This section must be read and followed before installation of the gauge is per-
formed.
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 forget 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 follow-
ing notes.
NOTES:
■ If the vehicle's original temperature sending unit is used by the vehicle’s
computer for engine control functions, DO NOT REPLACE. Consult the deal-
er (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 accom-
modate 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 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 condi-
tion, oil system level and condition, charging system condition, etc.). Never
rely on the gauges as the ONLY means of protection.

A. PANEL INSTALLATION
For On-Dash or Under-Dash mounting (panels are
optional with some gauge models and must be pur-
chased 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 direc-
tion until gauge is tight against dashboard/panel.
Tighten locking ring HAND TIGHT ONLY.

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 avail-
able 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 vehi-
cle's service manual for proper wire).
GAUGE LIGHT INSTALLATION AND CONNECTION 3
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.

Installation
A. ELECTRICAL OIL PRESSURE
1. Determine routing for gauge lead wires. Use an existing firewall grommet, or drill
a 3/8" (9,53 mm) hole through firewall to accommodate lead wires. Install a rub-
ber grommet (purchased separately) in hole, and use shrink tubing to protect
lead wires from chaffing or other damage.
2. Remove existing oil pressure sender. Install oil pressure sender provided with
gauge and tighten securely using proper wrench.
NOTE: Two types of oil pressure senders are used on oil pressure gauge kits.
Both senders work basically the same but the letter markings to identify the
"Sender" terminal and the "Warning Light" terminal on the senders are different.
Make connections as applicable.
NOTE: Oil pressure sender must ground to vehicle chassis. Do not use sealing
compound or Teflon tape on sender threads.
3. Crimp or solder ¼" (6,35 mm) female spade connectors (included) on gauge
positive (+), negative (-), and sender (S) wires.
NOTE: Wire must be purchased separately. Use 18-20 AWG stranded copper wire.
4. Crimp or solder bullet/spade connector (provided) on remaining end of sender wire.
5. Connect lead wires to gauge positive (+), negative (-), and sender (S) spade
posts. Route sender wire through grommet in firewall.
6. Connect negative (-) lead wire to a good bare metal electrical chassis ground.
7. Connect positive (+) lead wire into an existing switched (hot only when the igni-
tion switch is in the “ON” position) positive (+) accessory line in vehicle fuse
block. Insulate splices with electrical tape to prevent shorting.
8. Connect sender (S) lead wire to sender “S” or “G” terminal (as applicable) on oil
pressure sender.
9. If desired (or mandatory), existing oil pressure warning light can be used in con-
junction with the Electrical Oil Pressure Gauge. (Only compatible with some
original equipment sending units that have only one lead wire. See note follow-
ing for details.)
■ Disconnect warning light lead wire from vehicle’s existing oil pressure send-
ing unit, and crimp or solder bullet/spade connector on warning light lead
wire. Connect the warning light lead wire to warning light “W.L./G.” or “WK”
terminal (as applicable) on the oil pressure sender.
