Carefully consider the installation location and driver's operation of the product before installation. Do
not install the product where it interrupts driving and the safety deices of vehicle such as the airbag
system. Be sure not to install the unit where it could fall. Improper installation or operation could
cause the product to fall and damage the vehicle or cause serious danger by impeding driving.
Do not disassemble or modify this product. Such actions will not only void the warranty but also
damage or destroy the product.
Do not perform installation of this product immediately after the engine has been switched off. The
engine and exhaust system are extremely hot at this time and can cause burns if touched.
Ensure that the wiring of this product does not have an adverse impact on the other wiring of the vehicle. Any
controlling devices or other electronic components of the vehicle could be damaged.
Discontinue use of this product if the product doesn't operate or operates improperly. Continued use while the
condition exists could result in an accident or fire.
Please keep children and infants away from the installation area. Children may swallow small parts or be injured in
other ways.
Do not install this product in the area where safety equipment such as airbags are mounted. This may cause more
injuries in the event of an accident.
Danger
Ensure that the vehicle will remain stationary and turn off the engine before installing this product. Failure to do so
could result in a fire, and could make the vehicle move during installation.
Remove the key from the ignition and disconnect the negative (-) battery terminal prior to installation of this product.
Failure to do so could result in a fire caused by an electrical short circuit.
Take care not to install this product in a way that interferes with safety equipment such as seat belts and air bag
systems or vehicle operation equipment such as engine controls, steering wheel or brake systems. Interference
with normal operation of the vehicle can result in an accident or fire.
Solder or use a solderless connector for wiring connections and make sure connections are insulated. In areas
where there could be tension or sudden impacts on the wiring, safeguard the wiring with corrugated tubing or other
shock absorbent material. Accidental shorts can cause fires.
When wiring power supply wire, to avoid the risk of electrical shock or fire, be sure to confirm that there is no
disconnection or breakage of wire. Poor connection can result in short-circuit, electrical shock, fire, or other hazards.
The ignition-switched +12V(IGN) line must be connected to the vehicle's ignition-switched wire with a fuse of 30A or
less. High-capacity fuse(more than 30A) will not blowout even with an abnormal current flow and may cause fire.
Use the fuse of regulated capacity when the fuse of the power wire is changed. Using a fuse that exceeds regulated
capacity may cause fire and may affect the accuracy.
Do not install the product at the wet places. It may result in a fire caused by an electrical short circuit.
This product is designed for use on 12V vehicles. Do not install this product on vehicles with 24V systems.
Insulate any unused wires. If any wires or connectors loosen during installation, please make sure
they are correctly reattached.
Do not drop any of the components of this product. It may result in damage to the product.
Do not apply excessive force on switches/terminals. It may result in damage to the product.
Do not use wires other than the provided wires.
Do not attach wires on the body of the vehicle or engine parts as this may result in damage to the product.
Install wires away from ignition and also radio signal frequency interference as this could cause the gauges to
malfunction.
Do not place wires near the engine, exhaust pipe or turbine. It may result in damage or fusion of wires.
Make sure the waterproof processing is done when diverging wires in the engine compartment.
Wear gloves to avoid burns when soldering and cuts when installing wires, sharp edges of parts.
When using sunshade, put sunshade between products and windshield to avoid direct sun exposure .

※If the switch unit is fixed to another place other than the gauge, do not use the
attachment for switch unit.
5) Fit the attachment for switch unit and indicator into the mounting band. And then fit
the gauge into the mounting band. Locate the switch unit and the indicator roughly
at this stage. The switch unit and the indicator can be positioned in the range which
they do not touch the mounting bracket and bolts.【Figure4】【 Figure5】
※Do not take hands off from the gauge so as the gauge does not fall down.
※If the switch unit is fixed to another place other than the gauge, do not fix/use the
attachment for switch unit to the mounting band.
6) Identify the position of the mounting bracket with the gauge fitted into the mounting
band. Mark the shape of the mounting bracket and the position of the screw holes.
The figure printed on the package can be used to position the screw holes.
※To check that there is enough space for installation, identify the gauge position
with the gauge, switch unit, and indicator fitted into the mounting band.
※When setting the gauge angle, take care not to scratch by hitting the gauge to the
mounting bracket.
7) Disassemble the mounting band from the mounting bracket, and disassemble the
gauge, attachment for switch unit, and indicator from the mounting band.
8)
Attach double sided tapes on the bottom of the mounting bracket.【Figure1】【 Figure6】
9) Fix the mounting bracket on the gauge installing position by using the tapping screws.
10) Fit the attachment for switch unit, indicator, and gauge into the mounting band again.
Take notice that the angle of the switch unit and the indicator cannot be changed
while the bolts are fastened.
※If the switch unit is fixed to another place other than the gauge, do not fix/use the
attachment for switch unit to the mounting band.
11) Attach the double sided tape on the back side of the gauge.
【Figure1】【 Figure6】
12) Pass the indicator wire and switch unit wire through the holes of the back case from
the outside. Connect the indicator wire to the connector on the gauge. Refer to part
names section.【Figure7】【 Assembling example】
13)
Put the back case on the gauge. Position the hole for the power supply & tachometer
signal wire to the gauge connector for it. Refer to part names section. The indicator
wire can be stored in the back space in the back case.【Assembling example】
14) Connect the switch unit wire to the connector on the back side of the gauge. The
indicator wire can be stored in the storage space in the back case neatly.
【Assembling example】
15) Connect the power supply & tachometer signal wire to the connector on the back
side of the gauge.【Assembling example】
16) Fit the mounting band with the gauge in the mounting bracket by using a spacer,
bolts, washer, and spring lock washer.
※Depending on the installing space, it may difficult to fit the gauge. Do not pull
wires forcefully and take notice not to hit the vehicle by parts.
17) Fasten the bolts with a hexagonal wrench (Allen key) firmly.【Figure8】
18) Fit the regular position bezel onto the gauge with setting the ▼ mark at the position
you like.

Main Features（for customer）
Lineup（for customer）
●Stepping motor "STS26A"
Maximum angle of deflective 270° (full sweep) is controlled by the microcomputer up to 4600 division（0.057° each) to
provide high precision in the accuracy of information generated.
The stepping motor is sufficient for quick response of all sorts of professional motorsports.
●LED illumination
The gauge dial is invisible while the ignition switch is off. Once the ignition switch is turned on, a clear display appears
by colored LED illumination.
The gauge dial illumination and the red emitting needle pointer provide high visibility.
●Opening and closing modes
The gauge dial and the needle pointer performs opening and closing modes interlocked with turning ON/OFF of the ignition.
●Adjustable brightness
There are 5 stages of brightness for the daytime and 6 stages for the nighttime. The brightness can be
decreased/increased with the vehicle lights switched on/off.
●Dual warnings of light and buzzer
Two customer-defined warning RPMs can be set. When the RPMs are exceeded, the warning LED blinks/lights up
and the warning buzzer sounds.
●Exclusive large-sized indicator
The exclusive large-sized indicator which lights in green and red enhances the visibility of warnings in addition to the
warning LED in the gauge.
●Peak memory function
The maximum RPM during driving can be stored and checked later.
●Detachable switch unit
The large-sized switch unit with light is fixable on the gauge and is also detachable.
●Exclusive mounting band and back case
The gauge is clinched by using the exclusive mounting band and back case. Wires can be stored in the back case neatly.
