Best Towing Hitch Wiring of 2025

"I just finished installing this and it fits perfectly in my 2016 Subaru Outback 3.6R Limited. I purchased an ECO Hitch from Tork Lift Central, and while it was almost twice as expensive on their site, I found it for less here. The installation was straightforward, but finding the plug and making the connection took some effort since most online videos skip that part. I followed advice from others about removing the cargo tie down point to access the plug, which helped a lot. Overall, I recommend this kit; it seems well made!"

"I found the installation to be extremely easy, taking just a few minutes! The ground wire took me about 10 minutes to figure out, but it was no big deal with a drill. The Curt harness connection was perfect; everything worked right out of the box!"

"After getting a new trailer, I needed lights and was pleasantly surprised by how easy it was to install this wiring harness. I had it hooked up in minutes with no issues at all. The build quality is excellent; it’s just what I needed!"

"I had a broken cover on my cable connector, so I bought this to replace it. Installation was a breeze, and it works great!"

"For my 2018 Nissan Titan, I found that while Amazon said it wouldn't fit, it fit perfectly and was easy to install. I decided against using the L-bracket because it looked cheap, so I drilled a hole in the bumper next to the license plate for a much cleaner look."

"I recently upgraded my trailer hitch on my 2002 Silverado. The new hitch lacked a mounting spot for the trailer wiring plug, so I relocated mine. This trailer socket was perfect for the modification. Just be cautious with the thick bumper when drilling, but the final installation looks clean and protected."

“I found the installation to be very simple and hassle-free. All I had to do was remove the factory connection cover, and then everything went smoothly. I added Dielectric grease to ensure a solid connection. The kit had all the connectors I needed and even included plenty of zip ties for a neat setup.”

“The product arrived on time, and it fit my vehicle perfectly. The installation was straightforward and took no time at all.”

“Despite not being listed for my vehicle, I knew the part number was right. This was a fantastic purchase; it was way easier than splicing wires, and the installation took just seconds.”

“I found the installation to be really easy. I used a YouTube video for guidance and had no problems, although I did need to be comfortable piercing the steel for the ground since my Odyssey didn’t have a spare screw hole.”

“The running lights worked perfectly after installation, but I faced issues with the left and right indicators. I checked everything and it seemed okay, but the black box was outputting low voltage. After a replacement, everything worked fine.”

“I was overall satisfied with the installation. The instructions were straightforward and easy to follow, and I appreciated the included zip ties for keeping the wires tidy.”

"I found the installation relatively easy, although the provided instructions were not very helpful. I relied on a YouTube video, which guided me through each step. Despite having no prior wiring experience, the setup was manageable with the tutorial. The harness works well and meets my expectations for functionality."

"I loved how simple the installation was, and the fact that it was plug and play made it even better. My son and I installed it in less than an hour, and the instructions were pretty good too."

"I purchased this to replace another aftermarket trailer light harness for my 2019 Jeep Wrangler. It resolved the issue I had with the Canbus system. The box effectively fools the system into recognizing the draw of an incandescent light bulb, allowing full voltage to pass through to my trailer lights."

“I found the installation to be very straightforward, and I had no issues getting everything to work. The quality of the wiring is also impressive.”

“Installing this in my 2022 RAV4 Prime SE was a bit of a challenge, but once I got the trim off, it became much easier. I recommend checking out a YouTube video for guidance.”

“I was initially concerned when I received an opened box, but thankfully, all parts were included. The installation took me two hours, and I appreciate the option to keep the harness protected.”

"I found this item worked beautifully to replace my seven pin receptacle, allowing me to plug back into it. It gives off a four prong lead for adapting camper shell wiring for my brake light, and it just works amazing without the need to splice!"

"Using this adapter was great. It's a bit bulky, but I managed to use zip ties to secure all the extra wire. Adding lights was super simple; I just wired my LEDs into a 4-way flat trailer plug and plugged it into the adapter, hiding all the wires behind the bumper."

"I bought this harness to connect a rear light bar. It was truly plug and play, just as I expected from Curt. I rated the sheerness a one star because the wires and other components are completely opaque, which I found amusing!"

"I installed it and it works fine. There's no extra length to the wires, so the box needs to be behind the left backup light and the battery vent grommet served nicely for the power. I'm glad I saved $30."

"I gave the trailer wiring harness to my mechanic. He installed it and it works perfectly."

"Unlike other reviews, I found that this CURT 56474 works just fine for a Kia Sorento. The installation was straightforward, but I wish they had provided better instructions regarding the wire routing. Overall, I'm satisfied but deducted a star for that reason."

"I've found it pretty good and easy to install. I've had it for a couple of years now and it still works no problem!"

"The installation was basic and easy; the only tricky part was the battery wire, but I still recommend it!"

"I received a faulty item and they refused to replace it. I would advise others to avoid this seller!"

"I was thrilled that it was a direct fit for my factory setup. It made installation so easy, and now I have an extra 4 wire connection without needing an adapter in my 3/4 ton Ram. I'm planning to repurpose the old one for a trailer jack with a 20v battery. This way, I won’t have to back the truck up just to adjust the jack!"

"I've always been impressed with Hopkins towing products. The quality is consistently high, and the instructions are always clear and straightforward. I would definitely recommend this product and this company!"

"My 2005 Dodge Dakota came equipped with the factory package. When I found the original 7 pin trailer connector damaged, this new connector fit right into the factory harness. I did have to do some file work on the bracket, but after creating a new slot, it fit perfectly as the original did!"
