    Distributor Cap - Spark Plug Wire rotation - 1981 745i

    Hi, does anyone know what correct order the spark plug wires go on the distributor cap? I cannot find the notch on the dist cap lip. I know it goes clockwise.

    This is for a 1981 745i. Thanks in advance.

    Uh, it is on the valve cover... 1/5/3/6/2/4

    That diagram is wrong.

    Ha! Hit Man X you’re so right! I didn’t even look at the sequence. I thought it was helpful showing where cylinder one is on the cap(the rotor pointing at cylinder one TDC). That was the First picture when I googled M30 firing order sorry for any frustrations.
