  1. I knew they were identical motors so to speak. I had a customer call me to get his truck running, he put a 17 model d13 in his 2012 mack. It wouldn't run with the mack ecm but it runs with the vovlo ecm. He is having it deleted and the guy doing that told him he has to change the engine harness to run the mack ecm. I find that yard to believe they would build 2 different harnesses for the same engine. I know the ecm strategies would be different based on how the engines sound while running. I remember when the mp7s first came out all the parts I got from mack said volvo on them.. Thanks for the feedback
  2. Just curious if anybody has used a d13 in place of a mp8 or d11 in place of a mp7 and vice versa? I know the base of them are the same and ecms are different. But wasnt sure if there was more that is different to not be able to use one? Thanks
  3. Ecm was bad swapped it out with another now it runs.
  4. Yes thats what this truck is. Build date 3/07, First mp7 i ever seen with only a egr for emissions on it. Mack dealer will not help with schematics or fuse/relay diagrams. Says its against company policy The truck cranks but will not fire off. Im not sure what wires need power and ground. Could be the ecm is gone, but with out confirming wiring i dont want to throw an ecm on it. Tech tool is no help either, It tells me to check fuse 38 or it has a short to ground. Doesnt give me any thing more than that. ive been diggin everywhere i can think of for schematics and come up short.
  5. I got a truck with a mp7 epa04. im looking for the ecm interface plug pinout. It has the small 16 pin like a e7 engine and all the diagrams i have from mitchell and on motor are for the newer ones with the bigger interface plug the pugs in above the ecm. Thanks
