SAFETY GUIDELINES
Topreventaccidentsthatcouldresultinseriousinjuryand/
or damage to your vehicle or tachometer, carefully follow
these safety rules and test procedures.
Wear safety goggles when working on your vehicle.
A l w a y s o p e r a t e v e h i c l e i n 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.
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 the tachometer.
INSTALLING MOUNT BRACKET
Your tachometer is designed to be mounted on any
at or curved surface, or on the steering column
using the clamp kit.
Steering Column Mounting
1. Assemble steering column bracket (5) and cup (1)
using male nut (3) and female nut (2). Tighten male
nut only enough to still allow cup to be positioned to
proper angle.
2. Wrap rubber strip (9) around steering column.
3. Place assembled cup and column bracket on rubber
strip and secure to steering column with adjustable
clamp (8).
Instrument Panel Mounting
1. Select best possible mounting location for good vis-
ibility from a normal driving position.
2. Mounting bracket (4) can be used for a marking or
drill template.
3. Drill two 3/16” holes for #8 screws, lock washer and
nuts or two 5/32” holes for #8 self-tapping screws.

CAUTION
For your own personal safety, and to prevent possible
damage to the electrical system of your vehicle during
the installation,disconnectthenegative (-)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 in the rewall for the grommet (included).
1. Attach wires to tachometer as required.
NOTE: Use # 18 or # 20 AWG stranded automotive
primary wire.
2. Thread wires through female nut (2), cup (1), bracket
(4 or 5) and male nut (3). Note: At this point, items 1,
2, 3 and 4 or 5 should have been preassembled.
3. Leave tachometer out of the cup for now.
SIGNAL POST CONNECTION AND CYLINDER
SELECTION
The Cylinder SelectorSwitch is located on theback of the
tachometer. The factory setting is 8-cylinders. Change
the setting if necessary.
The 4, 6, 8, and 10-cylinder settings are most common
for all distributor equipped engines and Distributorless
Ignition Systems (DIS) with a tachometer output lead.
The2-cylindersettingisdesignedfor2-cylinderenginesand
DIS systems without a tachometer output lead that allow
access to the driver wires from the vehicle computer
to the ignition module.
The 1-cylinder setting is used with single cylinder engine
vehicles and in conjunction with the CP7560 Tach Signal
adapter.
The CP7560 Tach Signal Adapter (sold separately)
senses current pulses in the wire that supplies +12 volts
to the ignition coil primary windings or fuel injector and
converts the pulses to a signal that is understood by the
tachometer.The CP7560TachSignalAdapteris required
toconnectthetachometertoCoilOnPlugignitionsystems
and to diesel engines with electronic injection.
DISTRIBUTOR EQUIPPED ENGINES
Connect the SIGNAL tachometer post to the negative
(-) side of the ignition coil. This terminal may be referred
to as the TACH, TACH TEST, DEC, or ECU terminal.
Set the Cylinder Selection switch on the back of the
tachometer to match the number of cylinders in the
engine.
DISTRIBUTORLESS IGNITION SYSTEM EQUIPPED
ENGINES WITH A TACHOMETER OUTPUT LEAD
Connect the SIGNAL tachometer post to the vehicle‘s
tachometer output lead.
Set the Cylinder Selection switch on the back of the
tachometer to match the number of cylinders in the
engine.
DISTRIBUTORLESS IGNITION SYSTEM EQUIPPED
ENGINES WITHOUT A 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,
connect the SIGNAL tachometer post to one of the
driver wires.
Set the Cylinder Selection switch on the back of the
tachometer to the 2-cylinder position regardless of
the number of cylinders in the engine.
MULTIPLE SPARK DISCHARGE IGNITION SYSTEM
EQUIPPED ENGINES
For Multiple Spark Discharge ignition systems, connect
the SIGNAL tachometer post only to the tachometer
output terminal on the ignition module. Do NOT connect
to the ignition coil.
Set the Cylinder Selection switch on the back of
the tachometer to match the number of cylinders
in the engine.
COIL ON PLUG IGNITION SYSTEM EQUIPPED
ENGINES
To connect the tachometer to these engines you need
to purchase the CP7560 Tach Signal adapter. Follow
instructions included with the adapter to hook up wires
and to set the Cylinder Selection switch.
DIESEL ENGINES WITH ELECTRONIC INJECTION
To connect the tachometer to these engines you need to
purchase the CP7560 Tach Signal adapter. Follow instruc-
tions included with the adapter to hook up wires and to set the
Cylinder Selection switch.
-12V DC GROUND, +12V DC POWER, AND 12V
DC LAMP POST CONNECTIONS
ALL VEHICLE SYSTEMS
1. Connect the post labeled -12V DC GROUND to the
negative (-) battery terminal, or a clean unpainted
chassis ground using a ring terminal or other suit-
able means.
2. Connect the post labeled +12V DC POWER 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.
3. Connect the post labeled 12V DC LAMP to the
instrument panel lighting circuit that is controlled by
the instrument panel dimmer control.
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 12V DC LAMP post to a circuit which is
energized by the headlamp switch.
INSTALLING TACHOMETER IN CUP
1. Place tachometer in cup. Gently pull wires out, so
they would not be jammed between the cup and
tachometer.
2. Secure tachometer in cup using #8 lock washers
(6) and #8-32 acorn nuts (7). Turn acorn nuts down
nger-tight and, with a wrench or nut driver, tighten an
additional 1/2 turn. DO NOT OVER TIGHTEN.
3. Position cup as desired and tighten male nut (3).
