22-position Mod IV receptacle housing — what you're working with
It's the wire-side half of a crimp-to-wire interconnect — you terminate individual contacts onto wires, insert them into this housing, then mate it with a matching header on the board. It sits in the harness, not on the board. Crimp termination means you choose the wire gauge and contact separately.
Contacts are ordered separately — that's the main gotcha
The listing states Contacts Not Included.
