    I think you need to ellaborate a bit... are you having a coil problem with your M10 and going to put an M20 in instead?

    I'm not sure about the wiring thing... Bentley should have that figured out but I don't have that book with me at the moment.

      I HAVE AN 84 318I AND I PUT A MOTOR OUT OF A 90 325I THAT I HAD WRECKED, I AM NOT GETTING SPARK FORM THE COIL OR AN INJECTOR PLUSE. I THINKS ITS IN THE WIRING, NOT HAVING A GROUND OR MISSING AN HOT WIRE SOMEWHERE DOWN THE LINE.

        I had pretty much the exact same problem when I went from an ETA to the "i" engine. No fuel, no spark.

        It was eventually diagnosed to be a problem with the OBC "disable" option. My car didn't originally have the 13 button OBC, so I swapped it in with the new engine. I was missing part of it, and this pretty much told the ECU that I was trying to "steal" the car, and it shut off the fuel and spark.

        Have a look into this, hope it helps.
