P-Rails Wiring Help

I'm putting a pair of P-Rails into a Troublemaker Telecaster, with 4 push-pull pots to control the voice switching on each pickup independently. No, I don't want to use the Triple Shot pickup rings.

This is the control scheme I want to achieve for both pickups:
  • Volume pushed, tone pushed: P90
  • Volume pushed, tone pulled: Series
  • Volume pulled, tone pushed: Parallel
  • Volume pulled, tone pulled: Rail
I made this wiring diagram, and I hope it's correct, but I'm guessing it isn't.

I've wired things up with temporary alligator clips, but when testing the pickups by tapping them with a screwdriver, the P90 and Rails both make noise, regardless of whether the pots are pushed or pulled.

Thanks!

The most obvious thing I see in your diagram is that you can never get humbucker mode from either pickup...nowhere do you connect red to white.
 
When Vol and Tone are pushed you get Rail (not P-90)
When Vol is pushed and Tone is pulled you get parallel (not series)
When Vol is pulled and Tone is pushed you get nothing (not parallel...because red wire goes nowhere and black + white are shorted together).
When Vol is pulled and Tone is pulled you get P-90 (not Rail).

Where did you even get this diagram?! If I remember correctly there is a diagram on the SD website which works.
 
I made the diagram myself. Not surprised at all that it's incorrect. The goal was to get P90s on in the pushed/pushed positions, since that is what I want the default to be.

I did call Seymour Duncan support, and they said that it wasn't possible to achieve what I wanted, and that the humbucker tones had to be on the pushed/pushed and pulled/pulled settings.

Does anyone think there is a way to get it how I want it?

My diagram is a modification of this one I found in this thread.

Seymour Duncan don't have any diagrams showing bridge and neck pickups being controlled by separate sets of volume and tone pots.

I don't believe that's correct. Let me chew on this. But give me a day or two. (Probably tomorrow.) Been busy with doc appointments and life stuff.
 
The default setup from Seymour Duncan has the Series humbucker as the "default" pushed sound. I want, if possible, to have the P90 active when all the pots are pushed down.

Just reverse the way the tone p/p is wired (as if you just turn the picture upside down to wire that one).
