crazy things happening here

hey guys, just curious if anyone has had or heard of an issue like this. my 71 chevelle will fire right up and drive fine but when i go to turn it off it will stay running. also when i push the brake pedal the fron turn signals light up like brake lights that is all i have noticed it does. i know it is a crossed wire or something along those lines but i wondered if it could be something in my steering column. any help or advice will be appreciated
