Welcome to Stangnet.
I moved your thread into the '96-04' section and edited your title . This way more members will see your thread,and drop in with ideas/advice.

When you say you have power everywhere-does that include at the brake light switch? Also have you checked the ground wires?
 
i had that happen once with an 03 but mine wouldnt come out of park either, i had kicked some of the wires under the dash and the ones for the brake switch came loose

The grounds were showing good I have power in and out of the brake light switch.
 
CONFIRM +12 volts at the high mounted 3rd brake light using a KNOWN good ground.

IF no voltage at the 3rd brake light but confirmed voltage at the brake pedal switch the problem MUST be a wiring fault between the two locations.

Before chasing a wiring fault I strongly urge you to double check your work or a wild goose chase could be in your future.

Start in the drivers side kick panel. There are a lot of connectors in there that run from the front harness to the rear of the car. I've seen them get dirty, broken or pinched over the years and cause odd problems.
