Dynon D6: What is Pin 16 (black) Unused GND for?

[hplevyak]

Guys,
I'm installing a D6 EFIS and need to know what pin 16 is for?

It's labeled Unused GND:Black 16 on page 2-2 of the manual.

Should I just cap it off?

Is this pin grounded internally to the D6 such that I could in the future use it for an AUDIO OUT ground or SERIAL GROUND?

Thanks,
Howard

All the black wires are internally linked & you can use it for those purposes.
