FAQ
Q: What is the difference between 6520-1466 and 90980-11880?
A: 6520-1466 is the Yazaki manufacturer part number, while 90980-11880 is the Toyota OEM part number for the same 3-pin 7.8mm connector housing. They are identical and interchangeable.
Q: Why use a 7.8mm pitch connector instead of 6.3mm?
A: The 7.8mm pitch supports higher current per pin (~30A vs ~25A for 6.3mm) and accommodates larger wire gauges. It is used for the highest-current motor and power distribution circuits in Toyota vehicles.
Q: What terminals are compatible?
A: Yazaki 7.8mm series female terminals for 1.0–6.0mm² (AWG 18–10) wire. Terminals are sold separately.
