If you are doing a front end conversion, this harness is the Plug and Play Harness you’ll need to complete the headlight conversion.  This harness will offer a truly GM Factory operation of your new GM FACTORY headlights.  You will retain the ability to use “Park Lamp” mode on your headlight switch.  Your DRL strips will also behave like GM Factory.
