Stereo Cassette (120-1998) Installation Faxback Doc. # 6931 BEFORE YOU BEGIN THE INSTALLATION Before you install the stereo, carefully read all instructions and see if you can answer these questions about the vehicle's electrical and sound systems. * Does my vehicle have a 12-volt negative ground system? * Which of the stereo's wires is the power wire? * Which terminal on my vehicle's fuse box is for accessories? * How do I connect a wire to the fuse box? * Which stereo wires are line-level outputs and which are speaker outputs? If you are unsure about any of the above questions or any part of the installation process, we recommend you have a professional auto sound system installer complete the installation. Cautions: * If installation requires cutting or modifying your vehicle, or if obstructions are behind the mounting surface, we recommend you have a professional installer complete the installation. * Before you mount the stereo or install any speakers, temporarily connect the speakers, power wires, and antenna to test the stereo. Preparing the Mounting Area Before you mount the stereo, make sure you have all the necessary materials. Then confirm that the stereo fits your vehicle's stereo mounting area. The mounting area must be at least 7 inches (17.8 cm) deep. Note: If the mounting area is too large, you might be able to mount the stereo with an in-dash installation kit, available at your local Radio Shack store. Follow the installation kit's instructions to mount the stereo. Routing Speaker Wire If you install speakers, avoid routing the speaker wire near moving parts or sharp edges. You can usually route it along the wiring channel beneath the vehicle's door facings by carefully removing the molding that holds the carpet in place. After you route the speaker wire, replace the molding. Testing the Stereo Before you mount the stereo or any speakers you are installing, test the stereo by temporarily connecting the speakers, power wires, and antenna. Important: Do not cut these wires. If you cut any wire, you cannot obtain a refund or exchange on this product. Radio Shack will provide warranty service if you cut a wire and find the product is defective. MAKING THE CONNECTIONS The supplied 14-wire harness includes all the lead wires you need to connect the stereo to speakers, power, and optional components. You might need additional wire, depending on your individual auto sound system, to complete connections. Your local Radio Shack store carries a full line of wire and wire management accessories. Cautions: * For added safety and to protect your stereo, disconnect the cable from your vehicle battery's negative (-) terminal before you begin. * Be sure your speakers can handle 9 watts of power (4.5 watts per channel). Each speaker must have an impedance of at least 4 ohms. Your local Radio Shack store carries a full line of speakers. * You must connect a separate wire to each speaker terminal as described in the following procedure. Do not use a common wire or chassis ground for any speaker connection. Using an Adapter Harness If you are replacing an existing stereo, or if your vehicle has been factory-wired for autosound components, you might be able to use an adapter harness to connect the power and speakers. Radio Shack stores sell adapter harnesses for most vehicles. Follow the directions that come with the adapter harness to temporarily connect the power and speakers. Connecting the Speakers 1. Connect the gray wire to the right speaker's positive terminal. This terminal is usually marked with a plus(+) sign or red mark. 2. Connect the gray/black wire to the right speaker's negative terminal. This terminal might be marked with a minus (-) sign or it might not be marked at all. 3. Connect the white wire to the left speaker's positive terminal. 4. Connect the white/black wire to the left speaker's negative terminal. Connecting Power Follow these steps to connect ground and primary, memory backup, and remote power. 1. Connect the black ground wire to a chassis ground, such as a metal screw attached to a metal part of the vehicle's frame. Be sure that the screw is not insulated from the chassis by a plastic part. 2. Connect the yellow wire (with in-line fuse holder) to your vehicle battery's positive (+) terminal or to a fuse that provides a continuous source of 12 volts. The connection provides continuous power for the clock and tuner memory when the ignition is turned off. 3. Connect the red power wire (with in-line fuse holder) to a point in your vehicle's fuse block that has power only when you turn the vehicle's key to either accessory (ACC) or START position. This connection provides power to the stereo when you turn on the ignition or turn the key to ACC, and turns off power when you turn off the ignition. This prevents your vehicle's battery from being drained if you leave the stereo on when you turn off the ignition. 4. Connect the blue wire to any optional equipment that you want the stereo to turn on and off, such as a power antenna. This wire does not provide power to the component. It simply turns other equipment on or off. If you do not use this wire, secure it with a wire tie and do not let it touch metal. 5. Plug the 14-pin wire harness into the stereo's 14-pin wiring socket. Connecting the Antenna and the Battery Connect the vehicle's antenna cable to the stereo's large black antenna connector, then reconnect the cable to the vehicle battery's negative terminal. TESTING THE CONNECTIONS Turn on your vehicle's ignition and test the stereo. If the stereo does not work, immediately disconnect your vehicle battery's negative (-) terminal. Then, recheck your connections, or have a professional auto sound system installer install the stereo. After you test the stereo and verify that everything works, make sure the connections are correctly marked or identified. MOUNTING THE STEREO Be sure you test the stereo first and verify that it works properly. Follow these steps to mount the stereo. 1. Disconnect the cable from the vehicle battery's negative (-) terminal. 2. Temporarily disconnect the wiring harness and the antenna. 3. Insert the supplied sleeve into the dash. Then secure the sleeve to the dash by bending out the appropriate tabs with a screwdriver. Bend out all the side tabs. 4. Reconnect the wiring harness and the antenna. 5. Slide the stereo into the sleeve until it locks into place. 6. To further secure the stereo, use the supplied hardware to attach one end of the supplied metal strap to the back of the stereo. If necessary, bend the metal strap to fit your vehicle's mounting area. Then attach the other end of the strap to an existing bolt on a solid metal part of the vehicle. This strap also helps ensure proper electrical grounding of the stereo. 7. Reconnect the cable to the vehicle battery's negative (-) terminal. REMOVING THE STEREO FROM THE DASH 1. Disconnect the cable from the vehicle battery's negative (-) terminal. 2. Remove the metal strap attached to the back of the stereo. 3. Insert both of the provided keys into the slots at the lower left and right sides of the stereo. Then slide the stereo out of the dash. 4. Remove the keys from the slots by pressing the latches either below the keys or on the lower left and right sides of the stereo. 5. Disconnect the wiring harness and the antenna. 6. Reconnect the cable to the vehicle battery's negative (-) terminal. (smm 03/07/94)
