This may seem like a stupid question but, did you check your brake fluid level? I had the brake light come on my wife's car and fluid level was low. Also, how are the brakes? I know you said the pedal felt ok. Pearl02.

Start by disconnecting your brake switch an see if the light goes out. Some vehicles have two brake switches, I dunno about stangs, if there's two disconnect both. If they're still on, disconnect the turn signal switch, should be a connector at the base of the column. If they go out, you've got a short in the column or turn signal switch. If they're still on, then start at the trunk lid and check the wiring. Trunk lamp wiring could be shorting to the high mount brake light. Maybe at the hinge, where the harness flexes. Work your way foreward. If youve got a water leak, at the sill plates or kick panels the wiring inside the harness could be corroded bad enough to cause a short. Good luck.
Make sure all the bulbs in the back are right. I've seen some stupid problems when people install the wrong bulbs.

What about a stuck relay in the main power block under the hood? Try removing the one for the brake lamps/fog lamps, or switch it with an identical relay to see if the problem shifts with the relay swap.
