Welcome to Guitar Tricks, Laurathecoconut!

Look for the wiring instructions at the DiMarzio website.

They use different colour coding for the wires, but you should able to figure it out.

BTW: I strongly recommend using series/parallel switching for the humbuckers instead of a simple coil tap. Coil tapping simply shorts out one of the humbucker coils, and then you lose the noise reduction a humbucker (hum bucking) is designed to provide.
