  1. Pull the shifting cable, leaving the housing in place
  2. Slide new wire through the shifter and then through the old housing

  4. Slide the new housing over the new wire
  5. Cut wire and housing to desired length. At the derailleur end, you will want to withdraw the wire a bit (=extra wire is coming out of the shifter) so you can cut the housing without cutting the wire.
