2009 Ford Escape - Curt T-Connector Vehicle Wiring Harness with 4-Pole Flat Trailer Connector

  • 4 Flat
  • Trailer Hitch Wiring
  • Powered Converter
  • CURT

Quickly and easily install a 4-way trailer connector on your Ford Escape 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.


  • 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 powered tail light converter that 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


  • Maximum amperage:
    • Stop/turn lights: 3 amps per circuit
    • Tail lights: 6 amps per circuit
  • Limited 1-year warranty


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. 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.

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.

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.

Curt T-Connector Vehicle Wiring Harness with 4-Pole Flat Trailer Connector - C56329

Average Customer Rating:  4.8 out of 5 stars   (157 Customer Reviews)

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.


Pretty easy install worked great and still working great a year later. Hardest part was finding a good location to mount the controller below driver side tail light but figured it out and watched a YouTube video but the mounting of the controller wasn't in the video they skipped that step. Ran the 12 volt power lead wire up to engine bay along driver side frame rail and attached to brake lines and fuel lines with zip ties.


After one year no issues with this harness. Trailer lights power up every time.


The installation was a breeze. I didn’t even have to jack up the car. It has worked well since installing it.


Setup went well


This harness appears to be of excellent quality, and is the perfect thing needed to set up my vehicle for utility lights the right way. The only reason for four stars is that I have not actually installed it as yet, so have not had opportunity to test it.



Well over a year and product is just fine. Thank you for the follow up!

2012 FordEscape

Showed up timely and fit like a glove on our 2012 Ford Escape. The wiring harness was very easy and directions easy to follow. The hardware for hitch was all there and also easy to install. Thanks!


this was one of the best companies to deal with. they kept in contact the whole time. they made sure everything arrived on time. that, to me is priceless... the hitch and harness is great. easy instalation. looks super.. I am extremely happy with the whole process.... top notch everyone....


I wired my Harness in myself and a year later it's still Top Notch? Excellent product.

2008 Mazda Tribute

Worked great and still working great after a year


Good product bad was the wiring for the box was short


can't believe it arrived in less than a week! Best price I found online. Fit perfectly and only took 30 min to install. Happy to write a review for future customers since past reviews were what tipped my vote. Thank you etrailer!


Was easy to install the directions could have been little better to work out but i watched video of it and was simple. Hardest part was running wire to battery.

2012 Chevrolet Volt

The wiring harness came with everything I needed for the installation. The hardest part of the installation was running the 12 volt power wire from the rear of the car to the engine compartment. I purchased the optional weather-proof connector wit the heat shrink tubing. This ensures a good waterproof connection for the wiring. The only minor complaint that I have is that I don't like the dangling trailer electrical plug-in. It would be nicer if the plug-in could have been mounted to the bottom of the bumper.



This trailer wiring harness has functioned flawlessly and is holding up to frequent use quite well. However, I still think that the connection point for the trailer plug in should have a bracket or clip to firmly attach to the rear bumper of the vehicle.


Awesome, helpful staff, set me up with the right wiring kit.
Working perfectly.

2012 FordEscape

Ordered a hitch and wiring for my 2012 escape.wiring was not available.called and talked to Stacey who found another available harness had them both shipped out and received them in 5 days.i had already read on their website how to install them.i have above average installation skills and installed the hitch and wiring in about one and a half hours.very pleased with quality and ease of install.service was also excellent.

Charles T.


Have had no problems hitch and wiring works great very good quality and ease of installation.


Clear well written instructions and videos. Took less than 30 mins for 16 yr old to install


It was easy to install

2008 FordEscape

Harness fit good and was easy to install. Only four stars because the video had stated the connectors were upgraded to heat shrink connectors but my connectors were not. I did have some of my own so I swapped them out.

Etrailer Expert

Rachael H.


This kit included standard butt connectors, but as referenced at about 4:10 in the video the connectors were upgraded to part # DW05745-10. A link to those upgraded heat shrink connectors can be found here.

2010 FordEscape

This was my second trailer wiring kit for my 2010 Ford Escape. The first one stopped working correctly after about 4 years due to somehow the little module that was mounted with double sided tape behind the tail light came loose and was dangling down where it was exposed to the elements. The second unit was mounted with a screw and worked like a charm. The only minor difficulty is running the power wiring up to the battery in a manner that it is protected and out of the way. Other than that, easy fast installation in one evening. I’ve since traded that vehicle so I can only assume it’s still working.


