Reddit reviews Tow Ready 118151 Wiring Kit for 3 Power Modules

I have this one and I love it! It required some drilling to install, but with a new drill bit, the drill goes through like butter. My trailer is pretty small, so I could easily get by with a Class I hitch, but I like having the Class II because you never know. I realize the car isn't rated for towing, but this car is easily capably of towing a small trailer. For the wiring, I bought this and this which wasn't too bad to install. I had to remove quite a bit of trim and stuff from the back to get at everything, and then I routed the output wire to the area behind the little battery door, so I can just remove that little door to get at the wires.

All in all, I love this hitch. You can barely see it from behind, and it has almost no impact on the foot-activated liftgate, other than in the absolute center of the rear bumper.
