It was a lot of work to wire everything, especially because I didn't have a proper wiring diagram.
And I think wouldn't do it again [emoji3]

No the engine and the gearbox were not damaged The only thing broken was the oil filter housing and...
Thanks for the info,
I've already swapped the engine and it's running perfectly.
The communication between engine ecu and transmission ecu works without problems.
All important data such as throttle position and enginespeed are recognized by both control units.
Why do I need the transmission from the A1?
The Allison 3070SP also works together with the WTEC III Controller on the CAT C7
The ECUs communicate via J1939 and both can do that, so I don't think it's necessary to install the Allison 3700SP.
thank you for your help.
The engine is from a 2008 M1093A1R with 350HP
I tried to trace the cables.The cable with the yellow sticker is the supply for the control unit and the other cable leads from TL 110 to TL 112.
If I want to start the engine I have to connect the cable TL 111...
The cables are located on the left side of the engine.The TL 110/111 cable comes from the plug on the engine control unit and is approx. 6ft long, the TL 112 cable is approx. 2ft long.
I can also take a picture if that helps you.
I'm about to change the engine on my LMTV. From a 3116 to a C7
I noticed that there are 3 cables on my engine that don't show up in any wiring diagram.
The cables have the numbers TL 110/111/112.
Maybe someone can help me out and tell me where they need to be hooked up.
