Brake lights go out car won't shift?

What is your question?

94 mustang 5.0 automatic. Brake light sometimes go out when that happens the car won't shift out of park unless we push the button real hard. Boyfriend has tapped wiring or something down by the brake pedal. They work sometimes. But what's causing this and how do I fix it? Not sure if this has anything to do with it but few weeks before this started the dashboard light went out and our flip up touch screen radio stopped flipping up but the radio and CD part still works. When that happened no fuse was blown.

What makes this problem better or worse?

Better when boyfriend tapped wires or something but tape is melting.

How long has your 1994 Ford Mustang had this problem?
