G-class pneumatic seat adjustment cabling
I would like some help with W463 pneumatic seat-
The air pump is not getting power! I don't have the correct wiring plan, from where can they get 12V? On the connector has ground (braun) signal (smal green) but the 12V on red Idont' found. Where should you get power from? Vojnó

In order to be precise, the ideal is to have the VIN and thus be able to know who provides the electrical power.

Check pin 5 (Red), it is also 0.75mm section, there are only 3 of that section. It is fed from fuse 13 of the rear SAM.

Yes, the Red/white I have it on pin5 but no power on it! Where does this come from? The fuse 13 is ok and have 12V but on the pump motor nothing. Does anyone switch on this? Vojnó

RE: G-class pneumatic seat adjustment cabling
Fuse 13 feeds both seats so if it only fails on one and you don't have 12v on pin 5 the problem is the wiring, from the rear sam to the air unit there are 2 or 3 junctions.

In the diagram that I have found there is no 30, that unit only receives power from terminal 15, tomorrow I will share it with you.

That vehicle is from 2009 and I imagine that what is wrong is the adjustment of the lumbar support, right? if so, your schema is as follows:
