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.
Once installation is complete, the 4-way connector will be stowed in an out-of-the-way location within your trunk.
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.
Powered Tail Light Converter with Surface-Mount Technology
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.
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.

Bolting on the hitch took about 15min and was easy to do with the bolts provided and after watching the quick video on installing it.
Wiring it up on the other hand took a while. The instructions that came with the electrical was easy to follow and super helpful...finding a path for the wires underneath the car from the battery back to the hitch is what took the longest.

Box was half torn apart with no packaging in sight. Disgraceful. The wiring package was clear taped together and I hope it will work with my vehicle for plug and play as its years stop at 2017 and mine is a 2019. The year manufacturer date on the product is 5/19/2022 as there is dust all over it. Just not satisfied but I guess that what it is.

It is easy to install
by: Barbara 10/19/2019
We purchased this product for the second time after the first one shorted out due to moisture getting in my vehicle tail lights. Fortunately, our son-in-law is an automobile technician and is gracious enough to install the wiring kit as I'm sure neither my husband nor I would be able to manage it. Once installed, it has worked reliably with our 8' utility trailer.

The Curt wiring harness is still functioning a year after purchase and months of sitting idle.
by: Donald02/06/2022
I would not buy this wiring harness again. It is not worth the additional work to run a dedicated power wire. Go with the plug and play model.

The powered tail light converter connects directly to the battery to avoid overloading the vehicles electrical system. We do have a great FAQ that provides ideas on ways to route the power wire. There is non powered harness for the 2019 Ford Flex. It is part # 118472.
by: James04/04/2022
Very complete kit. Fairly easy to route. would be great if Curt included the upgraded heat shrink connectors as shown in etrailer's install video. Luckily I had some extra heat shrink on hand. I also used some split loom to further protect the wiring, especially in areas where it routed around a sharp corner and of course larger zip ties due to the increased size of the split loom.

The Curt wiring harness is exactly as advertised and undoubted a good product seeing that it is from Curt Manufacturing. What impresses me the most with this purchase was the communication and quick shipment. I ordered on a Sunday afternoon, used economy shipping and received on Thursday morning. In between getting shipping updates and notification of shipment. Can't do better than that! Therefore I will use etrailer.com for future needs and definitely recommend to others. Thank you etrailer!
by: Wayne B.02/25/2014
It took about an hour and a half to install the factory hitch and this t connector kit. Definitely worth the extra work to run the wire to the battery,better safe than sorry. Good quality kit and shipped fast!!!!

2014 Ford Flex
The only thing that was unclear during the installation was which side the "Y" connectors needed to go. Looking at the diagram, in relation to the vehicle, I made a guess which turned out to be correct. It would have been nice to have them labeled as "driver side" and "passenger side", or something like that to remove the guess work.
by: Jeff B.03/19/2013
Works excellent but it didn't come with any installation instructions. I had a bear of a time routing the wiring. Just take your time, plug into the taillights first, then mount the converter box. The rest will fall into place after that.

2017 Ford Flex
Purchasing process from etrailer was easy, shipping was very prompt, wiring installation was not difficult. Only disappointment was the lack of a solid support for final connector.

Ford Flex
Fast shipping, clear instructions. Tough install on Ford Flex only because few components underneath to zip tie power lead to. I used rear climate control tubing. No way to know yet whether heat cycles will affect wiring. Once installed, has worked perfectly so far.

2010 Ford Flex
SUPER easy to install. Pay attention and it'll be a cake walk. I say pay attention because I installed it backwards (the left and right turn signals were opposite the car). Other than that, clear directions and all supplies needed unless you modify it like I did in a few spots.

