^ The Twisted circuits shall have a minimum twist rate of 3 twists (4 wire crossovers) per 50 mm. One
"twist" or "turn" = 180 deg. Rotation. Twisting shall be maintained to within 50mm of any in-line or
component connector.
The twisted pair that forms the CAN Bus shall be
twisted throughout the total run of the vehicle
except for a maximum of 50mm from connectors
or harness splices. At splices an additional 50mm
of untwisted wire is allowed between the CAN H
and CAN L contact points
