What Tekonsha P3 Brake Controller do I Need for My 2020 Toyota Highlander, and Wiring?
Updated 09/29/2025 | Published 04/25/2025
Question:
Hello, Im the owner of a 2020 Toyota Highlander without the towing package. Originally, I was planning to purchase only the TK57VR, but my plans have changed and I’ve decided to install a brake controller as well. Many people recommend the Tekonsha 90195 Prodigy P3, and since I’m planning to upgrade my vehicle in 2–3 years, I’d like to invest in a high-quality model now. So Im considering purchasing the TK63VR. Are there any additional items I should buy or things I should consider before moving forward? Thank you in advance!

Hello Ethan,
The Tekonsha Prodigy P3 Trailer Brake Controller - 1 to 4 Axles - Proportional # 90195 is an excellent choice and my go-to recommendation. I've set-up many friends and family members with this controller, and the feedback has been consistently great. You will need to splice in the controller since the 2020 Highlander does not have the vehicle specific pigtail.
Since your 2020 Toyota Highlander did not come with the tow package, it likely does not have the necessary wiring at the rear of the vehicle. To get everything set up, you’ll need the Tekonsha OEM Replacement Vehicle Wiring Harness with Brake Controller Adapter - 7-Way Trailer Connector # TK57VR. This harness will give you a functional 7-way connector and allow you to properly use the brake controller.
I should mention that installing the harness can be fairly involved, especially when it comes to the wiring work. We haven’t installed one yet here at etrailer, so there isn’t an install video available at this time. However, I’ve attached the instructions for you to review.
If you'd like, you’re welcome to bring your Highlander by our shop here in Wentzville, MO. We'd be happy to handle the installation for you so we can have the content on our site.
Does your Highlander have the 7 way on the back?

Hey Ethan, did you have a chance to check if your Highlander has the 7-way connector on the back? I'm asking because knowing this could help others in a similar situation.
