The shipment just arrived and I have the "green mysterious thing" on my table.
It come without manual, when having the metal cover already press on the mushroomed pin, I see no way to insert cable ends in it. Also the gap in the slot is about 0.5 mm - not big enough for 1 mm cable. I called Autohaus for advice and CS promised a call back from the technician.
In another words it might not be as simple as it sounds. Stay tuned.

Edit. I got feed back from Autohaus. They claim to sell thousands of them, but have absolutely no knowledge how to install them. Would that make you wonder?
So the only way I can figure out how to make it working is to drill out the pin, hopefully insert the cable ends with springs in the slider and than worry how to reuse drilled pin, or find another one.
I still have more concerns, that can't answer till I try to use it, what hopefully will not happen soon. The green slider has the pivoting piece mounted centrally, what makes it working for right and left window. The sliders I had pulled from the junk yard had the pivot off center and left was mirror view of the right one, meaning they will not close the other side completly (like I experienced playing with my repair the hard way).
