An extension cable for a BlueFire 9-Pin Adapter.
This allows you to move the BlueFire Adapter to a different location other than where the diagnostic port is. Very handy for vehicles with rear mounted engines.
Note that if you have a BlueFire Black Adapter you need a Black extension cable.
There are many locations where you can purchase this cable. Just search for J1939 Extension Cable. Amazon has an extension cable for the Green adapters at this link and Ebay has one for both the Green and Black adapters at this link.
