Yep, as per above, I'm assuming the switch works like this:


Across the 5 positions:
1+6 -> 7
1+2+5+6 -> 7
2+5 -> 7
2+3+4+5 -> 7
3+4 -> 7

If it does, then this should work for your wiring:

If your pickups are a mix of different manufacturers then there's a chance you could have some phase issues, and/or not get hum-cancelling combinations when the bridge is split. But, that can usually be solved by swapping the way the humbucker is connected or its coil ordering.

Good onya WeirdBits, that's actually very similar to my solution, some Humbuckers use a green wire as the main signal-out wire and use the black wire as the ground wire and then the red and white wires are soldered-together.
