Recommended Brake Controller and 7-Way Wiring for 2022 Toyota Sienna XLE  

Question:

I need to add a brake controller and a 7 pin connection to my Sienna so I can use the brakes on my trailer. I want something that is relatively easy to install. It is a 2022 XLE if you needed to know, thanks.

In order to add a 7-way to your 2022 Toyota Sienna XLE you will need to start by adding a 4-way connection. We have found Tekonsha to be the most reliable when it comes to a 4-way wiring harness so I recommend the T-One Vehicle Wiring Harness # TK69FR. This will plug into connection points in your rear cargo area using the T-One connector.

Once that is done you will need to add your 7-way. Since you're looking for an easy installation I recommend the 7-Way RV Upgrade Kit for Trailer Brake Controller Installation # ETBC7L. This kit will allow you to use a trailer brake controller that pulls power from the 7-way instead of having to connect to wires inside your vehicle. Should you decide to use a different brake controller that requires installation inside your vehicle, you will want the # ETBC7 instead.

Once this is installed, you will be able to use the Curt Echo Wireless Trailer Brake Controller # C51180. This proportional brake controller plugs in line with your 7-way at the back of your vehicle. No additional wiring or installation is necessary. The Echo is controlled via Bluetooth through the app on your smartphone. The app lets you use the manual override and adjust the braking power, as well as store multiple profiles. Should your phone die, the brake controller continues to operate normally using the current settings.

I have attached some review and installation videos for your reference.
