Ryan: Hey everybody, Ryan here at etrailer. Today, on our 2018 GMC Terrain, we're going to be taking a look at and showing you how to install the Curt vehicle wiring harness. So, these Terrains are really good all around versatile SUVs and that's why people use them for a little bit of everything. And the trailer wiring, what that's going to allow you to do is hook up to your trailer, illuminate the lights to not only be safe and legal, but allow other motorists around you to know your intentions as you're going down the road. And one thing people don't really think about is that some accessories, particularly cargo carriers, for example, actually have lights on them and can be lit up at night as well.

Rob: Hey everybody, it's Rob here at etrailer.com. And today, we're taking a look at the Curt Trailer Wiring Harness on our 2017 GMC Terrain. Now, our Curt Harness is to provide us with a four pole flat trailer connector, so we have all the required lights to get down the road when we're pulling a trailer, like our taillights, our turn signals, and our stoplights. Now it's nice the fact that they give us a dust cover so we can keep all that dirt, debris, and everything else out of the connector. But, our wiring is only going to be on the outside of the vehicle when we're using it. When we're not using it, it's actually going to store on the inside. more

You simply plug in your four pole connector from your vehicle to your trailer, and it'll now provide all the necessary lighting, which includes your left turn signal, right turn signal, tail lamps and break lamps.Since this harness plugs right into your factory tow package, it acts as an adapter allowing you to get that four pole connection out at the back of your vehicle. Since you're using your factory tow package connector, all the necessary circuit protection is built into your vehicle for your towing circuits. This way, if you have a fault on your trailer, instead of it affecting any of the turn signals that you may have at the back of your vehicle, it will open the fuses for your tow package in your vehicle, which won't affect the lighting on the back of the vehicle.There's an included dust cap to keep out any dirt and debris, to ensure that you have a long lasting four pole connection. Additionally you can use this dust cap to keep the harness up and out of the way when not in use, by hooking it onto your hitches safety chain loop.Included in your box you'll receive your factory tow harness adapter connector as well as a bag with some zip ties and relays. more
