UNIVERSAL INSTALLATION
1. Inspect the Existing Radio Opening
A. Use the trimplate supplied with the radio to cover the existing dashboard opening. If it completely
covers the opening, you can install the radio without an installation kit. If it does not cover the
opening, you will need an installation kit.
B. Check that there will be sufficient space behind the dashboard for the radio chassis.
2. Wire the Radio to the Vehicle's Wiring
A. In most cases, it is easier to wire the radio before mounting it. Place the radio near the dashboard
so the wires can be led through the opening.
B. Carefully follow the wiring diagram in this manual and make certain all connections are secure and
insulated with wire nuts or electrical tape to insure proper operation of the unit.
C. After completing the wiring, turn the unit on to confirm operation (ignition switch must be "on"). If
unit does not operate, re-check all wiring until the problem is corrected. Once proper operation is
achieved, turn off unit and ignition switch, and proceed with final mounting of the radio.
3. Mounting the Radio
A. Thread a shaft nut half-way down each radio shaft.
B. Place a metal back-up plate on each radio shaft against the shaft nut.
C. Position the radio behind the dashboard opening so that the back-up plates are snug against the
back of the opening. Adjust the shaft nuts behind the back-up plates so that the desired amount
of radio nosepiece extends through the opening. The best appearance is usually achieved when
there is just enough of the radio extending to be flush with the front of the trimplate.
D. Place the trimplate over the front of the radio and secure it with a shaft nut on each radio shaft.
E. Attach one end of the perforated support strap (supplied) to the screw stud on the radio using the
hex nut provided. Bend the strap to position it as necessary.
CAUTION: The rear of the radio must be supported with the strap to prevent damage to the dashboard
from the weight of the radio or improper operation due to vibration.
F. Install knobs on the radio.
