JP6 Parallel Wiring Help

I have a single push-pull pot which I want to use to engage my Neck humbucker in Series/Parallel (Bridge remains always in Series).

I’m a little confused with how I should go about wiring this up as it’s different from the standard DPDT 3-way toggle in other guitars.

Anyone has a wiring diagram for this or suggestions? Thanks in advance.

I’ve attached the stock JP6 wiring diagram from EBMM CS for reference.
