Greetings, gentlemen. I am now in the process of replacing the engine from m47n to m57. The body side connection is a more recent kind, often referred to as a single large connector.
The m57 ecu uses a compact, outdated generation connection. (Comparison between a 5-connector ECU and a 2-connector ECU)
I possess wiring diagrams (WDs) illustrating the pin configurations for both electronic control units (ECUs). However, I had difficulty in determining the appropriate placement for the voltage supply pins and ground pins. Additionally, on the m57 side, there are pins for coolant temperature, oil temperature, and other parameters. However, I am unable to determine their appropriate placement or connection on the m47 side.
It would be much appreciated if any of you could provide guidance on the correct placement of the remaining pins.
