1-1703843-1 vs 1-1418448-1 – Which Do I Need?

1-1703843-1 is the female socket housing – this is the connector that plugs onto the sensor or actuator body. 1-1418448-1 is the male plug housing – this is the connector on the vehicle harness side. For most sensor replacement repairs, you need the female socket (1-1703843-1). For harness repair, you may need the male plug (1-1418448-1).

Frequently Asked Questions

Q: Are these connectors sold as a set?
A: Yes. This listing includes both the female socket (1-1703843-1) and male plug (1-1418448-1) with pre-installed 18 AWG wire – a complete mated pair.

Q: What is the current rating per pin?
A: The 1.5mm series is rated for up to 7.5A per pin – suitable for sensor signals and low-current actuators. For circuits above 7.5A, use the 2.8mm Metri-Pack 280 series (13A/pin) instead.

Q: What crimping tool is needed for 1.5mm terminals?
A: Use a ratchet crimper rated for 18 AWG (0.5 mm²) 1.5mm pitch terminals – such as the Engineer PA-09 or equivalent precision ratchet crimper.

Q: How do I maintain the IP68 seal after field assembly?
A: Ensure the rubber wire seals are correctly seated around the 18 AWG wire insulation before inserting terminals. Using undersized wire (20 AWG or smaller) will prevent the seal from compressing correctly, compromising the IP68 rating.
