WARNING: This page is about a different car, the 2015 Fiat 500. However, it is still accessible from the selected car via links, so may be relevant.

The Body Control Module (BCM) receives the input from the Left Multi-function Switch requesting park lamp illumination. The BCM provides a voltage output through the side marker control circuit. The control circuit connects to the Park Lamps. A ground path for the lamps is present through the harness to the body sheet metal. For additional information on the Park Lamps operation.
