## Customer Reviews

### ⭐⭐⭐⭐⭐ Excellent Product

Excellent product; easy to install.

### ⭐⭐⭐⭐⭐ Worked great for my Sequoia
*by J***S on March 19, 2025*

Just what I needed to make installing a brake controller on my 1st Gen Sequoia plug and play.

### ⭐⭐⭐⭐⭐ Factory fit/quality
*by G***D on October 15, 2025*

Perfect fit for my 2007 sequoia to be able to add a trailer brake controller. The wire was just long enough to hide the unit on the right side of the steering wheel and it’s tucked out of the way of legs/knee.
