be sure the screw is not insulated from the chassis by a plastic part. Wire the Door Switches This system uses the existing door switches to activate the alarm. First determine which of the following door switch connections the vehicle has. Many vehicles have a single connection at the dome or courtesy light that connects to each door. If the vehicle has this wiring system and the vehicle does not have a delayed dome light, use the instructions below for your type of vehicle. If, however, the vehicle has a dome light that turns on before you open the door or delays turning off after you close the door, we recommend you have a professional install the system. If you are not sure what type of door switch the vehicle has, contact the vehicle dealer. All Domestic Ford Products Route the violet wire to the door switch wire that leads to the dome or courtesy light. With the supplied squeeze connector, connect the violet wire to the door switch wire. This connects the terminal to chassis ground when the door is closed, and +12 volts when the door is opened. General Motors, Audi, BMW, Chrysler, Datsun/Nissan, Fiat, Fiesta, Isuzu, Mazda, Renault, Subaru, Toyota, Volkswagen and Volvo Route the gray wire to the door switch wire that leads to the dome or courtesy light. Connect the gray wire to the door switch wire using the supplied squeeze connector. This connects the +12 volts when the door is closed, and to the chassis ground when the door is opened. Other Vehicle Makes Use a voltmeter or test lamp to determine whether the separate door switch wires or the single wire leading from the door switch to the courtesy light is connected to +12 volts or the chassis ground when the door is opened. If they are connected to +12 volts when the door is opened, use the provided violet wire. If they are connected to +12 volts when the door is closed, use the gray wire. NOTE: Mercedes switches vary with each model. Some might use both wires. Check with your vehicle dealer. CAUTION: If you make connection to a single door switch wire in the dome or courtesy light, use either the gray wire or violet wire, but not both. Using both wires could damage the alarm system. Wire the Ignition Lead Route and connect the wiring harness' blue wire to the ignition (IGN) terminal in the fuse block. This connection provides 12-volts of power to the blue wire when you turn on the ignition, and turns off power when you turn off the ignition. Wire the Pin Switches Follow these instructions to connect the pin switches to the control module. 1. Route the wiring harness' brown wires to the hood or the trunk pin switch. 2. Plug the brown wire's bullet end into each pin switch. ROUTE THE SIREN WIRE Route the siren's wire to the interior of the vehicle and to the harness' yellow wire. NOTE: Many cars have predrilled holes for routing wires. If the vehicle does not have predrilled holes, drill a 1/4-inch (6.5 mm) hole through the engine compartment's firewall (the steel wall between the engine compartment and the interior of the vehicle) into the interior of the car. Select the location for this hole carefully to avoid drilling through any mechanism or wiring. SET THE SECURITY CODE The security code helps eliminate false triggering by similar systems. To set the security code, do the following: 1. Open the control module's code compartment by pressing down and sliding the cover in the direction of the arrow. NOTE: Leave the control module's code compartment open until you make the connections described in the following sections. 2. Set the dip switches, located in the control module to any +, 0 and - combination. NOTE: The diagram on the top of the control module is only an example of a setting. You can set the switches to any position as long as you do not set them all to the same position. 3. Remove the screw from the back of the remote arm/disarm transmitter and lift off the top cabinet of the transmitter. 4. Set the dip switches to the same combination you used for the control module. 5. Replace the top cabinet of the transmitter and secure it using the screw. CONNECT THE CONTROL MODULE You are now ready to connect all components to the control module. Near the mounting location of the control module, you should have a 9-wire socket, each wire representing one of the following: the sire, the wiring harness, or the indicator module. To connect these sockets to the control module, do the following: 1. Insert the socket into the module. 2. Reconnect the vehicle's battery cable to the battery's negative (-) terminal. MOUNT THE CONTROL MODULE You can mount the module in the trunk or under the dash using the mounting tabs on each side of the control module. To mount the module, you might need to drill pilot holes, using the mounting tabs as a guide. Insert the provided screws through the tab's mounting holes and into the mounting location. TEST THE SYSTEM To test the system and activate the codes, do the following: 1. Close all doors, the hood, and the trunk. 2. Start the vehicle and let it run for more than 6 seconds, or turn the key to the ON position for more than 6 seconds. Then, turn the key to OFF. 3. Test the system using the procedures in the "Operation" section. Test the following: Automatic Arming and Disarming Transmitter Arming and Disarming Panic Alarm Motion Sensor Exit and Entry Delays NOTE: If the system fails to operate properly, disconnect the socket from the control module. Then, proceed to the check all other connections. (LLG/all-07/21/95)
