It seems to me that a short between the two wires will be the most likely failure mode in the new system. We have diagnostics that report roboRIO's CAN TX overrun which should catch long to intermittent shorts.

Of course the Talon SRX has no Weidmuller connector, so Talon to Talon will just be twisted or soldered or some custom connector. would be good if there were a Weidmuller block created that allowed a bunch of them to be all connected.
