A Nippon Denso (1 x SET) connection typically refers to a complete kit containing both the male and female 2-pin connectors, along with the necessary terminals and seals for a full, waterproof
Set Components
A single set (male and female) is designed to allow a complete, weatherproof connection to be built or replaced. It typically includes:
1 x Male connector housing and insert. This end often goes on the engine harness side or can be wired for an adapter.
1 x Female connector housing and insert. This end typically connects directly to the fuel injector or sensor.
2 x Male terminals.
2 x Female terminals.
4 x Silicone rubber cable seals (rubber bungs) for waterproofing the wire entry points.
Optional Pre-wired Cable: Some "pigtail" sets may come with a short length (e.g., 20cm) of wire already attached to the terminals, simplifying installation.
Key Specifications
Pin Count: Most commonly a 2-pin connector, although variations with more pins exist for alternators or other systems.
Compatibility: Widely compatible with Nippon Denso and Sumitomo-style fuel injectors used across brands like Toyota, Honda, Nissan, Mazda, and Subaru.
Interchange Part Numbers: Common cross-references include Toyota 90980-11153 (female side) and 90980-11875 (male side), or Sumitomo 6189-0060.
Keying: Available in "Top Slot" (high keyway) and "Dual Slot" designs to ensure correct mating and prevent misconnection.
Typical Applications
Fuel Injectors: The primary application for these sets, especially when replacing old, cracked plastic connectors that can cause misfires.
Sensors: Used for oil pressure, temperature, and pressure sensors.
General Automotive Wiring: Their waterproof design makes them suitable for general electrical accessories, fuel pumps, and various switches in harsh environments.
