I know that this is a tired subject, but I have to find out how to disconnect the grey clip from the engine coolant temperature sensor. I can find it and unscrew it, but I cannot figure out how to unclip it. I do not want to replace this factory harness piece, so I don't want to pull at it w/some pliers until it breaks. Sorry for the tired subject, but the thread that the search brought up had no details on how to disconnect this clip. Thank you.

 

Push in the release tab and pull

 

Sometimes it helps to just walk away and clear your head for an hour or so. The clip should slide off with a little bit of encouragement. You can pull prety hard w/o ripping the wires apart so go get a screwdriver to help you pres the tab in on that little plastic clampie thingy and get er dun
