7-Pin 3.0mm Series Unsealed Female Motorcycle Connector – Cable Plug for Wiring Harness
A direct OEM-specification 7-way female connector in the 3.0mm pitch series, designed for motorcycle, ATV, and scooter wiring harness applications. The 3.0mm pitch accommodates heavier gauge wiring for higher-current circuits such as lighting, ignition, and charging systems.

The 3.0mm pitch series is the standard for higher-current motorcycle circuits where 1.5mm or 2.0mm pitch terminals would be undersized. Common applications include main wiring harness junctions, lighting relay circuits, and charging system connectors where wire gauges of 1.25mm² to 2.0mm² are required. The larger terminal cavity provides superior crimp retention and lower contact resistance under sustained load.
1 × 7-Way Female Connector Housing (3.0mm pitch) with wire leads and terminal inserts pre-installed.
Q: What is the mating male connector for this 7-pin 3.0mm female?
A: The mating male housing uses the same 3.0mm pitch series. Common OEM cross-references include Sumitomo MT series and Yazaki 7283 series 7-pin male housings. Verify pin layout against your wiring diagram before ordering.
Q: What wire gauge does the 3.0mm terminal accept?
A: The 3.0mm series terminal accepts 0.5mm² to 2.0mm² (20–14 AWG) wire. Use a ratchet crimping tool with the correct 3.0mm die for proper crimp height and terminal retention force.
Q: Is this connector compatible with Honda, Yamaha, and Kawasaki motorcycles?
A: The 3.0mm pitch series is used across Honda, Yamaha, Kawasaki, and Suzuki main harness junctions. Verify pin count and wire gauge against your model’s wiring diagram before installation.
Q: When should I use unsealed vs. waterproof for a 7-pin connector?
A: Use unsealed for protected under-fairing, frame-mounted junction box, or instrument panel locations. For exposed underbody, handlebar, or tail section locations subject to rain and wash-down, specify the sealed waterproof variant.
