[Balloon] J140 Connector C Questions

Hi,

I can't tell from the schematics if the lines on the j140 "C" connecter
actually go to the power rails on the board? In other words, if I take the
power supplies on my mother board, can I feed power to the Balloon board
through this connector? Normally, I would assume we are feeding power off
the balloon to auxillary components through this connector.
