1. A rearview mirror reflective element assembly for an exterior rearview mirror assembly suitable for use on 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 said mirror reflective element;

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

    wherein said electrically conductive traces comprise (i) a heating trace that, when powered, heats said heater pad substrate and said mirror reflective element, (ii) electro-optic control traces that, when electrically powered, darken said mirror reflective element, and (iii) an accessory trace that, when powered, controls an accessory of said mirror reflective element assembly;

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

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

    a back plate formed by injection molding of a polymeric material;

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

    wherein said back plate comprises a connector portion having electrically conductive elements that are electrically conductively connected at respective terminals of said electrically conductive traces of said heater pad;

    wherein said connector portion is one of (i) insert molded in said back plate during injection molding to form said back plate and (ii) insert molded into a connector element attached at the heater pad;

    wherein said connector portion is configured to electrically connect to a single wiring harness of the exterior rearview mirror assembly; and

    wherein said accessory trace, when powered, controls a blind zone indicator that is disposed at the rear of said mirror reflective element and that is viewable, when powered, through said mirror reflective element.
