How to Install the Tekonsha T-One Vehicle Wiring Harness on a 2022 Kia Telluride


Hi there Kia owners. Put in your 2022 Kia Telluride. We're going to be taking a look at and showing you how to install Tekonsha's 4-pole flat trailer connector vehicle wiring harness. And this is what our harness looks like when it's installed. We do have brackets available here at etrailer. I typically recommend a combination of a no-drill bracket and a 4-pole bracket.

The no-drill bracket will allow you to clamp a bracket onto your hitch. And then you can mount your 4-pole to that bracket, so you don't have to drill into your vehicle at all. To get you a nice mounting for this connector. It doesn't need to be mounted, though. It works just fine, right here.

You can see that there's not an access length where it's going to fall down. And when you're not using it, you can secure it to your hitch using the dust boot here. The dust boot keeps out dirt, debris, and moisture ensuring long lasting operation of our connection. We'll go ahead and take our dust cap off now. And we can see our four connections inside.

It's going to include our left turn signal, right turn signal, tail lamps, and brake lamps. So we'll get all the necessary lighting signals at the back of our vehicle for our trailer, keeping us DOT compliant in all states. What I like about this harness is that it has a module that's integrated into the harness, and it's custom fit for our Telluride here. So it plugs directly into the factory connector. The module will then observe all the signals that it receives from that factory connector, and it will reproduce those signals and send them out our 4-pole flat trailer connector.

What's nice about that is if the module detects any shorts or faults on our trailer, it can shut that circuit down to prevent any issues with the wiring on our vehicle. Now that we've covered some of the features of our wiring, why don't you follow along with me, and we'll show you how to get it installed. It's an extremely easy harness to install with it being custom fit for our vehicle. There's one panel we'll remove underneath here. And this is something you should probably have done in about 20 minutes at home. We'll begin our installation underneath the vehicle. Our connector for our wiring that we're going to plug into is going to be located underneath the panel, here. To remove this panel, we'll have three clips here at the bottom, we'll just pop those out with our flat-bladed screwdriver. There's a little notch and like kind of a plus shape about it. you'll see those little notches. Choose any one of them and just stick your blade in there. That'll just pop it right out. After we remove these three, we'll grab our 14 millimeter socket to remove the two plastic nuts holding the panel in place. They're up in these kind of curved areas here. And with these plastic panels, to get these removed, we're going to give it a slight downward pressure. That'll help work, walk it right down the threads. The same thing with the other one here. And then we can set this panel aside. Behind our panel here is our factory connector that we're going to plug our wiring into. So we can go ahead and remove the cap from it. It's got a cap on there. That's the release tab, you can press on that and then pull the cap off. We'll then, take our new harness here. This is our custom fit harness. It's got a connector that will plug directly into our factory connector here, making this an extremely quick and easy installation. At that point, your wiring is functional. But, we're going to go ahead and clean things up. You're going to get some zip ties in your kit, as well as some double-sided adhesive. So we can get this module mounted. We'll just open up the little bag here. And we'll get that attached. What I'd like to do before mounting the module is I like to take the 4-pole wiring here and go ahead and get this undone. That way we can kind of route it towards the center of the hitch. So that way, when we mount our module, we don't accidentally mount the module in an area where it's too far away from the center and we don't get a very good length of wire left over to get there, so. Let's get this rubber band off of there. Kind of route the wire there. Just kind of go in above the hitch and it'll come out the bottom here. Make sure we got ourselves enough length to work with, that looks like a pretty good amount. We'll go ahead and secure it to our safety chain loops using the dust cap. And so that way we know that it's gonna have the length we need to get over there. And then we can clean up over here and get this mounted. We're just going to use some double-sided adhesive to do so. You'll get double-sided adhesive in your kit right here. So we're just going to take the double sided adhesive, stick it to the back of our module. And then I'm going to get a little bit of alcohol on a rag, and we're going to clean up this area here because that's where we're going to be sticking the module. We want to make sure it's nice and clean. If we've got dirt, debris, dust, stuff like that there, the adhesive on our pad, isn't going to want to adhere to it very well. So, that's why alcohol is a really good option to get that all cleaned up. And we'll just grab our module, peel off the other side of our adhesive backing. And then we're just going to stick this right into place, where we cleaned that up. And now at this point, all that's left is just zip tying up our excess of wire that we've got here. Just kind of wrapping it up. We're going to zip tie it to a factory wire that's right here to help hold it all into place. And it's not a bad idea to get your 4-pole wire in here as well. Just to help keep everything as neat as possible. All that's left now is to install our panel back into place. So we're going to lift it up, line up those plastic nuts with the studs, they just push right on. And then, we'll put our pins back into place. And after that, we're ready to test our system out. You could either plug it into your trailer or you could plug it into a tester. We're going to be using a tester here at etrailer. And I prefer the tester method, because if you have any faults on your trailer, your system may not work properly because of shorts and things like that. And you may think, "Oh man, the issues with my wiring that I just installed," but really the issue might be with your trailer. If you use a tester, you can verify for sure that your vehicle is working properly. So when you do plug into your trailer, if you've got an issue, you know it's on that side. So here we've got our tester plugged in. You can get these here at etrailer. We want to verify we've got all our lighting signals, which includes our left turn signal, right turn signal, tail lamps, and brake lamps. With all of our signals working properly, we're ready to hook up our trailer and hit the road. And that completes our installation of the Tekonsha's 4-pole flat trailer connector vehicle wiring harness on our 2022 Kia Telluride..
