VW CD Changer 

VW cable in the hatch area of a 1997 Jetta.  This car is a direct plug in for the Clarion changer, no adapter required.

Close up of the 13 pin connector, this one works with the Clarion changer.

The changer this works with is the Clarion CDC635 6 disk, we sell it for $290

hope this helps ....
