Grayhill Encoders: wire gauge + connectors

[Nemo]

Our team is playing with a practice drive, and we want to try the Grayhill encoders recommended by Vex on the ball shifter product page. DigiKey has them, but they don't carry versions with wires coming off. So we need connectors as well. The spec sheet mentions a Molex part# 14-56-3056 connector. That connector uses 26 AWG wire.

What wire gauge do we need to use for encoder wires? The 2013 rules, to the best of my ability to interpret them, don't specify a required wire gauge between sensors and a digital sidecar. Does that mean we'd be okay with 26 AWG under last year's rules, or did I miss a rule?

The Molex connector is not in stock at DigiKey, so I'm looking at this connector to connect to the encoder's pins.
