brake light switch

When i let off of my gas pedal, my abs light comes on, and my head unit turns off. What could be causing the problem, i have already checked the fuses both under my steering wheel, and under my hood. I'm not sure what else it could be.

Ive got the shift lock issue, did the search and started the trouble shooting and noticed something I haven't read about. While pushing the brake pedal in I noticed I had no brake lights, checked fuse and good. Tried again then had lights, noticed its like I have to push pedal in and out before...
