It is NOT the same connector. The only parameter it shares with the JAE
connector is pin pitch (0.039"). I have spent a lot of time searching
manufacturers for this item to no avail.

Pin 26 - ProdDockAttach - tie to ground for wake up.

Waste of time.

If you gotta mod it, it wasn't meant to fit in the first place.

Uggh!

See above.

Look, if you can wait till Jan then I will have audio dongles available that
use the CORRECT connector. (Don't ask about the source, I can't reveal that
but there will be enough to go around)
These dongles will be professionally made and have additional features not
found on other audio dongles to date. (Ooo! what could that be???)
Details will be available on my website when they are ready.
I applaud your inventiveness Brian, but you are risking a NI disaster by using
these Molex parts.
