This section

must

be read and followed before installation of the gauge is

performed.

1. Read instructions completely before installation.

2. Install gauges only when engine is cool and ignition is off.

3. Make sure all necessary tools, materials, and parts are on hand.

4. Always read the vehicle's service manual and follow it’s safety precautions

before any test or service procedure is performed.

5. Disconnect negative (-) battery cable before installing gauges (do not for-
get to reconnect battery after installation is complete).

6. Locate the vehicle's oil pressure and/or coolant temperature sending units,

and verify the vehicle's sending unit port thread size is compatible with the
thread size on the gauge's sending unit and/or the supplied adapters. DO
NOT DRILL ANY HOLES IN DASH BEFORE ENSURING COMPATIBILITY.
See the following notes.

NOTES:

■ If the vehicle's original temperature sending unit is used by the computer
for engine control functions, DO NO T REPLA CE.Consult the dealer (or a
professional) to determine if the new sending unit can be installed in an
alternate location on the engine.If no suitable location is found, this gauge
is not suitable for your application.(See below for oil pressure gauge.)

■ For oil pressure gauges, a T-fitting (sold separately) may be used to
accommodate the new gauge sending unit, and to keep the vehicle's
original sender operational.

7. Determine a mounting location for the gauge. Choose a location that does
not impair visibility or interfere with driving. Check behind the mounting
location for any wiring or components before drilling.Also take into consid­eration the routing and length of the lead wires, nylon tubing and/or the cap­illary tube from gauge to engine sender port.

WARNING: Follow vehicle manufacturer’s service recommendations.
Check and maintain the vehicle’s engine regularly (cooling system level
and condition, oil system level and condition,charging system condition,
etc.). Never rely on the gauges as the ONLY means of protection.

NOTE: For information on optional mounting configurations and mounting
hardware, visit us on the web at www.iequus.com

A. PANEL INSTALLATION

For On-Dash or Under-Dash mounting (panels
are optional with some gauge models and
must be purchased separately).

1. Determine mounting location (see section 1,

step 7).

2. Using gauge panel as a template, mark loca­tions for screws.

3. Drill small holes for the screws.

4. Mount panel in place and secure with screws

and flat washers provided.

MOUNTING AND INSTALLATION

2

B. IN-DASH MOUNTING

1. Using a hole template, cut out a 1-1/2", 2" or 2-5/8" (3.81 cm, 5.08 cm, or 6.67

cm) hole, as necessary, through the dashboard.

2. Using a round file, smooth out the rough edges around the drilled hole.

C. INSTALLING GAUGE INTO GAUGE

PANEL OR IN-DASH

1. Insert gauge through front of panel or hole in

dashboard, as applicable.

2. Hold gauge case and rotate gauge, as need­ed, until gauge dial face is properly posi­tioned in front of dashboard/panel. Secure
gauge in place.

3. Tighten locking ring on gauge in clockwise
direction until gauge is tight against dash­board/panel. Tighten locking ring HAND
TIGHT ONLY.

Figure 2. Gauge Equipped

with Locking Ring

NOTE: Depending on the model of gauge, backlighting color may be changed

to either red, green or blue by installing the optional color filter over the bulb
(not available for all gauge kits).

1. Insert the light bulb and socket assemblies
into the light receptacles on the back of the
gauge and press firmly to snap/lock into
place.

NOTE: Wire for gauge lights must be pur­chased separately. Use size 18-20 AWG
stranded copper wire.

GAUGE LIGHT INSTALLATION AND CONNECTION

2. Splice the RED or WHITE wire from the gauge light(s) into the vehicle's

lighting circuit, between the dimmer control switch and the dash lights (con­sult the vehicle's service manual for proper wire).

3. Connect light socket BLACK wire to a good chassis ground.

4. Insulate all connections with shrink tubing to prevent shorting.

WARNING: For bulb replacement use only part # 161 Instrument/
Indicator wedge type bulbs available at most auto parts stores. DO
NOT USE ANY OTHER PART NUMBER SINCE THE HEAT PRODUCED
BY A HIGHER WATTAGE BULB WILL MELT THE GAUGE CASE AND
CREATE A FIRE HAZARD.

A. VOLTMETER

1. Using a multimeter or test light, find a 12-volt positive (+) location that is hot

ONLY when the ignition key is in the "ON" position (possible locations: fuse
panel accessory, radio and cigarette lighter circuits).

