May not help, as I could not see the 4 pin connector. Page 69, 70 have different plug connections and is not what you are looking for. Sorry, I am not a Tim Taylor.
"The plug connector concept is identical to the MEVD 17.2 in the N55engine. There is a logical division into six modules." hence some similarities to the N55.
Is this motor not the same as the E70. I guess there are not RChips You Tube videos for the E70 v8?
Nice that you are sharing with us. Funny RChip says the install takes 15 mins. RChips really should be more clear with the instructions and should know what exact pin connection is on the F15 rather than asking you, sounds like BMW sometimes.
