Remote Control Talking Alarm System (490-0740) Preparation Faxback Doc. # 31175 This alarm system includes a main control center, two key-chain remote transmitters, LED indicator, extension wire, and mounting hardware. Before you install the system, read the entire installation section and decide where to mount the control center and route all wiring. Be sure all wires can reach their connection locations. The control center mounts in the engine compartment. The wiring harness' three wires connect the control center to the vehicle battery's positive terminal, the cooling fan, and an accessory (ACC) terminal that has power only when your vehicle's ignition is on or set to accessory (ACC). The diagram at the end of the manual can help you understand how the system works when it is properly installed. (SP/RF 3/8/96)
