## Overview

The CURT 56348 Vehicle-Side Custom 4-Pin Trailer Wiring Harness offers a hassle-free, vehicle-specific solution for Hyundai Tucson owners seeking reliable trailer light connections. Featuring a plug-and-play design with no cutting or splicing, it delivers consistent power through advanced surface mount technology and protects your connection with a durable dust cover—making towing safer and simpler.

## Description

If your vehicle is not equipped with wiring for towing a trailer, CURT custom wiring is the ideal solution. A custom wiring harness -- also called a T-connector -- is a simple, plug-and-play electrical device that plugs into your automotive electric system and provides a standard, universal trailer wiring connection. This is done using two or more vehicle-specific, OEM-compatible connectors to plug into the taillight assembly, eliminating the need for cutting, splicing and soldering during installation. Custom wiring harnesses are made vehicle-specific, and while they are not available for all vehicles, they do offer one of the fastest, easiest and most secure ways to wire a vehicle for towing. This particular plug-in harness provides a 4-way flat connector socket and is designed to be a custom wiring harness to fit certain years of the Hyundai Tucson (to verify your vehicle compatibility, see application info). It comes with all necessary wiring components to establish a reliable trailer wiring connection, as well as a dust cover to keep the connector clean when not in use. You have a picture in mind of your next destination -- maybe it's the boat landing at your favorite fishing spot, maybe it's a campsite that overlooks one of nature's masterpieces, or maybe it's the next big jobsite. However, turning that picture into a reality takes more than just daydreaming. It takes a solid connection and the right amount of power. CURT custom wiring is made with some of the most sophisticated technology in the industry and is designed to install with ease, giving you a long-lasting electrical connection for your towing hitch setup.

Review: I got this for 2019 Tucson! - This is my first review with instructions since I couldn't find or support from any of the online sources for my 2019 Tucson! I got a new 2019 Tucson last year right after the Christmas day and the 2019 model was a facelifted model so the basic frame structure was the same. However, Hyundai added many more new features so this kit will not be going to fit as a direct plug and play. Although, the main connection socket was the same, you have to modify a bit to work properly. However the same sockets, that's what I was looking for!!! I contacted Curt and they didn't have any anticipated date to be available to the market for the custom wiring kit for 2019 Tucson. I'm sure it will be available sometime soon but I didn't want to wait any longer with something that I don't know. So I took a bit of risk and it worked as it should be for me! I'm not a professional or expert and I do have limited basic knowledge about the tools and circuit. That's why I didn't want to modify any wires to the Tucson side. If I screw up on the vehicle side, it would be hard to source parts and going to be expensive fix so I took the safe way. If this doesn't work, I just wasting my money on this kit and keep my basic warranty since I didn't modify anything that factory installed. But it works as it should be with minimal modifications! Like I mentioned above, I didn't want to do any modifications on Tucson's side so I figured the new wire arrangement order. It's slightly changed from last year's model. But if you have a tester, should be easy to figure them out. (Also attached new wire arrangement and the wire color diagram for you! If you don't want to wait like me!!!) For the 2019 Tucson, Hyundai put lane change assistance + cross-traffic sensors, the wire is pretty short and I didn't want to put the wire directly around the sensor, so I did add about 3' wire for the right rear taillight connector. The time that I took was about 2 hrs for the whole installation process by myself including all wire modifications. If you want to install it to 2019 Tucson without any modification to your car, I think this kit would do with minimal modification to this kit. It's doable if you have basic knowledge and tools. The last picture shows that I successfully rented a trailer from the U-haul! and worked great!!! I hope this helps for anyone who wants it now!
Review: Works great - Easy to install, works great.

### ⭐⭐⭐⭐⭐ Works great
*by G***Y on October 11, 2024*

Easy to install, works great.

### ⭐⭐⭐⭐⭐ This was not a tough install.
*by B***E on December 28, 2020*

Watch a YouTube video on how to install and also a quick one on how to remove the tail light on the car. I have a 2013 Tuscon and what i did was removed the tail lights. I skipped removing the plastic behind the rear tire. I just took a carpenters chalk line and dropped the end down the hole you will see when you remove the tail light to the ground. I hooked my wires with the end of it and pulles it up through the hole with the chalk line. After i got both sides hooked up i located the break lines that run under the drivers side and planed on using its pathways and holders for my power wire. You will notice in the area about where the drivers back seat floorboard to under the drivers seat is a plastic channel the break lines go through. Start at the end closest to the front because it is narrower. Thread your power wire through it. Its tricky to do but it can be done. Once you get it run it all the way back to the power converter. Now go back under the drivers seat and thread tge other end through the brake line mounts. I think there were 3 of them. There is an extra hole the wire can go right thru. The brake lines will go right on up to where the battery is. No problem at all. Several people said the wires were not long enough. Maybe the company read those reviews and made changes because i had plenty. I had about 4 feet left over on the power wire. The pigtail wire had a plenty extra and at the tail lights there was enough. I really liked how easy it was to install. The power wire actually was thicker than i expected it to be. Great product!
