Tug on the wires going into the pipe while watching the other end. If you can
pull them out attach a stout cord to the far end and pull the wire out. Add a
red wire to the pack and pull them back. Then hook them back up matching the
colors and using the red/black for the hots. Look in the panel and verify the
white is connected to the neutral bar. Then you will be OK for your 120v
outlet.
