How do I disconnect a garbage disposal from a junction box? What to do with loose wires?
It seems like you know most steps leading up to it. Based on that it seems you only want to know what to do with the wires once disposal wiring is removed.

I would simply take wiring caps and place one on each exposed wire and then wrap each wire with some electrical tape further ensuring the caps stay on and do not become exposed if touched or caught when working around the wires. If you are keeping the junction box I would still use the same method but place wires back in the box and and screw the plate back on. Pull wire to sit inside of junction box or just place the end in the box and screw plate back on.


Screw on one wire cap/nut on each wire.

Tape each wire cap/nut separately
