It actually is not as complicated as it can seem at first. It is a set of wires that carry data.

dougmac,
On the back of my MMDC, the controller for the annunciator panel and all the gauges is a 24 pin connector and a 10 pin connector. Among all the wires that are entering the back of the plug to the 24 pin connector are two that appear to be the J1939 wires. They are green and yellow and are twisted. I got that far. But, from there, they travel deep inside that loom and go to who knows where.
If I were at home, in my own environment, and didn't have WIND BLOWING THE PAINT OFF THE RIG as it's almost been doing for the past three to four days, I'd do more to take this project on.

This will be the FIRST TIME I've EVER had to PAY for someone to fix MY RV!!!! Boy, does that suck! I've got an appointment with Freightliner tomorrow morning at 08:00 to get this thing in there and see what they can come up with.
