Re: Wiring diagram for dual humbuckers + standard 3/5 way switch
Here's what I think most are looking for:
The 3rd diagram is probably what most are looking for; gives you both pickups as humbuckers, both humbuckers together, and neck or bridge in single coil mode.
The problem I had with the logic was remembering that you can run the middle wire (typically red or red/white) as the hot wire to only use the 2nd half of the pickup vs/ sending the middle wire to ground to only use the 1st half of the pickup. Might have to put the pickups in "backwards" to have the single side of the bridge closest to bridge and vice-versa for the neck.
