Listen to the wife (just this once!). On removeing the brass terminals, the male ones, one leg is unsupported & it can be hard to see which one it is when they are installed in the bulkhead (tho comparing shapes of the new to old might ans that, not sure), so press on both legs & the one that gives, move it in a bit till you can easily pull the wire/terminal out of the back side of the bulkhead, no need to force it, when it is moved sideways in the right amt it will slide back out fairly easy. On the female ones, look at the bulkhead front cavity & on one long side of the bulkhead rectangle there will be a little hole & stick an eyeglass mini screwdriver in there & depress/flatten out the "tab" that you see in the pics of it (press the screwdriver sideways as opposed to leverageing it at an angle which can crack the bulkhead plastic) & same thing when the terminal is flattened flush it will pull out the back side pretty easy. when reinstalling the new female one, first lift up the tab a bit from flush so when installing & you pull the terminal/wire backwards into the bulkhead you will hear the "snap" when it locks into place. some paste for increased conductiveity might be a good idea, not sure what to recommend.
