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. Disconnect negative (–) battery cable before installing gauges.
NOTE: It may be necessary to reprogram your radio, clock,
etc. after reconnecting the battery.

NOTES:
• Some vehicles use temperature and pressure sensors for
engine control functions. Use a T-fitting if necessary when
installing gauge sensors.
• Whenever a T-fitting is used for temperature, gauge reading
will be lower than actual water temperature.
7. When connecting electrical wires, install and crimp or solder
terminals (purchased separately) and make wire splices as
needed. ALWAYS insulate wire splices with shrink tubing or
electrical tape to prevent shorting.
8. Follow all necessary safety procedures for protection.
WARNING: Check and maintain your engine regularly, and be
aware of any irregularities. Never rely on the gauges as the
ONLY means of protection.
For on-dash or under-dash mounting.
1. Determine mounting location.
2. Using panel as a template, mark
locations for screws.
3. Drill small holes for the screws.
4. Hold panel in place and secure
with the screws and flat
washers provided.
PANEL INSTALLATION
2
1. Locate a position on the dashboard that can be cut out without
striking any objects from behind the dash.
2. Using a hole template, cut a 1-1/2" or 2" hole, as necessary,
through the dashboard.
3. Using a round file, smooth out the rough edges around the
drilled hole.
4. Install the gauge as described in step 4, GAUGE
INSTALLATION.
IN-DASH INSTALLATION
3
1. Insert gauge through front of
PANEL or hole in dashboard.
2. Install U-bracket over gauge
mounting studs and secure with
two nuts and flat washers
provided. TIGHTEN NUTS
FINGER-TIGHT ONLY.
NOTE: Ammeters and the 1-1/2"
voltmeter gauge utilize U-brackets which have two black
insulators installed in the mounting holes. MAKE SURE THESE
INSULATORS ARE PRESENT BEFORE INSTALLING THE
U-BRACKET.
3. Hold gauge case and rotate gauge, as needed, until gauge face
is positioned properly on front of panel.
4. After positioning, tighten mounting nuts securely to prevent
gauge movement. DO NOT OVERTIGHTEN NUTS OR U-
BRACKET MAY WARP.
GAUGE INSTALLATION
4
NOTE: Gauge backlighting color may
be changed to red or green by installing
the optional color filter over the bulb (not
available for all gauge kits).
1. Press snap-in light socket into
collar on back of the gauge.
2. Splice free end of light socket RED wire into an existing
hot wire from any vehicle instrument panel lamp controlled
by the headlight switch. Insulate splice with shrink tubing or
electrical tape to prevent shorting.
3. Connect light socket BLACK wire to a good chassis ground
(additional wire purchased separately).
4. The gauge lights are now connected to the lighting circuit
controlled by the headlight switch. If the vehicle is so equipped,
gauge light brightness will be controlled along with the
instrument panel lights.

A. VOLTMETER
1. Using a multimeter or test light, find a 12 volt positive (+) location
which is hot ONLY when the ignition key is in the "ON" position
(possible locations: fuse panel accessory, radio and cigarette
lighter circuits).
NOTE: Voltmeter wiring must be purchased separately. Use 18
– 20 AWG wire.
2. Crimp or solder 1/4" female spade/ring terminals (purchased
separately) on one end of voltmeter positive (+) and negative (–)
wires, and connect wires to voltmeter positive (+) and negative (–)
terminal posts.
3. Splice positive (+) wire to an accessory location or line as
described in step 1 (route wires away from sharp edges and
mechanical moving parts to prevent electrical shorts).
4. Connect voltmeter negative (–) wire to a good bare metal
electrical chassis ground on the vehicle.
5. Reconnect negative (–) battery cable. With the ignition switch in
the "ON" position (and engine NOT RUNNING), voltmeter should
read on the lower half of green area (if color coded) or between
12.5 and 13.2 volts. A lower reading indicates a low battery, a
poor connection or defective battery cables.
6. Start and run engine. Voltmeter should read on the upper half of
green area (if color coded) or between 13.3 and 15.2 volts
(specifications vary, consult your vehicle's service manual). 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.
