Sumitomo 6189-7073 (Toyota 90980-12572) 2-Way Female 025 Connector

The Component: Genuine Sumitomo Wiring Systems TS Sealed Series 2-way female plug connector housing / Direct Cross-Reference: Toyota OEM Part Number 90980-12572 / Features an ultra-compact 2-position single-row layout configuration / 0.64mm (025) micro sealed terminal socket footprint / Built-in front alignment locking plate serving as terminal position assurance (TPA) / Premium heat-stabilized Dark Gray Polyamide composite plug body / Weatherproof inline sensor-to-harness socket connection / Component Part Number: 6189-7073 / Toyota Order Reference: 9098012572.

Applications & Fitment: Engineered to establish an exceptionally precise, low-profile, and completely weatherproof electrical link within dense automotive engine architectures where space is highly constrained. This authentic Sumitomo 2-pin female plug (alternatively cataloged under Toyota genuine reference 90980-12572) is a widespread factory standard across multiple generations of Toyota, Lexus, and Scion vehicle wiring looms. Utilizing an ultra-compact micro 0.64mm terminal profile arranged in a straight 1x2 configuration, it is explicitly specified to interface with low-current under-bonnet automotive components—most notably factory windshield washer pump motors, exterior ambient air temperature sensors, variable valve timing (VVT) solenoid actuators, and select automotive horn assemblies.

Molded from premium, impact-resistant Polyamide nylon, the heavy-duty plug shell maintains long-term structural integrity and robust latch-arm spring tension under extreme engine bay thermal cycles. The housing features an integrated internal front alignment mask that acts as a secure terminal lock barrier, preventing terminal backing forces from displacing the electrical connection. Complete environmental isolation against oil, chemical solvents, road salt, and high-pressure water spray is achieved via an internal silicone perimeter seal combined with individual 0.64mm single-wire seals (SWS). Highly favored by professional motorsport loom builders, diagnostic auto-electricians, and custom automotive wiring harness specialists demanding factory-correct connector replacements.
