This harness will remove DRL function from your headlamp and can either leave it so your Sierra has no DRL's or we can make it so your fog lights become your DRL's.
If you choose to have your fog lights as your DRL's you also have the option of keeping the fog lights on with the highbeams. This harness is needed when installing HID or LED headlight bulbs into your GMC Sierra as there is less voltage during DRL mode which can play havoc with the HID and LED bulbs.
This harness is intended for 2014 (1500) -2015 (All) GMC Sierra's without the SLT package. If you choose to move the DRL function to your fog lights, your fog lights will still operate properly at night via the factory switch. This harness allows for normal headlight function at night except that you will lose the ability to have just your parking lights on. Anytime the parking lights are now on, your headlights will also be on.
If you plan on running HID fog lamp bulbs please contact us before ordering as we can make a custom harness that will power those as well. If you are planning on running either stock flog lamp bulbs or LED fog lamp bulbs, our harnesses will work fine.
Will not work on 2014 (2500/3500 HD Models)
May not work on Canadian models. Please contact us if you have a Canadian model Sierra to confirm fitment before ordering.
PLEASE PROVIDE YOUR VIN # AT CHECKOUT AND WE WILL VERIFY THE MODEL OF YOUR CURRENT VEHICLE
Follow the above and there is one more connection point that goes in between the bumper harness and body harness, this connection point is located behind the bumper near the center point on the passenger side. Simply unplug and plug our harness inline and re-connect.
