I have a 2021 pro4 . Trying to find a plug and play for a hopkins controller. The problem is the part stores say there isn't one for any model controller. What changed between 18 and 21? The connector underneath the steering column looks the same. I went as far as calling the dealership and they couldn't tell me either. Sent an email to Nissan and haven't heard from them either. Has anyone else hooked up brake controller on newer model?
