I have a 2007.5 Cummins MT 6.7 I am working on getting the engine wiring sorted out.
How have you gotten then OBDII port hooked to the ECM. The port has a Batt + wire, 2 grounds and CAN BUS + and CAN BUS -. The CAN BUS wires go to the TIPM before going to the ECM. Can the CAN wires be hooked directly to the ECM and it will communicate to the ECM without using the TIPM?
Below is a list of the wires and positions in the firewall chassis plug. I have it and the ECM in Excel if anyone needs it.
