In-Dash High-Power AM/FM Stereo Cassette with Auto-Reverse (120-2108) Installation Faxback Doc. # 32409 Before You Begin the Installation Before you install your stereo, read all the instructions in the "Installation" section of the manual. You should be able to answer all of these questions about your vehicle's electrical and sound systems. Which terminal in my vehicle's fuse box is for accessories? How do I connect a wire to the fuse box? Which of the stereo's wires is the power wire? Which stereo wires are speaker outputs? Also, be aware that installation in your vehicle might require cutting or modifying your vehicle. Before you mount the stereo, test the connections by temporarily connecting the power wires, speakers, and antenna as described in "Making the Connections", below, and install the control panel as described in "Installing the Control Panel", below. If you plan to use an adapter harness to connect the stereo, see "Using an Adapter Harness", below. Preparing the Mounting Area Before you mount the stereo, read through this "Installation" section to make sure you have all the necessary materials. Then confirm that the stereo fits your vehicle's mounting area. CAUTION: Be careful to avoid obstructions behind the mounting surface. NOTES: This autosound stereo system is a DIN-E size unit that requires a 2 1/8 inches (54 mm) high by 7 1/2 inches (190 mm) wide by 8 1/2 inches (216 mm) deep mounting area. 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 wires 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 wires, replace the molding. Making the Connections The supplied 14-wire harness includes all the lead wires you need to connect the stereo to ground, power, optional components, and speakers. You might need additional wire, depending on your individual auto sound system, to complete the connections. Your local Radio Shack store carries a full line of wire and wiring accessories. 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. CAUTIONS: For added safety and to protect your stereo, disconnect the cable from your vehicle battery's negative (-) terminal before you begin. You MUST connect the ground, primary, and memory backup wires first, then test these connections before you make any other connections. If you do not make the connections in the order shown, damage to the stereo is possible if any wire connections are made incorrectly. 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. Your local Radio Shack store sells adapter harnesses for most vehicles. Follow the directions that come with the adapter harness to connect power and the speakers. Connecting Ground, Power, and Optional Components Follow these steps to connect the 14-wire harness to ground, primary and memory backup power, and optional components. 1. Disconnect the cable from your vehicle battery's negative (-) terminal. 2. 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. 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 the accessory (ACC) or ON position. This connections powers the stereo and turns it on when you turn on the ignition or turn the key to ACC, and turns off the stereo 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 yellow power / memory wire (with in-line fuse holder) to your vehicle battery's positive (+) terminal or to a point in your vehicle's fuse block that provides a continuous source of 12 volts. This connection provides continuous power for the stereo's clock and tuner memory when the ignition is turned off. 5. Connect the blue / white wire to any optional component, designed to run from a switched source, that you want to turn on and off when you turn the stereo on and off (such as an equalizer / booster). This wire does not provide power to the component. It simply turns it on or off. If you do not use this wire, secure it with a wire tie and do not let it touch metal. Testing the Power Connections Temporarily connect: The 14-wire harness into the stereo's 14-pin wiring socket. Your vehicle battery's negative (-) cable. Install the stereo's anti-theft control panel (see "Installing the Control Panel", below). Then turn on your vehicle's ignition. Verify that everything works properly (the stereo works properly when the display lights and the frequency or time display appears). If the stereo does not work, IMMEDIATELY TURN OFF YOUR VEHICLE'S IGNITION, THEN UNPLUG THE 14-WIRE HARNESS AND YOUR VEHICLE BATTERY'S NEGATIVE (-) CABLE. Recheck your connections. If the stereo works properly, disconnect: The 14-wire harness from the stereo's 14-pin wiring socket. Your vehicle battery's negative (-) cable. Then proceed with the installation. Connecting Speakers You can connect one or two pairs of speakers to the stereo. CAUTIONS: Be sure your speakers can handle 28 watts of power (14 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 sections. Do not use a common wire or chassis ground for any speaker connection. Connecting One Pair of Speakers If you are using only one pair of speakers, rotate FADER to its center position until you feel it click and the tab on FADER points to the left. Then follow these steps to connect the 14-wire harness to 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 violet / 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 green/black wire to the left speaker's negative terminal. Connecting Two Pairs of Speakers If you are using both front and rear speakers, follow these steps to connect the 14-wire harness to the speakers. 1. Connect the gray wire to the right front 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 front 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 front speaker's positive terminal. 4. Connect the white / black wire to the left front speaker's negative terminal. 5. Connect the violet wire to the right rear speaker's positive terminal. 6. Connect the violet / black wire to the right rear speaker's negative terminal. 7. Connect the green wire to the left rear speaker's positive terminal. 8. Connect the green / black wire to the left rear speaker's negative terminal. Connecting the Antenna Connect the vehicle's antenna cable to the stereo's large, black antenna jack. Testing the Installation CAUTION: Make sure you have securely made all connections before continuing with the installation. Plug the 14-wire harness into the 14-pin wiring socket, then reconnect the cable to the vehicle battery's negative terminal. Turn on your vehicle's ignition and test the stereo. If the stereo does not work, IMMEDIATELY TURN OFF YOUR VEHICLE'S IGNITION, THEN DISCONNECT THE 14-PIN WIRING HARNESS FROM THE STEREO'S 14-PIN WIRING SOCKET AND YOUR VEHICLE BATTERY'S NEGATIVE (-) TERMINAL. Recheck your connections. After you test the stereo and verify that everything works, make sure the connections are correctly marked or identified.
