The actual socket itself is probably part number 6W7Z-15055-A but I don't know what year you have, and where this is located. Also some are lit (have a glowing ring around them) and others don't, so that might make a difference (and how they are wired up).
Also be aware that this same socket is used in many Fords. It seems to be the same one from my 2000 Grand Marquis, and I pulled one from something else to replace it. I probably have at least 10 of them in my parts pile, most still in the cup holder/ash trays. If you have a you pull it junk yard, they are usually a couple of bucks.
The part that might change, and the part that might be broken, is the retainer, and there are a few variations on it. Like 1L2Z-15K040-AA I like to practice removing stuff like that on vehicles in the junk yard so if I break it, it wasn't mine, and hope the next one doesn't break. I think I have a youtube video of taking them apart, but I can't seem to find it.
