Neopixel Switch help

So I'm trying to figure out the wiring exactly for between a pixel switch and a Smugglers Outpost 16 pin, 7 pole chassis connector.

I understand everything and would probably use AUX for the data in on the switch, but the pixelswitch has a data out pad and I am unsure what to do with it. Is it even needed considering some of the same switches use to not even have a DO?

Was trying to see if I could find a sub pcb for extra data in and out, but wasn't having and luck, considering the blade and NPXL hilt have LED's themselves that would require data pads themselves for Data 1 and Data 2. Is there other chassis connectors that have more data perhaps?
