I've done some searching and I'm a little unclear about this. Most of the stuff I read was referring to the Promaster City. I understand there is Rostra aftermarket cruise control available but I'm wondering if I can add factory cruise control? It looks like I would have to remove the entire column that has the light switch as well as the wiper switch. Then I need to replace it with the column that includes the cruise switch on it. I'm wondering if anyone has done this and if the wires are there to connect everything and make it work. I have a 2016 2500 159'' and it did not come with CC. Thank you for the help.
