© 2004 IEC - All Rights Reserved MRP #93-0033

1. Read instructions completely before installation.Seek the advice of

a professional if you are not familiar with the installation of vehicle
instrumentation or the functions of related vehicle systems.

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 pre-

cautions.

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

NOTE:It may be necessary to reprogram your radio, cloc k, etc.after

reconnecting the battery.

NOTE: Additional mounting options (pillar mount, console mount, etc.)
and hardware are available for some gauges. For information on
optional mounting configurations, mounting hardware and prices, visit
us on the web at www.iequus.com

A. PANEL INSTALLATION
For On-Dash or Under-Dash mounting

(panel is optional with some gauge models
and must be purchased separately).

1. Determine the mounting location for the

gauge.

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

3. Drill small holes for the screws and secure
panel with screws and flat washers provided.

MOUNTING AND INSTALLATION

2

B. IN-DASH MOUNTING OPTION

1. Determine a location on the dashboard that can be cut out without

striking any objects behind the dash.

2. Using a hole template, cut out a 1-1/2" (3,8 cm), 2" (5,1 cm) or
2-5/8"(6,7 cm) hole, as necessary, through the dashboard.

3. 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.

2. Hold gauge case and rotate gauge, as

needed, until gauge dial face is prop­erly positioned in front of dashboard/
panel.

3. Tighten locking ring on gauge in clock-

wise direction until gauge is tight
against dashboard/panel. Tighten
locking ring HAND TIGHT ONLY.

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.

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).

GAUGE LIGHT INSTALLATION AND CONNECTION

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

4.

Insulate all splices and connections with
shrink tubing to prevent shorting.

WARNING: For bulb replacement
use onl

y 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.

Install Vacuum/Boost gauge as descr ibed in Section 2, MOUNTING
AND INSTALLATION.

Determine routing for pressure line. Use an existing firewall grommet
or drill a 3/8" (9,5 mm) diameter hole through firewall to accommodate
pressure line.Install a rubber grommet (purchased separately) in hole,
to protect lead wires from chaffing or other damage. Use Teflon tape
(purchased separately) on all adapter threads to prevent leaks.

NOTE: The pressure fitting instructions that follow are for the installa­tion of gauges that have a BOOST function. If the gauge you are
installing does not have a BOOST function, simply connect the vacu­um tubing to the back of the gauge fitting, and then to an existing
intake manifold vacuum hose using the "T" fitting. No pressure tubing
is needed for vacuum gauges that do not ha v e a BOOST function, and
the section of the instructions describing pressure fitting connections
can be disregarded.

MAKING CONNECTION TO GAUGE

1. Connect nylon pressure tubing to gauge using compression sleeve

and compression nut provided.Tighten compression nut until tub­ing is secure. See Figures 4 and 5.

2. Route nylon tubing through grommet in firewall.
MAKING CONNECTION TO VEHICLE

■■

Some vehicles are factory equipped with a tapped hole on the
intake manifold that is suitable for the Boost/Vacuum gauge nylon
tubing connection. If your vehicle is equipped with a suitable tap
on the intake manifold f ollo w the directions for "Option One - Intake
Manifold Connection" (Figure 4).

NOTE: Make sure this is a vacuum port, and not a coolant por t.

■■

On vehicles without a tap on intake manifold, locate an existing vac­uum line where a "T" fitting can be utilized and follow the directions
for "Option Two - Existing Vacuum Line Connection" (Figure 5).

■■

IF YOUR VEHICLE DOES NOT HAVE A TAPPED HOLE ON THE
INTAKE MANIFOLD, AND A SUITABLE VACUUM LINE IS NOT
AVAILABLE, CONSULT A PROFESSIONAL FOR INSTALLATION
OF THIS TYPE OF GAUGE.

Option One - Intake Manifold Connection

See Figure 4 and follow the instructions below:

1. Remove plug from tapped hole on intake manifold and install 1/8" ­27 NPT or 1/4" - 18 NPT adapter, as required, in tapped hole.

NOTE: Additional adapters must be purchased separately.

2. Connect nylon tubing to the installed adapter using compression

sleeve and compression nut provided. Tighten compression nut
until tubing is secure.

Option Two - Existing Vacuum Line Connection

See Figure 5 and follow the instructions below:

1. Connect nylon tubing to the 5/16" (7,9 mm) vacuum nipple using
compression sleeve and compression nut provided. Tighten com­pression nut until tubing is secure.

2. Insert vacuum nipple into one end of the 5/16" X 4" (7,9 mm X 10,2
cm) hose (provided);insert the vacuum "T" fitting into the other end
of the hose.

3. Cut the selected vacuum hose on the vehicle and install "T" fitting
in line with this hose. Use hose clamps (purchased separately) as
needed to secure "T" fitting.

FINISHING THE INSTALLATION

1. Secure tubing along its route to prevent damage from sharp edges,

moving parts or hot engine components.

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