Does anyone have the pin assignments for the yellow connectors under driver and passenger seat?

When I search in ISTA I can not find it there.
Pin assignment for FEM is easy to find but no matter what I search for I don't see it for X12*1B.

I also found no pin assignment, but a wiring diagram.
Maybe this helps.

Yes thank you, I have seen this already but I don't understand it completely.

I want to enable backrest width. I pulled one 2,5mm wire from Fuse 27 to pin 1 on both seats.
But when I turn the car on and check this wire it delivers no power to the seats. Am I missing some ground wire? From pin 2 perhaps? Not sure.

The earth points at pin 16 and 26 seem to be only needed for seat heating and seat adjustment.

This one shows a PIN 2 has to go to X642*1V which I think is on the back of the seat when you remove the back cover.
