Thank you lowpt! I hadn't even considered that, seeing as it seemed that it was my power outlets that were not working, and I thought that that was connected to this mystery fuse. It seems the 2 are not connected at all.
I looked through my 'accesories' that can plug into my lighter sockets, low and behold, it was my GPS charger that was missing the end! I didn't even notice.
Just put it back together, but now before I can test it out, I'll have to check the fusebox under the hood and hope that a blown fuse is why the outlets are not working. Very weird coincidence that those 2 things would occur at the same time. Oh well.
Thank you everyone else too!
