2019 Ram 2500 HD 6.4l HEMI. I want to add some auxiliary switches onto the standard switch bar next to the tow haul and traction control. I am looking for a part to either add on toggle switches if that is possible (looks like they have filler bars in them now) or for a whole new toggle unit with tow haul, traction control and the rest being auxiliary toggles. I have heard conflicting info that this is possible. Some say all that will need to be done is to have ram “reprogram” the ecm and some say it can’t be done without spending thousands to change a bunch of stuff. Any idea?
