Does Anyone Know the part No. For the small W211 Command Harness

Have any of you guys retro-fitted your W211 Command and can remember the small wiring harness part number. I will also need the fibre optic cable part numbers aswell if anyone can remember

I have got the high end unit
Navi drive
Antena with extension cable
Brackets for rear left trunk

Fibre optic cables and the "know how"
