A rearview mirror assembly for a vehicle includes a mirror casing and an electro-optic reflective element assembly disposed at the mirror casing. A second surface of a front substrate of the reflective element assembly has a transparent conductive coating established thereat and a third surface of a rear substrate has a conductive coating established thereat. An electrical connector may be disposed at the fourth surface and in electrically conductive continuity with the transparent conductive coating and/or the conductive coating. The electrical connector may include a connector attaching portion for attaching at the fourth surface and a conductor attaching portion for soldering or welding an electrical conductor or wire to the electrical connector when the electrical connector is attached at the fourth surface. The conductor attaching portion is spaced from the plane of the connector attaching portion and the fourth surface of the rear substrate.
