Interrior neon lights

hi i recently had purchased sum cheap neon lights like that you would plug into ur cigarette lighter.. i cut off the cigarette lighter and wondered if anyone knows where or how i can hook this into my fuse box so it gets power and the lights turn on when i start my truck.
i own a 91 chevy s-10 lowrider.

you can run the positive to the fuse that goes to the headlights, and run the ground to any bolt on the body!!

thanks i will have to try that and yes i was also wondering my lights in my dashboard are not working and i checked and changed all fuses but cant seem to find out whats wrong with it.
