Going to rewire most of the can-related components at VCU. We were using 6 conductor wire. Going to switch to two. 120 ohm terminator soldered to wire not crimped.
We used 6 conductor wire, but we used 100ohm resistor as a terminator instead of 120ohm. I have heard second and third hand reports that using 120ohm terminators create issues, so I would try that before rewiring the entire CAN bus.

In the "Getting Started Guide" on Page 29 for the Black Jags the section "Jaguar Communication Cables" states 100ohm. Also see Table 8-1. CAN Wiring Parameters on page 26. http://www.luminarymicro.com/jaguar
