Trailer Wiring Harness Installation - 2016 Kia Sedona

How to Install a Trailer Wiring Harness on a 2016 Kia Sedona

Today on our 2016 Kia Sedona, we'll be taking a look at and installing the Curt T-Connector Vehicle Wiring Harness with 4-Pole Flat Trailer Connector, part number C56151. The first thing we're going to do on our vehicle is locate the manufacturer tow package, and that's going to be underneath the driver's side rear section, right behind that rear fender wall on the driver's side. It's going to be right here. You're going to have two plugs that are going to have caps over the top of them and we're going to need to remove those caps. Go ahead and press the tabs together and pull out. You're going to have the tab here on the side that you just need to press in so you can remove it. We'll set it off to the side, since it won't be going back on.

Up here on top, we're going to remove this one. This tab is actually going to be around the back side. Feel for it with your finger. It will be right in the center, right here. Here's going to be our wiring harness, with those two factory connectors that are going to connect to our factory harness. We're also going to have a fuse that we're going to need to place in.

Take the 10-amp fuse, place it in, press firmly and then put the cover over the top. If you want, you can take one of those included zip ties, run it through the hole and secure that to make sure it doesn't come undone. Let's do that before we plug it in. Take your T-connector harness and plug it in to the tabs that we removed the cover from. Press it in till it clicks in place. Once it's in all the way, go ahead and move to the next one.

Now we'll go ahead and run our wires back behind our bumper and underneath. That way, those wires won't be exposed on the back side of the hitch, and kind of look gaudy 00:01:57 underneath the back side. We'll go ahead and remove the four plastic push-tabs here on the back of the vehicle, two on either side of the receiver tube. Go ahead and take a flat-blade screwdriver, stick it in, pop out the center and pull them out. We'll be able to pull that down now and have access to reach our hand back behind to zip tie up that wire and get it out of the way.

Use the zip ties that are provided in the kit, and there's going to be multiple attachment points underneath to get these wires tucked up in. That way we can get rid of that fuse, the converter and all that back behind, and just have our wires and our 4-pole connection coming down right behind the back side of the hitch where we can anchor it up. Now we'll go ahead and pull down on this so you can see back behind where we anchored up, put the 4-pole wire coming down, and then securing it here to the old emergency tow hook on the back of the vehicle. Go ahead and pop those four pushpins back into place, making sure that you have the center popped out, and you just slide them up into the hole. Push the center in and lock them in. We'll then put our cover over the top so we can protect our 4-pole in when we don't have it in use, since it's going to be underneath the back of the vehicle. Slide it over and check on the end to make sure that you have it on the right way. If you need to flip it around, you can. And then press it on. Let me go ahead and test out our wiring, by connecting our ground to the ground stud. We'll test out our brown wires first, which will be our running lights. Should get a constant signal. Now we'll go ahead and test out our left turn signal, the yellow wire. Then our right turn signal, the green wire. Then brake, which will be both the green and the yellow. Works good. Let's go ahead and tighten this up on the back, to make sure it doesn't fall, and we're ready to hit the road. And that will do it for our review and installation of the Curt T-Connector Vehicle Wiring Harness with 4-Pole Flat Trailer Connector, part number C56151, on our 2016 Kia Sedona.
