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

gure 3).

2. Install #10 screws (see gure 3).

3. Slide the Shift Light around the tachometer to desired

position (see gure 4).

4. Tighten both button head screws on the mounting

bracket (see gure 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 gure 1). The Factory

Setting is 8 Cylinders. Change the setting if necessary.

DISTRIBUTOR EQUIPPED ENGINES

Set the switch to match the number of cylinders in the

engine.

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. Conrm the operation of the

tachometer. Disconnect tachometer.

MOUNTING THE TACHOMETER

Your tachometer is designed to be mounted on any

at or curved surface, or on the steering column (see

gure 2).

INSTALLATION INSTRUCTIONS

GENERAL INFORMATION

Please read this instruction manual and review the

installation procedures carefully before attempting the

installation of your tachometer.

CAUTION

This unit is designed for use on 12-volt negative (-) ground

4-cycle automotive type engines. The tachometer is

compatible with most distributor and distributorless

ignition systems.

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 specied 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 dirt 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

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 rmly set.

Avoid contact with hot surfaces 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 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.
