Quickly and easily install a 4-way trailer connector on your vehicle with this custom harness. T-connector plugs directly into existing wiring. Powered converter reduces strain on wiring system and is made using SMT to ensure superior performance.

Installation
This custom-fit T-connector plugs into your vehicle's wiring harness, which is located behind the driver's-side and passenger's-side tail lights. You will have to remove the tail light assemblies to access this harness. Once you've plugged in the T-connector, run the hot lead up to your car battery. Connect the lead to the included fuse holder, and then connect the fuse holder to the positive terminal on your battery.
It is recommended that you use a small amount of grease on all electrical connections - the plugs on your automobile and the 4-pole connector itself - to help prevent corrosion.
A tail light converter is built into this T-connector. This converter is a circuit-protected, battery-powered unit that bypasses the electrical routes that are used by a basic wiring harness. As a result, there is virtually no draw on your tail light circuits.
Because most trailers run on a two-wire system - wherein the brake and turn signals are carried on one wire - the separate brake and turn signals from your vehicle's three-wire system need to be combined so they are compatible with the wiring system of the trailer. This converter combines the brake and turn signal functions of your automobile so that they run on one wire to properly activate your trailer's tail lights. Note: This will not affect how the tail lights on your vehicle operate.
Curt builds each tail light converter using surface-mount technology (SMT). This method of construction involves soldering electronic components directly to the surface of a printed circuit board. SMT eliminates the need for leads, which are used in older through-hole technology. The result is a circuit board that is smaller yet provides more routing area and that offers superior performance, reliability and durability.
Circuit boards constructed using SMT have been shown to perform better under rough conditions with excessive vibration than those made using the through-hole method. And where would vibration be more likely to occur than in towing applications? Curt converters also produce less heat, leading to increased durability and longer life. In addition, lower levels of resistance ensure better performance, especially for parts that operate at higher frequencies.
Each Curt circuit board is made using high-quality components that are pieced together in the most technologically savvy fashion, leading to greater predictability and reliability in functioning.

Easy install if you follow along with the video. Lots of crawling around under the car if you don't have a lift, but nothing particularly difficult, just awkward. I saw others complain about the short wires on the driver's side tail light connector but I didn't think it was bad. Also comes with plenty of zip ties if you route the wire the way they do in the installation video, but if you don't loosen the panel to tuck it in with the main wiring harness I could see how you might need more.
Wiring harness fit was excellent. I watched the installation video you provided, very helpful.
All good great product great timing on shipping
Easy to follow instructions, quality materials and everything included .
Direct fit, plug and play. Wiring correct length. Great product.
It was a great fit Thanks
Excellent service, Something that got my attention is how great you communicate with me about the status of the order.
Product seems to be a great quality.
Thanks
Aftermarket wiring harnesses can be frustrating. I don’t enjoy mechanic work but I removed taillights and ran wire according to the instructions. After repairing a bad connection, everything worked. Then, my lights began to short out and malfunction on a trip. It turns out that the main wire going to the plug wore through and was touching metal. I ordered another identical kit but placed the wire in plastic automotive conduit before routing it underneath my vehicle. It’s been great ever since. Spend the extra time and money to do it right.
Overall not to bad, but not like in the youube video. The wires are to short on the passenger side of the car. When you plug in to wires at the tail light the wires that go to the junction box are about 18" to short. There is no way to mount the box on the frame like they show in the video. I just left it inside below the light fixture dangling, hopefully it will work over a period of time. I guess I could have spiced extensions on the wires but for what you pay for this light kit, it seems they are a little chinsey on the wire length. Plenty of green wire going over to the passenger side tail light. At least everything fit!
So easy to install! The wiring harnesses interfaced perfectly with the car lights for a super simple connection. Plenty of extra length to allow you to position the connectors however you needed.
The wiring kit for my 2017 Hyundai Tuscon, that was very easy to install. I also ordered the hitch from here, bolted it on by myself, the whole thing didn't take long at all.
Best site I’ve found for trailer hitches. Videos are very helpful. Hitch and wiring install was straightforward. No issues.
Overall the product does what it is desgined to do however 2 tips would be the wire to the drivers side light needs to be atleast 1ft longer and you should probably mount the box to the frame the double sided tape wasn't enough. But in order to do that you need the drivers side wire to be longer otherwise its up in the body of the car. But otherwise works as planned.
This is the third trailer wiring harness I have bought from e-trailer...Installed fine and works perfect....
Wiring Harness was very easy and quick to install and after a year on the vehicle there have been no issues. Product did arrive fairly quickly also. Seems to hold up well with salty conditions of our winter too
I got it to work... wire lengths weren’t optimal for a 2016 Tucson. The harness for the drivers side was a bit short forcing me to mount the controller in an awkward place.
Simple installation!
All the connectors fit together as intended.
It's been installed for over a year without any issues.
The drivers side was made way too short. The power converter black box was up inside the fender area without any way to fasten it to vehicle. On another day, I will probably end up cutting the harness and extending the wiring somewhere between 6-10 inches at least.
Little difficulty running power wire. Wish it was a little more plug and play. However worked very well once installed
Fit like a glove, very easy to install and looks great! Solid and made to last as long as I do. Nothing was out of line and needed no alignment for all bolts to go in. Again great hitch!
Everything was included that was needed for the install. For some reason my vehicle needs a wire that runs from the rear of the car all the way up to the positive side of the battery terminal under the hood, which makes it a separate circuit with its own fuse. By removing the lower black plastic molding under the doors the wire can be neatly tucked inside for most of the way.
works great.
Directions were a little confusing but overall not bad. Not the easiest hookup but was on a new 2016 hyundai tuscon. I would recommend this wire harness again especially if someone has some knowledge of cars. Not for the guy who cant change his own oil or air filter, it would be too complicated.
Went on quick and easy. wireing harness worked out good too
Awesome product wish it had a little bit of more slack on cable running to tail lights but away from that easy to install and completely hide away,can't wait to hook up my little travel trailer to it
This company is great! We got our wiring harness in record time. Very satisfied with the service and the product.
