Not turning off??
 

My 95 ford bronco turns on and runs great, However when I turn the key to the off position my bronco won't turn off. The key just loosly turns. I had replaced the lock cylinder and is still doing the same thing. What else might be the problem?

The ignition switch.Or the actuating rod

might be the solenoid too. check them connections.

Where is that located?

If you're referring to either the solenoid in the fender or the one in the starter, neither will cause this. Those could cause the starter to remain engaged, and you would notice right away.

im talking about the ignition wire that runs to it
