DiMarzio's web site can help you out with that switching configuration as far as wire colors go if you have a standard 3 way like the one Ibanez uses. *
HOWEVER, I bought a 3-way switch from StewMac, and it didnt have a normal wiring pattern. *
To be polite, I wont mention who helped me out, because I dont want to volunteer someone else for help, but I'm sure this person might pipe up and help you out with your dilemma with a simple
wiring diagram for that StewMac 3-way.
