Re: Disposal wiring too short
Disposals are not - should not be - hard wired. There should be a switched outlet under the sink. The disposal itself will have a short power cord that is then plugged into the switched outlet. If this cord is too short, then replace the cord on the disposal with a longer one Any appliance shop or hardware store will have replacement disposal cords.
As for changing the cord, all it takes is a screw driver. Remove the cover plate on the disposal, note the locations of the existing cord wires. Remove old cord and install new. Reinstall cover plate.
