Accidentally erased that email with diagram, but was a lot simpler than the one you sent me. It was almost the stock strat wiring ecxept:

1) The red from the mid pup goes to the 5 way switch AND continues the the first slot on the push pull. The green is grounded to a pot.

2) The greens from bridge and neck DO NOT go to ground pot, they go the the center slot on push pull.

3) The last slot on the push pull goes to ground.

Tell me if this makes any sense: With push pull up the flow will be on position 5: From the Bridge RED on 5 way to Bridge pup out to green bridge, to Push pull connecting to MID RED tru mid pup and to ground. This is series no sweat.

Here is the thing: on position 4: You get exactly the same but the mid pup also gets connected at the 5 way switch?

What will this do?

Tha way I see it on position 5 Bridge and Mid are already wired in series and when you go to position 4 it will try to add the mid in parallel.
