WTD: Volvo connection cable (Volvo Headunit to Volvo CD Changer)

[Mark]

I am after a connection cable to connect my Volvo head unit to my
Volvo CD Changer in my 1998 V40 as my car did not come pre-wired.

I'm willing to pay a reasonable price for this cable.

Also does anyone know where the changer unit is fitted when it is
factory installed. Is it on the left hand side of the boot in the
recess?

Thanks

Mark
