GENERAL INFORMATION
Thank you for your purchase of K&C Harrison INC. product!
Owner-Installer, please review installation and instructions in owner’s manual.
Keep in mind that your radio and/or speakers are custom equipment: designed
specifically for your year vehicle. It should be handled carefully and installed preferably
by an auto radio specialist. We suggest that you “Bench Test” the unit before
installation, as we do, before shipping. Therefore if a careless installation occurs, such
as “Frying the circuit” or possibly other damages, the installer is responsible. Shipping
damage occasionally does occur.
PLEASE READ THE OWNER’S MANUAL THOROUGHLY BEFORE
USING YOUR RADIO.
IT IS RECOMMENED THAT YOU DISCONNECT THE BATTERY’S
NEGATIVE LEAD BEFORE INSTALLING ANY ELECTRONIC EQUIPMENT
IN YOUR VEHICLE. RE-CONNECT WHEN WIRING IS COMPLETE.
First you will need to remove the original knobs, bezels and shaft nuts. Unplug
the main wire harness and speaker leads from the back of the radio.
Disconnect antenna lead and remove mounting strap from the back of the radio.
The radio is now ready to be removed from the dash.
Please refer to wiring instructions on pages 5 and 6.
Plug in antenna lead. On speaker leads, make sure the positive lead goes to positive
terminal and negative lead to negative terminals of speakers. A minimum of two
speakers are required for this stereo radio. DO NOT CONNECT ANY TWO SPEAKER
LEADS TO EACH OTHER OR THE VEHICLE GROUND.
Plug in or wire the red power wire to an ignition controlled power supply. Plug in
or wire the orange wire to the battery terminal or to any constant 12-volt power
supply. We recommend not using any of the original radio power wires.
A sound well-grounded antenna is important for optimum function, as well
as correctly wired speakers.

POWER /SPEAKER CONNECTION (REFER TO FIG. 1 PAGE 6)
A. RED WIRE (IGNITON)
Connect the RED wire to an accessory fuse that switches OFF when the key
is in the OFF position. (This does not apply to vehicles with 6 volt or positive
ground systems)
B. ORANGE WIRE (BATTERY)
Connect the orange wire to an accessory fuse that is always ON regardless
of the position of the ignition key. This lead supplies power to the program
memory and clock circuit when the radio is switched off. (This does not apply
to vehicles with 6 volt systems or positive grounds systems)
C. SPEAKER WIRES
Connect the speaker wires as shown in Figure 1on page 6. Do not connect
speaker wires to each other or the vehicle ground. If only two speakers are
used, be sure the leads for the rear speakers are taped off to prevent them
from shorting out.
D. YELLOW WIRE (AUTO ANTENNA)
This wire can be connected to the terminal of the automatic power antenna
relay (if vehicle is so equipped) or the turn on lead of an optional amplifier. It
will provide remote power on/off by using the power switch on the radio.
NOTE: DO NOT connect this wire to a ground or to an accessory that requires high
current. Doing so will burn up the on/off power switch. If your vehicle is not equipped
with an automatic antenna, tape off wire to prevent shorts.
E. BLACK WIRE (GROUND)
Connect the black ground wire terminal with a ring terminal to the metal
chassis of your vehicle. A good ground is important for the optimum
performance of your radio.

NOISE SUPPRESSION
ALL KHE systems are designed for maximum electrical noise rejection. However, in
some installations electrical noise my affect the quality of sound production. The
procedures described under NOISE SUPPRESSION-INSTALLATION are best applied
even if no interference is present. If noise is present after installing the KHE series,
identify the source of the noise using the description under SOURCES OF
ELECTRICAL NOISE. To eliminate the noise, follow the procedures described under
SOLUTIONS of the specific noise source.
NOISE ELIMINATION
B Check all ground connection. If the KHE series is mounted on plastic, be sure there
is a heavy gauge ground lead connecting the unit to a solid chassis
10

