How to Install a Trailer Hitch to a 2014 to 2019 Toyota Highlander

A trailer hitch connects a trailer to your vehicle and allows it to haul large loads. Hitches may come standard for some vehicles, but other cars may need one installed. Today, we’ll be installing a trailer hitch to a 2017 Toyota Highlander, and procedures will be similar for all Highlander models from 2014 through 2019.

Before you decide on a trailer hitch, make sure your towing class corresponds with the capabilities of your vehicle. For safety reasons, you should never haul anything that exceeds the towing capacity of your hitch or your vehicle.