Excellent fit


Very satisfied with the product. The package arrived a little beat up with a significant gash in the side of the box, but the hitch was undamaged and all parts were intact. The hitch installed easily, everything fit as needed, though why the need for a spaced between the hitch and the frame on the passenger side really doesn't make sense, it looks like a fix for a hitch with incorrect mounting hole locations. And that did make the installation a little more difficult, but manageable. The wiring harness also installed easily, everything needed was there and everything worked as it should. I'm quite satisfied.

2011 FordEscape

Installed this on my son's 2011 Ford Escape. Using the simple to follow instructions and the Videos provided by Etrailer made this a simple project. We installed this in conjunction with a receiver hitch, which we also ordered from Etrailer.


Harness is of good quality and plugged right in to the factory wiring. Easy to install other than having to run a wire back to the battery to power it. The separate power is nice in that the trailer light circuit is isolated from your vehicle tail lights and turn signals.

2012 FordEscape

I love The right parts for the job always. Shipping is prompt. Prices are fair. If you need to return an item there is never a hassle. This new harness solved my suspected control module problem. Trailer Brake lights stuck on. Upon braking, the opposite trailer turn signal would come on. Thanks

2010 Mazda Tribute

Great assistance with determining & ordering trailer hitch, ball & receiver and wiring harness. Product arrived promptly as expected and is now installed on my 2010 Mazda Tribute. Thanks for the expert assistance!

  • Parts Needed For Adding a Trailer Hitch Receiver, Wiring and Brake Controller On a 2008 Lincoln MKX
    The Curt Trailer Hitch Receiver # C13067 is confirmed to fit your 2008 Lincoln MKX. This class III receiver is rated for up to 400lbs of tongue weight and a trailer up to 4,000lbs. Be sure to verify your maximum trailer capabilities with your Lincoln dealer and do not exceed the lower of the limits. You will need the Curt T-Connector Vehicle Wiring Harness # C56329 for your MKX, as the # C55326 you found fits older Ford cars and not your MKX. The Harness # C56329 will give you a 4-way...

  • Recommended Towing Package For Towing a Utility Trailer With a 2010 Ford Edge Sport
    I recommend installing the Draw-Tite Trailer Hitch Receiver # 75686 on your 2010 Ford Edge Sport. I feel this one looks better than the etrailer # e98870 you found as the Draw-Tite has a hidden cross tube which will sit behind the rear fascia. The Curt T-Connector Vehicle Wiring Harness # C56329 will give you a 4-way flat connector. This is the most common connector used on small single axle utility trailers. Our Ball Mount Kit # 989892 will provide you with a ball mount having a 2-3/4"...

  • Troubleshooting A Trailer Wire Harness On A 2011 Ford Escape That Keeps Blowing Fuses
    Hey Johnathan, The Curt T-Connector Vehicle Wiring Harness with 4-Pole Flat Trailer Connector # C56329 requires a 10 amp fuse so I'd first make sure you're not putting a lower rated fuse in place. The next step is checking the wiring for any cuts or kinks that could potentially cause a short, but you've already done that. Did you mount the ground wire coming from the converter box to the frame of the Escape? A bad ground could be the cause of the short. If everything checks out then I'd...

  • Comparing Tekonsha and Curt Custom Fit Vehicle Trailer Wiring for a 2007 Ford Edge
    If I were choosing between the Tekonsha harness, # 118551 and the Curt wiring harness, # C56329 for a 2007 Ford Edge, I would go for the 118551. Tekonsha has been in the wiring business longer, they have great support, and they work well if you take care of them (make sure to keep the 4-Way clean, store it in the vehicle when not in use, stay within the amperage limits). The Curt harness will work, it is not an inferior product, it is just that Tow Ready has more of a pedigree than Curt....

    Yes, the Curt T-Connector Vehicle Wiring Harness with 4-Pole Flat Trailer Connector # C56329 is compatible with your 2012 Ford Escape whether it has backup sensors or not. I have attached a video of this kit being installed on a similar 2012 Escape for you to check out. If you are using the wiring for a towing setup and are in need of any other equipment just let me know and I can make some other recommendations for you.

  • Curt Trailer Wiring Harness C56329 Blown Fuse and Will Not Work After Replacing Fuse
    The likely problem is a blown converter box. If there was short circuit on the trailer side that was bad enough it could blow the fuse on the power wire and/or the converter box. If this happens the converter did its job of protecting the vehicle. Since a new fuse as not resurrected the converter it will need to be replaced. However, before you do so you will want to take care of the short circuit. Start by checking the trailer side connector, making sure it is clean and free of corrosion....

