The ports are all mapped out in the DANA CTIS "TM".
The orange circle is what I wired today, both J1708 and J1939. The red arrow is pretty much what we are not happy with. The wiring harness on the truck side didn't have any of the diagnostic ports wired, so we are doing it.
You can see "a" and "N" are the J1708 and the "A" and "D" pins are the J1939. The ports below are the wiring harness and the component connector. My earlier pict is inside the ECU, so it pretty much just like the wiring harness. Remains to be seen if the ports are actually active, which one, and what information it will give out. Hoping for J1939, but J1708 is still out there.
I did find a DIGI wireless J1708 wifi adaptor that plugs into the Deutch 9-pin connector that would be cool to do, had our trucks have it connected, and integrated into the other systems. I think there is more that our trucks can tell us than we think. After the CTIS thing, I might check into the truck diagnostic port to see if our engines are telling us anything.
