See my earlier post, I bought the e trailer aftermarket wiring harness (returning same) which is about the same cost as the ORM part BUT the aftermarket unit requires you to splice into the cars tail lights wiring harness, it’s not plug and play. All GV80 are pre wired for towing so there’s a connection point somewhere on the car to allow for the factory hitch wiring pigtail (purchased separately) to be easily connected and then functions correctly with the cars main system and, I suspect as on my Audi, let’s you know for instance if a trailer lights are malfunctioning etc? Question is how and where to purchase this OEM wiring 9 pin pigtail harness since local Genesis Hyundai dealer in Florida seem to be clueless and offer no help.
