Brake lights do not turn off even when the key is out?

My brake lights won't turn off, while driving, I was told that the lights look like if I have the foot on the brake all the time, I have signals and reverse, they are working normal, I disconnect everything that is not part of the original set up hoping that maybe that would let me know if something that I put on is making a short but they still on, I change the brake switch, the one above the brake pedal, but still having the problem. Could the PCM be the problem?

Any guidance is much appreciated.
