just a dumb question

Probably for an accessory that you do not have. I too made the mistake of looking behind the dash and finding one of those errant plugs, spent hours looking for the female end. This happend late at night so I did not have the opportunity of calling Ford. The next day when I did I was told that it is most likely for a light or guage that I do not have in the vehicle. I was also informed that the wiring harness is made for other vehicles as well, Maybe I have all the bells and whistles but I may not have the same thing as say a Eddie Baur (SP). If all is working as it did before then I would say you found a dead end plug. If however something is amiss, then you know what you must do!

i just wanted to say thank you for you reply i know it is for something i dont have i was just curious as to what it is for i have seen dead end plugs in my car before but this one is pluged into a spot that was specifically meant to hold this dead end plug they are usually just left hanging around with nothing to hold them got me puzzled thats all

Most likely just for anti rattle purposes.

If your concerned like I was I'd just call Ford and ask them
