And like the J1939 port the 500K CAN bus requires a 120 Ohm load if you have the ECM on the bench.

any tips on unlocking the ecm via bench harness. Have no issue connecting with v2. when I connect with a bd to unlock ecm I get an error. ((connecting unlock cable to j1939(yes can and j1939 have 120 Ohm resis.))
Which connector is this on? J1 blue? or J2 green?
Im guessing green, because pins 21/45 on the green connector had 120 ohms resistance across them, which would be terminated CAN ports.

many thanks to Ross and Paul
Green (C2) is the connector that has all the necessary bench connections, C1 has the J1939 connections for the BD unlocker.
