A vision system for a vehicle includes a camera configured to be disposed at a vehicle so as to have a field of view exterior of the vehicle. The camera includes a printed circuit board, a lens and a camera housing, with the printed circuit board disposed in the camera housing. The printed circuit board is attached at the housing via an electrically conductive fastener that passes through an aperture through the printed circuit board and that engages a connector portion of the housing. A head of the fastener electrically engages circuitry at the printed circuit board and an end of the fastener electrically conductively connects to an electrically conductive pin at the connector portion of the housing. The connector portion of the camera housing is configured to electrically connect to a connector of a vehicle wiring harness when the camera is disposed at the vehicle.
