SPECIFIC SAFETY PRECAUTIONS
1. Ensure the ignition is off and the engine is cool before installing gauge.
2. Disconnect negative (-) battery cable before installing gauges.
NOTE: You may have to reprogram your radio, clock, etc. after reconnecting the battery cable.
3. Do not alter any parts of the gauge. If the gauge is not functioning properly, contact Princess
Auto for a solution.
4. Make sure the mounting location does not impair visibility or interfere with driving.
5. Check behind the mounting location for any wiring or components before drilling.
6. When connecting electrical wires, install crimp terminals and make wire splices as needed.
CAUTION! Always insulate wire splices with electrical tape to prevent shorting.
INSTALLATION
1. On the rear side of the tachometer (#1), locate the cylinder select switch
and slide it to 4-, 6- or 8-cylinder to match your vehicle (Fig. 1).
NOTE: This tachometer is designed for use with 4-, 6- or
8-cylinder engines only.
2. Determine mounting location and install the mounting
bracket (#2).
a. For on-dash or under-dash mounting, drill a 3/16 in.
hole in the dash. Install base (#4) and mounting bracket
and secure to dash with screw (#7), washer (#8) and nut
(#9). (Fig. 2)
b. To mount on steering column, use large hose clamp
(sold separately) and rubber gasket (#5). (Fig. 3)
3. Route tachometer lead wires through mounting bracket and
tachometer nut (#3).
4. Make necessary connections to tachometer.
NOTE: This tachometer works on vehicles equipped with
either distributor ignition systems or distributorless
ignition systems.
a. Determine routing for tachometer lead wires.
Use an existing firewall grommet, or drill a
3/8 in. hole through firewall to accommodate
lead wires. Install a rubber grommet
(sold separately) in hole, or wrap with
electrical tape, to protect lead wires from
chafing or other damage.

b. Install and crimp or solder
ring terminal (#11) on
tachometer ground (BLACK)
wire. (Fig. 4)
c. Connect tachometer ground
(BLACK) wire to negative (-)
battery terminal or to a good
chassis ground.
d. Connect tachometer power
(RED) wire to a switched
+12V circuit at fuse box,
or splice into any vehicle
harness wire which is
energized ONLY when
ignition key is in ON (RUN)
position.
NOTE: If necessary, use a splice connector (#6) when
connecting tachometer wires to the vehicle’s wire harness.
Insert the tachometer and vehicle wires (Fig. 5), press down
on the piercing clip to pierce wires, then close and latch
splice connector cover.
e. Connect tachometer lighting (WHITE) wire to panel
lights circuit at fuse box, or splice into any vehicle
harness wire connected to the panel lights circuit.
f. Connect tachometer signal (GREEN) wire to
appropriate vehicle tachometer signal source.
NOTE: Tachometer signal (GREEN) wire connections vary with vehicle make, model, and ignition
type. Typical tachometer signal source locations are shown in the accompanying illustrations. (Fig. 6)
Always consult the service manual for the vehicle you are working on to ensure proper connection.
g. Secure lead wires along their route to prevent damage from sharp edges, moving parts or
hot engine components.
h. Start engine and let it run. Rev engine several times and verify tachometer indication
changes as RPMs increase and decrease. Make sure tachometer pointer operation is smooth
and even.
5. Install tachometer on mounting bracket, and secure with tachometer nut.
6. A red RPM pointer (#13) has been provided with this tachometer. You may use this as an
optional shift indicator or max. speed (redline) indicator.
