- I need the layout of the fuse box for my 1981 F-150 4x4. My lighter and horn quit working at the same time leading me to think it is a fuse but I don't know which fuse is for which system. Anybody have a diagram they can download for me?

 

Its on the cover, i'll guess yours is missing. Ill take a picture and report back!

 

Sorry its not too clear, but i cirlced the cigar one. PM me with a email address and ill get you a better pic, because its not showing it as large as it should for some reason.

 

 

Oh wow, i didn't think there was a difrence between the 80-86 range. Mines from a 86, so disregard it!

 

Thanks all! Ryan's photo helped narrow down to the right fuse and I got it changed out. I've just relocated from Southern California to the Portland Oregon area and all my manuals are boxed up in storage otherwise I would have just looked it up myself.
