This is only for OEM headlights not aftermarket headlights.
For those that wish to add the 2014-2015 GMC SLT headlights, or the 2016-2019 2500/3500 HD headlights to their 2014-2015 Non SLT Sierra, this is the needed harness. This harness is a complete plug and play harness which utilizes 4 relay's for controlling all function's. Harness simply plugs inline between the original headlamp connector and the new headlamp along with a power source from the under-hood fuse block and battery. Harness will allow for same function as a true SLT model, except as noted below. Bottom LED will now be the DRL's. Top and bottom LED's will be on at night. This harness can also be used to install the 2016-2018 3/4 HD HID headlights into your 2014-2015 Non SLT. The 2016-2018 HD model headlights look identical to the 14-15 SLT headlights, except they utilize a HID bulb.
With this harness you do lose the ability of just running around with your side markers, amber lights, on by themselves. If you manually turn your headlight switch to the side marker position you will also have headlights, this is normal operation with our harness installed.
