1991 explorer brake problems

I have a 1991 ford explorer that is a base model. I recently noticed that I do not have any brake lights what so ever. I replaced the bulbs, still nothing. I replaced the fuse, still nothing. I then lowered the interior fuse box a little taking care not to pull any wires and noticed there was only one wire going in to the fuse for the tail lights, I traced the wire and it goes back in to the fuse box on the other end in to a bigger round fuse. I searched but couldnt find any other loose wires. I tore the dash apart and still couldnt find anything. My question is how do I wire my brake lights up? I am stumped. also the horn is the exact same way, but not too worried about that one. thanks in advance.

So the wire that is in the fuse panel for the brake lights (not just the tail lights, do they work by the way?), which wire is it? Is it the hot (supply) wire or the output to the brake pedal switch (red/white wire)? You want to be checking fuse 4 of the instrument panel fuse panel. It appears there may be a supply buss inside the fuse panel rather than discrete wires to each circuit. Is that maybe what you are seeing?

The stoplight switch feeds the high mount stop lamp in the rear directly and the tail light assemblies via the multifunction switch. Does the center high mount light function properly?

ok the wire that I see that is for the tailights is red and white and it goes to another point on the fuse box, to a round thing. (sorry not my area of expertise) but all of the other fuses have two wires and this one only has one. I dont know if they have ever functioned as I just recently got the truck. what I do know is that it has turn signals that work right independently but the the hazards dont work at all, the low beams that come on with headlights on work just no brake lights. also not sure if it matters but it has a trailer wiring harness that is pretty ghetto!

If it has a hack job of a trailer wiring harness, that could matter a lot. I've seen far too many trailer wiring jobs done with scotch lock connectors to tap into the factory wiring. These connector taps are only intended for interior use in dry locations. They are not water sealed and therefore allow all kinds of junk to penetrate the wire tap and cause the wires to corrode, eventually breaking or going so high in resistance that circuits stop working.

Sounds like you need to find yourself a multimeter (or at least a test light) and a wiring diagram for you truck and start tracing the braking system wires. You may be able to find a wiring diagram on the Autozone website under the Repair Information section.
