This is for a new Kenwood TK / NX / EFJ VP6000/8000 portable key load adapter.These will not function as an audio adapter as they have been modified to function strictly for keyloading.

These have all been tested to work with the KVL 4000 and 5000 as well as the KFDTool or KFD shield variants out there. I personally test each unit before it ships.
