Disconnecting electrical connectors can be frustrating. Some connectors have squeeze tabs. Some have tabs to lift. Some times, on some connector, I have lifted the tab(s) with one screwdriver (or, two for two tabs) and used another screwdriver to encourage the halves to part.  
Your repair manual may have a picture to show you how. Does it?
