Hello neighbors, it's Brad here at Etrailer, and today we're taking a look at and installing the Tekonsha T-One Trailer wiring harness on a 2023 Hyundai Santa Fe. 4-pole trailer wiring is essential when hooking up to a trailer or some of your accessories that may have light functions. And this is gonna allow you to get your running lights, your turn signals, as well as your brake lights, to the lights on your trailer and that way you stay safe and legal. And this one's super easy because it has the tow package, so it's really just one plug, routing some wires, make sure that they're secure, and that's it. It's also module protected, so you have nothing to worry about. If you have some maybe not so great wiring on your trailer and you get backfeed, it's gonna be protected from destroying any of the electronics on your vehicle. Gonna get this installed super easy. This is gonna be about maybe 5 to 10 minutes. You can definitely do it in your driveway or your garage, and you'll be ready to use your trailer wiring in no time. So I'll walk you through the steps to make sure you get yours installed. To begin our installation, we're gonna be underneath the vehicle on our driver's side, and there's this plastic panel and we're gonna need to remove that because that's where our plug lives. We'll start by removing our plastic push pins. There's gonna be three of 'em along the edge, and there's little slots along there to allow you to get a trim panel tool or even a flathead screwdriver in. So just separate that top button section from the bottom and it should come out fairly easily. And looking vertical, you'll see kind of in this indent, there's gonna be a plastic nut that goes on a thread. There's also one that's tucked back behind that, and these are pretty easy to get off. So I'm just gonna use a 14 millimeter socket and just by hand I should be able to get this to lower. Sometimes it helps, too, to kind of pull down a little bit to give it pressure. That way it threads off that plastic nice and easy. And keep this handy, 'cause we're gonna be reinstalling this pretty shortly. Now we see this plug, it's got a dummy cap here on it and we're gonna go ahead and remove that because that's where we're gonna be plugging in our 4-pole wiring. So now we'll just take our plug in and plug it into that factory tow plug there. And then I'm gonna just route my 4-pole over to where we're gonna mount this up. Now as far as mounting this, there's a few different options. You can pick up a 4-pole bracket, which is gonna make it nice and clean and kind of keep this in place. But you can also use your dust cap to just loop this around the safety chain loops on the hitch. It's kind of up to you, either way it works well. But I'll go ahead get this routed up, and show you how it looks. Now I did use a bracket that's sold separately to mount this up and I like these. It really makes it look clean and it's nice and easy to plug in, 'cause it's solid here. The Draw-Tite hitch does come with that tab, but again, not to worry, you can get a bracket here that's gonna mount up with any hitch really. So from here, I just kind of routed this on the backside of the hitch and just following this, I routed it up and over. There's a hole here that I was able to zip tie this up. Now the main thing is, we wanna make sure that that plastic cover can go back up, and we do have quite a bit of extra wire here. So what we'll do, there's a few different options, as far as mounting your module up. You can use a self-tapping screw and put that in any of kind of the metal places here. That's just gonna hold that in. There's also double-sided tape that you can use to stick this on. You could also zip tie this up. It's kind of up to you, but you wanna make sure that this isn't rattling around while driving. So make sure it's nice and secure. And the rest of the wires I'm gonna clean up with some zip ties and I'll show you how it looks. So I've gone ahead and knotted up our module on our excess wire by just zip tying it to some of the factory wire loom. And that's gonna hold this in place for the lifespan of your trailer wiring. So we're gonna go ahead and check to make sure our wiring's working before getting our plastic panel put back up. We'll be checking our wiring with a 4-pole tester.
