Connection
The four stepping motor windings receive a common B+ feed from ACC unit pin 41 (K42) and grounds each corresponding winding (pin 12, 33, 13 and
32 in K42) in a specific order thus operating the motor in short pulses, which explains the name stepping motor. The rotational direction can be changed.
