Does your new switch have a knob on it? Because the black plastic knobs are molded on to the ends switches and cables, you have to cut them off. I used a razor knife and a pair of needle nose locking channel locks.
it'll pull off, so will the cable ends if you pull em hard enough, i know i had to glue all of mine back on. you can also buy replacement knobs in the factory style, or machined billet aluminum they are pretty nice.
