Surely, if you purchase the audio control switch and find the right harness it will work. It is my understanding that they all are made the same from the factory.Besides that, many 1500 and 2500 parts are interchangeable. It's the electrical wiring, packages and features that they add later is what makes a Lt, a Lt and a high country High Country. Almost any feature can be later added. However, most of the time a harness is needed to make it work. I just purchased the 2020 Silverado HD tow mirrors and had the dealer install them on my 2019 work truck.It needed an additional harness to make the turn signal and lightening work.I too purchased the work truck and slowly added factory add ons as I go.The fog lights , the bed lights, console cover, and tow mirrors has been added.Doing this way I've save a ton of money.Kinda, pay as you go without the finance . Besides that, it makes the truck unique. People are constantly asking me, is your truck a 2500.
