Step 1:
The radio chassis is designed to be “Sleeve
Mounted” through a opening in the dashboard panel.
The required opening size is 182mm (7-3/16”) x
52mm (2-1/16”). Cut or enlarged an opening in the
dashboard to accommodate the mounting sleeve.
Step 2:
If you are replacing an existing factory
installed radio, an adapter harness might be avail-
able for your vehicle to eliminate the need for
cutting your factory wiring. Contact Radio Shack
or other car stereo installation centers for the avail-
ability of a harness for your vehicle.
Step 3:
Insert the mounting sleeve into the hole in
the dashboard. Bend the metal tabs on the sleeve to
secure the mounting sleeve to the dashboard.
Step 4
: Bring all wiring for the connection of the
unit (including the antenna) through the center of the
mounting sleeve. Connect the wiring as follows:
Yellow Wire: Connect this wire to a constant +12
volt power source (a power source that is not con-
trolled by the ignition key).
Red Wire (with Fuse): Connect this wire to a
switched +12 volt power source (a power source
turned on and off by the ignition key).
Blue Wire: Connect this wire to the (+) power
antenna activation circuit or remote amplifier acti-
vation. If no power antenna or amplifier exists,
tape-off the end of this wire to prevent shorting
out the unit.
Black Wire: Connect this wire to the frame of the
vehicle (ground). This wire is the chassis grounding
wire for the unit.
White Wire: Connect this wire to the Left Front
Speaker (+) positive terminal or wire.
White Wire with Black Stripe: Connect this wire to the
Left Front Speaker (-) negative terminal or wire.
Green Wire with Black Stripe: Connect this wire to the
Left Rear Speaker (-) negative terminal or wire.
Green Wire: Connect this wire to the Left Rear
Speaker (+) positive terminal or wire.
Gray Wire: Connect this wire to the Right Front
Speaker (+) positive terminal or wire.
Gray Wire with Black Stripe: Connect this wire to the
Right Front Speaker (-) negative terminal or wire.
Purple Wire with Black Stripe: Connect this wire to
the Right Rear Speaker (-) negative terminal or wire.
Purple Wire: Connect this wire to the Right Rear
Speaker (+) positive terminal or wire.
Brown Cable with Red/White RCA Connectors:
Provides Left and Right Channel audio signal output
