Fibre Optic Cable to CD Changer (custom install?)

I have a 2005 ML350SE which came with an Audio 10 CD head unit and no CD changer. I recently purchased a 2001 ML430 and I have already moved the Comand 2.0 head unit, Bose amp (non fibre optic) and Bose subwoofer from the ML430 across to the ML350SE and these are all working perfectly.

I also wish to move the MB CD changer from the ML430 across to the ML350SE. I have checked the ML350SE very, very carefully and there is no fibre optic cable pre-wired from the head unit to the rear compartment where the CD changer installs, although the wake-up wiring is pre-wired. So to install the CD changer I need to purchase and install a new fibre optic cable.

The Audio 10 CD head unit (now removed, replaced with Comand 2.0) had/has a fibre optic cable plugged into it, and as far as I can tell the other end is connected to a UHI telephone controller (I think this is what it is called) .... which is a black plastic box mounted on top of a plate under the driver's seat (see photos here).

I gave up trying to remove and reuse the optic fibre cable from the ML430 .... it's quite a major job.

My questions are :

1. Can I "break" into the fibre optic ring under the driver's seat (Australian car, so right hand drive .... same side as CD changer compartment) and route a new cable from here to the CD changer? (This would be much easier than running a new cable from CD changer to head unit).

2. If this is OK, should the UHI telephone controller (?) or the CD changer be the first component in the optic ring?

3. To "break" into the optic ring by swapping around fibre optic cables in the black plastic end fittings ... is it as simple as gently "splitting" the two halves of the end fittings, swapping the cables and snapping the halves back together?

4. Where does one purchase the correct fibre optic cables and connectors for this task (given length is non standard)? Do I need connectors or joiners?

Thanks in advance for all help

Just to close this out, I purchased a used D2B cable on ebay and installed it by breaking into the loop at the UHI telephone controller unit under the driver seat (RHD) and running this under the carpet, under the sills and to the rear trunk area and connecting it to the CD changer which I removed from my ML430 (which I will sell shortly). CD changer worked straight away - no need for dealer programming.

So I now have working CD changers in both my ML350s.
