14-18 Sierra LED Fog Light Adapter Harness

 This is only for trucks that came Factory equipped with OEM fog lights NOT dealer or aftermarket installed fog lights. For those of you with 2014/2015 and 2016-2019 HD Sierra's that have factory fog lamps and want to install the 2016-2018 LED version, this is the needed harness to do a seamless conversion.  This plug and play harness simply goes inline with the original bumper to body harness and has new leads coming off of it to connect to the new fog lights.  Fog light control will still be via the stock switch.   Will not work on 2014 (2500/3500 HD Models) Overview:
