To prevent personal injury, damage to the vehicle and/or the tachometer, read
these instructions completely and observe the following safety precautions:

■ Always consult the vehicle's service manual and follow its safety precau-

tions before installing this gauge.

■ To prevent burns, install the tachometer only when the engine is cool.

■ The vehicle's exhaust is very toxic , to pre vent serious injury or death always

run the vehicle in a well ventilated area.

■ When an engine is running, cooling fans, pulleys, belts, etc.rotate at a very

high rate of speed.ALWAYS be aware of moving/rotating parts, and keep a
safe distance away from these items.

■ Disconnect the negative (-) battery cable before installing and/or making

tachometer connections.

NOTE:It may be necessary to reprogram your radio, clock, etc.after recon­necting the battery.

■ ALWAYS insulate wire splices with shrink tubing to prevent shorting.

Applications

This tachometer is compatible with 12 volt negative (-) ground systems ONLY,
and will work on most of the following ignition systems:

■ DISTRIBUTOR EQUIPPED - 4 cycle ignition systems

■ DISTRIBUTORLESS (DIS) and other 2 cycle Ignition Systems - these

type of systems are no longer equipped with distributors.

NOTE:This tachometer may not work on some vehicles with the following igni­tion systems:

■ Multiple Spark Ignition Systems: Consult manufacturer and/or instruc-

tions on how to connect a tachometer to these systems.

■ Direct (coil on plug) Ignition Systems: Consult the vehicle’s service

manual to determine if an adequate tachometer signal connector is avail­able for connecting an aftermarket tachometer.

■ Determine a mounting location for the tachometer.Choose a location that

Tachometer Signal Hookup

This Performance Tachometer lets you use one of three options (described
below) to pick up a tachometer signal from the vehicle's ignition system.
Choose the option best suited for your vehicle/system and proceed to the
appropriate "Connection Instructions".

NOTE: Due to the various ways the tachometer signal on this type of system is
processed; this tachometer is compatible with some but not all "Coil On Plug"
systems.

1. OPTION #1 - Direct Hookup with GREEN Wire - the GREEN tachometer

wire is connected directly to the vehicle's "Ignition System Tachometer
Signal Port".

■ Use this option on any vehicle/ignition system where a suitable

tachometer port is available (including Conventional, Distributorless,

and Coil-on-Plug ignition systems).

2. OPTION #2- Inductive Pick-Up on Ignition Coil Wire - the Inductive Pick-

Up is clamped around the "Ignition Coil Wire" to pickup a tachometer sig­nal inductively.

■ Use this option on any vehicle with a Conventional(distributor-equipped)

ignition system with an exposed coil wire where a suitable tachometer
signal port is not available or not easily accessible.

3. OPTION #3- Inductive Pick-Up on Spark Plug Wire - the Inductive Pick-

Up is clamped around one of the "Spark Plug Wires" to pickup a tachome­ter signal inductively.

■ Use this option on vehicles with Conventional (distributor equipped) or

Distributorless Ignition Systems-DIS where the Direct Hookup Option
cannot be used because a suitable tachometer signal port is not avail­able or not easily accessible.

Connection Instructions for OPTION #1 - Direct Hookup
with GREEN Wire

1. Connect the GREEN wire to the negative side of the ignition coil, or to a

suitable tachometer signal port as follows (see Figure 3):
A. Plug the tachometer signal GREEN wire 4-pin female connector into the

B. Use an existing firewall grommet, or drill a 3/8-inch (9,5 mm) hole through

firewall.Install a grommet in hole and route the GREEN lead wire from the
tachometer through grommet and into the engine compartment.

C. For conventional 4-cycle and Coil on Plug ignition systems, connect the

GREEN wire to the negative side of the ignition coil (on Coil-On-Plug
Systems, make the connection to the negative side of oneof the coils only).

D. For Distributerless ignition systems make the connection to a suitable

tachometer signal port.

2. Proceed to the "CYLINDER SETTING INSTRUCTIONS" section to adjust

the tachometer to the proper Cylinder/RPM setting for the "Direct Hookup
with GREEN Wire” option.

Connection Instructions for OPTION #2 - Inductive Pick-Up
on Ignition Coil Wire

1. Connect the Inductive Pick-Up to the Ignition Coil Wire as follows (see

Figure 3):

Shift Light Operation and Setting

The shift light can be used to provide a visu­al indication of engine "Red Line" (maximum
safe engine speed) or optimum gear shifting
engine speed (to improve vehicle perform­ance when shifting gears). See Figure 5.

