I just accepted delivery of Model Y in the beginning of June with the express purpose of towing my Safari Alto F2114 camper. I ordered it with the towing package. It is replacing a 2019 Subaru Ascent. I have seen some discussion that the Auxiliary power back to the camper was disabled when Tesla introduced the Lithium low voltage battery to replace the lead acid battery. No one I have spoken with at Tesla has heard of this. The article was written in early 2022. Does anyone know if the auxiliary power pin on the 7-pin socket is now enabled? Is it a software update, or is there a hardware upgrade required?
Better yet - If someone out there is towing with a model Y and is using a brake controller and sending power back to a camper, please respond and let me know how you did it.
