Newer design. At first I thought wouldn't be able to use on my 2015 ram 3500. Old one pops off. New one although an updated and different plastic snap design, worked just fine. Remove two wires to heater before popping old mirror off. It it to the side to access them. You have to remove three metal clips off old mirror to reuse on new mirror. There is a u tube vid that also helps describe the different style mirrors. Lil scary thinking I was going to crack new mirror. I would recommend some leather gloves just in case your old one splinters while popping it off. Hope this helps and good luck !
