But i cant find the pin out list for this.

The circuit diagram shows connector numbers, and also shows the connector pins, wire colour, wire size and wire function.
Just click the connector number for a full table.

Where can i go from here? The only pin out i can find for BIT2 is X4038

Thats all the info you need.
You see the wiring and signals of the existing BIT2
You see the wiring and signals of the wanted new TCU
Simply transfer the relevant wires from the old to the new
Of course, some will be no longer required, and you may need to reassign some wires running from phone to the eject box.
But it is pretty straight forward.
Work in this order:
Ground
Ibus
Power
Microphone
Audio Out
Eject Box
SOS switch (if fitted)
That's all you need.
