How to Install the Curt Powered Tail Light Converter on a 2019 Kia Sorento

Today on our 2019 Kia Sorento, we're going to be taking a look at and showing you how to install the Curt powered taillight converter with four-pole flat trailer connector. All right, this is what it's going to look like installed. This is going to give us all of our necessary lighting functions for our trailer: Stop, turn signals, and running lights. It puts out 5 amps for our turn signals and brake lights, and it puts out 7.5 amps for our running lights.To begin our install, we're going to need to remove the tail lights. So first, we open up our hatch, and there's actually a panel right here on each side are exactly the same. Going to remove these panels to gain access to the nuts that are holding the tail lights on.

So this is the panel. As you can see, there's two little notches in it, and with those notches, we can take our flat-blade screwdriver. Put it in there, just gently pry up, and set it to the side, and do that exact same thing to the other side of the car.All right. Now, we need to remove these two black nuts. We're going to do that with a 10-millimeter socket, and do the exact same thing to the other side.

All right, now you don't have to, but I like to put a towel and some tape right underneath the tail light just to protect the paint, because we'll be working in this area. Now, with the two nuts removed from the back of the tail light, we can now pull the tail light out. Now, there is some snips back here, and they're kind of tricky. So, what I did was I took a flat trim panel tool and actually lightly pried right here against the tail light. While making a shaking motion, I was able to pop it out.Now, with the tail light hanging like this, we can remove it.

That way, we can test our wires. To remove it there's simply one little clip you push down. Pull out like so and set this light off to the side. All right, now, with both lights out of the way, we went ahead and tested the light's wiring to figure out which ones we're going to need to connect to. What we found was here on the driver's side, the green and orange wire, this will be for your brake lights.

The green and black wire, that will be for your running lights or also known as your tail lights. And this all gray wire, this will be for your left-turn signal.Now, here on the passenger's side, the only wire that we're going to need is this white and black wire. Now that'll be for the right-hand turn signal. All right, so here we have our new harness, and I just want to show you guys which of these wires will hook up to our factory wires. The brown wire and our new harness, this will actually go to the black and green wire, and as I said earlier, that will control our running or tail lights. The red wire, that will actually go to the orange and green wire, and that will control our brake lights. The yellow wire, that will get connected to the solid gray wire, and that'll control our left-turn signal.Now, this white wire here that has a ring terminal on the end, that will just be a ground, so we'll find a good spot on a metal surface to ground it to. Now, the kit comes with these style connectors, which we're not going to be using these. We're actually going to be using these heat shrink butt connectors because they're a little bit better for outdoor use. Now, if you need some of these, you can find some on Now to be able to mount our box in the proper secure location, we actually had to extend the wiring so that it will reach it. So, if you need some extra wiring, you can pick some up on happens to be color coordinated. So what we did, we went ahead and tapped in our appropriate wire into the taillight harness, ran it down through behind the bumper into a pocket and that's where we're going to hook it up to our box. We're going to need to gain access to this panel on the driver's side rear behind the driver's side rear tire to complete our wiring. So to remove it, there's going to be four fasteners, two up here and two down here. These ones up here, you can loosen them with a 14-millimeter socket. However, if you take these off first, we can normally just pull down and these will break free.So to get these, you get a flat-blade screwdriver and op it down and use your hand to pull it out all the way. You can grab the panel, remove it and set it to the side for now. Now, with our panel out of the way, we can reach up and grab our wires that we extended and drop these down. Just set them out of the way. From there, we can take our box and the supplied Tek screw and mount it. Now, we're going to go ahead and mount it about right here, and that'll make it really easy to work with, but keep it nice and safe and out of the way at the same time.Then from here, we can cut our extended wires to the appropriate length and connect them to our box. Now, with all of our electrical connections made, we can use a heat gun to activate our heat shrink. Now we can take our white wire with the ring terminal on it and ground it. Now, we want to put it on a spot that's solid, clean metal. That way, it gets a good ground connection. All right, now, I went ahead and ran our green wire from the box over to the passenger's side. I did that by using some zip ties to secure it up along this bumper support, and I made the connection right here.Now, this is the wire that we extended down from the passenger's side of the vehicle just like we did on the driver's side. All right, at this point we can run our four-pole wiring. Typically, you would have your head shear. In this case, we don't, but for demonstration purposes, I'll show you how you would do it. You could run it up, and your hitch too would normally sit about right here. You can just zip tie it to it and then either use your mounting plate that you have to mount your four-pole or just take your dust cap and wrap it around your safety chain loop and let it hang that way.Went ahead and ran our black power wire up to the front of the vehicle. We made the connection to our box. The black wire that comes out of our box with a heat shrink butt connector, and came up and zip tied it right here. Came across and zip tied it to the top of the subframe. Now you can run it any which way you'd like. Just be sure to avoid any hot or moving parts. But the way I did it, I came across on top of the subframe, and it actually came down right through there, and zip tied it to that line. Then I just came along the side of the fuel tank and under this panel.Now this panel, you can remove three 10-millimeter nuts. Now, actually, allow this panel to pull down, makes it a little easier. Here, you can see the wire. Then I brought it right up along our brake lines here and up into the engine compartment. So here's our power wire from underneath the car up into the engine bay. To get this up easier, we actually used a pull wire, so we ran the wire, our pull wire, down through the engine bay and connected the end of our power wire to it with some electrical tape. That way, we just pulled it off, and here we have the end of our wire.So now we need to hook this to the battery. The first thing that we're going to do is actually remove this ram-air intakes. That way, we have a little more access. Let's do that. You simply just pull back. Let's stop and pull up on these tabs, and it pops right up and just set that off to the side. So we need to connect the black power wire to our fuse holder, which we'll then get a ring terminal on one end and connect to a positive battery terminal like so. Then what we'll actually do is cut a small opening in the ring terminal itself because these factory battery terminals, the nut isn't intended to be removed completely, so it'll mess up the threads if you remove it all away.So by doing this, we can actually just loosen the nut, slide this underneath, and then tighten it back down. Grab one of our supplied butt connectors. Now, we can connect our main black power wire to our yellow fuse holder. Pop that in the butt connector and get it crimped on. The power wire hooked up, we'll go ahead and open up our fuse holder and put in our supplied fuse. Just for a little extra protection, I went ahead and wrapped up our connection here with some electrical tape and reinstall our air intake. That's simply just pushes back in to the air filter box.Now that we're done with everything underneath the car, we can go ahead and reinstall the panel that we took off earlier the same way that we removed it. All right, now, we can reinstall our tail lights. So we'll simply take our plug, push it into place. You'll hear a clip. Then we can carefully realign the holes and reinstall our 10-millimeter nuts on the back side. All right, now, with everything reinstalled, you can go ahead and test it to make sure everything works properly.So here we have it hooked up to a tester, and I'll go ahead and turn on my left blinker. All right, blinker, my brake lights, and my running lights. That'll do it for our look at and installation of the Curt powered taillight converter with a four-pole flat trailer connector on our 2019 Kia Sorento.
