Need a help with SD JB coil split wiring for HSS Strat with super switch

Need your help, guys. Just replaced the pot control on my HSS Strat, as I want to give my SD JB TB-4 pickup, split coil feature. I've used the wiring diagram from the SD web site (please, see the attachments) for this case. However, something went wrong, as after everything was done, I've got no response from the bridge pickup, when the switch is in the position 2 (so only the middle pickup is working). Split works as it should - pulling the pot.
I guess the problem should be in the wiring of my super switch, as the diagram is with regular 5-way switch. However, the problem might be different. Please, share your guesses about what went wrong. Thank you in advance for any help!

The diagram is good, so something must be wired wrong. Also, you, (or that diagram), made the split function more complicated than it needs to be. Just solder the red/white together, and then that to where it is now. You don't need the black "bottom" jumper on the P-P.

Edit: I see you used a Superswitch. We'd need to see how you wired it to figure out whats wrong. It's terminals are completely different than the switch in that diagram.

Hi. Thank you for your response. Yes, I've got the super switch unfortunately, as it's way harder to find a wire diagram for it.
Please, find the "scheme" how everything is wired now, in the attachments. As bad as it drawn it's still easier to see where the wires are going, compare to what I've tried to show, taking a pictures. Please, let me know if you need any clarifications.

BTW, I've tried more simplified method, subjected earlier, with removing top jumper from the push/pull pot and soldering red and white wires together to one of the middle pot legs. The result remains the same: split works, all the switch positions works, except the position 2, where only the middle pickup is active.
 
I've figured it out, so living the information in case someone will look for it in future.
All you need is to put the jumper from the throw to what the black humbucker wire was soldered - to the one next to it (3rd). Now everything os working as it should.
 
Sorry I didn't get back to you. The wife and I have both caught the same bug. Glad you got it figured out.
 
FWIW that original drawing doesn't look like a Duncan drawing - for anyone reading this thread in the future.. It should work fine, though not the typical way to handle a simple split, but you said you got it from the SD web site, which I tend to doubt looking at that. Also, for any humbucker other than a JB, not sure why they wouldn't use a 500k tone on the bridge, since it has it's own tone (the drawing doesn't spec a JB, so...).
