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. 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.
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.

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.

2012 Ford Escape
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!
by: DW06/26/2022
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.

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

Working perfectly.

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.

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!

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.

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.

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 Ford Escape
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.
by: Richard 08/31/2023
works excellent.
by: Richard07/31/2019
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 Ford Escape
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.
by: Grant03/10/2022
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.
by: Atanacio07/30/2022
As usual, etrailer stuff is great. This, just like my two Priuse's harnesses fit perfectly and include all the parts to finish the job and have a reliable installation.

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!
by: Ross 04/12/2020
2011 Ford Escape
This order arrived quickly. It is extremely easy to put together with basic hand tools. The wires and plugs are made of good quality. I recommend buying heat shrink connectors instead of using the ones provided (more weather proof). You may need/want some extra zip ties. All in all I would buy it again.

See what our Experts say about this CURT Custom Fit Vehicle Wiring
- Is the Curt T-Connector # C56329 Compatible with a 2012 Escape with Backup SensorsYes, 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.
view full answer... - Power to Curt 4-Way Trailer Wiring Harness on a 2011 Ford Escape when Turned OffThis is a common occurrence on some Curt trailer wiring harnesses such as # C56329. Normally you would not notice unless the trailer was connected and it had LED lights. 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. Just to be on the safe side make sure the ground is connected to a clean bare metal surface and that all the connections to the tail light...
view full answer... - Trailer Hitch Receiver & Wiring For 2010 Ford EscapeThe 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.
view full answer... - Trailer Wiring for 2011 Ford Escape with Blue Ox Tow Bar WiringFor your 2011 Ford Escape that has the Blue Ox tow bar wiring diode kit you can still install trailer wiring like the Curt # C56329 which will install by plugging inline with the vehicle taillight connectors.
view full answer... - Trailer Hitch Cover Light Stays On with 1-Year-Old Curt Trailer Wiring Harness on a Jeep CompassOver time, the trailer wiring harness you have installed could have gotten corrosion or moisture on the contacts, pins, ground, or even in the converter. What I recommend is to go over all of the connection points, make sure they are cleaned out, check the wiring for any nicks and repair as needed. Make sure the 4-Way end is free of corrosion and that the grounds are still firmly attached to bare metal. If you do all of this and still have the problem then it is likely that the problem...
view full answer... - Towing Capacity of Curt Class III Trailer Hitch for a 2009 Lincoln MKXThe maximum towing capacity for Curt Class III Trailer Hitch, # C13067, is 4,000 lbs. The maximum tongue weight capacity is 400 lbs. Keep in mind, these are the maximum capacities for the hitch. It is important for you to check your owners manual to verify the actual towing capacities of your vehicle because they could be different. If you plan on doing some towing, then you will also want a wiring harness, # C56329, and a ball mount, hitch ball and a pin and clip. We offer the etrailer.com...
view full answer... - Troubleshooting No Brake Lights on Vehicle Side of Wiring Harness for Possible Converter FailureTo 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...
view full answer... - Lamps of Trailer Pulled By 2016 Ford Escape Stay Illuminated With Vehicle and Lights OffThe 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...
view full answer... - 4-Pole Trailer Wiring Harness for 2009 Ford EdgeWe do offer 4-pole trailer wiring harness kits for your 2009 Ford Edge that will provide stop/turn/tail light functions to your trailer's lights. All available items are shown on the linked page. Each of these installs in the same way by 1) plugging in at your Edge taillights and by 2) routing one single 12V power wire up to the engine compartment for connection to the battery. This is the only type of aftermarket harness offered for your car. Of the three I recommend the Tekonsha kit...
view full answer... - Will Curt Trailer Hitch for a 2008 Ford Edge Have Capacity for 3,200 lb TrailerThe towing capacities of the Curt Class III hitch part # C13067 that you referenced are 4,000 lbs total trailer weight and 400 lb tongue weight. Your 3,200 lb trailer would fall under the capacity of the hitch so it would work just fine. I attached an install video for this hitch for you to check out as well You should note that this hitch is not rated for use with a weight distribution system. If you are unsure what a weight distribution system I attached a help article that covers them...
