    M70 EML DK motor + MAF plug part numbers

    I was told this plug does not exist as single item but is part of the engine wire loom complete. Investigated and found them. Special thanks to the parts specialist of my dealer in Germany, he checked with BMW Munich and extra ordered 1 plug for me and sent me the pics. Part number of the plug which goes onto the EML throttling valve is position 21 8 POL. 12521714053.
    A bit confusing as there are engines mentioned which do not have a EML DK like the E32 740 with the M60 engine, E31 850 and E34 535 with EML are not mentioned at all, but look at the drawings.

    I have ordered some for stock now.

    I also have the plugs on stock for the MAF connector, that is a similar problem to find them in the ETK.
    Listed NOT under E32 and E31! But the M70 engine needs it http://produkte.bilder-speicher.de/0...263113047.html
    2 x 12521737668 MAF connector old number was 1718126 PLUG HOUSING 7-POL
    usually the inner ring breaks

    Additional info, in case you are confused which pin goes where for the DK (throttle valve EML) motor: X1618 and X1619
    x1618 --> 1619:
    1 - rt - ws - ge --> rt
    2 - sw - ws - ge --> sw
    3 - gn - ws - ge --> gn
    4 - nc --> nc
    5 - ws - ge --> ws
    6 - ge --> ge
    7 - sw --> sw
    8 - nc -> nc

    based on wiring diagrams for my 11/88 750 http://shark.armchair.mb.ca/~dave/BMW/e32/e32_89.pdf

    thanks so much for the info. Part numbers are great as I need to fix my broken plastic connectors.
    I swear, my cars are like a girlfriend.
    Sometimes its a rough ride, sometimes its smooth motorin'.
    Sometimes she doesnt like how i treat her and sometimes i dont like how she behaves.
    BUT at the end of the day, she loves it when I am inside her.
