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.
