    Can anyone help me know what harness pin is crank position?

    Getting frustrated. Cant find a pinout of the m50 vanos harness and I want to trace my crank sensor to make sure things werent plugged in backwards by previois owner.

    Ive tried the ETM but I cant find it... maybe im just frustrated and blinded by seeing red.

    Someone please help

    On a M50 tu the crank signal wire is a yellow wire pin 16 on the DME. Crank position ground is a black wire pin 43 on the DME. On the sensor pin 1 is signal pin 2 is ground.

      Thank you!

      Dme pins counted right to left?

          You the man!

          Hoping PO just plugged sensors backwards. Crank sensor ohm'd to 540 so it should be good
