Anyone have wire diagrams for the 1990 F150. I have a few problems and Haynes and Chilton's don't show much outside of engine wiring.
Thanks

 

what kind are you looking for?

 

Chassis, Cig lighter, Horn. i have a problem with circuit. Fuse is 30 amp so i presume other items on are circuit. Fuse blows with engine on and horn used. With engine off either key on/off horn works fine (new fuse). Only with engine running.

 

see if this works for you http://www.autozone.com/autozone/rep...96b43f8038ecd6
