    There are (2) diagnostic connectors on your vehicle. The one for the Engine Single Board Engine Controller (SBEC) is located under the hood on the passenger side. It is a 6 pin Black connector. The Transmission Control Module (TCM) diagnostic connector is located under the drivers side of the instrument panel, to the right of the steering column. It is a BLUE connector.
