1Purpose, construction and operation of the GC90Ci
1.1 Purpose of the GC90Ci
The purpose of the GC90Ci is to automate your speed management.
1.2 Construction
The GC90Ci 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);
programmer (available by download, ask your supplier);
programming harness (order separately);
installation manual programmer (available by download, ask your supplier).
specific components:
specific T-harness (order separately);
specific installation manual T-harness (supplied separately or by download,
depending on delivery option).
Depending on the modular supplies or the vehicle, more or less components are
applicable. Contact your supplier for more information.
1.3 Operation
The GC90Ci GoldCruise consists of a compact EM, that’s 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 GC90Ci
GoldCruise or speed limiter can make optimal use of the available engine power.

2Safety directions
To ensure safety the GC90Ci complies with the following labels.
For the GC90Ci the following safety instructions apply, also printed in the item it
concerns:
Only use the GC90Ci for the purpose as described in this installation manual
The installer of the GC90Ci 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 GC90Ci malfunctions
and indirectly affect road safety
Never alter or manipulate a GC90Ci. Alterations or technical manipulations
made to the GoldCruise products can affect its safety adversely

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, etc.)
Always use a multimeter when measuring on the vehicle
Cut wires to size, keep them as short as possible
CAN-wires are twisted to assure a reliable operation. Make sure that the
twisting remains the same when the CAN-wires are shortened or extended
As the GC90Ci is supplied model specific, it is not necessary to learn the
accelerator pedal and speed signal. The GC90Ci will operate directly after
installation, unless indicated otherwise when the unit was programmed

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, etc.)
As the T-harness is model 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
CAN-wires are twisted to assure a reliable operation. Make sure that the
twisting remains the same when the CAN-wires are shortened or extended
As the GC90Ci is supplied model specific. Connect the wiring harness as instructed in the
supplied specific installation manual.
Connect the universal wiring harness as follows:
orange wire
connect to an ignition switched feed (+15), preferably directly after
the ignition switch
blue wire
(twisted pair)
connect to CAN high
blue/white
wire
(twisted pair)
connect to CAN low
8-pin connector
Connect to the 8-pin connector of the CM, also refer to the
installation manual CM
4-pin connector
do not use

Before using the ML90Ci Multi limiter should be released. Hereby the
ML90Ci checks or the CAN-bus signal for the brake is stable
As the GC90Ci is supplied model specific, it is not necessary to learn the
accelerator pedal and speed signal. The GC90Ci will operate directly after
installation, unless indicated otherwise when the unit was programmed
i
Re-connect the negative battery terminal and remember to set the lost
volatile data (audio, board computer, clock, etc.)

The GC90Ci is supplied make/modelspecific with carefully selected settings. Yet there is
the possibility that the chosen settings are different than the required settings.
In that case it is possible to learn the accelerator pedal and speed signal manually:
refer to § 4.2 The CG90Ci accelerator pedal set-up
refer to § 4.3 The GC90Ci vehicle speed signal set-up
Check during the test drive (§ 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

4.2 Release procedure
The GC90Ci is secured with an release procedure, this procedure checks if there is a
proper CAN-bus brake signal available and properly programmed. The Cruisecontrol
askes you with beep-signals to press and release the brake pedal. This procedure needs
to be performed once after installation.
Read this procedure carefully before performing it.

When the Cruisecontrol isn’t released, do step 1-6 again before contacting your
supplier
When this release procedure isn’t done correctly, the Cruisecontrol doesn’t operate, it is
however possible to:
-Learn the accelerator, learn the speed signal (not necessary with GC90Ci)
-Do the self-diagnostic
-Use the speed limiter (when programmed)

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
