CURT Custom Fit Vehicle Wiring

  • Custom Fit
  • Trailer Hitch Wiring
  • 4 Flat
  • Converter
  • CURT

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.


Features:

  • Provides a 4-way flat trailer connector at the back of your vehicle to power your trailer's signal lights
    • Compatible with 5-pole, 6-pole and 7-pole adapters (sold separately)
  • Connects quickly and easily
    • Locate connection points behind tail lights
    • Plug in T-connector
    • Run hot lead to car battery
  • Includes a tail light converter to ensure that your vehicle's wiring matches that of your trailer
    • Powered module connects directly to battery to avoid overloading vehicle's electrical system
  • Constructed using surface-mount technology (SMT) for consistent, reliable performance
    • Maximizes trailer light yield and intensity while producing minimal heat
    • Ensures superior operation in rough road conditions
  • Comes with dust cap for 4-way flat connector


Specs:

  • Maximum amperage:
    • Stop/turn lights: 5 amps per circuit
    • Tail lights: 7.5 amps per circuit
  • Limited 1-year warranty


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 beneath your vehicle, near the trailer hitch. A mounting bracket (sold separately) is recommended to keep the connection secure.


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.


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.


Curt SMT Circuit Boards

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.

Excellent product! Hitch and wiring kit. Installation was a breeze. Works great! Shipping was stupid fast! Will buy all my towing products from Etrailer!! Awesome company.

Ford Edge

I found the install to be easy per video. I installed a factory hitch and installed the curt T-Connector and on my 2022 Ford Edge. I unscrewed the fenders and pope them lose and was able to just slide the wiring to the rear tail light in proper place instead of fishing and get it stuck. The hot wire was a little challenge do to there was not really any good place to route to battery



by:

My order was shipped a lot faster than i ever expected, Christmas week, 3days



by:

everything came as ordered if I had any complaint it would be the wire connectors I feel they should be a heat shrink type. I replaced mine with heat shrink type connectors there for four stars instead of five.

I like the hitch and the bracket that I bought so the trailer light wire isnt just hanging it look nice and professional



by:
2022 Ford Edge

Always have a great experience when buying from trailer. Good quality products. Have one suggestion. When shipping small items inside larger boxes should be protected. The wiring harness was shipped inside the box with the hitch receiver. Which is understandable. The package the harness was in came open and the parts were all over inside the larger box. The staples holding the box closed from the factory did not hold. The package should have been taped to keep it closed. Fortunately nothing was damaged.



by:

etrailer is a great company with a lot of options.please use their customer service to ensure you are purchasing the correct item.i misread and purchased a cheaper wiring harness that would not connect to my taillight.they are going to refund my money but not asking first cost me three days.the hitch worked purfect.



by:

Great service. The videos are the best. Much more info than the paper instructions.



by:

Great product…just need better quality screws or pre drilled holes in tow hitch…



by:
2020 Ford Edge

Be SURE that you understand it takes 6 business days ARO to receive, unless you upgrade shipping.



by:

The plug-in installation went well. The wiring harness made the job look professional. The instructions were very clear and easy to follow.



by:

Easy plug and play once I got the taillights off. All wires fit inside the left taillight housing. Biggest issue was running the power wire to the front to the battery.



by:

The installation video really helps.

  • Can Curt Trailer Wiring Power be Connected to 12V Plug in Back of 2019 Ford Edge
    We get this question a lot and while you can technically install the Curt T-Connector Vehicle Wiring Harness # C89FR in whichever manner you want, if you connect the power wire to that 12V plug on your 2019 Ford Edge as opposed to the battery you run the risk of overloading that circuit and voiding your warranty. Because of this we always recommend routing the power wire directly to the battery, per the instructions, to protect the OEM wiring on your vehicle. Running the power wire to...

  • Which Curt Wiring Harness for a 2020 Ford Edge SE or SEL
    The # C89FR has the manufacturer's part number 56436, which is the CURT T-Connector Vehicle Wiring Harness with 4 Pole Trailer Connector. This harness is a confirmed fit on your 2020 Ford Edge as long as you have either the SE or SEL trim package. I've also linked the installation video of this part for you to check out, as well.

This fully welded Ford Edge trailer hitch is strong and durable. I have attached a picture and an installation video so you can see the final look and install process.

  • I do have a solution for you, but after looking at the online owners manual for the 2021 Ford Edge, it does not appear that they equip these with a factory brake control port. So I would not be able to offer you a plug and play harness for the Tekonsha Prodigy P3 # 90195 at this time. We can definitely still help get your brake controller installed. If you are in need of a 4-pin harness, we have part # C89FR which will fit SE and SEL models, Or part # C73FR which is for the Titanium...

