TEST BULB
ELECTRICAL
TAPE
SIDE-CUT
PLIERS
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.
Turn the ignition on to the accessory position, and ground one lead of the test bulb to the chassis.

□ Identify All Leads

The first step in installation is to identify all the vehi cle 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.
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 as follows.
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 vehicle power lead.
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).
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, memo ry storage, or other function.)
If your vehicle 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 vehicle 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.

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.
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 vehicle is equipped with an automatic power
antenna, identify the vehicle motor antenna lead by connecting one bulb tester lead to the vehicle bat tery 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 correct wire.
Antenna
The antenna lead is a thick, black wire with a metal
plug at the end.

□ 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 29 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 40 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.
