The Molex 0349861605 is the 16-circuit male blade plug housing from the MX150 34986 series, a sealed wire-to-wire interconnect family designed for under-hood automotive and industrial harness applications where moisture and vibration are routine.
The sealed feature means this housing is designed to accept silicone- or rubber-sealed terminals and a mating receptacle with a perimeter seal — the assembly is intended for IP-rated environments where water spray or pressure washdown is expected.
Terminal Fit and Mating Half
This plug housing accepts male blade crimp terminals from the MX150 terminal family — the specific terminal order code depends on wire gauge (typically 18-22 AWG for the MX150 system). The mating receptacle is the corresponding MX150 34986 series receptacle housing (female cavities), also 16-position, 2-row, with the same locking ramp interface. Stock both halves or neither — an orphan plug with no mated receptacle on the shelf is dead stock.
