A vehicular accessory module includes a circuit board and a metal enclosure. An electrically conductive grounding contact affixed at a first side of the circuit board and electrically connected to circuitry at the circuit board. The grounding contact is disposed between and contacts both the first side of the circuit board and the metal enclosure to provide an electrical connection between the circuit board and the metal enclosure. The grounding contact includes an abrasive surface that is in contact with the metal enclosure. Movement of the grounding contact relative to the metal enclosure causes the abrasive surface to scrape the metal enclosure to enhance grounding of the grounding contact with the metal enclosure.
