It comes with the curved trim piece that you need to install the factory hitch. If you don't have the wiring harness already then you have to buy the Toyota harness and module as well. It can be found on the same page as well if you scroll down
I looked at all those options. I am cheap when it comes to some stuff sooo..... i'll just make my own. I was really hoping to just find something cheaply priced and already engineered to tow with, and bolt on. In my search I have see what is out there and I feel like I can do as good. if I remember I'll post a pic when it's done.
