Tekonsha ZCI Circuit Protected Vehicle Wiring Harness Installation - 2017 Mercedes-Benz GLS- Video

Hi there, Mercedes owners. Today in your 2017 Mercedes GLS 450, we're gonna be taking a look at and showing you how to install Tekonsha ZCI 4-pole flat trailer connector wiring system. And this is what our harness looks like when it's installed. It is designed to live inside the vehicle. So when you use it, you'll simply pinch it between the lift gate here at the back and it will drape down and then you'll hook up to your trailer and head on your way. Our 4-pole connector here is gonna provide us with all of our necessary lighting signals, which includes our left turn signal, right turn signal, tail lamps, and brake lamps which will keep us DOT compliant in all states. more
