Re: Neck, Series, Bridge Wiring
It's actually much simpler than that, and Minions has it right. You connect the pickups in series then treat it like splitting a humbucker - select a coil by shorting the series link to either hot or ground.
You'll need a SPDT(or half a DPDT) ON-OFF-ON, or you could use a DPDT ON-ON-ON by using the lugs that do not connect in the middle position. If you want to use a Gibson-style toggle, you'll need the right-angle DPDT version.
