Designed for the "Do It Yourself" crowd, the 103028 Connector Kit contains a gray 2-way connector used on the Air Temp Sensor, known as "AIT" or "ATS", and a mating connector. The mate is a solder-type molded connector and the pinned connector is the "Pull-To-Seat" style which means you must first push the wire thru the connector, crimp the terminal, then pull the wire back into the connector to seat the terminal. Comes with P2S female terminals. Note: Double D style crimp tool is recommended.
