14-15 Sierra NON SLT to 2016-2018 1/2 Ton SLT LED Headlight Harness

 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 SLE Sierra. 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.  Please note that with this harness installed you will lose the ability to have just your parking lights on.  If you manually turn your headlight switch to the parking light position, the headlights will also come on.
