2-2-4-0T

The term "2-2-4-0T" describes a specific type of electrical connector, often used in automotive applications, particularly in connection with throttle position sensors (TPS) or other engine management components. The numbers refer to the pin configuration and potentially specific signal assignments within the connector.

Specifically:

• 2-2-4: Indicates a connector with two rows of pins, containing 2 pins, 2 pins, and 4 pins respectively. Therefore, the connector has a total of 8 pins. The order (2-2-4) likely refers to the physical arrangement of these pins within the connector housing.
• 0T: The "0T" suffix is less definitive but typically signifies a specific manufacturer, series, or technical specification of the connector. The "T" often indicates that it's a sealed connector (weather-tight) used in harsh environments common in automotive under-hood applications. This is a convention but is not a universally followed standard. It may also indicate something related to the pin material or plating.

Because "2-2-4-0T" is a descriptive term, its exact meaning and pinout are highly dependent on the specific context of its use, the vehicle manufacturer, and the specific engine control system it's connected to. Identifying the specific application (e.g., the specific model and year of a car) is crucial to determining the pinout and functionality of each pin within the connector. The manufacturer's datasheets for the connectors would provide more detailed specifications.
