For "normal" sound, the bridge pickup should be in phase with the neck pickup. For your model of pickups, it means that for the bridge pickup, the red and white leads are connected together, the green lead goes to ground, and the black one is the hot. It's the same for the neck pickup except that you have to reverse the black and the green wires. (Physically reversing your pickup requires reversing the wiring to maintain the phase relationship between the two pickups.)
Since they are both humbuckers in themselves, they will be humbucking whether one pickups is connected in phase or out of phase with the other. Connecting them out of phase would make the sound "thin and nasal" in the words of the SD website.
