Pinout for hub edge connector?

Does anyone have a pinout for the edge connector on the hub? (where the cooling bridge plugs in)

P1050279

Since the cooling bridges are unavailable, I figured I’d try to handle the wiring myself, and put in a cooling fan.

Any assistance would be most appreciated. Thanks!!!

Does the followup post (with the “BTB connector of the cooling bridge” diagrams) at The pi-top [3] Block Diagram have what you’re looking for?
