Sealed 4-Position Plug Housing for MX150 Harnesses
The housing is sealed — rated for exposure to moisture, dust, and underhood splash — and the black glass-filled SPS insulation handles underhood temperatures.
Mating Connector and Terminal Selection
The 0334814401 mates with the MX150 33472 series receptacle housing (same 3.50 mm pitch, 4 circuits). For the crimp terminals, use the Molex 33000-series male blade terminals — these are the MX150 standard contacts for 18-22 AWG wire. The housing accepts the terminals after crimping and the secondary lock (TPA) on the receptacle side confirms full seat. Pin 1 is marked on the housing for orientation.
Sealed Duty and Locking Ramp Retention
The sealed housing means this plug is suited for engine compartments, off-road equipment, marine electronics, and outdoor machinery where water ingress would kill an unsealed connector. The locking ramp engages with a positive click — it won't back out under vibration but can be released with a tool for service. The free-hanging mount lets it float in the harness rather than being panel-fixed, which helps with routing in tight engine bays.
