Forget black/ white being the north coil red/green the south.
Black/white is the ALWAYS for the P-90s. In the bridge pickup the P-90 is the SOUTH coil. In the neck the P-90 is the NORTH coil. That makes one P-90 humcanceling with /the other one I guess.
It follows that the red/white pair are always for the rails, North in the bridge, South in the neck.
Simplest, right?
