INSTALLATION
The illustration below shows the radio installation from the front of the dash. The front of your new radio is a dimensionally exact
copy of the original, so it will install the same way that the original radio did. The radio is much smaller when viewed from the back
than the original was, so the original mounting bracket won't fit. Included with your radio is a 9 inch Backstrap that can be easily cut
and bent to any shape or size. It is intended to bolt to the ¼ -20 lug on the back of the radio near the antenna jack and to the location
where the original bracket was attached. The strap will support the radio while taking some of the stress off of the control shafts. To
remove the original radio, remove the right instrument panel pad (5 Phillips screws). Disconnect the speakers and remove the
convector. Note: To remove the speakers, remove the kick pads by removing three Phillips screws. Remove three wiper switch trim
plate screws and tip the trim plate for access to the switch connector. Remove the switch connector and trim plate from the cluster
assembly. Unclip and remove the right and left console forward trim pads. Remove the forwardmost Phillips screw on both sides of
the console. Insert a flexible drive socket between the console and the metal horseshoe brace and remove the nuts from the two studs
on the lower edge of the cluster assembly. Remove the remaining four Phillips screws holding the cluster assembly in place. From the
rear, disconnect the radio electric connector, antenna plug and mounting brace. Remove the radio knobs and shaft nuts (a 9/16 deep
socket is helpful here). Pull the top of the console toward the rear of the car. Separate the radio from the console and remove it through
the right side opening.
Caution: the instrument cluster trim plate is designed to collapse on impact. Do not try to deflect the
cluster plate forward to gain more access to remove the radio. Be careful not to damage the plastic oil pressure line when
pulling the console forward!
Install the new radio by reversing the above steps.
DIAGNOSTICS
No Sound:
Check for a good fuse with proper rating. When the radio is turned on, the orange wire should have 12 volts present. Every
speaker lead should measure about 6 volts to ground with the radio on and volume low. During start up diagnostics if the radio detects
a shorted speaker wire the radio will shut off that speaker lead until the issue is resolved. Radio will mute when no station is received.
Make sure antenna is plugged into the proper jack. If an accessory is not connected there will be no audio in auxillary mode.
Weak or No Reception:
Check continuity between the center pin of the antenna plug and the antenna mast. It should read 0 ohms
(like a short) Next, check continuity between the center pin of the antenna plug and the car body. It should not read (like an open
circuit). If you’re in a metal building, reception may be limited. Try it outside.
Ignition Noise:
Usually caused by an ungrounded antenna shield. The base of the antenna must make good contact with the car body.
This problem often shows up after a good paint job! Make sure the engine grounding straps are in place, clean and tightly bonded to
the frame.
Distortion:
Check to see if your speakers can handle at least 45 watts RMS. Small speakers that can only reproduce high frequency
will distort on bass notes. Make sure speakers are properly installed. Make sure that no speaker is grounded. Every speaker lead
should measure about 6 volts to ground with the radio on and volume low. Resistance in the DC power input wiring can cause the
amplifiers to “starve”. If distortion seems to increase with volume, measure the voltage on the orange wire. If the voltage drops when
the volume is raised, it is an indication of resistance between the battery and the radio – usually at the fuse block, but sometimes in the
ignition switch. If the backstrap is not bolted to a clean metal ground, try running a heavy ground wire from the ground lug on the
radio directly to the firewall.
Radio shuts off after a few minutes:
The radio has thermal protection built in to prevent damage from excessive heat. Possible
causes are shorted or grounded speaker wires. See if any unused wires can touch anything. Make sure the heater or defroster duct isn’t
blowing directly on the radio.
Dial pointer issues:
If the dial pointer gets stuck at one end or if it is misaligned, hold down one of the preset buttons for 5-10
seconds to realign or free dial pointer. If the dial pointer is stuck at one end of the dial, turn the tuning knob. The dial pointer should
try to move while you're turning the knob. Continue to turn the tuning knob until the pointer resets itself.
BE SAFE:
Make sure you are familiar with the way this radio works before you go out on the road. Driving demands your full
attention. Texting while driving is dangerous and it is illegal in many states. Remember: not all drivers have hands free phones, so the
guy next to you may be driving while distracted.
