40 amp fuse???

.....I was totally mistaken. I guess I should have taken a flashlight to this before...the housing at first glance looked very similar to the one for the 40 amps.
Actually, it's not for a fuse at all. It's a female connector for something???? I don't know what it is though. It looks more like a port??? It's right next to the 40 amp fuse so, if one of you guys could check it out quickly on one of your cars you'll see what I mean.

Sorry, my pictures are too dark to post.
