Thanks for the donation, does the high-mount brake lite work? Are you three door or four door?

Also, at the central junction block, under left side of dash, fuse 54-- 15 amp, use a teslite, see if fuse circuit is hot, should be hot all the time.

Under hood fuse box, driver side rear, fuse 1--40 amp, check the fuse and see if the circuit is hot, key on.

The wiring diagram for the brake lites showed fuse 54, hot all the time, but, looking at the power distribution diagram, to track the circuit to fuse 54, shows the the key has to be on, for the feed to fuse 1 and fuse 54 to go hot. Turn the key on to check fuse circuits for voltage. Sorry for any misinformation, I can only go by what the wiring diagram shows.

I'd have to get at the wiring circuits to the fuse box, under left side of dash. As you can see, green wire with red tracer carries voltage to several fuses, including fuse 54. The info I looked at was for Focus LX.

Did you check for voltage to and from the brake switch? Dark green wire with white tracer is voltage to the brake switch. Green wire with red tracer is voltage from the stop lamp switch, for stop lamps. If you have IVD, there is a stop lamp relay, under hood passenger side rear, you'd have to check relay circuits, replacing relay may not help anything. If you have that relay, coil side of relay is controlled by electronic stability module. I can't troubleshoot that module from here, I'd have to look at it.
