Did you try this?
Try connecting a multimeter to one of the j1939 data link pins in the data port and the other to a good ground. The reading should be infinite. Then start moving the harness and see if the meter display start jumping around. on some trucks International ran the wiring harness on the outside of the frame on the left side just behind the steering axle. The harness would wear on the left front ABS modulator valve.
Put the meter on the floor where you can see it and keep poking at the harness.
