1998 E39 528i Engine electrical wiring sensor connectors.
Thank you very much for the link to the wiring schematics, and for the two pictures that you posted, I really appreciate your help! Can I ask where you found those two pictures?
I have another newbie, novice question. On the purge valve, what does X6120 and Y6120 stand for, is that the BMW connector number stamped on the sensor electrical wiring connector, and sensor? If so, BMW engineers are a lot smarter then I originally thought, for not making each connector unique, and only fitting the correct sensor.
