An electric winch control module of this disclosure provides improved means for detecting changes in a current carried by an electric winch motor power lead. The module's housing includes a magnetic flux shield contained within an exposed channel of the housing and located at or toward a vertical centerline of the channel and opposite a magnetic flux sensor of the control module. The magnetic flux shield is made of a ferromagnetic material and includes a bottom wall spanning the width of the open bottom of the channel, an open top arranged opposite the top wall of the channel, and opposing sidewalls opposite a respective sidewall of the channel. The shield surrounds the side and lower portions of the lead below the sensor when in the channel, shielding the wire and sensor from outside interference while at the same time exposing an upper portion of the lead to the sensor.
