What our customers are saying:

I was extremely pleased with my recent purchase of a prodigy brake controller. I ordered it on a weekend, and it shipped first thing Monday. I found your site by doing a google search on installing a brake controller for my 2003 GMC Envoy. I was thrilled to find a video for installing on an 2004 Envoy so watched it. It was a quick and easy install. Thanks so much.

Our control box is going to be mounted down on our kick panel or in your center console. Here's what it looks like once it's installed. You have your display unit. As you can see on our control panel we're going to have a nice manual switch.
