I usually just acquire 20 or 22 gauge green/yellow, and use a drill to quickly twist them.

Although the colors may not be required, we highly recommend following the green/yellow scheme for the following reasons.
-Makes robot inspection and troubleshooting easier.
-The colors will match what's labeled on the roboRIO CAN connector
-The colors will match what's labeled on the PDP/PCM Weidmuller connectors.
-The colors match the Talon SRX cable harness.

It all adds up to a better CAN bus experience.
