A variable reflectance mirror reflective element assembly for an exterior mirror assembly includes a heater pad disposed at the fourth surface of the rear substrate. The heater pad includes a first connector that electrically connects with the transparent electrically conductive coating disposed at the second surface of the front substrate, and a second connector that electrically connects with the metallic electrically conductive coating disposed at the third surface of the rear substrate. The heater pad includes third and fourth connectors that provide, at least in part, electrical conductive connection with a heating element. The connectors are part of a unitary multi-pin connector that is configured to connect with a corresponding wire harness connector to provide electrical power to the heating element and to the transparent electrically conductive coating and the metallic electrically conductive coating of the reflective element when the exterior minor assembly is mounted at the vehicle.
