Hi Ozzie, under 'wiring pickups' section on possibly 2nd or 3rd page you will find my post on how to coil split the stock humbuckers.
Black is hot, bare & green already paired are ground, with red & white also paired being the bit you disconnect for coil splitting.
To wire up just in series best to heat shrink over the exposed ends of red & white.
On the pre amp blend pot you should be able to see the earth as a wire will be running from a lug to base of the pot. There will be another connection going back to master volume and that is the hot. With 2 pickups i believe hot wires go to centre lugs on opposing sides of the blend pot and same goes for grounds.
I have something on usb with me here at work and shall send by email.
Cheers, Waz
