Scale modeling I.V
I checked the mirror plugs and the switch, removed the pins from the plug, and it turned out that none of the local electronics or automotive shops had the ones I needed, and what they had barely fit. Instead of forever struggling with the wrong pins, I decided to buy the entire wiring harness for the left door and give it a new lease of life.
Now, just waiting for my vacation, and it should be possible to put everything together.
