Unless you are experienced and have done an installation like this a few times I would strongly recommend hiring out for a job this complicated. I have worked on cars my entire life and I wouldn't mess with the wiring systems on these new vehicles.

You will need two sets of wiring harnesses since they don't make just a 7-way harness that can be added to your 2024 Toyota Grand Highlander. Additionally, there is no plug in adapter for a brake controller so unless you're using one like the Curt Echo item # C51180 you will need to cut into more wires.

I can help you find an installer in your area that is a part of our network. You will want to scroll down to the left side of the product page item # C26VV and go down below the pictures. There you will find a link that says, Locate installers near me. You will want to input your zip code to get a list of reputable installers near you.

To tow a trailer with brakes with your 2024 Toyota Grand Highlander you will need the following parts:

Trailer Hitch - Curt Hitch item # C26VV

4-Way Wiring Harness - Curt Powered Tail Light Converter item # C59236

7-Way Wiring Harness - Universal Installation Kit for Trailer Brake Controller item # ETBC7

Wiring Harness Mount - No-Drill Mount Bracket item # 18136

Brake Controller - Redarc Tow-Pro Liberty Brake Controller item # RED24FR and Wiring Adapter item # RED69FR

Ball Mount - Curt Towing Starter Kit for 2" Hitches item # C45534
