Panasonic CQR255SEUC - Manual (Page 23)

□ Required Tools
You’ll need a screwdriver, a 1.5 volt AA battery, and
the following:
12 V DC
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.
□ Dashboard Specifications
THICKNESS
MIN. 3/16" (4.75 mm)
■—rjj:--- MAX. 7/32"
2-3/32" (53 mm
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 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).
□ 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.
Power Lead
If your vehicle has a radio or is pre-wired for one :
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.
