1. A rearview mirror reflective element assembly for an exterior rearview mirror assembly for a vehicle, said mirror reflective element assembly comprising:

  • a mirror reflective element, wherein said mirror reflective element comprises an electro-optic mirror reflective element operable to vary its reflectivity of light responsive to an electrical voltage applied at first and second busbars of said mirror reflective element;

    a heater pad comprising a heater pad substrate having a plurality of electrically conductive traces established thereat;

    wherein said heater pad substrate is disposed at a rear surface of said mirror reflective element;

    a back plate, wherein said heater pad is disposed between said mirror reflective element and said back plate;

    wherein said electrically conductive traces comprise (i) a heating trace that, when powered, heats said heater pad substrate and said mirror reflective element, (ii) first and second electro-optic control traces that, when electrically connected to said first and second busbars and when electrically powered, darken said mirror reflective element and (iii) at least one accessory trace that, when powered, controls an accessory of the exterior rearview mirror assembly;

    wherein said electrically conductive traces terminate at a connector region of said heater pad substrate;

    an electrical connector established at said connector region and having terminals electrically conductively connected at respective terminals of said electrically conductive traces, wherein said electrical connector is configured to electrically connect to a single wiring harness of the exterior rearview mirror assembly; and

    wherein said electrical connector is formed as part of said back plate during injection molding of said back plate.
