I can't believe I have to ask this, as I've been doing my own wiring for years. But I'm having trouble with this one.
I have 2 IBZ/USA F series pickups. Wiring code is the same as a regular 4 conductor DiMarzio. I have a 3 way switch. I would like the up position to be the neck humbucker full, the down position to be the bridge humbucker full, and the middle position to be the neck humbucker in parallel. Or if that can't be done, one coil from each pickup in humbucking mode.
What doesn't work:
Scenario 1-
Green-ground
Red from both pickups-hot's 1 and 3
White and black from both pickups tied to the middle position.
Of course they do what I want in positions 1 and 3, but the middle position has a nasty hum.
Scenario 2-
Green-ground
Red from both pickups-hot's 1 and 3
White and black from bridge humbucker tied together and taped off
And all of the following:
-White tied to position 2, black to nothing
-White tied to position 2, black to neck pickups red
-White tied to position 2, black to ground
-Black tied to position 2, white to nothing
-Black tied to position 2, white to neck pickups red
-Black tied to position 2, white to ground
Apparently what I'm trying is possible, as I've consulted some of Ibanez's old wiring diagrams that feature similar pickups.

http://www.ibanez.com/support/wiring/W97034.gif . Notice both diagrams use DiMarzios, and accomplish the same thing, but use a different wiring scheme.
I have NOT tried tying the black to ground and the green to hot, as this really doesn't make much sense and it's a pain to solder and desolder things from the pot.
