Confirmed Vehicle Applications

This connector is not exclusive to a single vehicle, but it is commonly found in:

- GM LS-series coil packs – used in LS1, LS2, LS3 engines
- Toyota TPS and ignition systems – especially in 3S-GE, 4A-GE platforms
- Nissan CAS (Crank Angle Sensor) – round and square variants, found in SR20DET, RB25DET engines
- VW MP9 water temperature sensors – used in Golf, Polo, and Caddy models
- HOWO A7 trucks – speed sensor and odometer interface

This connector is part of a standardized design used across Opel, Toyota, Nissan, VW, GM, and Chinese truck platforms, especially in models from the late 1990s to early 2010s.
