Hello. A question about your planned selections in positions 2 and 4. Is there a reason to pair the inside coil of one pickup with the outside coil of the other in both cases?
The reason I ask is because when you have two coils in parallel the distance between them can have a significant impact on the sound. So I think your 2 and 4 would sound quite similar. I think you would have much greater variation between 2 and 4 if you had one position with both inner coils and the other one with both outer coils. This is actually the set up used in a some PRS guitars.

To be honest I was just being logical, my main interest is to have position 3 with both full humbuckers, so when I have the individual volumes I can get really interested mixes of sound. the guitar I am doing this on is a strat so I figure I will try to add a coil split to positions 2 and 4. I just want position 2 and 4 to sound some what different. I am open to suggestions. Thanks
PS: I also saw a video of a guy that had all possible combinations with 2 humbuckers and these were the ones that sounded better.

And, assuming identical pickups, this configuration maintains hum-cancellation as well. With RF76's plan, one pickup would need to be rotated (easy enough to do) in order for positions 2 and 4 to hum-cancel.
But around here, we aim to please the player's desires. So I drew this up, taking the liberty of rotating one of the pickups 180°. I believe this fills the bill for robertfripp76 's wish list, but we'll need someone to verify that I haven't made some foolish error.
Wire colors coming from the pickups are SD colors, from there, I altered colors for contrast between wires. Grounding is shown to a star ground point, but the backs of pots could be used if desired, so long as all the grounds connect. And, I have omitted string/bridge ground and shield grounds for clarity.
Position 2 the neck is bypassing the volume for single
And position 4 the bridge is bypassing the volume single
UGH . No, you're reading it right. I think I can fix that by disconnecting the common lugs of Poles A and C and running both volume controls off the A and C commons to output. At work at the moment so redoing the diagram will need to await the evening or weekend.
It's only the blue wire that's a problem (although it would still work just with slightly funny volume controls in 2 and 4). The easiest fix would be if instead of the blue wire going to the common lugs of pole A, you have two wires one from B2 to the left lug of N vol and one from D4 to left lug of B vol. Then the coil-splitting happens before the volume.
