I took apart (rather roughly) my cradle to extract the sharp I/O connector for the Z...

I'm now at a loss as to what my next steps are in terms of disassemble...

Above is what the back side (opposite side of the sync button) looks like, below are the labels and some of my guesses about what is going on...

The pin out from the board into the plug at the top has 16 pins...
The pin out to the middle socket appears to have 18 lines...
I'm guessing that it is the 16 pins for the Z +2 for power?

Does anyone know for sure?
Should I be creating a new ribbon to run to the middle socket?
Should I take the top plug off and wire what directly to my serial port plug?
