I have a 95 M50 VANOS with a 413 red, dont know about EWSII though. thats greek to me, i know that you are to go-to guy about it though. Green sounds about right, but its a moot point now. OP has the motors DME so the issue now is getting it to match his OBC.

I am worried about the dashboard computer the most with respect to this swap.
The OBC for the car will only read as much as it has wires for., match them up and it will work just as it did with the M30. The extra wires coming off of the motor side are for further readings and sensors that the engine has that the car wasnt produced to display. Worst case, they dont get wired to the obc and those 5 wires dont get to display whatever information they provide.

I'll assume that the OBC has enough information to keep the motor in running shape as it has with the M30, things like coolant level, oil level, coolant temp, thermostat etc... Depending on if those 5 extra wires are information on motor vitals, we may need to begin to theorize how we're gonna get this done. I hope you dont have to go to the extreme of swapping the cars harness although it is doable...

Keeping my fingers crossed for you OP
