1993 Corolla brake light fuse issue

Newbie here. I have a 1993 Corolla that began blowing brake light fuses a couple of months ago when trying to shift out of park. I started replacing parts to try to locate the cause. To date I have replaced the brake light switch, the shift lock solenoid, the computer by the solenoid, the tail lights & tail light harnesses. The fuses keep blowing when I try to place the car into gear. Is there anything I could be overlooking that is causing the fuses to blow?
Any help or suggestions would be greatly appreciated!
