WIRING HARNESS

For easier installation, the supplied 13-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.

Caution:  For added safety and to protect your stereo, disconnect the
          cable from the negative(-) terminal on your vehicle's battery
          before you begin installation.

CONNECTING SPEAKERS

Any speakers you connect to the stereo must have a combined power-
handling capacity of at least 30 watts, and each individual speaker must
have an impedance of at least 4 ohms.  Your local Radio Shack store
carries a full line of automotive speakers.

Caution:  You must connect a separate wire to each speaker terminal as
          described in the following procedures.  Do not use a common
          wire or chassis ground for any speaker connection.

Connecting Two Speakers

If you are using only one pair of speakers, set 4 CH/2CH on the bottom of
the stereo to 2CH.  Then connect the speakers to the supplied harness as
follows.

1.  Connect the harness' gray wire to the right speaker's positive (+)
    terminal.

2.  Connect the harness' violet wire to the right speaker's negative (-)
    terminal.

3.  Connect the harness' white wire to the left speaker's positive (+)
    terminal.

4.  Connect the harness' green wire to the left speaker's negative (-)
    terminal

5.  Tie off the unused wires for the rear speakers.

Connecting Four Speakers

If you are using both front and rear speakers, set 4CH/2CH on the bottom
of the stereo to 4CH.  Then connect the speakers to the supplied harness
as follows.

1.  Connect the harness' gray wire to the front-right speaker's positive
    (+) terminal.

2.  Connect the harness' gray/black wire to the front-right speaker's
    negative (-) terminal.

3.  Connect the harness' violet wire to the rear-right speaker's positive
    (+) terminal.

4.  Connect the harness' violet/black wire to the rear-right speaker's
    negative (-) terminal.

5.  Connect the harness' white wire to the front-left speaker's positive
    (+) terminal.

6.  Connect the harness' white/black wire to the front-left speaker's
    negative (-) terminal.

7.  Connect the harness; green wire to the rear-left speaker's positive
    (+) terminal.

8.  Connect the harness' green/black wire to the rear-left speaker's
    negative (-) terminal.

CONNECTING TO OTHER COMPONENTS

You can connect other audio components (such as an equalizer/booster or
amplifier) to your stereo's speaker or line level outputs.  Check the
component's owner's manual for instructions on connecting it to a stereo
and to power.

If you want to turn the optional component on and off with the stereo,
connect the stereo's blue wire (labeled SWITCHED POWER LEAD) to it.  This
wire does not provide power to the component.  It simply turns it on or
off.  If you do not use this wire, use a wire tie to keep it out of the
way.

Note:  The optional component must be designed for use with a switched
       power lead for the above connection.  See the optional component's
       owner's  manual.

CONNECTING TO POWER AND YOUR VEHICLE'S ANTENNA

1.  Connect the stereo's black ground wire to a metal screw attached to
    the vehicle's frame.  Be sure the screw is not insulated from the
    chassis by a plastic part.

2.  Connect the stereo's yellow wire (with an in-line fuse holder and
    MEMORY BACKUP LEAD label) to your battery's positive (+) terminal or
    to a non-switched fuse terminal (a terminal that the vehicle's
    ignition does not turn on and off).  This connection provides
    12-volts of continuous power for the tuner memory and the security
    LED when the ignition is turned off.

3.  Connect the stereo's solid red power wire (with an in-line fuse
    holder) to the accessory (ACC) terminal on your vehicle's fuse block.

This connection provides power to the stereo when you turn on the
ignition, and turns off power when you turn off the ignition.  This
prevents your vehicle's battery from draining if you leave the stereo on
when you turn off the ignition.

4.  Connect the vehicle's antenna cable to the stereo's large black
    antenna connector.

5.  Connect the stereo's orange/white wire (labeled DISPLAY LIGHTING) to
    the switched side of either your headlamp/parking light circuit or the
    accessory switch.  This connection provides power to the display's
    backlighting.

6.  Connect the supplied harness to the socket on the back of the stereo.
    When all connections are complete, reconnect the battery cable.

TESTING THE CONNECTIONS

After you connect the speakers, power wires, and antenna, turn on your
vehicle's ignition to test the stereo and be sure it works.

If your stereo does not work, immediately unplug the wiring harness.
Recheck your connections or have a professional complete the installation.

If the stereo works, follow the instructions under "Installing/Removing
the Stereo."
