Equus 8080 - 5 Shift Light Tachometer (DIS) - Manual

INSTALLATION INSTRUCTIONS
PERFORMANCE TACHOMETER
PREPARATION BEFORE INSTALLATION 1
This section contains important preliminary information. Read this section
FIRST before proceeding with installation.
Safety Precautions
To prevent personal injury, damage to the vehicle and/or the tachometer, read
these instructions completely and observe the following safety precautions:
■ Always consult the vehicle's service manual and follow its safety precau-
tions before installing this gauge.
■ To prevent burns, install the tachometer only when the engine is cool.
■ The vehicle's exhaust is very toxic, to prevent serious injury or death always
run the vehicle in a well ventilated area.
■ When an engine is running, cooling fans, pulleys, belts, etc. rotate at a very
high rate of speed. ALWAYS be aware of moving/rotating parts, and keep a
safe distance away from these items.
■ Disconnect the negative (-) battery cable before installing and/or making
tachometer connections.
NOTE: It may be necessary to reprogram your radio, clock, etc. after recon-
necting the battery.
■ ALWAYS insulate wire splices with shrink tubing to prevent shorting.
Applications
This tachometer is compatible with 12 volt negative (-) ground systems ONLY,
and will work on most of the following ignition systems:
■ DISTRIBUTOR EQUIPPED - 4 cycle ignition systems
■ DISTRIBUTORLESS (DIS) and other 2 cycle Ignition Systems - these
type of systems are no longer equipped with distributors.
NOTE: This tachometer may not work on some vehicles with the following igni-
tion systems:
■ Multiple Spark Ignition Systems: Consult manufacturer and/or instruc-
tions on how to connect a tachometer to these systems.
■ Direct (coil on plug) Ignition Systems: Consult the vehicle’s service
manual to determine if an adequate tachometer signal connector is avail-
able for connecting an aftermarket tachometer.
■ Determine a mounting location for the tachometer. Choose a location that
does not impair visibility, or interfere with driving. Check behind the
mounting location for any wiring or components before drilling. Ensure that
all the tachometer wires can be routed properly to their specific locations
from the mounting location chosen.
On-Dash or Under-Dash
Mounting
1. Install the base mount and secure
with screws, washers and nuts pro-
vided.
2. Install the ring clamp type mount to
the tachometer body.
3. Using the spacer and bolts provided,
secure the tachometer and ring clamp
type mount assembly to the base
bracket. SEE FIGURE 1.
4. Proceed to section 3 for tachometer
connection.

TACHOMETER CONNECTIONS 3
Power and Ground Connections (Figure 3)
1. Plug the 3-pin power connector (RED, BLACK and WHITE wires) into the
#2 connector on back of the tachometer.
2. Connect the tachometer's power (RED) wire to a switched +12 volt circuit
at fuse box, or splice into a vehicle harness wire that has voltage ONLY
when the ignition key is turned to the "ON" (RUN) position.
3. Crimp or solder a terminal lug on the ground (BLACK) wire, and connect to
a clean, bare spot on the vehicle's metal frame.
4. Connect the tachometer's lighting (WHITE) wire to the instrument panel
light circuit (consult vehicle's repair manual for wiring diagrams). Proceed
to tachometer signal hookup.
NOTE: To install the light bulbs, use needle nose pliers to insert the bulb in the
bulb receptacle on back of gauge, then twist clockwise ¼ turn to lock into place.
Gauge backlighting color may be changed to RED, GREEN or BLUE by
installing the desired color filter over the bulb (not available for all gauge kits).
Tachometer Signal Hookup
This Performance Tachometer lets you use one of three options (described
below) to pick up a tachometer signal from the vehicle's ignition system.
Choose the option best suited for your vehicle/system and proceed to the
appropriate "Connection Instructions".
NOTE: Due to the various ways the tachometer signal on this type of system is
processed; this tachometer is compatible with some but not all "Coil On Plug"
systems.
1. OPTION #1 - Direct Hookup with GREEN Wire - the GREEN tachometer
wire is connected directly to the vehicle's "Ignition System Tachometer
Signal Port".
■ Use this option on any vehicle/ignition system where a suitable
tachometer port is available (including Conventional, Distributorless,
and Coil-on-Plug ignition systems).
2. OPTION #2- Inductive Pick-Up on Ignition Coil Wire - the Inductive Pick-
Up is clamped around the "Ignition Coil Wire" to pickup a tachometer sig-
nal inductively.
■ Use this option on any vehicle with a Conventional (distributor-equipped)
ignition system with an exposed coil wire where a suitable tachometer
signal port is not available or not easily accessible.
3. OPTION #3- Inductive Pick-Up on Spark Plug Wire - the Inductive Pick-
Up is clamped around one of the "Spark Plug Wires" to pickup a tachome-
ter signal inductively.
■ Use this option on vehicles with Conventional (distributor equipped) or
Distributorless Ignition Systems-DIS where the Direct Hookup Option
cannot be used because a suitable tachometer signal port is not avail-
able or not easily accessible.
Connection Instructions for OPTION #1 - Direct Hookup
with GREEN Wire
1. Connect the GREEN wire to the negative side of the ignition coil, or to a
suitable tachometer signal port as follows (see Figure 3):
A. Plug the tachometer signal GREEN wire 4-pin female connector into the
4-pin connector #1 on back of tachometer.
B. Use an existing firewall grommet, or drill a 3/8-inch (9,5 mm) hole through
firewall. Install a grommet in hole and route the GREEN lead wire from the
tachometer through grommet and into the engine compartment.
C. For conventional 4-cycle and Coil on Plug ignition systems, connect the
GREEN wire to the negative side of the ignition coil (on Coil-On-Plug
Systems, make the connection to the negative side of one of the coils only).
D. For Distributerless ignition systems make the connection to a suitable
tachometer signal port.
2. Proceed to the "CYLINDER SETTING INSTRUCTIONS" section to adjust
the tachometer to the proper Cylinder/RPM setting for the "Direct Hookup
with GREEN Wire” option.
Connection Instructions for OPTION #2 - Inductive Pick-Up
on Ignition Coil Wire
1. Connect the Inductive Pick-Up to the Ignition Coil Wire as follows (see
Figure 3):
A. Use an existing firewall grommet, or drill a 3/8-inch (9,5 mm) hole
through firewall. Install a grommet in hole and route the Inductive Pick-
Up 4-pin female connector from the engine compartment side through
grommet and to the tachometer.
NOTE: The Inductive Pick-Up lead wire is a special shielded wire. DO
NOT cut the wire.
B. Plug the 4-pin Inductive Pick-Up connector into the 4-pin connector #1
on back of tachometer.
C. Remove the screw and nut from the Inductive Pick-Up Clamp.
D. Find the Ignition coil wire, and clamp the Inductive Pick-Up around the
wire. Make sure that the arrow stamped on the Inductive Pick-Up clamp
points toward the distributor.
E. Re-install the screw and nut to secure the inductive pick up clamp on to
the ignition coil wire.
2. Proceed to the "CYLINDER SETTING INSTRUCTIONS" section to adjust
the tachometer to the proper Cylinder/RPM setting for the "Inductive Pick-
Up on Ignition Coil Wire” option.

In-Dash Mounting
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.
4. Insert gauge through in dashboard.
5. Hold gauge case and rotate gauge, as
needed, until gauge dial face is properly
positioned in front of dashboard.
6. Tighten locking ring on gauge in clockwise
direction until gauge is tight against dash-
board. Tighten locking ring HAND TIGHT
ONLY. SEE FIGURE 2.
