Hooking up trailer wiring can be messy, but this harness keeps things simple. The Curt T-Connector plugs directly into the tail light connectors, so there’s no cutting or splicing wires. The plug-and-lead design hides neatly behind trim panels, giving a clean install that looks factory once it’s done.
Once connected, the built-in 4-pole flat connector powers your trailer’s running lights, turn signals, and brake lights. It’s the standard setup for small and mid-size trailers and works with add-on kits like the ETBC7 if you ever need a 7-way connection for trailer brakes or 12V power later on.
Modern vehicles use sensitive electronics, and direct splicing can cause problems. This harness includes a powered converter that isolates the trailer circuit from the vehicle’s wiring, helping prevent overloads or faults. It’s designed for vehicles without a factory tow package and keeps everything working safely and smoothly.
LED lighting is becoming standard on newer trailers, and this harness is built to handle it. It’s fully compatible with LED taillights, and when grounded properly to a clean metal surface, it delivers steady performance even when headlights or running lights are on. That means no flickering lights or weak signals—just consistent power every time you tow.

Good product, good price, worked as expected. Installation directions were clear and detailed; actual install was more difficult than expected, took 3.5 hours. Product works great and worth the effort.
The kit solves all issues with modern car. Long as you order the one you need.
This is my second C56272. No slicing all pluge and play.
Running the main power wire fro battery is a bit time consuming but not that hard.
Year model changes but not a big deal, slight modification to a shield on exhaust. Great instructions and simple to install. Will buy again.
Seems they could have plugged into factory harness at the bottom of the vehicle instead of taking half the car apart.
It was the easiest wire installation I have ever done, well worth the money !
Does the job well. Kind of hard to feed wiring harness up to tail light but just take your time and all will work out.
Excellent fast service , wire harness works great , have ford edge sel
Product came very quickly. Easy to install and directions where clear and precise. Not my first etailer purchase, they have quality products and friendly customer service.
Everything just plugs into your vehicle and video was a great help.
It has worked out well.We only got to camp 3 times last year, so will hope to use more this year. My Wifes son installs hitches and said it is a good one!
Item was spot on, it was tough to fish the wires to the light as it is a tight squeeze and it was a two person job. Not the fault of the produce, Ford engineering.
Realistic installation time is 2 hrs and I am not a novice.
Worked well on our 2018 Ford Edge SEL. Be sure to properly ground all your lights by scraping off the paint first.
Easy installation. Reaching for the fish wires is the most difficult task. It helps to feel for the wire. Then pass the bolt through the hole by hand rather than letting the wire pull it through.
Nice wiring harness that worked perfectly after installation. The crimp connectors that came with the kit were not heat shrink as they were supposed to be. An easy install.
Fast shipping, excellent customer service.
We just recently replaced our 2013 Ford Edge with a 2016 Ford Edge, we had used a Curt T Connector trailer tow wiring harness for the last 3 years without any issue whatsoever thus when needing a wiring harness for the 2016 Edge in order to tow our pontoon it was a no brainer, we ordered the Curt!
Overall this wiring harness was very easy to install and had good instructions provided too. I found it easier to run the main power wire inside my vehicle under the carpet & trim to the battery vs underneath the vehicle as the instructions suggested. The only item I had an issue with was the foam tape used to mount the power module, was bad and had been dried out. So I had to secure it with my own tape.
Installed and works great. The photos in the installation instructions leave a bit to be desired since several times I found myself trying to figure out the orientation of the photo to know what i was looking at. But once figured that out, it went relatively straight forward. The routing of the line up to the battery on a 2017 Ford Edge SEL is a bit of a puzzle. I was able to remove some of the under trim under the driver seat and route through there, then up the back side of the driver front wheel well using a wire to fish the cable through a small opening in the the top of the wheel well that is slightly behind the battery in the engine compartment. If you look up into the wheel well at the spring top, you'll see the part of opening - use flashlight to see light coming through from battery side. Wire should pass across that opening and down the backside of the wheel well trim.
I installed this wiring harness on my 2015 Ford Edge and it works as designed with all connections to my trailer. The installation was completed after some difficulty in getting the wiring up through the very small space under the tail light assembly from below. I did have to remove the vehicle's connection to the tail light and then mate the trailer connection separately before replacing the taillight assembly. There was not enough extra room between the taillight assembly and the car body panel to remount with all the extra connection plug assemblies. It is well designed and works but not a real easy installation unless you have experience with one previously.
No problems, works as it should.

A little time consuming to do this. Since the trailers are LED lighting, we pulled power from the rear 12 volt port instead of running a heavy wire all the way up front. LED works fine with a smaller wire.
Hitch looks great on my 2016 edge tucks away nicely and all you see is the actual receiver. Had it installed by my mecchanics as they have a lift the only complaint they had was with the wiring an having out thru the hatch all the time so they decided to mount the four way outside to the actual receiver.
Very pleased with this product. The package arrived quickly. The installation of this trailer wire harness was a breeze. I would recommend etrailer.com and this product over and over again.
