A person I hired to change the key switch shorted a wire out on the harness it is a little black wire with a white stripe on it. It goes to the key switch, but I need to know where it runs to.

Hello, if this is the correct wire, it appears to be one of the ground wires for the body control module and warning system, you'll see in the diagram it grounds the Headlamp switch as well as the door lock switch. Did he short this wire to a power wire? Or is there a blown fuse?

Added one more diagram showing the Ignition Key Alarm Switch, so this would be the dinging sound when you put your key into the ignition switch.
