Pin	Function
1 (tip)	Trigger
2	Focus
3	n.c (there is only 3 wires in the cable!)
4	GND

Hama DCCSystem pinout (2.5mm jack - 4 poles)

Pin	Function	Color

Handwork

1. Open the foot pedal switch, remove the existing cable
2. Cut the extension cable, the interesting part is the female one.
3. Solder the green and red wire together then to the first pole of the switch in the pedal.
