Expert Reply:

The easiest way to determine if your 2019 Toyota Highlander has a towing package with a converter is to remove all of the floor coverings on the inside rear of the Highlander. You will need a trim panel removal tool part # ALL648544 or a flat head screwdriver. If you have the factory package with a converter you will already have a black box with wiring against the wall of the rear cargo area like I have pictured.

If you already have the converter, the Curt T-Connector Wiring harness for Highlanders with the towing package part # 56042 is needed. This kit does not come with the Converter because you already have it. I have attached a video for your reference.

If you do not have the converter, the Curt T-Connector Vehicle Wiring Harness for Highlanders without the towing package part # C56217 is needed. This kit comes with the converter that you need because the Highlander did not come from the factory with it. It also comes with the fuses needed to activate the towing functions. I have attached a video of this for your reference.

You can also take your VIN to the dealership and have them determine if the Highlander has a tow package if you don't want to take the panels out. You could also just use the C56217 and not use the converter if you end up having it already.
