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.  
Required Tools  
You'll need a screwdriver, a 1.5 volt AA battery  
and the following:  
12 V DC  
TEST BULB  
ELECTRICAL SIDE-CUT  
TAPE PLIERS  
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.

THICKNESS  
MIN. 3/16" (4.75 mm)  
MAX. 7/32" (5.56 mm)  
Now turn the ignition off and then on. If the bulb  
also turns off and on, that outlet is the vehicle  
power lead.  
2-3/32" (53 mm)  
If your vehicle 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).  
7-5/32" (182mm)  
Battery Lead  
If your stereo unit has a yellow lead, you will  
need to locate the vehicle's battery lead.  
Otherwise you may ignore this procedure. (The  
yellow battery lead provides continuous power to  
maintain a clock, memory storage or other  
function.)  
Identify All Leads  
The first step in installation is to identify all the  
vehicle wires you'll use when hooking up your  
sound system.  
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.  
If your vehicle has a radio or is pre-wired for one:  
With the ignition and headlights off, identify the  
vehicle 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.  
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.  
If your vehicle is not wired for an audio unit:  
Go to the fuse block and find the fuse port for the  
battery, usually marked BAT.  
Power Lead  
If your vehicle has a radio or is pre-wired for one:  
Speakers  
Identify the vehicle speaker leads. There will be  
two leads for each speaker, usually color coded.  
20  
Download from Www.Somanuals.com. All Manuals Search And Download.  
Installation Guide (continued)  
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.  
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.  
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 holding 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.  
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.  
Antenna  
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.  
The antenna lead is a thick, black wire with a  
metal plug at the end.  
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.  
Connect All Leads  
Now that you have identified all the wires in the  
vehicle, youre ready to begin connecting them to  
the stereo unit wires. The connection diagram on  
Page 26, 27 show the proper connections and  
color coding of the leads.  
We strongly recommend that you test the unit  
before making a final installation.  
CORRECT  
You can set the unit on the floor and make  
temporary connections to test the unit. Use  
electrical tape to cover all exposed wires.

Battery  
Final Installation  
Connect the yellow battery lead to the correct  
radio wire or to the battery fuse port on the fuse  
block.  
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. Now insert the stereo unit  
into the mounting collar.  
Antenna  
Connect the antenna by plugging the antenna  
lead into the antenna receptacle.  
Congratulations! After making a few final checks,  
you're ready to enjoy your new auto stereo  
system.  
Equipment  
Connect any optional equipment such as  
amplifier, 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  
installation instructions for any equipment you  
will connect to this unit.
