Raskull, I am in the same boat. I was sold a BBK, it doesn’t make things quite so plug and play. I researched the adapter mentioned above, I may bite the bull it and do it with another TB. I thought I had a solution for the bbk a few months ago. Turned up false. In Afghanistan right now, so have to wait about two months to wrench more.
