I have a 99 civic ex ... can somebody please tell me how to remove the oil pressure switch so that I can install the brass T-fitting? ... I see the gromet on it and the wire coming out ... just how do you remove the wire? ... i dont want to break it... thanks.

 

just pull the rubber grommet and wire off of the switch. then use something around the size of a 15/16'' socket to get the oil pressure switch off.
