If you want to run a 5V fan all the time, just grab a red and black wire off the power supply and do it that way.

If you are talking about the two pin connectors, there should be two of them, labeled on the schematic as Aux Power connectors.
One will provide 5 Volts, the other will supply the voltage equal to the input voltage (normally 12 volts). As far as I know you
cannot control these Aux power connectors from the firmware, they are always on. They can be used for a 5 volt fan the other
for a 12 volt fan but these fans will always be on when the Rambo is powered.
The Rambo wiki is here:

Or do what Gene said with a yellow wire instead of red.
