I have a 2017 express, i added my own controller(oem) from amazon , also got the switch thats oem too, very easy to install but need to turn function on the bcm, either tru dealer or with an. Alphaobd.I am really loving my new truck of three weeks. Towing was very low on the priority list when I bought it. It does have the class 4 hitch. Sooner or later I will need to tow an RV and will need electric brakes. Anyone had experience with adding one on after market? Thanks!
