Extra-long power cable for MR-CANHUB to PDB connection.
These cables connect to any of the 4 pin Pout connectors on the PDB. All Pout connectors are the same, but some may be closer and provide a better location. Choose one that makes your wiring tidy without overstretching the cable.
And the other end connects to the power input (AKA VBat) of the MR-CANHUBK344
