This is only for OEM headlights not aftermarket headlights.

This is the harness needed when installing the 2016-2018 1/2 Ton SLT (Denali) headlights into your 2014-2015 SLT/DENALI Sierra (lights that currently have the LED strips). This harness is for the LED headlight that utilizes the LED turn signal. Harness come with load resistors, as they are needed to prevent the hyper-flash caused by LED turn signal bulbs. See below picture's showing which headlight this harness is for. This version of the harness will leave the "C" DRL on when the turn signal is turned on, unlike GMC factory operation, which turns the "C" off when the signal is used during the day.

Will not work on 2014 (2500/3500 models)