Setting Shift RPM

1. With the ignition key in the "ON" posi-

tion and the engine "OFF" (not run­ning), press and hold down the shift
light set button.After about 4~5 seconds, the needle will start moving up the
display. Continue holding the shift button down and proceed to step 2.

2. When the tachometer’s needle indicates the desired "shift RPM speed" on
the display, release the shift light set button. The "shift RPM " is now set in
the tachometer's memory, and the shift light will illuminate every time the
needle reaches or exceeds the set "shift RPM ".

3. After the "shift RPM " is set, press and release the shift light set button to
return to the normal tachometer operating mode.

4. To check the shift light RPM setting, press and release the shift light set but­ton. Press and release again to retur n to normal tachometer operation. If
the "shift RPM setting" needs to be changed, repeat steps 1~3.

SHIFT LIGHT/RPM RECALL OPERATION (For Shift Light/RPM Recall Tachometers Only)

5

Peak RPM Recall Function

This function saves the highest (peak) RPM that was achieved during a trip in
the tachometer's memory and gives the operator the ability to recall this infor­mation at any time.

To view the peak RPM value stored in recall memory, press and release the
RPM recall button. Press and release again to return to normal operation.

NOTE: The Peak (highest) RPM achieved during a trip will remain in the
tachometer’s memory until overwritten by a higher RPM valu, or until the mem­ory is cleared by the operator.

Clearing Peak RPM from Tachometer's Memory

1. Press and release the RPM recall button to place the tachometer in RPM

recall mode. The needle should r ise and remain at whatever value is in
Recall Memory.

2. While tachometer is in RPM Recall mode, press and hold the RPM Recall
button. Within 3 ~ 4 seconds, the tachometer’s needle will begin to move
down.Wait until the needle reaches zero, then release the RPM Recall b ut­ton.The RPM Recall memory is now cleared, and the tachometer will begin
saving the highest (peak) RPM reached during the next trip.

Figure 5

If the tachometer does not function, or functions erratically , perf orm the follo wing:

■ Ensure that the ignition system is in good working order in accordance with

the vehicle manufacturer’s specifications. If the ignition system is in good
working order but you still experience erratic readings, the tachometer may
be picking up Electromagnetic Interference (EMI).Try re-routing the Inductive
Pick-Up lead wire or the GREEN tachometer signal wire (whichever is appli­cable) away from all other spark plug wires, ignition coils and the alternator.

TROUBLESHOOTING

6

■ If the Inductive Pick-Up option is being used, reverse the direction of the

Inductive Pick-Up clamp on the spark plug wire so the arrow points away
from the spark plug. If this is unsuccessful, tr y moving the Inductive Pick­Up clamp to a different location on the spark plug wire, or to a different
spark plug wire.

CYLINDER SETTING INSTRUCTIONS

4

The tachometer's CYL setting must be adjusted to match the tachometer's
internal settings to the RPM signal received from the vehicle's ignition system.
Adjust the settings as follows:

1. Make sure the tachometer power and
ground wires are connected to the vehi­cle, and the 3-pin connector is plugged
into the #2 connector on back of the
tachometer.

2. Remove power from the tachometer
(turn ignition switch off). Press and hold
the CYL button (small RED button on
rear of tachometer, see Figure 4), then
apply power to the tachometer (turn igni­tion switch on).

3. Press and release the CYL button as many times as required until the
tachometer's needle points to the correct RPM for the signal hookup option
used.

■ Use the settings in Table 1 if "OPTION #1- Direct Hook Up with GREEN

Wire" or "OPTION #2 -Inductive Pick-Up on Coil Wire” is being used.

■ Use the settings in Table 2 if "OPTION #3 - Inductive Pickup on Spark

Plug Wire" is being used.

4. When the correct cylinder setting is obtained, turn the ignition off.The cylin-

der setting is now saved in the tachometer's memory, and will remain until
changed.To change the setting, repeat steps A through D.

5. Proceed to "Tachometer Operational Checkout" to finish installation.

Tachometer Operational Checkout

1. Turn on ignition. DO NOT START ENGINE.Tachometer pointer should rotate

to "0" when ignition is turned on.
NOTE: This tachometer utilizes an "Air Core Movement".With this type of

movement, the needle will remain (point) at whatever position it was in (not
necessarily zero) at the time the power to the tachometer was removed.
This behavior is normal for this type of needle movement. The needle
should return to zero when power is reapplied to the tachometer.

2. Start and run engine. Rev engine se veral times and verify tachometer indica­tion changes as RPM increases and decreases. If tachometer fails to oper­ate, or operates erratically, consult the Troubleshooting section for trou­bleshooting details.
