□ Connect All Leads
Now that you have identified ail the wires in the
vehicle, you're ready to begin connecting them
to the stereo unit wires. The connection dia¬
gram (■* Page 30 or 31) shows the proper con¬
nections 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
temporary 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
connections.
Ground
Connect the black ground lead of the power
connector to the metal vehicle chassis.
Speakers
Connect the speaker wires. See the wiring dia¬
gram
Page 30 or 31) for the proper
hookups. Follow the diagram carefully to avoid
damaging the speakers and the stereo unit.
The speakers used must be able to handle
more than 40 watts of audio power. If using an
optional audio amplifier, the speakers should
be able to handle the maximum amplifier out¬
put power. Speakers with low input ratings can
be damaged. Speaker impedance should mea¬
sure 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 insulated wires. If in doubt about how
your car's speakers are wired, please consult
with your nearest professional 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 am¬
plifier, according to the instructions furnished
with the equipment. Keep about 12 inches
(30 cm) of distance between the speaker
cords/amplifier unit and the antenna/antenna
extension cord. Read the operating and instal¬
lation instructions for any equipment you will
connect to this unit.
Power
Connect the red power lead to the correct vehi¬
cle 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 proceed to the final installation.
□ Final Installation
Lead Connections
Connect all wires, making sure that each con¬
nection 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 con¬
nected 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
proper operation.
If you have difficulties, consult your nearest au¬
thorized professional installer for assistance.
