Signal generator for a digital speedometer signal.  The 4P module generates 4 electrical pulses per speedometer shaft revolution. With a k-number of approx. 1000 (T3-Syncro, Golf2, etc.) this results in 4000 pulses per revolution.  2WD speedometer: W=500 ⇢ 500 speedometer shaft revolutions per km ⇢ with 4P module ⇢ 2000 pulses per km 4WD speedometer: W=1000 ⇢ 1000 speedometer shaft revolutions per km ⇢ with 4P module ⇢ 4000 pulses per km Golf MK2 speedometer: W= 960 ⇢ 960 speedometer shaft revolutions per km ⇢ with 4P module ⇢ 3840 pulses per km Depending on the control unit/signal processor unit used, a tachometer signal can be generated with 5V or 12V. Via a solder bridge, the signal voltage can also be adjusted subsequently.
