An electrical connector (100) comprising a housing (200) defining a front face and a first mating cavity recessed rearward from the front face for receiving a modular plug, an electronic module (400) mounted to the housing, a horizontal PCB (500) mounted under the electronic module, and an outer shell (700) shielding the electronic module and the housing. The electronic module has a vertical PCB(420) which includes a ground trace (421) joined to a conductor (427) that extends through a plated hole in the vertical PCB and that is connected to a conductive pin (722) of the outer shell through a conductive trace (56) of the horizontal PCB (500).
