Where This Housing Fits in the Build
This is a wire-to-board interconnect housing. On the harness side, you crimp the matching KK254 crimp terminal (sold separately) onto 20–24 AWG wire, insert it into the housing cavity until the terminal lance locks, and then mate the housing to a through-hole or SMT KK254 header soldered to the PCB. The 9-position count matches a 9-circuit BOM line — confirm the header on the board has the same position count and pitch.
