What is the exact year and model on BMW you are working on?

Some quick general info:
The pressure sensor is 3 wires. It is located on hydraulic unit.
Power supply, ground and sensor signal.

The rotation sensor has 6 wires.
If I remember correctly it has two reference voltages, two sensor gound pins and two signal wires.

Once you supply the year and model I can try to be more specific.

Rotation sensor
For rotational speed, the sensor produces a reference signal of 2.5 volts and a linear voltage
signal from 0.7 to 4.3 volts. This linear voltage input signal is used by the DSC control
module as the degree of rotational rate (yaw).
The sensor also produces a linear voltage signal for the lateral acceleration (G-force) that
ranges from 0.5 to 4.5 volts. The DSC control module uses this input to determine the side
forces acting on the vehicle for DSC regulation.

Pressure sensor
The sensor receives its power from the DSC control module and produces a linear
voltage input signal ranging from 0.5 to 4.5 volts depending on how hard the brakes are
applied.
