The easiest way we've found is to use the 2-wire jumper cable from the KoP (the first item on page 12 here). One end plugs into the 2-pin connector on the digital side car (right next to the power connection). The other is stripped and hooked up to the robot signal light. Gnd (or -) goes into the middle position, positive to both of the outer positions. Usually this means you have a small length of wire that goes from one to the other, with the lead to the side car going in one.

The light comes on once the cRio has booted up. When you first turn on the robot, it'll stay dark for about 10 seconds or so. By the time the driver station tells you everything is ok, the light should be flashing.
