On a 93 Explorer, there are 2 options. Being a 93 Ford, it might be the same. There are no Guarantees.
If the truck has speed control, then there is a horn relay. It looks like it is under the dash near the steering column.
If it dosen't have speed control, it is only the switch in the steering column.
In my explorer book, it goes from fuse #8 to either the relay or switch, and then to the horns.
Try to run a jumper from the hot (+) terminal of the battery to the horn to make sure the horn actually works.
Just realized one more thing.
Check the fuse box under the hood. In my explorer, the power for the horn and several other devices routes first through the power distribution box under the hood.
