I tried to replace the lens motor but I accidentally cut the cables of the M/A switch.
The cables were originally connected (if I remember well) on the pins 1 and 2 like the 1st photo I found googling it. Ok, I soldered them in this way, but I had always autofocus A/M (no manual mode, even I've switched to M mode).

I got some quick connectivity switch position meters and it seems that the switch between pins 1 and 2 is always open circuit as well in all other combinations except only pins 1-3 when it is switched to M/A mode, otherwise is open circuit.
So, to summarise, all pins are open circuit EXCEPT pins 1-3 when only M/A mode is selected.
I tried to solder pins 1-3 like the captured photos and now I get a reverse effect where when the switch is in M/A I have no autofocus (manual mode) and when the switch is in M mode I have autofocus.
I am pretty sure that the correct connection is pins 1 & 2 but this does not seem to work since I have always autofocus.
I am confused about how this switch actually works. In my option, it should work like when A/M mode, pins 1 & 2 should have a short circuit and when the switch is moved to M mode pins 1 & 2 should have an open circuit as a state change or in a reverse way. What do you suggest? How this switch work?
