Does anyone have any clue how to remove this orange connector!? I've been fiddling with it for some time and it won't budge. There doesn't seem to be any tab to press like on the other ones. Maybe it was already broken off? I'm at my wits end.

 

There should be a tab in the middle of the connector there. It looks like it may be depressed in your photo. It also looks like it's already partially out

The right hand side of the connector from your perspective looks like it may be damaged from prying.

Double check for the tab in the middle. You might be able to get it out by prying in between the connector and the housing by alternating with a flat head screwdriver on each side of the connector.
