4-Pin 6.3mm Series Unsealed Female Motorcycle Connector – OEM PH776-04015
Direct OEM-specification replacement for the 4-way 6.3mm pitch unsealed female connector, cross-referencing part number PH776-04015. The 6.3mm pitch series is the standard for higher-current motorcycle circuits including lighting, ignition, and charging system connections where larger wire gauges are required.

The 6.3mm pitch series accommodates heavier gauge wire (1.25mm² to 3.0mm²) required for higher-current motorcycle circuits. Common applications include main power distribution, lighting relay, and charging system connections where 1.5mm or 2.8mm pitch terminals would be undersized. The larger terminal cavity provides superior crimp retention and lower contact resistance under sustained current load.
1 × 4-Way Female Connector Housing (PH776-04015, 6.3mm pitch) with wire leads and terminal inserts pre-installed.
Q: What is the mating male connector for PH776-04015?
A: The mating male housing uses the same 6.3mm pitch series. Verify pin layout and terminal size against your wiring diagram before ordering the male counterpart.
Q: What wire gauge does the 6.3mm terminal accept?
A: The 6.3mm series terminal accepts 1.25mm² to 3.0mm² (16–12 AWG) wire. Use a ratchet crimping tool with the correct 6.3mm die for proper crimp height and terminal retention.
Q: Is this connector suitable for a 30A circuit?
A: The 6.3mm terminal is rated for up to 30A depending on wire gauge and ambient temperature. Verify against your circuit’s fuse rating and wire gauge before installation.
