14-15 Sierra SLT to 16-19 HD Headlight Harness

 This is only for OEM headlights not aftermarket headlights.

This harness is for those with 2014 and 2015 GMC Sierra SLT models that want to upgrade to the 2016-2019 HD(2500&3500) HID headlights. The 2016-2018 HD headlights look identical to the the 2014-2015 SLT headlights except they utilize a HID bulb for a much brighter and functional look. This harness provides the "clean power" needed to run the GM HID bulbs.  For use with these 16-19 HD headlights.

Will not work on 2014 (2500/3500 models)
