□ Connect All Leads
Now that you have identified all the wires in the
vehicle, you're ready to begin connecting them to
the stereo unit wires. The connection diagram on
Page 52 show the proper connections and color
coding of the leads.
We strongly recommend that you test the unit
before making a final installation.
You can set the unit on the floor and make tempo­
rary connections to test the unit. Use electrical tape
to cover all exposed wires.
IMPORTANT : Connect the red power lead last,
after you have made and insulated all other connec­
tions.
Ground
Connect the black ground lead of the power con­
nector to the metal vehicle chassis.
Speakers
Connect the speaker wires. See the wiring diagram
below for the proper hookups. Follow the diagram
carefully to avoid damaging the speakers and the
stereo unit.
The speaker used must be able to handle more
than 30 watts of audio power. If using an optional
audio power, the speakers should be able to handle
the maximum amplifier output power. Speakers
with low input ratings can be damaged.
Speaker impedance should measure 4 - 8 ohms,
which is typically marked on most speakers. Lower
or higher impedance speakers will affect output and
can cause both speaker and stereo unit damage.
CAUTION : Never ground the speaker cords. For
example, do not use a chassis ground system or a
three-wire speaker common system. Each speaker
must be connected separately using parallel insulat­
ed wires. If in doubt about how your car's speakers
are wired, please consult with your nearest profes­
sional installer.
Motor Antenna
Connect the vehicle motor antenna lead to the blue
motor antenna relay control lead.
Battery
Connect the yellow battery lead to the correct radio
wire or to the battery fuse port on the fuse block.
Antenna
Connect the antenna by plugging the antenna lead
into the antenna receptacle.
Equipment
Connect any optional equipment such as amplifier,
according to the instructions furnished with the
equipment. Keep about 12 inches (30 cm) of dis­
tance between the speaker cords/amplifier unit and
the antenna/antenna extension cord. Read the
operating and installation instructions for any equip­
ment you will connect to this unit.
Power
Connect the red power lead to the correct vehicle
radio wire or to the appropriate fuse port on the fuse
block.
If the stereo unit functions properly with all these
connections made, disconnect the wires and pro­
ceed to the final installation.
Illumination
1 .Connect to light switch, the control button are illu­
minated.
2.Can not find the light switch, connect the illumina­
tion lead (orange lead) to accessory (ACC).
□ Final Installation
Lead Connections
Connect all wires, making sure that each connec­
tion is insulated and secure. Bundle all loose wires
and fasten them with tape so they won't fall down
later. Now insert the stereo unit into the mounting
collar.
Congratulations! After making a few final checks,
you’re ready to enjoy your new auto stereo system.
□ Final Checks
1. Make sure that all wires are properly connect­
ed and insulated.
2. Make sure that the stereo unit is securely held
in the mounting collar.
3. Turn on the ignition to check the unit for prop­
er operation.
If you have difficulties, consult your nearest autho­
rized professional installer for assistance.
