WARNING: This page is about a different car, the 2017 Fiat 500L. However, it is still accessible from the selected car via links, so may be relevant.
The Data Link Connector (DLC) (1) is a 16-way molded plastic connector insulator on a dedicated take out of the instrument panel wire harness. This connector is located at the lower edge of the instrument panel, outboard of the steering column. The connector insulator is retained by integral snap features within a rectangular cutout in a mounting bracket located just under the lower edge of the instrument panel, directly above the hood release.
