How do you get old wiring out?

To remove old wiring, first ensure the power is turned off at the circuit breaker to prevent any electrical hazards. Use a screwdriver to loosen any screws securing the outlet or fixture, then carefully pull it out to access the wiring. Disconnect the wires by unscrewing the wire nuts or loosening terminal screws. Finally, remove any clamps or staples holding the wire in place before pulling the old wiring out of the wall.
