Dash Lights come on with Brakes

I have a 1992 S10 with a 4 cyl. 2.5 l motor and 120K miles. It was an old meter reader truck with a light on top. The light has been removed. I am having light issues. I noticed the brake fuse was not even in the fuse panel so I put it in and now when I push the brakes the dash lights come on and also that noise that reminds you that you have left your lights on will also sound (if no key in ignition) So I removed the fuse, my brake lights work without this so, but my turn signals are messed up too. If I turn right all the lights blink like hazards. My hazards are ok, headlights ok, left turn signals ok. No back up lights though.
I think I have entered an electrical nightmare.
I thought the turn signal switch was bad so I replaced it but nothing changed.
