Will # TK99FR Work if There is a Tow Package in Place on 2021 Toyota Highlander

Question:

Toyota makes it very difficult to determine if a trailer wiring package is included on the 2021 Highlander L Trim. We are about to buy one. Two seemingly identical except for color vehicles. One, the dealer lists in the description as tow package even though there is no factory hitch. The other omits this designation. Checking with the Toyota Vehicle Specifications web site on both of them, NEITHER show any mention of the tow wiring. So, my question is: will this work on a Highlander even if the factory towing package is installed?

The T-One Vehicle Wiring Harness with 4-Pole Flat Trailer Connector # TK99FR will work with both models. If you have the factory tow package, you just use the harness that has the 4 pole connected to it. If you do not have a factory tow package, you will need to use both of the wiring harnesses as your vehicle is not set up with a converter box to power the trailer lights.

We have hitches available for the 2021 Toyota Highlander also. I recommend the Curt Trailer Hitch Receiver # C99FR.
