Assembling a Wire harness for a CAN Bus with 3 or more Oct 09, 2017For your wire harness you need to have a two-wire system with ~40 turns pr meter. You should connect any third unit on the bus in a “Y” connection with as short a wire as possible, making sure the 60Ohm impedance of the bus does not degrade too much. When connecting a third wire set make a mechanical connection rather than soldering it.
