Hi folks,   I have a 2017 hatch sportline, fancied a reverse camera, but decided I would install at the same time as a proper wiring kit for tow bar (7 pin).   I have both kits fully wired up now, but have a lot of issues! Not sure if I can code them all out or not… I have OBDII.   the tow bar wiring is working, I.e. light board works fine.  but there is nothing showing camera is operational, my park assist is totally disabled. Although I note from moving the car,
