Sumitomo 6189-1240 TS Series 8-Way Female Sealed Plug

The Component: Genuine Sumitomo 6189-1240 8-way female automotive sealed connector housing plug.

TS Sealed Series 025 (0.64mm) 8-position dual-row socket receptacle casing (Grey / PBT / Sealed / Inline Housing / Part Name Alias: 12520WQA08F-GR / Toyota Cross-Ref: 90980-12520).

Applications & Fitment: Designed as a primary factory original equipment (OE) wiring harness repair solution for highly sensitive, low-voltage automotive sensor arrays and exterior chassis control networks. Most notably specified across global vehicle manufacturing platforms (including Toyota cross-ref: 90980-12520, Subaru cross-ref: 99801FN150, and Ford Motorcraft pigtail service kits: WPT-1349 / DU2Z-14S411-TA) as the definitive interface for electronic throttle bodies (ETB), rear bumper parking sensors, reversing radar grids, and compact fuel injector loops. Highly vulnerable to primary plastic locking thumb-latch snapping from brittle aging under chronic chassis road-grime exposure, or internal channel wall distortion if back-probed carelessly during field workshop diagnostics.
