The Contacts Are the Real Story Here
The single most important thing to know about the 104257-2 is that it does not include contacts. The housing accepts AMPMODU MTE female socket crimp terminals — you need to order those as a separate line item on your BOM. The crimp termination means you terminate the wire first, then insert the contact into the housing, which is standard practice for serviceable harnesses where individual wires may need replacement. The 3-position count and single-row layout keep this housing compact for low-circuit-count applications like sensor connectors or small power taps.
Latch Lock vs. Friction Fit
The single-row 3-position layout means the latch is on the short side of the housing, which is typical for this series.
