Sunpro, a business unit of SPX Corporation DISCLAIMS ANY LIABILITY

disclaimer may or may not apply to you. This warranty gives specific legal
rights, and you may also have rights, which vary from state to state.
SHIFT LIGHT LAMP REPLACEMENT
The External Shift Light also uses a wedge base lamp
for illumination.
To replace the Shift Light lamp, follow steps to open
the shift light (see figure 10). Remove the lamp from
its socket by pulling it straight out. Replace the lamp
with a #168 automotive lamp. If light is too bright,
replace with a lamp of less intensity such as #194 or #161.
Reassemble the shift light by reversing the steps.
BLACK, RED, AND WHITE WIRE CONNECTIONS
– ALL SYSTEMS
1. Connect the BLACK wire to the negative (-) battery
terminal, or a clean unpainted chassis ground using a
ring terminal or other suitable means (see figure 5.)
Make the following connections with wire splices, or
by an alternative method if desired (see figure 6.)
2. Connect the RED wire to any vehicle harness wire
which is energized with battery voltage, ONLY when the
ignition key is in the ON (RUN) position, NOT OFF OR
ACCESSORIES (see figure 5.)
3. Connect the WHITE wire to the instrument panel
lighting circuit that is controlled by the instrument panel
dimmer control (see figure 5.)
Some vehicles (typically imported) wire the dimmer control
into the ground side of the instrument panel lighting
circuit, as opposed to the more conventional “hot” or 12-volt
side. In vehicles which use this circuit, connect the WHITE
wire to a circuit which is energized by the headlamp switch.

GREEN WIRE CONNECTION
The GREEN wire provides the tachometer with the engine
RPM (speed) signal.
DISTRIBUTOR EQUIPPED ENGINES
Connect the GREEN wire to the negative (-) side of the
ignition coil. This terminal may also be referred to as the
TACH, TACH TEST, DEC, or ECU terminal.
DISTRIBUTORLESS IGNITION SYSTEM EQUIPPED
ENGINES
If your vehicle’s DIS ignition system has a tachometer
output lead set the switch to the 4 Cylinder position for the
4 cylinder engines and to the 6 Cylinder position for the
6 cylinder engines. Connect the tachometer GREEN wire
to the vehicle’s tachometer output lead.
If your vehicle’s DIS ignition system does not have a
tachometer output lead but allows access to the driver
wires from the vehicle computer to the ignition module,
set the switch to the 2 Cylinder position regardless of the
number of cylinders in the engine. Connect the tachometer
GREEN wire to either of the driver wires.
MULTIPLE SPARK DISCHARGE IGNITION
SYSTEM EQUIPPED ENGINES
For Multiple Spark Discharge ignition systems, connect
the GREEN wire only to the tachometer output terminal on
the ignition module. Do NOT connect to the ignition coil.
SHIFT LIGHT RPM TRIP POINT SET-UP
Some possible uses for the Shift Light are:
Engine RED LINE (maximum safe operating speed of
the engine)
Engine maximum torque RPM (for maximum
performance shifting) and desired shift speed.
NOTE: You will need both hands free to set the
tachometer (see figures 7 and 8).

1. Turn the ignition key to the ON position. The engine does
not have to be running.
2. Push and keep the LOWER knob depressed.
3. Push in and rotate the UPPER control knob until the
tachometer pointer indicates the RPM trip point at
which the Shift Light should turn ON.
4. Release both the LOWER knob and the UPPER
control knob.
Note: If at any time the tach pointer appears to freeze
beyond the 10,000 RPM marker: 1) Turn on the ignition
2) Push and hold both knobs 3) Turn the UPPER knob
fully clockwise and then return to the desired trip point.

SUBSTITUTION OR REPLACEMENT
The tachometer is supplied with a #168 wedge base
lamp. If the light is too bright, replace with a lamp of less
intensity such as a #194 or #161.
The lamp socket is located in the rear of the housing
of the tachometer (see figure 9). To remove the lamp, gently
grasp the black lamp socket (use pliers if necessary)
and twist it counterclockwise approximately 1/8 turn
until it stops. Pull the socket with lamp straight out of the
tachometer housing. Remove the lamp from its socket
by pulling it straight out. Replace the lamp. Reinstall the
socketed lamp by rotating it against the tachometer’s
internal PC board until it drops into place, and then rotate
it approximately 1/8 turn clockwise until it reaches its
mechanical stop. 0002-000-2861
