what is the part number of the header that the AFPG804 plugs into?
The connector doesn’t appear to be specified, since the part is sold as a replacement assembly at a rather substantial markup…
However, it seems to look an awful look an awful lot like a molex picoblade (e.g. WM1720-ND) housing. Please verify, but if it looks like a match the corresponding headers and contacts should appear as mating and associated product respectively near the bottom of the linked page.
