Depends a bit on what you want it to do. Simpelest would be to use standard strat wiring. Since it has a humbucker at the bridge you could add a switch to tap it. That would add a more standard strat sound.
I have thought about putting an "always on" switch for the neck pup to get more of a tele sound or use all three pups at once.
Do you know it the middle pup is reverse wound? That could also make a difference.
