Have replaced pin and plugs to injectors--Have crimped and soldered them-- Got a good solid fit to the injectors--------Coming off the same harness at the front of the engine are a series of two pin sensors--One goes to the air intake blue and brown ---To the right and just behind a large two pin(no problems)--- To the right brown and green--And to the right brown and black--these three sensors have plug 004 545 48 28 on them ---QUESTION ARE THESE 3 SENSORS +&- SENSETIVE IF SO WHICH COLOR GOES TO THE LEFT PIN--I WOULD ALSO BE INTERESTED IN KNOWING WHAT THESE SENSORS ARE AND WHAT THEY DO--Thanks for all help

Two wire plugs are for the most part not polarity sensitive, the ones that are have 1 or 3 or more pins.
