Hopkins Trailer Wiring Harness Installation - 2020 GMC Sierra 1500- Video
Ryan: Hey everybody, Ryan here at etrailer.com. Today on our 2020 GMC Sierra 1500 we're going to be taking a look at and showing you how to install the Hopkins 7 and 4-Pole trailer connector socket.Since the GMC Sierra actually comes with a blank dummy plug already installed on your back bumper, it's going to make putting this one in really convenient. And since it really doesn't look any different, the back of your truck is going to look pretty much the same. I really like how versatile it is since it offers us not only a four way connector, but also a seven way. That way you should hook up to multiple different trailers that have different types of wiring.So the four way connector, that's going to provide us with our turn signals, as well as our running lights, and our brake lights. The seven way connector is going to give us those same lighting signals with a few more. more