See what our Experts say about this CURT Custom Fit Vehicle Wiring
- Comparing the Curt # 56343 and the # 56063 for 2016 Ford Flex SELThe Curt T-Connector Vehicle Wiring Harness with 4-Pole Flat Trailer Connector # C56343 is replacing the Curt C56063 which was also a fit for your vehicle. This replacement is to include newer models but it won't effect your vehicle. I recommend going with the less expensive of the two because both are a confirmed fit for your 2016 Ford Flex SEL
view full answer... - Will Curt Trailer Wiring Harness C56343 Fit a 2016 Ford Flex with LED Tail LightsCurt trailer wiring harness # C56343 will fit your 2016 Ford Flex with LED tail lights. I have linked a video that covers the features of this harness and linked the instructions for you.
view full answer... - Installing the Curt T-Connector Vehicle Wiring Harness # C56343 on 2010 Ford Flex SEWhen it comes to installing the Curt T-Connector Vehicle Wiring Harness, # C56343, on your 2010 Ford Flex SE, you will adhere the powered converter box to the frame of the car in the open cavity below the driver's side taillight.
view full answer... - Routing The Power Wire To The Vehicle Battery For A Trailer Wiring HarnessAbsolutely. The Curt T-Connector Vehicle Wiring Harness with 4-Pole Flat Trailer Connector # C56343 like many other wiring harnesses requires the power line directly from the battery to power the module and to protect your vehicle wiring from overload. Many times that wire is included in the kit, but that doesn't always make routing that wire easily understood. I have attached the document that we put together to assist installers with routing that power cable for safety and efficiency.
view full answer... - Difference Between Curt Trailer Wiring Harnesses C56063 and Curt C56343Essentially the two wiring harnesses you mentioned are the same but with different converter boxes. The part # C56343 comes with a newer converter box that has a higher amperage rating so it would be much less likely to short out whereas the # C56063 uses Curt's older box that in our experience is pretty easy to short out. For that reason I would recommend the part # C56343 for your 2014 Ford Flex.
view full answer... - Does Tekonsha Trailer Wiring for 2019 Ford Flex Have Capacity to Power LED Trailer WiringYes, the taillight circuits of your 2019 Ford Flex will handle the amperage draw of the trailer LED taillights you have after you install the # 118472. We do have the Curt version part # C56343 which actually draws power for the trailer taillights from the vehicle battery as an option as well. If your trailer had incandescent bulbs or you wanted to be extra cautious in general this would be the way to go.
view full answer... - Is a Powered Converter Needed to Add Trailer Wiring for a 2011 Ford Flex SELIf your 2011 Ford Flex SEL did not come with a factory installed 7-Way trailer connector then you can either use the T-connector without the converter, # 118472, or you could use one with a powered converter, # C56343. Either harness will work. The benefit of having the powered converter is that it gets power for the trailer lights from the vehicle battery, not through the tail light wiring. This adds another level of circuit protection. Whenever there is a powered converter available for...
view full answer... - Trailer Wiring Harness for a 2014 Ford Flex without Factory Tow PackageTow Ready trailer wiring harness # 118472 is just one option for the 2014 Ford Flex. Its the only option that does not have a powered converter like you are describing (for models without factory tow package). There could potentially be too much power draw if you were to use this harness. Since that is a major concern for you I recommend using Curt harness # C56343 instead. It does require a direct connection to the vehicle battery. I have included a link to our help article with tips...
view full answer... - Is a Trailer Harness with Powered Converter Needed for a 2018 Ford FlexI have two trailer wiring harness options for a 2018 Ford Flex without factory tow package, the Curt T-Connector Vehicle Wiring Harness part # C56343 which has a powered converter or the T-One Vehicle Wiring Harness part # 118472 which doesn't have a powered converter. The powered converter will provide an extra level of protection for the vehicle's wiring and it will allow for trailers with more lights to be used. It is the better option but for some instances where the trailer is smaller...
view full answer... - Difference Between Wiring Harnesses for a 2009 Ford FlexYes, you are due to the power draw from the trailer. The dedicated 12v line that comes with the Curt T-Connector Vehicle Wiring Harness item # C56343 pulls power from your Ford's battery to operate the lighting functions on your trailer. This harness will power both incandescent and LED lights without having any issues like blinker's running faster. The Hopkins Plug-In Simple Vehicle Wiring Harness item # HM11140275 pulls it's power directly from the rear lights. If your trailer has a...
view full answer... - Trailer Lights Not Working After Installing Curt Wiring Harness on a 2011 Ford FlexThe first thing to check is if the Curt trailer wiring harness # C56343 for your 2011 Ford Flex is sending power through its converter box to the 4-Way like it is supposed to. Use a circuit tester such as # PTW2993 or a meter if you have one to test all of the input wires going into the converter box from the vehicle. Have someone sit in the vehicle and go through the various light functions while you test the input wires. If something is not showing power when it should on the input side,...
view full answer... - Recommended Trailer Hitch Receiver For 2019 Ford FlexI recommend the Draw-Tite Max-Frame Trailer Hitch Receiver # 75679 for your 2019 Ford Flex. This Class III receiver is capable of a maximum 400lbs of tongue weight and 4,000 lbs towing capacity. Be sure to check with your owners manual on what you vehicle maximums are and use the lesser of the 2 figures. The Curt T-Connector Vehicle Wiring Harness # C56343 will give you a 4-way flat trailer connector for when you need to connect to a small trailer, and it will also allow you to use Auxiliary...
view full answer... - Trailer Hitch for Flex and Towing Accessories for 2011 Ford FlexThe Draw-Tite Class III receiver hitch, part # 75679 weighs about 36 lbs, or 40 lbs as shipped. The hitch has a 4000 lb towing capcity and a 400 lb tongue weight capacity. If the towing capacity of the vehicle is less than that, you'll want to abide by the lowest rated component. If you'll be using the hitch for towing, you'll need a few other items to complete your towing system. Trailer wiring harness, part # C56343 or # HM40975 if the vehicle is equipped with the factory tow package. Ballmount...
view full answer... - Recommended Hitch for a 2011 Ford Flex w/ Dual Exhaust To add a hitch to your 2011 Ford Flex with dual exhaust, I recommend the etrailer item # e52AR. This hitch is custom fit and bolts to your Ford with included hardware. This is a class III hitch with a 2" receiver. It has a 4,000 lbs towing capacity and a 400 lbs maximum tongue weight. I have linked an installation video below so you can see how to get this hitch set up. f you are planning on towing you will also need a wiring harness item # C56343 and a ball mount kit item # C45534.
view full answer... - Weight Distribution Recommendation for Trailer that Weighs 4,000 lbsAll of the components you mentioned will do a great job for a towing setup for your 2017 Ford Flex and they are all linked below for you to check out but to answer your main question about weight distribution the way to do it is to base off of the loaded tongue weight of the setup. So since your trailer would be 4,000 lb you'd most likely have a tongue weight around 400 to 500 lbs so the system I would recommend is the Strait Line part # RP66082 which has a tongue weight range between...
view full answer... - Parts Needed to Add a Towing Package to a 2016 Ford FlexAccording to my research you can tow up to 4,500 lbs with your 2016 Ford Flex if you have the Class III Trailer Towing Package (which looks like it includes a 4/7 Way wiring harness, hitch receiver, trailer sway controller, and an engine oil cooler). If you don't have the Class III trailer towing package then you are limited to 2,000 lbs. We have compatible parts to "give" you the Class III trailer towing package but you will need to double check with Ford to make sure that it will still...