ground. Scrape paint away from painted surface to secure a good
electrical ground.
C. Check battery posts. If contacts are corroded or loose, clean and tighten
both terminals.
D. Check battery or add fluid.
E. Check condition of spark plug and distributor leads. Worn or damaged
leads will generate noise that can be very difficult to eliminate.
F. Check installation of factory noise suppressor(s). Verify that the connections are
solid. Refer to the vehicles service manual for noise suppressor location or allow a
qualified mechanic to inspect the device(s) for you.
G. (Optional) Some professional installers will install a simple L.C. noise filter even if
there is no noise present in the system. This is a simple and relatively inexpensive
device available at your nearest auto-sound dealer or electronic supply store. Most
filters designed for car stereos carry a current rating
of 5 AMPS. Follow the manufacturer’s installation instructions. This filter
is installed in the power line of the car stereo.
SOURCES OF ELECTRICAL NOISE
ALTERNATOR NOISE
A light-pitched whine present with the engine running. The pitch of the whine
will vary as engine specifications vary. Alternator noise usually becomes more
apparent with an electrical load to the system. Switching the headlights on
usually accentuates the noise.
SOLUTIONS
C. Install a L.C. noise filter (available from your auto-sound dealer or your
nearby electronic or automotive supply store.) in the power line of the KHE
series. This filter should be rated at 4 AMPS.
D. Start the car’s engine, turn on the light (to accentuate the noise), and turn
on the KHE series. If noise is still present proceed to step 3.
E. Install an alternator noise filter (available from your auto-sound dealer or
your nearby electronic or automotive supply store). Follow manufacturer’s
installation instructions.
ANTENNA NOISE
A static crackle heard through the speakers, usually when the car is running,
but sometimes present with the ignition off. If a crackling static is present,
follow the steps outlined below to confirm the antenna is the cause of noise.
C. Start the car engine.
D. Turn on the KHE series.
E. Adjust volume so that noise is audible.
F. Reduce volume setting of the car stereo, but do not switch the unit off. If
noise decreases, the signal is most likely being picked up by the car
antenna. If the noise persists after following the steps listed below, proceed
to IGNITION NOISE.
SOLUTIONS
4. Remove the nut securing the antenna to the fender or body of the car.
11

2. Remove any washers or spacers, remembering the way in which they
were removed.
3. Scrape away rust or paint below the fender to insure a good electrical
connection. Do not scrape the paint on the outside surface of the fender
or you will invite rusting of the body metal.
4. Test the antenna lead for any breaks or shorts. Signs of crimping, kinking
or fraying usually indicate damage to the cable. Replace the antenna or
cable if necessary.
IGNITION NOISE
A popping or cracking noise heard through the speakers. The noise will vary as the
engine RPM varies. The noise will only be present with the engine running.
ELIMINATION
1. Install an L.C. Filter Network in the power lead of the KHE series. The
filter should be rated at 4 AMPS.
2. Inspect spark plug and distributor cable for signs of wear or damage.
Replace as necessary using resistor cable only. Metal conductor ignition
cables increase static interference.
NOTE: Do not use spark plug or distributor noise filter as these can create
more problems than they solve. They decrease the quality of spark generated
by the spark plugs and they may create more static than they eliminate.
ALTERNATOR NOISE
A popping heard when the light, turn indicators, windshield wipers, cigarette
lighter, etc., are turned on. This indicates a vehicle wiring deficiency. Most
occurrences are minor and present no risk to the stereo system other than the
annoyance of the listener. However, severe cases may damage the speakers,
minor occurrences can be remedied. Severe occurrences must be taken care of
by a professional as they present a threat to not only the stereo system, but to
the vehicle wiring itself.
ELIMINATION
1. Install an L.C. filter network in the power lead of the KHE series.
2. If the noise persists, consult a professional automotive service technician.
NOTICE: Repairs, warranty or non-warranty can only be accomplished by K&C
Harrison INC. DO NOT RETURN product to other dealers or distributors. In the
interest of time saving, please call our technicians if problems are questionable.
Radios and other products that are damaged in any way, disassembled, or with
cut wiring are not covered by warranty. Minor operational troubles and incorrect
wiring are often mistaken for a breakdown. Check the following points before
having your unit repaired.