  • Why Does the Curt Powered Taillight Converter Have a Wire that Runs to the Battery
    The reason the Curt Custom Fit Vehicle Wiring # C56329 has a power wire is to protect the delicate tail light wiring circuits of your vehicle from being overloaded. The Curt Trailer Harness # C56329 that you referenced uses your tail light circuits as signal wires and then draws the power to illuminate the tail lights of your trailer directly from your vehicle battery through the battery wire of the box. I attached installation instructions, an installation video and an FAQ on routing...

  • Troubleshooting No Brake Lights on Vehicle Side of Wiring Harness for Possible Converter Failure
    To determine if your converter is bad on your wiring harness you can do a couple of quick tests using a circuit tester like # PTW2993. Test the brake wires for each side coming out of the converter when the brake pedal is pressed. If you get no function then test the wires going into the converter. If you have power going in and not coming out, then it is definitely the converter and it will need replaced. If you don't have power even reaching the converter then test the harness where...

  • Trailer Wiring Harness Recommendation for a 2010 Ford Escape
    The Curt T-Connector Vehicle Wiring Harness # C56329 that you referenced would be the correct wiring harness for you to use on your 2010 Ford Escape. The reason you have to run a wire up to the battery is to prevent amperage draw on your vehicles delicate tail light circuitry. If you were to attempt to install a wiring harness that does not draw from the battery you would most likely overload the tail light circuitry of your vehicle and possibly damage it. Running the power wire up to...

  • Troubleshooting an LED Trailer Light Staying On When Vehicle is Turned Off
    This can occur with some Curt wiring harnesses. On a trailer with LED lights the lights may be dimly lit when the vehicle is off because the harness has a direct connection to the battery and there is some power to the 4-Way all the time. If the lights are coming on as bright as normal the first thing, I would check would be the 4-way trailer connector that is on your both of your vehicles. It sounds like the problem is in your trailer, but it is still a good idea to rule out the vehicles...

  • Trailer Hitch Receiver & Wiring For 2010 Ford Escape
    The trailer hitch receiver I recommend for your 2010 Ford Escape is the etrailer Trailer Hitch Receiver # e56AR. I like the # e56AR because of its matte black finish that hides the inevitable dings, scuffs, and scratches better than any other option. And while it does not come with a 4-way wiring harness you can get one separately, with the correct fit being the T-Connector Vehicle Wiring Harness # C56329. The # C56329 does work on models without backup sensors.

  • Lamps of Trailer Pulled By 2016 Ford Escape Stay Illuminated With Vehicle and Lights Off
    The most likely reason for the trailer wiring harness to put out voltage with the vehicle shut off is a shorted converter box which is caused by a short circuit in the trailer wiring. You can confirm this by removing the 10A fuse in the yellow fuse holder that should be connected to the vehicle's positive battery terminal. If removing the fuse causes that light that remains on to shut off, it confirms that the converter box has a short circuit in it. You'll need to identify the short...

  • Mercedes ML350 Does Not Work with a Trailer that Has LED Tail Lights
    German engineered vehicles such as your Mercedes ML350 do have problems with LED trailer lights. A powered converter could solve the issue but there are also special adapters that create more draw that will allow the affected vehicles to tow a trailer with LED lights and not have that bulb out sensor issue. I would need to know the year of your Mercedes ML350 to make a wiring harness recommendation. You would need to have a 7-Way wiring harness on the vehicle already to use the adapters....

  • Trailer Wiring Harness Converter Boxes No Longer Working After 1 Year of Use on a 2008 Ford Escape
    The problem could be corrosion build up at the trailer connectors that is causing a short or another wiring issue on the trailer that is causing a short. If this is the case, then the harness # C56329 is actually doing its job of protecting the vehicle wiring by shorting out at the converter rather than the vehicle. You will want to check your trailer connectors frequently before use for any corrosion, clean out the connectors, and make sure the wiring harness ground connection is intact....

  • Troubleshooting Bad Converter Box on Trailer Wiring Harness for 2011 Ford Escape
    It does sound like the converter box on your existing wiring harness has gone bad. We do not have replacement converter boxes available, so your best option will be to replace the harness altogether. For your 2011 Ford Escape, I actually recommend going with the Tekonsha T-One Vehicle Wiring Harness # 118551. This will install just like your existing harness, by plugging into factory ports behind the driver and passenger side tail lights and then running the hot lead up to the Escape's...

Then you may get a faint glow out of the lights. Having power to the 4-Way is not going to hurt anything or run down the battery unless there is something plugged in drawing the power.
