lincpimp: No problem. I have a couple of these adaptors (2s+2s) that I use myself so I know they work.
nativepaul: Glad to hear you got it all squared away. The way I made the wiring diagram protects the cells if you happen to plug them into the wrong part of the balance Y adaptor, the worst that will happen is that the bakancer won't recognize the pack right.
As to the wiring of the data port, I imagine it uses a typically wired servo type cable, but not sure.