NOTE:Wire must be purchased separately.Use 18-20 AWG stranded cop­per wire.

2. Crimp or solder ¼" (6.35 mm) female spade/ring terminals (included) on
one end of voltmeter positive (+) and negative (-) wires, and connect wires
to voltmeter positive (+) and negative (-) terminal ring/spade posts, as appli­cable.

3. Connect voltmeter positive (+) wire to an accessory location or line as
described in step 1.

4. Connect voltmeter negative (-) wire to a good bare metal chassis ground on
the vehicle.

NOTE:To prevent electrical shorts, route wires away from sharp edges and
parts. Insulate all splices with shrink tubing.

5. Reconnect the negative (-) battery
cable. With the ignition switch in
the "ON" position and engine NOT
RUNNING, voltmeter should read
between 12.5 and 13.2 volts. A
lower reading indicates a low bat­tery, a poor connection or
dirty/defective battery cables.

6. Start and run engine. Voltmeter
should read between 13.3 and

15.2 volts (specifications vary,
consult your vehicle's service
manual for proper specifications).A lower reading can indicate a faulty volt­age regulator, slipping belts, faulty alternator/battery, a poor connection or
excessive loads.A higher reading can indicate a faulty voltage regulator.

NOTE: If voltmeter fails to read, make sure positive (+) and negative (-)
connections on rear of gauge match. If voltmeter still fails to read, recheck
and tighten all connections.

B. MECHANICAL OIL PRESSURE

NOTE: Before installation, use shop cloths and drip pans to protect interior

from potential vehicle leaks.

1. Determine routing for nylon tubing.Use an existing firewall grommet, or drill
a 3/8” (9.53 mm) diameter hole through firewall to accommodate nylon tub­ing. Install a rubber grommet (purchased separately) in hole, use shrink
tubing to protect nylon tubing from chaffing or other damage.

NOTE: Some gauges require a tubing kit (purchased separately) for instal­lation.

2. Connect nylon tubing to gauge using compression sleeve and compression
nut.Tighten compression nut until tubing is secure.

3. Route nylon tubing through grommet in firewall.

4. Locate correct oil pressure port on engine and, if required, install proper

adapter from gauge kit.
NOTE: Adapters for most Domestic/Asian vehicles included (excludes 6500

Series gauges). Additional adapters purchased separately.

5. Connect nylon tubing to pressure port adapter using tube connector, com­pression sleeve and compression nut.Tighten compression nut until tubing
is secure.

6. Secure tubing along its route to prevent damage from sharp edges, moving
parts or hot engine components.

7. Reconnect negative (-) battery cable. Start and run engine for approxi­mately 30 seconds.Turn off engine and check gauge installation for leaks.
Tighten or reseal joints as needed and retest.

C. MECHANICAL TEMPERATURE

1. Determine routing for temperature sensor. Use an existing firewall grom-

met, or drill a 7/8” (22.23 mm) hole through firewall to accommodate capil­lary tube with sensor. Install a rubber grommet (purchased separately), in
hole to protect capillary tube from chaffing or other damage.

CAUTION:The capillary tube is a sealed, pressurized tube that is filled with
Ether gas. NEVER CUT THE TUBE OR ATTEMPT TO REMOVE IT FROM

THE GAUGE PORT.

2. Route capillary tube through grommet in firewall.

3. Remove the vehicle's existing temperature sending unit. Install the proper

size adapter (an adapter must be used to properly seat temperature
sender; see section 1, item 6) in sender hole and tighten securely. Insert
temperature sensor in adapter and tighten sensor nut securely. DO NOT
ROTATE SENSOR OR CAPILLARY TUBE WHILE TIGHTENING NUT OR
CAPILLARY TUBE MAY BE DAMAGED.

NOTE: Adapters for most Domestic/Asian vehicles included (excludes 6500
Series gauges). Additional adapters purchased separately.

4. Secure capillary tube along its route to prevent damage from sharp edges,
moving parts or hot engine components. DO NOT CRIMP, KINK OR MAKE
SHARP BENDS IN THE CAPILLARY TUBE.

5. Reconnect negative (-) battery cable. Start and run engine and check
gauge installation for leaks.Tighten or reseal joints as needed and retest.
