This is a 4-pin sealed automotive connector designed for engine bay applications. It features a rectangular-oval housing, a top locking tab, and a prominent orange rubber weather-seal that ensures strong protection against moisture and contaminants. The terminal layout supports four low-voltage signal or control wires, making it suitable for sensors and actuators found in modern fuel-injected engines. Its durable design allows it to withstand high temperatures and vibration, making it ideal for critical engine management components.

Its design — including the oval shape, top latch, and front orange weather-seal — is characteristic of connectors used by manufacturers such as:/Ford/GM / Opel / Chevrolet/  VW / Audi/ Hyundai / Kia/Toyota (newer models)
