The 2036320401: It is a free-hanging (in-line) connector body that accepts male pin crimp terminals — the contacts are not included and must be ordered separately.
The 4 positions in a dual-row arrangement means two circuits per row; the mating header must match this exact 4-circuit count. The locking ramp is the primary retention feature — it clicks into place on the header latch and holds against cable pull and vibration, a real advantage over a friction-only fit in a field-service or mobile application.
Mating and Termination
This housing mates with any Micro-Fit 3.0 header of the same 4-circuit, dual-row, 3.00 mm pitch configuration — typically a vertical or right-angle through-hole header. Termination is crimp-style: the installer selects the correct male pin terminal (Molex Micro-Fit 3.0 crimp terminal, sold separately), crimps it onto the wire, and inserts it into the housing cavity until the terminal latch seats. No contacts are included in this housing — the BOM must list the terminals as a separate line item.
