SL/R230: Looking for pics of facelift2-steering wheel/airbag

I'm looking for pictures of the backside of a facelift2-airbag (>2008).
I am particularly interested in pic of-
- Multifunction switch blocks
- How many wires are pluged in a switch block
- MB part# of the switch blocks
- MB part# of steering wheel control unit
- how the board of th steering wheel control unit looks like
If anyone has pics or is able to do some pics, I'll be very pleased.
Thanks in advance.
