Most Popular Trailer Brake Controller for 2010 Lexus RX 350

This kit allowed me to hook a 2015 Lexus RX 350 to a trailer with a 7-way trailer connector. The instructions were great along with the videos. Finding the brake wire in the RX 350 is darn near impossible, but I got to it after a great deal of trial and error, and patience. The etrailer team was helpful when I emailed them -- both to find the right kit (this one) and with help on finding the brake wire (they sent a link to a video).

All the parts necessary to hook up a 7 pin and 4 pin to my Lexus RX 350 with tow package, to the vehicle and the new brake controller. Everything works fine!

The products I ordered arrived quickly with no problems. The included installation instructions were clear and easy to follow. The installation videos on the e trailer website were also very helpful. The result was an easy do it yourself install. Products worked perfectly. Would definitely recommend etrailer.

I received an adapter for the wrong year Toyota Tacoma. Still sitting in the box in my shop. I didn't get to the project until it was probably too late to return the product

Etrailer said I needed this part for my Lexus RX 350 with tow prep package wiring for trailer towing. My Auto mechanic used all the parts Etrailer said I needed and everything works fine!

Easy to use, accurate for my application

This controller has worked flawless for me. I’ve used it on a 2009 Lexus RX350, 2022 Lexus RX350, and 2022 Lexus GX460. Never an issue connecting or operating. My father, on the other hand, has the exact controller for use with his 2018 Ford F-150, and has had many issues with connection and operation. I love it’s modularity and simplicity.