  • Will Installing Trailer Hitch on 2009 Ford Edge Cause Hands-Free Liftgate Not to Work
    Installation of the Draw-Tite # 75234 Class III hitch on your 2019 Ford Edge will block a portion of where the sensors can 'see', but the liftgate will still function. Usually on the Ford vehicles, the areas about 3-6 inches to the right and left of the receiver tube over to the corners of the vehicle will still work just fine. I do know that some vehicle manufacturers like Honda offer relocation brackets for the liftgate sensors, but I have not been able to find anything for the 2019...

  • Does the Draw-Tite # 75234 Allow Me to Use My Hands-Free Liftgate Sensor on My 2021 Ford Edge?
    Yes! The Draw-Tite Hitch # 75234 will work with your hands-free liftgate sensor on your 2021 Ford Edge. You will just need to have a little wider kick to activate the sensor once the hitch is installed. If you plan on towing with the hitch, I recommend a ball/ball mount like the ones included in the Curt Towing Starter Kit # C45534. Not only does this kit come with a hitch cover, but it also comes with a locking hitch pin. Also, if you need trailer wiring, I recommend the following harnesses...

    When it comes to installing a trailer hitch on your 2022 Ford Edge I recommend The Curt Trailer Hitch Receiver - Custom Fit - Class III - 2 inch # C78KR. This hitch has a concealed cross tube so you will only see the hitch head after installation. The hitch has a gloss black powder coat finish over a protective base coat which offers superior rust resistance. The trailer hitch has a simple bolt on installation with no welding required.

  • Do All of the Hitches for a 2020 Ford Edge Require Moving the Exhaust?
    All of the hitches for a 2020 Ford Edge require the exhaust to be lowered. It sounds more complicated than it really is. You have to disconnect the rubber hangers that hold the exhaust up to get behind them and install the hitch. The muffler and tail pipes just hang down a few inches while you're doing this. You don't ever remove them from your vehicle. I recommend the etrailer Hitch item # e36RR. This hitch is custom fit and bolts to your 2020 Ford Edge with included hardware. This is...

I have included an image with the receiver installed so you better understand how it will look on your Edge. You will want to install the 4-Way # C89FR when you install the receiver. This will allow you to connect to most small trailers you might tow. It will also allow for Auxiliary Lights...

  • Can Curt Dual Hitch Adapter Be Used with Subaru Outback to Carry E-Bikes and Tow Trailer
    The Curt hitch part # C89FR that you have installed on your Outback has a higher tongue weight capacity so what you are looking to do with the Curt dual ball mount # D210 could possibly work. You should note that when you use the # D210 with a bike rack in the upper hitch opening you cut the capacity of the hitch by 50 percent so with the Curt hitch you have you'd be limited to 300 lbs of tongue weight for the trailer and you e-bikes. Then for a bike rack the Thule EasyFold XT part #...

  • What is the Best Hitch for a 2023 Ford Edge?
    The best hitch for a 2023 Ford Edge is going to be the etrailer item # e36RR. This hitch is custom fit and bolts to your Ford Edge with included hardware. This is a class III hitch with a 2" receiver. I really like this hitch because the crosstube installs completely behind the rear bumper cover. This leaves only the 2" receiver visible so you won't have to worry about it hanging down or seeing much of it. Uhaul trailer's require 4-way connectors. There are two options for your vehicle...

  • Do I Have to Remove the Bumper Cover When Installing a Hitch on a 2023 Ford Edge?
    No, it does not. The Curt Hitch item # C78KR does not require you to remove your rear bumper cover when installing it on a 2023 Ford Edge. It bolts to the bottom of the frame and the crosstube is concealed behind the bumper cover. I have an alternate suggestion for a hitch. Instead of the Curt item # C78KR, I recommend the etrailer Hitch item # e36RR. These hitches are identical with the exception of cost and the paint finish. The item # e36RR is our house brand hitch but it is made by...

    You can still go with the Curt Echo # C51180, even with your phone handling all those functions. Though you will need your phone for the initial set up, you can then use the Manual Override Button # C83HR. Manual override is the only function the phone will handle after getting everything set up and running properly. I can say that your 2021 Ford Edge will not have a brake controller fuse, so you may need a few parts to get the controller the needed power, depending on what you have on...

    Installing the Draw-Tite # 75234 Class III hitch on your 2021 Ford Edge will interfere a bit with the operation of the hands free liftgate feature, but it won't prevent it from working. The sensors under the center portion of the bumper will be blocked by the hitch receiver opening, but the areas to the left and right will still work, as shown in the photo I've provided for you.

For a 4-way and 7-way you will need a combination of parts. First you will need a T-One Vehicle Wiring Harness.

  • Parts Needed to Install Brakes on Trailer with 3,500 lb Axles

These assemblies will work well for your axles and are self adjusting. Then for hub/drum I recommend using the Trailer Hub and Drum Assembly - 3.5K E-Z Lube Axles - 10" Diameter - 5 on 4-1/2 - Pre-Greased # AKHD-545-35-EZ-K.
