Help with D2B lead link for cd changer
 

I bought my 2003 s-type second hand and it would appear someone removed the cd changer or nav unit from the trunk prior to my purchase. I have obtained a cd changer and I think I've found the 3 pin electrical lead for the cd changer but I need to get a D2B fiber optic cable to split to the amp & cd changer from the mounting bracket head unit joiner.
Does anyone know where I can get one?
I see a nav unit one on e-bay but don't know if this is the same as the cd changer. JEPC lists link leads but they all start with XR... and I can't find an xref to a current part number. My Canadian jag dealer (Budds) says there isn't a separate lead and you can no longer get the complete wiring harness (not that one needs it).
Any pics of the connections in the truck would help also.
Thanks
