The pinout in the mentioned thread is for an ULF, not for a TCU. I checked the wiring for ULF, its slightly different to TCU but only minor changes.

I did not change the eject box wiring, as I changed the eject-box wiring at the TCU. Even though i donīt think an eject-box is necessary to start the TCU. I think, and i could be false here, that the TCU should be recognized by the vehicle just with 12V, ground and Ibus?!

Can anyone confirm this point?
