Relay Output on Orange Cube - need help

CubeOrange Arducopter 4.5.6
I measure the + (Red) and - (black) pins, 0.0V, and measure S (Signal) and - (black), 0.0V. Main out + pins (1-6) are currently open, and not connected to ESC.

Do I need to supply external power (5V/ 3.3V) to Main Out + pins? Something like that?
Is the servo rail in the article referencing Main Out + pins? What about AUX power referring to?

I am concerned about burning the CubeOrange (not a cheap board).
I am still confused about the entire Power Architecture.
