Now that you have identified all the wires in the car,
you're ready to begin connecting them to the stereo
unit wires. The connection diagram (

B

Page 46,

47) shows 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 connections.

Ground
Connect the black ground lead of the power connec-
tor to the metal car 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
37 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 car 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 an amplifi-
er, according to the instructions furnished with the
equipment. Leave about 12 inches (30 cm) of dis-
tance between the speaker cords/amplifier unit and
the antenna/antenna extension cord. Read the oper-
ating and installation instructions of any equipment
you will connect to this unit.

Power
Connect the red power lead to the correct car 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 with white stripe) to accessory
(ACC).

Lead Connections
Connect all wires, making sure that each connection
is insulated and secure. Bundle all loose wires and
fasten them with tape so they won't fall down later. 

Congratulations!  After making a few final checks,
you’re ready to enjoy your new auto stereo system.

❏

1. Make sure that all wires are properly connect-

ed and insulated.

2. 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.

The first step in installation is to identify all the car
wires you’ll use when hooking up your sound sys-
tem.
As you identify each wire, we suggest that you label
it using masking tape and a permanent marker. This
will help avoid confusion when making connections
later. 

Note: Do not connect the power connector to the
stereo unit until you have made all connections. If
there are no plastic caps on the stereo hooking
wires, insulate all exposed leads with electrical tape
until you are ready to use them. Identify the leads in
the following order.

Power Lead
If your car has a radio or is pre-wired for one :
Cut the connector wires one at a time from the plug
(leaving the leads as long as possible) so that you
can work with individual leads.

If your car has a radio or is pre-wired for one:
With the ignition and headlights off, identify the car
battery lead by grounding one lead of the test bulb
to the chassis and checking the remaining exposed
wires from the cut radio connector plug.

If your car is not wired for an audio unit : 
Go to the fuse block and find the fuse port for the
battery, usually marked BAT.

Speakers
Identify the car speaker leads. There will be two
leads for each speaker, usually color coded.
A handy way to identify the speaker leads and the
speaker they connect with is to test the leads using
a 1.5 volt AA battery as follows.
Hold one lead against one pole of the battery and
stroke the other lead across the other pole. You will
hear a scraping sound in a speaker if you are hold-
ing a speaker lead.
If not, keep testing different lead combinations until
you have located all the speaker leads. When you
label them, include the speaker location for each.

Antenna Motor
If your car is equipped with an automatic power
antenna, identify the car motor antenna lead by con-
necting one bulb tester lead to the car battery lead
and touching the remaining exposed wires from the
cut radio connector plug one at a time. You will hear
the antenna motor activate when you touch the cor-
rect wire.

Antenna
The antenna lead is a thick, black wire with a metal
plug at the end.

Turn the ignition on to the accessory position, and
ground one lead of the test bulb to the chassis. 

Touch the other lead of the test bulb to each of the
exposed wires from the cut radio connector plug.
Touch one wire at a time until you find the outlet that
causes the test bulb to light. 

Now turn the ignition off and then on. If the bulb also
turns off and on, that outlet is the car power lead. 

If your car is not wired for an audio unit : 
Go to the fuse block and find the fuse port for radio
(RADIO), accessory (ACC), or ignition (IGN).

Battery Lead
If your stereo unit has a yellow lead, you will need to
locate the car's battery lead. Otherwise you may
ignore this procedure. (The yellow battery lead pro-
vides continuous power to maintain a clock, memory
storage, or other function.)