view full answer... - Recommended Towing Package For Towing a Utility Trailer With a 2010 Ford Edge SportI 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"...
view full answer... - Trailer Wiring Harness Recommendation for a 2010 Ford EscapeThe 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...
view full answer... - Trailer Wiring Harness Converter Boxes No Longer Working After 1 Year of Use on a 2008 Ford EscapeThe 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....
view full answer... - Troubleshooting Driver Side Turn Signal Not Working on 4-Way for 2009 Mazda TributeSince only one function is not working it doesn't sound like it is the converter box. Although there could be a problem with the connectors, there should be no real loss of conductivity over time. It is possible that the # C56329 needs to be replaced, but there are a few things you can check first before going that route. The first thing I would do is double check the connectors. If the connector is not fully seated and came apart over time it could explain why it went out intermittently...
view full answer... - Mercedes ML350 Does Not Work with a Trailer that Has LED Tail LightsGerman 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....
view full answer... - Parts Needed For Adding a Trailer Hitch Receiver, Wiring and Brake Controller On a 2008 Lincoln MKXThe 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...
view full answer... - 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...
view full answer... - Universal Hardwire Trailer Wiring Harness Blowing Fuses on 2011 Ford EscapeI agree that it does sound like there is a short inside the converter box. You can also check for any of its wires touching bare metal but based on the description of the problem and what you have already checked it does sound like it is internal. If it were me I would go with Tekonsha harness # 118551 because we hear about fewer problems with them. This is also a powered harness and I do recommend running the new power wire to eliminate the old wiring as a variable in the malfunction...
view full answer... - Could Testing Trailer Wiring Pins with Circuit Tester Cause Fuse to BlowThe only way the multimeter could have possibly blown the fuse is if one of the probes ended up touching the ground pin and one of the active pins at same time as that would create a short. Otherwise the short is on the trailer wiring which is probably the more likely situation as this is a common problem that takes out the converter boxes. So I'd recommend going over the trailer wiring looking for any cut or exposed wire and fixing as needed.
view full answer... - 2007 Ford Edge Correct Trailer Wiring HarnessThe Curt T-Connector Vehicle Wiring Harness # C56329 tees in behind the tail lights on your 2007 Ford Edge and then pulls power directly from your vehicle battery (via the included lead) so you don't overdraw the circuits on your vehicle when you have a trailer hooked up. The Curt T-Connector # C55265 you referenced is only confirmed to fit a 2002 - 2004 Ford F-250/F-350 with a factory 4-Flat connector. It has never been confirmed to fit a Ford Edge so if you decided to still go with this...
view full answer... - Running Lights Do Not Work on Trailer Towed by a 2010 Ford EdgeThis sounds like a classic ground issue that could be the result of a bad or corroded connection, a loose wire, or a dirty/corroded trailer connector. The act of towing the trailer causes some movement and the ground connection changes slightly to where it was working when you had stopped. What you will want to do is make sure the main ground on the converter on the vehicle is connected to a clean bare metal surface. Verify with a circuit tester like # PTW2993 if needed that the running...

The unit I recommend for your MKX is the custom plug-in harness from Tow Ready, part # 118551. This trailer wiring harness installs by plugging in to your MKX's tail light wiring; just one spliced connection is required, for the 12V power input wire to the converter. This connection is made from the short wire on the converter box to your battery's positive terminal, through the included fuse...
view full answer... - Trailer Lights Stopped Working when Connected to a 2010 Ford EscapeWe will need to determine where the problem is. To do this you will need a circuit tester such as # PTW2993. Test the vehicle side connector with the circuit tester while someone sits in the 2010 Ford Escape and activates the lighting functions (turn signals, brake lights, and running lights) while you test the connector. If there is no power on the 4-Way when performing the test, then perform the same test only this time test the wires going into the converter from the Escape (instead...

The reason for this is the power wire for the # C56329 uses a 15 amp fuse as it is just for powering the converter for the lights, where the black wire of the # C57672 is for the 12v trailer battery circuit which uses a 30/40 amp circuit breaker.
