I hope I’m posting this in the correct place! I’ll make this as short as possible. I have a 1995 mint condition 9200 with an M11. It was manufactured 7/1994. I’m having issues with a connection somewhere behind the ecm in the wire loom. I’ve spent 20 hours trying to find it. I have two repair manuals from Cummins one from 1993 and one from 1996 and it seems that neither wire diagram matches the pin outs in my truck. My ecm p/n is 3084473-RX. All I need is the wiring diagram even if only for the plugs on the ECM I’d be grateful. Can anyone help? Going to make another trip to the local dealer tomorrow to see if they can help any further. Pretty much been told to tow it in and let them fix it but I’m pretty capable, a tightwad and also pretty determined I just can’t find the correct schematic!

If you connect insite to your ECM it should tell you the CM number for the ECM
and harness. Cummins has some very nice laminated wiring diagrams
available as well.dustye36 Thanks this. -

It sorta depends what your specific problem is. There are two different wiring systems there. One is 100% Cummins, the engine harness, and other is International which is the OEM harness. If you are having sensor or injector code type of issues, this is the engine side. Like mentioned, get yourself a free Cummins Quickserve log on and you will get access to their engine side wiring diagram. If you have problems related throttle pedal, cruise control or engine braking, then you would needed International OEM wiring diagrams. If you call any dealer, remember, they are a business trying to make money. Giving away free information isn't something they are willing to do most times. Wiring diagrams for your truck were all paperback back then. It's all online for us now and most stuff pre 1999 is hard to access. I don't know if those books are even in print anymore. You could try to calling your dealer's parts department to see if they are still available.

Brings to mind a funny story. There used to be a micro fish program to look up parts. It used small cards on a projector screen. A old man in the back was on one of those. New guy was up front and answering every call ASAP plus taking all the counter customers. Gotta get all that commission money I suppose. Phones on hold had cords on the hand set laid on the counter. He did ask what I needed between the ping pong work between customers. The old man left his screen and walked through the doors to the part room. He walked so slow I felt bad for him. After a while he came back and walked up to the new guy. Laid my parts on the counter, pulled out his old pocket note book and told him the part numbers. Then walked back to his fish program.Heavyd Thanks this. -
Yes, I remember those machines. The film cards were about the size of a post card and had tons of information on them. I remember there must have been 100's of them.
