Refuses to discon:(inverter cable, rear grey cylindrical) B+ connector

I'm out here looking at a generation to an '05 I believe this is where the whole front of the car is off and I cannot see a plus b terminal like you have at all I see the openings and I have a great plug and a black plug that go into these other plugs in a hole that a 10 mm bolt holes in but for the life of me I don't see that single plus b mounted anywhere and I'm standing right here kneeling down looking That's really strange

 

You want to slide the plus b big white terminal gray housing off of the gold bracket Is that what we're trying to do

 

Yes it does not want to come off of that gold bracket even with that little tab pried all the way up so it looks like I would just undo the gold Phillips screw that holds the bracket down and then spray some WD-40 or croyle on it and see if you can slip it apart that way It may not be long enough coming out of this side cover that the white wire that goes into that plug is coming out of it may not be room to do that

 

Did this work Is there enough of the white wire inside under the plate that will literally just pull out so this connector can come loose or does the gold Phillips screw need to come undone on the bracket or is it glued under the plate that holds the mess down on the inverter That's a chore in itself just to get that a little bit off inverter It is glued down
