Guitar Wiring Help

[spoontex]

I want to change the wiring of my Strat. Someone helped me to draw the schematic, but it's very difficult to me interpret it.

Megaswitch S
Seymour Duncan STK-S7  neck and middle
Seymour Duncan 59/Custom Hybrid bridge

I want to add a rotary switch to split the humbucker between: North Split, Full Humbucker, South Split.

Anyone can help me?
