Data Link Connector
WARNING: This page is about a different car, the 2003 Dodge Dakota. However, it is still accessible from the selected car via links, so may be relevant.
The data link connector is located at the lower edge of the instrument panel near the steering column. The 16-pin data link connector (diagnostic scan tool connector) links the Diagnostic Readout Box DRBIII(R) scan tool or the MOPAR Diagnostic System (MDS) with the powertrain control module.
