V40 CD Changer Cable

[Dave Reader]

Hi,

I've a 2002 V40 (UK spec, if that matters), which does have the CD
changer cable present behind the head unit.

I can't find the other end, though. Where should I be looking?

Does the cable being present behind the dash mean that it is fully
pre-wired for the changer, or did they do something strange like cable
only part way?

Thanks in advance,
Dave.
