English
If #10 screws are used, mark hole locations, and drill
holes using #18 or 11/64” drill bit.
1. Loosen both button head screws on the mounting
bracket. Now, tachometer can tilt back and forth (see
figure 3).
2. Install #10 screws (see figure 3).
3. Slide the Shift Light around the tachometer to desired
position (see figure 4).
4. Tighten both button head screws on the mounting
bracket (see figure 4).

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 the cylinder setting before installation. The
Cylinder Selector Switch is located on the back of the
tachometer, behind the door (see figure 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 System)
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 ELECTRICAL CONNECTIONS), connect 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 cylinders 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 suggested that the tachometer be electrically
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. Confirm the operation of the
tachometer. Disconnect tachometer.
MOUNTING THE TACHOMETER
Your tachometer is designed to be mounted on any
flat or curved surface, or on the steering column (see
figure 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
fire extinguisher handy. A 5-lb or larger CO2 or dry
chemical unit specified for gasoline/chemical/electrical
fires 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 dirt flying 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
avoid asphyxiation, always operate vehicle 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 firmly set.
Avoid contact with hot surfaces such as exhaust
manifolds and pipes, mufflers (catalytic converters),
radiator and hoses.
Never smoke while working on your vehicle. Gasoline
vapor is highly flammable, and the gas formed in a
charging battery is explosive.
Do not lay tools or equipment on the battery.
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.
