The TE Connectivity 174952-1 is a 20-position, dual-row plug housing from the Multi-Lock series, designed for wire-to-wire or wire-to-board power and signal interconnects in automotive, industrial, and appliance harnesses. This housing does not include contacts — the female socket terminals are ordered separately and crimped onto the wire before insertion.
Wiring This Housing: What You Need Alongside It
Because the 174952-1 ships as an empty shell, you need the matching female socket crimp terminals — TE's own Multi-Lock contacts — to populate the 20 cavities. The dual-row layout with 5.90 mm row spacing gives good wire routing clearance in a sealed or unsealed harness.
