I am installing the Mopar trailer wiring kit on a 18 JLU Sport and have read you need to have a dealer flash once it is installed to enable the trailer sway dampening HOWEVER I noticed on my build sheet that trailer sway dampening is already listed. Anybody have experience installing this aftermarket? Is the flash needed if listed already?
