Engine stays running without key in ignition (and more!)

Kinda reminds me of when i was a kid and installed a Grant steering wheel, i made a right turn and the horn went on and wouldnt stop LOL! I had a friend in the car he was looking at me like WTF? I seem to recall pulling over yanking the battery cable then ripping the horn button off and disconnecting the wiresLOL!

Haha! I've heard of friends connecting their buddy's horn to the brake switch...I'd love to do that someday.
