Need help designing a particular mustang scheme

It's my first build and it's going to be a three pups mustang. There are two possible configurations: SSS (single coil neck, P90 middle, and single coil bridge), or HSH (with both humbuckers coil tapped).
It will have 1 tone and 1 volume knob just like a normal mustang. With the SSS config, i'll go for a three on/off jag switch like on the Cyclone 2 to turn on and of the pickups individually. With the HSH i'll have to keep all that stuff and drop in two classic Mustang three-way switches with "single coil/humbucker/out of phase humbucker" function.
Can you guys tell me how to draw the schemes for this and actually wire this?
Any help is gladly appreciated

I can draw you a diagram for whatever you want, but what you've described will not be possible.

In order to do single coil/series/series out-of-phase switching, you will need a switch with three poles and three throws. To my knowledge, no one makes a 3P3T mini toggle, and rotary switches commonly have 4 or more positions.

Personally, I would skip all phase inversion switching, or possibly just have one phase switch to put two pickups out of phase. Phase inversion is usually not useful unless you want to make awful noises, since it causes destructive interference of the output waveforms of most of what any two pickups or coils transduce.
Series/single coil/parallel switching, by contrast, is arguably more useful for most humbuckers, and can be done with a simple SP3T/DPDT On-On-On mini toggle.
 
Mustangs have three-way toggle switches (three way means three throws i guess, don't know really). I have no idea how switches work though, if you say it's just not possible, i'll believe you.
This  is from wikipedia, if you can make any use out of it: "The Mustang is unusual in having neither a pickup selector nor a circuit selector switch, instead just using the two pickup switches to allow the pickups to be used either singly or in parallel. The second on position reverses the phase of the selected pickup, allowing the pickups to be either in or out of phase when in parallel. This phasing option was also unusual for 1964.

It also meant that, as both pickups were floating with respect to ground, it was possible to modify the wiring to put the pickups into series either in or out of phase without excessive noise. The unusual switching could also be replaced by a conventional pickup change switch using the unused body routing already provided for compatibility with the Duo-Sonic, requiring only modification of the pickguard, and freeing the two eight-terminal pickup switches for other uses. As with many student guitars, aftermarket pickup additions and changes are commonly found in many vintage examples."
What is parallel/serial wiring? How does it affect the sound?
I need a split coil switch, and i thought to exploit the mustang  three-way switches since it's going to be something like a mustang, i don't care very much about the third way, if i can get some more versatility out of it that would be cool, no matter what the function actually is.
I'm going to play blues and rock with it. I guess making awful noises doesn't get along with it  :icon_biggrin:

A 3P3T switch would have twelve terminals.

FWIW, that information looks incorrect. The pickups do not float above the ground potential on many instruments. Without the use of some differential preamp, or a balanced output which does not utilize the ground, at least one pickup coil must be grounded at any given time.  (The Mustangs are clearly passive, and the output is unbalanced.) Theoretically it is possible to change the potential seen by a pickup by placing a resistive load between it and ground, but this serves no functional purpose. 
 
Oh i see. I wonder who corrects wikipedia's pages though  :)
Allright, then. Could you draw me a dagram with the specs i said before?
And instead of the out of phase function, the parallel function.
One last thing: if i'll end up building an SSS, would the diagram work the same just by taking out the split/parallel switch?
If you need some other info, i spoke about the project here http://www.unofficialwarmoth.com/index.php?topic=18824.0 and here

Thank you sir
 
This works for three singles:

Add this for humbucker splitting:

Thanks man.
No problem understanding the single coil one.
No idea about the other one lol
Aren't the pups supposed to have 2 wires? One for ground, the other like you draw, right?
Thanks for the help, really.
