This image showcases a standard 4-pin automotive electrical connector, widely used in modern vehicle wiring harnesses. The connector features:

- Four circular pin slots, clearly labeled 1 through 4 for easy identification and wiring alignment.
- Durable dark plastic housing, designed to withstand heat, vibration, and moisture typical in engine bays.
- Secure locking mechanism (not visible but typically present), ensuring a tight and reliable connection to sensors or modules.

These connectors are often found in systems such as:

- Ignition coil packs (e.g., GM LS1, Toyota, Opel Corsa)
- Throttle Position Sensors (TPS) (e.g., Toyota)
- Crank Angle Sensors (CAS) (e.g., Nissan round or square type)
- Water Temperature Sensors (e.g., VW MP9)

Because this connector type is standardized across multiple manufacturers, visual identification alone isn't enough to pinpoint the exact vehicle model. To determine the precise application, you'd typically need:
