For sale here is a universal trailer wiring harness that fits on Tesla model Y or Tesla model 3. I fully intended on using this harness until I ripped apart my Tesla to find it already came with wiring that I didn’t realize it had.
This harness has never been used and is super cool because you can install it without having to cut any wires on your car whatsoever.
I am including a picture to this same harness for sale on Amazon for $175. I am just trying to recoup a small fraction of the money I just paid for it a few weeks ago. For $10 this is a steal and it won’t last long at this price. Text me or call me if you are serious.
