The relay outputs are "FWD" and "REV" rather than "S" and "+5V" for White and Red Respectively. As such, the White and the Red each carry a voltage with respect to ground for their respective directions. I counted on that voltage remaining close enough to 5V to operate the Arduino's digital input (I believe 3V is the minimum necessary).

Re: Arduino - RoboRIO Question

Not on the relay outputs! On the relays both the red and white wires are outputs and drive +5V to the spike.
