The Molex 3191 series 0019092047 is a 4-circuit single-row plug housing designed for wire-to-wire or wire-to-panel interconnect in power and signal harnesses. The housing accepts male or female crimp terminals (contacts not included — order separately), terminated to the wire before insertion. Panel mount snap-in feature lets the connector lock into a chassis cutout without hardware, which speeds assembly on a harness line and makes field replacement straightforward.
