Hi - I input your VIN into my WIS and the same circuit diagram came up for "diesel injection system with in-line pump (IFI) and electronic control.
It is confusing because I expect your wiring to follow the circuit diagram. You could double check by following the wiring between N3/7 and X26/2. It doesn't matter what the wire color is, or the pin used is, provided the right connection is made.
In other words, do N3/7 pins 23 and 4 go to B11 coolant temperature sensor?
The VIN is not very informative (for early MBs) but I see you have A/C, Manual transmission, Anti-theft system, delivery 22/05/1995 Africa.
I hope that you can sort out the problem.
