Frequently Asked Questions

What is the difference between 7123-7960 and 7122-7960?

7123-7960 is the male plug housing (accepts male pin contacts); 7122-7960 is the female receptacle housing (accepts female socket contacts). The plug connects to the receptacle to form a complete sealed connector. For replacement of a damaged connector half, order only the damaged half. For a complete new connector assembly, order both the plug and receptacle.

What contacts are compatible with Yazaki 71XX-series connectors?

Yazaki 71XX-series connectors use Yazaki-specific contacts. Cross-reference the connector part number in the Yazaki catalog or Toyota/Honda parts catalog to identify compatible contact part numbers. Common Yazaki contact sizes for 16-pin connectors: 0.64mm, 1.2mm, or 2.0mm pitch depending on the specific connector series.

How do I repair a Yazaki 16-pin connector?

Individual terminal replacement: (1) use a Yazaki-compatible terminal extraction tool; (2) cut the wire behind the damaged terminal; (3) crimp a new terminal using the correct Yazaki crimp tool; (4) reinsert until the locking lance clicks; (5) verify seating with a pull-test; (6) reinstall the back cover. For Toyota vehicles, the Toyota Repair Manual specifies the extraction tool and replacement procedure.
