battery supply, the engine ignition system and the various sensors fitted
to the vehicle to provide the full range of measurements.
If your ST700 Dash Display System includes the option to trigger lap
times automatically, you will also require a vehicle–mounted infrared
(IR) sensor and a track–side IR beacon.

Safety Issues
You must take note of the following safety advice when you install the
ST700 Dash Display System on your vehicle:
Follow the instructions to attach all components of the system se-
curely to the vehicle so that they do not vibrate loose and fall off.
The wiring harness supplied with the ST700 Dash Display System
is certified for use in high temperature applications up to 105°C
(221°F). Do not substitute wires that have a lower temperature rat-
ing than this. Contact Stack for advice if you are in any doubt.
Route all wires and the wiring harness so they do not snag against
any moving parts of the vehicle.
Do not apply sharp bends or other severe stresses to the wiring
harness.
Avoid positioning the sensors or their wires close to any sources
of intense heat or vibration or close to the leads of the ignition HT
or fuel injection systems.
Use cable clips to secure the wiring harness.
Use suitable glands or grommets to protect the wiring harness
where it passes through vehicle bulkheads or panels.

INSTALLATION
You do not need complicated tools or special training to install the ST700
Dash Display System. To gain the benefits of using this quality instru-
ment all you need are a few basic workshop tools, the willingness to
read and follow these instructions carefully and the time to complete
each task in sequence.
Refer to the instructions between page 43 and page 59 for instruc-
tions to set up the ST700 Dash Display System display and alarm lim-
its specifically for your vehicle.
Product Installation
The installation process begins when you start to install the wiring har-
ness, the controls and the ST700 Dash Display System display. After you
have completed these tasks, you can fit and connect the options and
sensors included with your system. You may then connect the ST700
Dash Display System to the vehicle electrical supply.
You will need to cut a hole into the instrument panel to accept the ST700
Dash Display System instrument display. Choose a suitable position for
it:
❑Mount the ST700 Dash Display System display on the instrument
panel so that the driver can see it easily, looking either through or
over the steering wheel, as shown in Figure 1.

display location
❑Position the ST700 Dash Display
System display so that the driver
can see it either square on or
from a position slightly above.
Figure 2: Overall dimensions
❑Make certain there is suffi-
cient space behind the instru-
ment panel to accept the ST700
Dash Display System display.
Allow additional space so that
you may run and connect the
wiring harness without the
need to apply sharp bends to
the harness.
Figure 2 shows the overall dimensions of the ST700 Dash Display Sys-
tem display, which fits into a standard 80 mm diameter hole.
Wiring Harness
Stack supplies a wiring harness to connect the ST700 Dash Display Sys-
tem within the vehicle. If you find that the standard wiring harness is
unsuitable for installation on your particular vehicle, contact Stack or an

Installation ST700 Dash Display System

approved Stack agent for details of wiring harness extensions. Labels
identify each wire in the harness shown in Figure 3.
1. Identify all the relevant connectors of the wiring harness.
2. Plan the location of all the component parts of your ST700 Dash Dis-
play System and decide the best layout to use when you install the
wiring harness.
Note that your installation might not use all the cables that exist in the
harness. You should tie back and protect all unused connectors.
3. Begin at the instrument panel where you will install the ST700 Dash
Display System display. Lay the wiring harness into the vehicle,
with the cable branches running to their appropriate locations.
Allow sufficient slack in the harness so that you can connect it to the
ST700 Dash Display System before you insert the display into the
instrument panel.
You should route all cables to be no closer than 75 mm (3 inches) to
the ignition HT leads or the distributor cap. Do not run cables close to
sources of intense heat.
4. Fit cable glands to protect the cables where they pass through bulk-
heads or panels. This is particularly important when you pass cables
through carbon fibre partitions, which can wear through them eas-
ily.

1. Connect the wiring harness to the ST700 Dash Display System dis-
play. There are two connection ports on the back of the display, but
you can insert the 8–way connector only into one of them. Do not
try to force the connector into the incorrect port. Tighten the lock-
ing collar by hand. The second, 6–way, port allows you to connect
the optional pressure and temperature sensors and an optional data
logger module.

2. Fit the ST700 Dash Display
System display into the
instrument panel using the
supplied O-ring.
3. Reach behind the instrument
panel and position the secur-
ing bracket as shown in Fig-
ure 4. Tighten the lock nuts to
fix the ST700 Dash Display
System display into position.

Controls
The ST700 Dash Display System includes three controls:
❑Driver button—this is a normally–open spring–loaded switch that
closes when pressed and opens when released.
❑Rotary control—this is a combined push button and rotary selector.
❑Lap button (optional)—this is a normally–open spring–loaded
switch option that closes when pressed and opens when released.
For convenience, you should install the controls where the driver may
operate them easily. An ideal installation for the Driver button and for
the optional Lap button is on the steering wheel within easy reach of a
thumb.
Install the rotary control where it is possible to operate it conveniently
while viewing the ST700 Dash Display System display.
1. Drill holes or install brackets to support the controls in the locations
you have selected for them. The hole dimensions and tightening
torques are:
Rotary control: M7 clearance (7.2 mm diameter) with the control
tightened to 1.2 Nm (12 kgf.cm or 0.9 lbf.ft)
Driver button: 12.2 mm diameter with the control tightened to 1.5
Nm (15 kgf.cm or 1.1 lbf.ft)
2. Connect the correct cables of the harness to each control.

Engine Speed Measurement
This connection is dependent on your ignition system. You should
read these instructions carefully and make certain you have identified
the correct connection point before you begin.
To measure engine speed you must make the correct connections be-
tween the ST700 Dash Display System and the vehicle ignition system.
Contact Stack for advice if you have a complicated ignition system.
If you cannot use any of these engine speed connections, you may use
the optional Stack ST697 HT pick-up to get a signal from an ignition
lead.

Standard contact breaker system
Connect the ‘ES’ wire of the harness to the negative contact breaker ter-
minal on the coil as shown in Figure 5.
Electronic ignition connection
Connect to the electronic ignition of the vehicle as indicated in Figure 6.
If your ST700 Dash Display System includes the Lap Timing sensor, the
Wheel Speed sensor or any pressure or temperature sensors, follow the
instructions between page 16 and page 27 to install them. Otherwise,
turn to page 27 for instructions to connect your ST700 Dash Display Sys-
tem to the switched battery circuit of your vehicle.

Lap Timing Sensor option
The lap-timing sensor triggers the ST700 Dash Display System automat-
ically each time the vehicle passes the Stack infrared (IR) beacon at the
side of the track.
1. Choose a location on the vehicle for the lap-timing sensor:
Figure 7: Lap timing beacon
❑You must position the sensor
to be horizontal and square
to the vehicle axis.
❑It must have a clear view of
the trackside beacon, even
when you overtake or are
overtaken by other vehicles.
❑Do not mount the sensor
behind glass or Perspex.
❑The sensor must be at the
same height as the beacon.
As shown in Figure 8, you can
adjust the height of the beacon to achieve this condition.
