Parts Needed to Install 7-Way and Brake Controller in 2017 Toyota Sienna  

Updated 07/30/2020 | Published 07/29/2020

Question:

I have a 2017 Sienna LE and need to install a wiring harness, 7-way receiver, and brake booster. I currently have a Curt Venturer brake booster and a Pollak 7-way reciever. What do I need to complete this install?

Expert Reply:

We can help you install your Curt brake controller but you won't be able to use the 7-way harness you have currently as that looks to be custom fit for a different vehicle.

You will need to start with a 4-way (if you do not have one). For that you would want the # 118648.

From there you would need to convert the 4-way to a 7-way so that you can install the brake controller. For that you will want the Brake Controller Install Kit and 7-Way Adapter part # ETBC7. I attached installation instructions and an install video for this product as well.
