ELECTRICAL CONNECTIONS
CAUTION
For your own personal safety, and to prevent possible
damage to the electrical system of your vehicle during
the installation, disconnect the negative (-) battery cable.
Reconnect this cable after installation is complete.
Do not route wires along or against sharp edges, hot
engine surfaces, or near spark plug wires. If needed, drill
a 3/8” hole for the grommet (included).
NOTE: If additional wire is needed, use #18 or #20 AWG
stranded automotive primary wire.
High voltage — 30,000 to 50,000 volts — is present in
the ignition coil, distributor cap, ignition wires and
spark plugs. When handling ignition wires while the
engine is running, use insulated pliers to avoid a shock.
While not lethal, a shock may cause you to jerk
involuntarily and hurt yourself.
Never crawl under vehicle or run engine while vehicle
is on a jack.
CYLINDER SELECTION
Check t he c ylinder setting before installat ion. T he
Cylinder Selector Switch is located on the back of the
tachometer, behind the door (see gure 1). The Factory
Setting is 8 Cylinders. Change the setting if necessary.

DISTRIBUTORLESS IGNITION SYSTEM
EQUIPPED ENGINES
The tachometer-ignition connection for some 4 Cylinder
and 6 Cylinder DIS (Distributorless Ignition S ystem)
engines requires that you use the 2 Cylinder setting.
Depending on which type of system you have, set the
switch as follows:
If your vehicle’s DIS ignition system has a tachometer
output lead set the switch to the 4 Cylinder position for the
4 cylinder engines and to the 6 Cylinder position for the
6 cylinder engines. When connecting tachometer wires
(see EL ECTRICA L CO NNEC T I ONS), conn e ct the
tachometer GREEN wire to the vehicle’s tachometer
output lead.
If your vehicle’s DIS ignition system does not have a
tachometer output lead but allows access to the driver
wires from the vehicle computer to the ignition module,
set the switch to the 2 Cylinder position regardless of the
number of cylinder s in the engine. When connecting
tachometer wires (see ELECTRICAL CONNECTIONS),
connect the tachometer GREEN wire to either of the
driver wires.
FUNCTIONAL QUICK CHECK
It is sug geste d that the tach ometer be ele ctr ica ll y
connected to the vehicle, (using alligator clip leads or
other suitable means) following the steps below, and an
electrical functional check of the tachometer be made,
prior to making a permanent installation.
Start the vehicle’s engine. Conrm the operation of the
tachometer. Disconnect tachometer.
MOUNTING THE TACHOMETER
Your t achometer is designed to be mounted on any
at or curved surface, or on the steering column (see
gure 2).

SAFETY GUIDELINES
To prevent accidents that could result in serious injury and/
or damage to your vehicle or tachometer, carefully follow
these safety rules and test procedures.
Fire Extinguisher
Never work on your vehicle without having a suitable
re extinguisher handy. A 5-lb or larger CO2 or dry
chemical unit specied for gasoline/chemical/electrical
res is recommended.
Safety Goggles
We recommend wearing safety goggles when working
on your vehicle, to protect your eyes from battery acid,
gasoline, and dust and dir t ying off moving engine
parts.
Be very careful not to get your hands, hair or clothes
near any moving parts such as fan blades, belts and
pulleys or throttle and transmission linkages. Never wear
neckties or loose clothing when working on your
vehicle.
Never wear wrist watches, rings or other jewelry when
working on your vehicle. You’ll avoid the possibility
of catching on moving parts or causing an electrical
short circuit which could shock or burn you.
The carbon monoxide in exhaust gas is highly toxic. To
avo id asphyxi at ion , al ways oper at e vehic le in a
well-ventilated area. If vehicle is in an enclosed area,
exhaust should be routed directly to the outside via
leakproof exhaust hose.
Make sure that your vehicle is in Park or Neutral, and
that the parking brake is rmly set.
Avoid contact with hot sur faces such as exhaust
manifolds and pipes, muf ers (catalytic converters),
radiator and hoses.
Never smoke while working on your vehicle. Gasoline
vapor is highly ammable, and the gas formed in a
charging battery is explosive.
Do no t l ay to ols o r e quipme nt on the ba t ter y.
Accidentally grounding the “HOT” battery terminal
can shock or burn you and damage wiring,the battery
or your tools and testers. Be careful of contact with
battery acid. It can burn holes in your clothing and burn
your skin or eyes.

SHIFT LIGHT L AMP REPL ACEMENT
The External Shift Light also uses a wedge base lamp
for illumination.
To replace the Shift Light lamp, follow steps to open
the shift light (see gure 10). Remove the lamp from
its socket by pulling it straight out. Replace the lamp
with a #194 automotive lamp. Reassemble the shift light by
reversing the steps.
BLACK, RED, AND WHITE WIRE CONNECTIONS
– ALL SYSTEMS
1. Connect the BLACK wire to the negative (-) battery
terminal, or a clean unpainted chassis ground using a
ring terminal or other suitable means (see gure 5.)
Make the following connections with wire splices, or
by an alternative method if desired (see gure 6.)
2. Connect the RED wire to any vehicle harness wire
which is energized with battery voltage, ONLY when the
ignition key is in the ON (RUN) position, NOT OFF OR
ACCESSORIES (see gure 5.)
3. Connect the WHITE wire to the instr ument panel
lighting circuit that is controlled by the instrument panel
dimmer control (see gure 5.)
Some vehicles (typically imported) wire the dimmer control
into the ground side of the instrument panel lighting
circuit, as opposed to the more conventional “hot” or 12-volt
side. In vehicles which use this circuit, connect the WHITE
wire to a circuit which is energized by the headlamp switch.

wires from the vehicle computer to the ignition module,
set the switch to the 2 Cylinder position regardless of the
number of cylinders in the engine. Connect the tachometer
GREEN wire to either of the driver wires.
MULTIPLE SPARK DISCHARGE IGNITION
SYSTEM EQUIPPED ENGINES
For Multiple Spark Discharge ignition systems, connect
the GREEN wire only to the tachometer output terminal on
the ignition module. Do NOT connect to the ignition coil.
SHIFT LIGHT RPM TRIP POINT SET-UP
Some possible uses for the Shift Light are:
Engine RED LINE (maximum safe operating speed of
the engine)
En g ine maximu m to r que R PM ( for m a ximu m
performance shifting) and desired shift speed.
NOTE: You will nee d both ha nds free to s et the

SUBSTITUTION OR REPLACEMENT
The t achometer is supplied with a #168 wedge base
lamp. If the light is too bright, replace with a lamp of less
intensity such as a #194 or #161.
The lamp socket is located in the rear of the housing
of the tachometer (see gure 9). To remove the lamp, gently
grasp the black lamp socket (use pliers if necessary)
and twist it c ounterc lock wise approximately 1/8 turn
until it stops. Pull the socket with lamp straight out of the
tachometer housing. Remove the lamp from its socket
by pulling it straight out. Replace the lamp. Reinstall the
socketed lamp by rotating it against the tachometer’s
internal PC board until it drops into place, and then rotate
it approximately 1/8 turn clockwise until it reaches its
mechanical stop.
