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 trunk floor coverings, rear scuff panel, and 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.
Once installation is complete, the 4-way connector will be stowed in an out-of-the-way location within your cargo area.
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.

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.Other than routing the Hot wire from the rear of the car to the battery, it was a simple installation.
Everything included in kit you need to install. My only issue was installing wiring to taillights. I found it easier to remove bumper to ease routing of those wires through grommet to taillights. With hitch installed it is only a couple clips and screws holding it on. This made it easier for me and my big hands!
Very difficult
It is exactly what I needed super fast shipping
I think the way people installing the wireing is crazy. One guy says he took off the rear bumper , to install the wires thru the large grommet. When you take off the rear light lens, there a small hole with a rubber plug, pop that out and run your wires thru it. You have to cut the wires and reconnect it.
It functions as described, but the install effort isn't worth the trouble versus directly tapping to the to harness in the trunk rather than at the tail lights. Feeding the connectors through the fender to the tail light locations goes through a circuitous route with very tight fit. Especially the left side with two connectors. Misleading instructions aggravate the problem. Forget the printed instructions which are minimal, show a much different type of car and 2 different wire configurations, neither of which matches this product's wires.
The video is not too bad, but misleading. When it shows fishing the converter harness connectors through the fender to taillight location, it shows only the very start and then just as the second connector is pulled out into the tail light location. It skips all the time getting the fish line through, and then maneuvering two connector simultaneously through a tight fit around corners.
It is far easier to just cut the wires next to the connectors then pull only the wires through. Which is what I did after trying to get the connectors through the fenders and repeatedly getting stuck. Then reattached connectors to wires with crimp connectors. The install already requires you to have a crimping tool for the power wiring.
Getting a pull line though the fender route is tedious, but once that's done it's easy to pull the wires alone though.
Video does more or less the same thing with getting a fish line through the wire passage in the bottom of the trunk without getting stuck in the existing harness then routing the power wire. It shows the power wire emerging out into an open space below the car "where the drive shaft would be." That's fine unless you have a AWD Fusion, which has that drive shaft and rear differential and and differential controls and two rear drive axles all of which affect the wire feeding through floor and the wire route in that area.
Video also has on two mistakes in order of steps. It forgets to mention removing 2 push in retainers from trim across bottom of the trunk opening before popping the trim piece off. And video shows replacing that same trim piece before replacing the trim on side of the trunk. The side trim overlaps (underlaps?) the center bottom trim piece by about an inch. That is, side fits under center. The center trim is the last thing to go back.
Video shows attaching the power wire to the battery lug clamp nut which seems a marginal solution. Fortunately my car, unlike the car in video, has an unused vertical threaded stud on the lug which appears to be intended for attaching accessory power wires. I just had to provide a 6mm nut.
Everything was good quality and works perfectly. Never having done it before, installation was quite a project. But by following directions and looking up how to dismantle the tail lights to do the wiring, I got through this project. I will tell you that the installation of the trailer hitch itself was much easier than doing the lighting wiring.
Definitely not the easiest thing to install but that's not Curt's fault, although directions could have been more specific. Installed on 2015 Ford Fusion with limited issues. Biggest were feeding the tail light connections up through the trunk and feeding the power wire from the trunk to the battery. I did it under the backseat, along the trim and through a grommet in the drivers firewall (up behind the steering wheel), not the easiest but can be done. Watch some videos first and you will be fine. Oh and make sure you have all the right equipment and tools.
Overall I am quite satisfied with this trailer wire adapter. (second one) My vehicle is a 2014 Ford Fusion. One improvement for this unit would be to install bullet connectors on the wires going up to the taillight adapters. As purchased they are very difficult to feed thru to the rear lights.
Pretty easy to install. I have a hybrid, so the battery is in the truck near the driver's side taillight. That really simplified the install. The video showed them snaking a tube up through the grommet hole. I found it easier to drop the connectors down to the ground from inside the trunk, then run a fish tape down from the taillight housing. Tape the two together then pull up and into the housing. I also did the passenger side first, so I would have as much slack as possible by moving the module all the way over to the left.
Harness works great. Hardest part was running the power wire to the front with no access to a lift. No issues after a year of use. The installation videos will walk you step by step on how to install it right.
I was impressed that you provided everything, including extra wire ties and a simple way (2-way sticky pad) to mount the controller. I was installing on a 2019 Ford Fusion Energi and there was not much space to pull the connectors through. I strongly recommend anyone doing this view the YouTube video from Uhaul. That video was very helpful.
In the install video of the trailers lights for the ford fusion 2014 he uses a black hose to run the lights to the tail lights and to run the battery wire through the engine and you don’t include one and it took me two hours to do it with my own softer hose. If you included it women like me wouldn’t have so much trouble. thank you
The installation video was a big help. Fishing the wires through those small holes behind the taillights was the most time consuming part of the whole project. Worked perfectly.
Installation instructions made the job a breeze, wire lengths provided are more than sufficient.
Nothing against the product itself but the instructions itself was not very helpful as the variant of my Fusion was a PITA to fish the plugs out to the tail lights... Next time I shall cut and splice after fishing bare wires
Great product, easy install. Just watch the install video. Put this on by myself, didn’t even need to jack up the car. Done in less than 20 minutes!
DONT KNOW HOW TO SEND A PIC THE ORDER WAS DELIVERED EALER THEN EXPECTED THAT WAS GREAT ALL PARTS IN TACKED DID NIT SEE HOW DELEVERED IT BUT IF IT WAS UPS THE BOX WAS BROKEN A LITTLE BUT IF IT WAS USP GIVE THEM A LITTLE LONGER AND IT WOULD HAVE TO BE RETAPED AND THEN SOME ALL THE THINGS I BUY AND THEY DELIVER IT LOOKS LIKE IT WENT THROUGH A WAR BUT THANKS ALL PARTS ACCOUNTED FOR GOOD JOB ON YOUR PART
It works well. I ran the power wire through the interior of the car and through the fire wall to keep it out of the weather. So the install took a while. About 3 hrs mainly figuring where to put the wire through the fire wall. I ended up going through a rubber grommet right behind the battery. Turned out perfect.
Worked fine on my 2013 Fusion for towing a 500 lb trailer cries country.
It took me a while to pass the wires through. It took me about 2.5 hours. Saved some money doing it myself though. Good deal.
So easy to install if you follow instructions. Maybe 30 minutes and I'm ready to hook my boat up and go fishing.
Perfect fit. Was not able to use the plastic cover after mounting hitch.
Product was exactly as described. Shipping was super fast and the product was worth way more than paid for. Highly recommend.
Failed in less than 3 months.

You mentioned that it failed within 3 months and I wanted to ask you a few follow up questions. Can you be more specific in how it failed? I know that you replaced it however do you still have it?

The black converter box or whatever it is called failed. The lights no longer worked. They just stayed on dim. When I bought the new kit, to save time I only swapped out the black box as all the other connections were basically the same. It is still working fine. I do not still have it.
