I did as Jgiacalo described. Chopped the cable off leaving about 1/2", stripped the insulation and twisted the wires together. I didn't bother covering them with tape, I just twisted the exposed wires into a little pigtail real tight to the cap. You can do the same for non-shorting plugs, but in that case it is important that the wires are NOT shorted, and that they be covered so they don't short.
