How to Install the Tekonsha T-One Vehicle Wiring Harness on a 2020 Kia Telluride

Hi there Telluriders, today in our 2020 Kia Telluride, we're going to be taking a look at and showing you how to install Tekonsha's T-One four-pole flat trailer connector vehicle wiring harness. This four-pole wiring harness is going to provide you with all the necessary lighting that you'll need to keep you DOT compliant in all states. This includes your left turn signal, right turn signal, tail lamps, and brake lamps. One of the things that I like about this harness is that it has a module that's included in it, and it plugs directly into your vehicle's factory tow package connector. The module's is going to monitor all of the outputs on your four pole flat connector, and if it detects any faults, it's going to shut down that circuit. This is nice because if you do have any faults on your trailer, it's not going to cause any damage to any of the wiring on your vehicle.We'll begin our installation underneath the vehicle.

Now I have removed the spare tire, but that was just for video purposes. You won't need to at home. We're going to remove the driver's side underbody panel here. We'll use a flat blade screwdriver to go in between the slit there and pop out the center tab. You can then just pull it right out.

We're going to repeat this for the two remaining pins, and then we'll use a 15 millimeter socket to remove the two plastic nuts located in the slits here for your panel. When removing these, I recommend you pull down slightly and that will help them come off a little bit easier. We can then set our panel aside and we'll now unplug the dummy plug here on our harness, press in on the release tab, and then just pull outward. We can now take our new harness and plug it right in.We can now take the double-sided tape that comes with our kit, peel off the adhesive backing, and apply it to the back of our module. We can then peel off the adhesive backing on the other side of the double-sided tape, and then stick our module onto the side of the vehicle, and you want to hold it about 20, 25 seconds to ensure good adhesion.

We can then take our excess wiring and zip tie that up to make it nice and clean. We're using the included zip ties that come with your kit. And route our four-pole flat connector towards the center near our receiver end. As I'm routing it over, I am kind of tucking it behind some of the brackets here behind the bumper. That'll just help keep the wiring out of the way.

We'll then zip tie it to any existing wiring to make sure it's nice and clean.Over here at the center of our hitch, we can use the dust cap to secure it to our safety chain loops, and then you can use some zip ties to tie up your wiring right to your hitch. And now you can plug it in and test it out. You can either plug it into your trailer or to a tester like we have here. If you want to purchase the tester, we have them available here Make sure that you have your left turn signal, right turn signal, tail lamps, and brake lamps. With everything working properly, we're ready to hook up our trailer and hit the road. And that completes our installation of Tekonsha's T-One four-pole flat trailer connector vehicle wiring harness on your 2020 Kia Telluride..
