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.

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.by: Kevin03/03/2024
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.

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.

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.

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.

You had what I couldn't find anywhere else thank you
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.
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.
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: Isaac P.06/02/2019
Great kit that worked very well! Some of the connectors were exposed and eventually corroded. This was remedied by cutting the connectors off and soldering the connections. In hindsight, I would recommend doing this initially for any exposed connections. Other than that I have no complaints.

- 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... - Right Brake Light on 2011 Escape Stopped Working After Trailer Wiring Harness Was InsatlledI would start by reviewing the installation procedure that I have linked you to. Make sure that the power connection is made to the battery, and not to another 12-volt power source. Ensure that the white wire is grounded to the vehicle frame or chassis. Check where the connector plugs into the rear of the passenger side tail light assembly. Make sure that the connector that plugs into the tail light is not damaged, and is fully inserted until it clicks. If all these items check out, then...
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...

In order to install the Curt # C56329 wiring harness, you actually have to remove the tail lights to gain access to the wiring that goes to them. The harness has connectors that plug in line with the tail light wiring and an additional wire must be run to the battery at the front of the vehicle to power the trailer lights. You could also...

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....
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... - 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...

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... - 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... - Replacement Trailer Wiring Harness Recommendation for 2011 Ford EscapeYou have adequately troubleshooted your trailer wiring harness to know that it is damaged and in need of replacing. Since the Curt converter boxes are known for shorting out easier I'd recommend you replace it with the part # 118551 which has a reputation as being more reliable. We don't have just the converter box available separately though.
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... - Curt Trailer Wiring Harness C56329 Blown Fuse and Will Not Work After Replacing FuseThe 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....
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... - 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... - 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... - 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...
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... - Should the White Wire Have Power on a Curt T-Connector Vehicle Wiring HarnessWhat do you mean by the white wire is not working? If you are using a circuit tester and testing the pin that corresponds to the white wire on the trailer connector then you should not have any power to this wire as it is a ground. Are the trailer lights working? If not then you may need to reattach the ground wire from the converter box to a clean bare (no paint) metal surface. Also, the Curt T-Connector Vehicle Wiring Harness is designed for a Dodge Caravan or Chrysler Town and Country....
view full answer... - Troubleshooting Hyper Flash on 2010 Ford Escape with LED LightsThe hyper flashing you're experiencing is caused becasue the LED lights draw much less power than incandescent lights. So essentially the vehicle senses the low power draw and believes a bulb has burned out.

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...

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...
