How to Install the Curt T-Connector Vehicle Wiring Harness on a 2019 Hyundai Santa Fe

Rob: Hey everybody, Rob here at etrailer.com. Today we're going to be taking a look at the CURT T-Connector vehicle wiring harness with a four-pole flat trailer connector on our 2019 Hyundai Santa Fe. Now our CURT T-Connector wiring harness is going to give us a four-pole flat trailer connector so we can have all the required lights to get down the road safely and legally. It's going to give us our taillight function, turn signals, and brake lights.Our wiring is designed to stay on the outside of the vehicle at all times, which is nice because it'll be right by our hitch whenever we need to tow. It's also going to come with a dust cap to keep all that dirt, debris, and moisture out of there and hopefully prevent any kind of corrosion on your connector. I always like to use the dust cap to secure my wiring to my hitch.

That way, it'll take all that slack and not drag the ground. But, I do recommend picking up a bracket so you have a more permanent solution, and it just gives it a nice clean look.Now as far as the installation goes, it's exactly straightforward and actually pretty easy. A lot of customers may be a little nervous when it comes to wiring because nobody wants to cut or splice anything. But that's the nice thing about our T-Connector wiring harness. There is cutting or splicing at all.

On the bottom of your Santa Fe underneath the driver side, there's actually a factory plug that our harness is just going to plug into. All we have to do is put a fuse inside the fuse holder that's attached to the harness and we're ready to go.So you can have the confidence to do it at home, let's go ahead and go through the process together. To begin our installation, we want to come to the back of our Santa Fe and we're going to come to the very back bumper on the driver side. We're going to have this plastic appearance panel on the very bottom. We need to pull that out, so we're going to grab a flat blade screwdriver.

All these push pins are going to have a little notch on the edge. You want to get your flat blade screwdriver, pop out the center section like that. We can grab the center and pry out the base. There's going to be a total of three, one at the very back and then two on the side. Now we're not going to have to worry about taking this very last one out that's on the liner here.

You just want to get these three along the edge.Now if we come underneath our Santa Fe and just move to the inside, real close to the frame rail we're going to have plastic nuts that are also holding this panel in place. You want to grab yourself an extension and a 14mm socket, and we're going to loosen those up. Now these aren't going to come completely off the panel, so you have to put a little bit of downward pressure as you're loosening it up. It's going to be a little bit hard to see, but in this indentation we're going to have another nut that's going to be up against the frame. We're going to pull this panel down and we'll set it aside.Now behind that panel, you should have a plug. It's just going to have a dummy cap on it. We want to come to the end, we'll push down on that tab here. That'll release it and we can pull the cap off. We can grab our harness now, and you want to make sure that the fuse is not in the fuse holder yet. Before I plug it in, I always like to put a little bit of dielectric grease in there. Just going to help protect the circuits and make sure moisture doesn't get in there and we don't have a buildup of corrosion. Just put a little bit in there. Then we'll take our plug, line it up, make sure it clicks into place.now we need to find a spot that we can mount our converter box. Now we got a couple different options of how we can mount it. We can use the eyelet on top, zip tie it to some existing wiring here, or we can use the double-sided tape and find a nice flat surface to stick it to. I think I'm going to use the double-sided tape and I'm going to stick it directly to the back of the bumper here. Then I'll also use a zip tie to zip tie it to this wiring in case the tape ever fails. I just do suggest that you clean off both sides of the surface you're going to be mounting it to so you don't have to worry about the tape failing because of dirt behind it. Just remove the backing off one side of our tape, put it directly on the converter box. Want to push it on there and make sure it sticks well. Then the other side of the backing. Like I said, we'll just come right up, stick it directly to the edge of the body. Then I'll come back, throw a zip tie around this wiring here so it's nice and secure and we don't have to worry about it moving.Now we just want to route our four-pole wire towards the center of our hitch, and we can tie up the excess wire behind the fascia here. Just want to make sure you leave yourself enough slack so you can get it plugged in. I'm going to go ahead and zip tie all my wiring up, and then we can get our panel back in place as well. We can just slide the dust cover over our wiring. If you don't have a bracket on your hitch, I always suggest picking up a no-drill bracket. Then that way you can permanently mount your wiring, it's a little more secure. But if you don't have a bracket, you can always just take your dust cover, loop it around the safety chain loop, and that'll keep your wiring off the ground.Then when you're putting your panel back, you just want to line up the studs with those screws, and then just push it back into place, and it'll hold itself back in. Then we take our push pins, make sure the whole push pin gets in the whole and the base goes in first. Then we'll lock it down with the center.Now the final step of our installation is going to be testing all of our circuits and make sure everything's working properly. So I went ahead and plugged in my four-pole tester. If you need one of these, you can pick it up here at etrailer.com using part number I26. As you see, when I turn on my headlights, our taillight function is working, as well as the left turn signal, the right turn signal, and our brakes. Now that we know that everything's working, that'll finish up your installation and your look at the CURT T-Connector vehicle wiring harness with a four-pole flat trailer connector on our 2019 Hyundai Santa Fe.
