The gyro/acceleration sensor is specific to the system and should be mounted as
close as possible to the center of gravity of vehicle. The sensor should be assem‐
bled with the supplied damping plate. Position the sensor so that the connector
is pointing towards the rear of the vehicle.
Notice
Only use the provided kit sensor.
Use the damping plate.
Make sure the sensor is facing the correct direction (see image
above).

Sensor [} 47].
ABS Map Switch
While driving, the driver can use the ABS map switch to select different control
settings and find the optimum setting for his/her driving style. For this reason,
make sure the switch is mounted within reach of the driver. Many have found it
helpful to fit a diagram showing the current switch position, see also diagram in
chapter Features. The switch position is also broadcast on the CAN Bus so it can
be displayed with a dash (e.g. the DDU 9 and DDU 10 from Bosch Motorsport).
Notice
Only use the supplied ABS Map Switch.
Do not exceed the max. tightening torque of 1 to 2 Nm. Over-
torquing can damage the switch or make it difficult to turn.
Remove the front cover of the switch to access the retaining hardware.
ABS Warning Light (MIL)
The included wiring harness is structured in such a way that the power supply to
the ABS warning light (MIL) is branched off before the main switch for ABS M4
(terminal 30). This is the only way to ensure that the ABS warning light (MIL) is lit
when ABS M4 is not working.
Cable length connector to electronic board: 600 mm
Position the ABS warning light (MIL) so the driver can see it easily.
The MIL will stay illuminated in the following cases:
▪ ABS map switch is in the OFF position
