If you've got a few hours, I'd recommend watching the videos above. I think you can find the Spikes in the WPI Robotics Library under "relays". You'll excuse me if I'm mistaken, I don't have LabView on this PC here at home. Either way, it's in the Robotics Library somewhere. Make sure you get the Open and the Close, and set the right channel for the spike in the code.
If you're going to be in Pittsburgh by any chance, we'd be happy to stop by.
