slant 6 ignition problem !!

so when i have the gauge cluster a little out (not touching any metal) i can put my positive cable on the battery. and when i do so the light where it reads 60mph is on. wich means that my high beams are on but i dont have the light switch on. and that light should only be on when i have my light switch on and the high beams.. right? electrical is such a pain in the asss!! but i feel im getting closer and closer.someone know whats going on there?
