1Purpose, construction and operation of the GC90
1.1 Purpose of the GC90
The purpose of the GC90 is to automate your speed management.
1.2 Construction
The GC90 is part of a Cruisecontrol-kit that consists of:
universal components:
electronic module (EM);
command module (CM) (order separately);
universal wiring harness;
general installation manual;
user manual CM (included with CM);
installation manual CM (included with CM);
clutch switch (optional)
specific components:
specific T-harness (order separately);
specific installation manual T-harness (included with T-harness).
Depending on the modular supplies or the vehicle, more or less components are
applicable. Contact your supplier for more information.
1.3 Operation
The GC90 GoldCruise consists of a compact EM, that is connected between the
electronic accelerator pedal and the engine-control–unit (ECU) of the vehicle.
The EM “manipulates” the ECU and controls the relationship between the driving speed,
throttle valve position and fuel injection time. The manipulation occurs by varying the
output signals of the accelerator pedal. This means that the signal structure in the ECU is
not altered at all. Because the accelerator pedal is learnt to the system, the GC90
GoldCruise or speed limiter can make optimal use of the available engine power.

2Safety directions
To ensure safety the GC90 complies with the following labels.
For the GC90 the following safety instructions apply, also printed in the item it concerns:
Only use the GC90 for the purpose as described in this installation manual.
The installer of the GC90 should have technical knowledge of modern cars
and be experienced in working on them.
Incorrect and/or ignorant installation, connection, adjustments and/or
diagnostics can lead to vehicle and/or GC90 malfunctions
and indirectly affect road safety.
Never alter or manipulate a GC90. Alterations or technical manipulations
made to the GoldCruise products can affect its safety adversely.
Inform the customer whenever no clutch protection is installed.
Point out that the GC90 will not disengage when depressing the clutch
pedal. John Gold advises always to install a clutch protection (if applicable).
Connect the “twisted pair” brown and brown/white wires in such a way
that, with the brake pedal released, one wire has +12V from the brake light
fuse and the other has ground through the brake lights.

Cruisecontrol GC90 installation manual

Always solder the connections and insulate them with vulcanizing tape.
Always install the EM in a position where heat, vibration and moisture are
minimized, such as underneath the dashboard.
Undo the negative battery terminal before working on the vehicle.
Loss of volatile data is possible (audio, board computer, clock, etcetera).
Always use a multimeter when measuring on the vehicle.
Cut wires to size, keep them as short as possible.
Use a fuse of up to 3 Amps.

3Installation and connections
3.1 Installation electronic module (EM)
Always install the EM in a position where heat, vibration and moisture are minimized,
such as underneath the dashboard, never in the engine compartment.
The installation kit contains tie-wraps, double-sided tape and screws that can be used to
install the EM.
Always install the EM in a position where heat, vibration and moisture are
minimized, such as underneath the dashboard.

3.3 T-harness connection
Undo the negative battery terminal before working on the vehicle.
Loss of volatile data is possible (audio, board computer, clock, etcetera).
As the T-harness is vehicle specific, it is supplied as a separate component.
Read the accompanying installation manual carefully.
Connect the T-harness as follows:
Connect the 8-pin black connector of the T-harness to the 8-pin connector on the
EM;
Undo the accelerator pedal connector and connect it to the T-harness;
Connect the T-harness connector to the accelerator pedal.
3.4 Wiring harness connections
Always use a multimeter when measuring on the vehicle.
Cut wires to size, keep them as short as possible.
Connect the universal wiring harness as follows:
orange
wire
connect to an ignition switched feed (+15), preferably directly after the
ignition switch;
i
For many European car-makes it is possible to connect the orange wire to
the feed wire of the brake lights (along with the brown/white wire).
This is only possible in case the brake lights only operate when the ignition
is switched ON.
brown wire
connect to the wire that is connected to ground via the brake
lights, this becomes 12V when the brake pedal is depressed.
In case a relay is used in the brake light system, connect to the wire that is
connected to the brake lights directly;
brown/
white wire
connect to the fused feed wire of the brake lights, before the
brake light switch;

Cruisecontrol GC90 installation manual
10
Connect the “twisted pair” brown and brown/white wires in such a way
that, with the brake pedal released, one wire has +12V from the brake light
fuse and the other has ground through the brake lights.
2-pin
connector
if an original clutch switch is available, connect the violet wire
to the switching wire of the original clutch switch that switches to ground or
from ground when the clutch pedal is depressed. In this case the
green/white wire is not used. If an aftermarket clutch switch is used
connect the 2-pin connector to the clutch switch;
blue wire
connect to the vehicle speed signal wire.
Refer to the wiring diagrams of the vehicle;
yellow
wire
do not use. Cut off at 10 cm from the connector and insulate, unless
indicated otherwise;
8-pin
connector
Connect to the 8-pin connector of the CM, also refer to the installation
manual CM.
First learn the GC90 to the accelerator pedal and the speed signal, before using the
Cruisecontrol. Refer to chapter 4.0 Set-up.
i
Re-connect the negative battery terminal and remember to set the lost
volatile data (audio, board computer, clock, etcetera).

First learn the GC90 to the accelerator pedal and the speed signal, before using the
Cruisecontrol:
refer to § 4.2 Accelerator pedal set-up;
refer to § 4.3 Vehicle speed signal set-up.
Check during the testdrive (§ 4.4) the response time and sensitivity of the cruise control.
Only adjust the response time if the Cruisecontrol engages too slowly or too
aggressively:
refer to § 4.5 Increase response time;
refer to § 4.6 Reduce response time.
Only adjust the sensitivity if the Cruisecontrol reacts too forcefully or too slowly while
cruising:
refer to § 4.7 Increase sensitivity;
refer to § 4.8 Reduce sensitivity.

Some accelerator pedals do not have consistent signal values near the full
travel area (presence of a full throttle switch). Therefore the pedal set-up
may fail.
If at step 9 the beep pulsates high/low the pedal set-up failed.
In this case repeat the pedal set-up, but only press the accelerator pedal to
95% of its full travel at step 8.
