Go to the Seymour Duncan or Dimarzio site and look up the wiring for 2x volume, 1x pot.

You shouldn't need a diagram anyways, it's pretty straight forward.

Go to the forementioned sites or google Jackson RR diagram and you should get it. If you aren't comfy going in, you might want to take it to a tech.
