The speed limiter is controlled by the TCU.
The Euro box does not have the no.1 sensor on the front diff, it is in the box along with the no.2 sensor.
The no.1 sensor is on the output shaft at the rear of the box, used to detect road speed.
The no.2 sensor is on the parking gear, that is connected to the front wheels. It is used to do the normal functions, checking for wheel spin, and as a back up to the no.1 for speedo use.
The speed control function is performed through the Torque control, which is held low.
