Totally stumped and at end of patience on how to separate oxygen sensor electrical connectors. Have a clue how its supposed to work so maybe I have a bad/wrong technique. It cant be as difficult/imposssible as im finding it . WILL SOMEONE TELL ME THE PROCESS TO SEPARATE THESE THINGS so I can feel pretty stupid finding out how easy it should be I guess. Thanks. ( attached is not the 02 sensor connector but another easier to picture that looks like it)

 

Press the ribbed tab on the top left of that picture and pull the right side out of the left side.

 

thanks for trying but thats not the answer, If there was something to depress i would have known thats how but that ribbed part is part of the mold, not anything that depresses. I'm guessing something needs to be stuck in somewhere to a release point but have had no success with my guesses where

 

Actually it is the answer.
