Wiring Diagram

What do you plan to do with the 3-way toggle? With only 1 pickup you've got nothing to select between.

For 1 pickup, 1 volume and 1 tone you could look at this - http://www.seymourduncan.com/support/wiring-diagrams/schematics.php?schematic=1hum_1vol_1tone

2 pickups, 1 vol, 1 tone and a 3 way?
Sounds like you could wire it like a Telecaster

Hahaha, I see that I missed that the OP has a two pickup guitar. I thought he had a 1 pickup and a 3 way switch. Depending on the type of 3 way switch you can use the diagram that Kent posted. You could also look through the Duncan wiring diagram library - http://www.seymourduncan.com/support/wiring-diagrams/

If you DID have a single pickup and a three way switch, there are several useful things you could do with it, like splitting a humbucker's coils and switching between parallel and series connections, or changing out different tone caps or cutting it out altogether.

I couldn't find a diagram anywhere with that configuration, using a toggle switch instead of the 3-way blade.

Anyhow, all you have to do is combine two diagrams. Extrapolate... I hate to say use common sense, because I know it can be difficult to transpose or whatever :shock: , but part of the diagram is as shown, and the other part goes with what pertains to a toggle switch. Also, I'd have to assume the the humbucker has only 2 leads, or the colors start to vary and get complicated on the 4-wire humbuckers & you have to solder and join two together. Then you use the other two wires.
