- Reliable Lighting Setup: 4-flat output works with standard trailers and rental units.
Features to know about
Installs Without Cutting or Splicing: Plug-In T-Connector
This harness plugs inline with the tail light wiring, so there’s no cutting or splicing needed. The connectors match right up with the factory plugs, making it a clean and simple install that doesn’t disturb the existing wiring.
Protects Vehicle Wiring: Powered Converter Design
The built-in powered converter takes the load off the vehicle’s delicate tail light circuits by drawing power directly from the battery through an independent lead. That means the trailer lights get full, steady power without risking damage to the vehicle’s electrical system.
Covers Trailer Light Basics: 4-Pole Flat Output
The 4-pole flat connector gives you running lights, brake lights, and turn signals—everything you need for standard trailer lighting. It’s the common connection used for small utility, boat, or rental trailers.
Keeps Electrical System Safe from Shorts: Isolated Converter Protection
If a short or overload happens on the trailer side, the converter box isolates it from your vehicle wiring. In that situation, the converter takes the hit instead of your car’s circuits, preventing expensive electrical damage and keeping your system safe.
Clean Install Every Time: Hidden Plug-In Fit
The hidden plug-in design routes behind trim panels and tail lights for a tidy look with no loose wires showing. When you’re not towing, you can tuck the 4-way connector out of sight to keep everything protected and out of the way.

Wire harness speed with the receiver hitch I ordered. Shipped on time and in good condition. I like that this harness allows a harness installation without having to tap into the vehicle wiring for power. The only suggestion I would make is to include more than 4 ties to install harness across bottom of vehicle. I had plenty at home so it wasn't a big deal. I'm probably being picky but I do believe to keep the harness away from moving, there should be more tires. The harness is high quality. It was plenty long for the install. The connectors were tight fitting which was fine with me. The order process was very easy. Very happy with this product. I bought this harness to run the lights on my bike rack for a road trip we are currently on. Works great!

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.

Easy to install, made even easier with your installation video. The design of the harness minimizes the amount of wire cutting/splicing/crimping/etc. Best of all, it worked the first time I plugged into a trailer! Not that I expected it not to, but that was super validating.

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.

It took me a little longer than expected, I am not as flexible at 65 moving under the vehicle to wire it to the battery. But it is neatly secured and all is working correctly. This is my 3rd hitch installation on different vehicles

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.

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.

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.

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.

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.

I love Etrailer.com. 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 etrailer.com

- Recommended Wiring Harness for a 2008 Ford Escape Hey Luis. Since your 2008 Ford Escape doesn't have the tow package, you'll need the Curt T-Connector Vehicle Wiring Harness item # C56329. This wiring harness includes custom fit connectors that will plug directly into the wiring behind your Escape's tail lights. It will provide you with a 4-flat connector. The Curt item # C56329 does not require any additional relays to be installed. It includes the necessary fuse you'll need to power the harness after you get it installed. I've linked...

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... - 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...

I recommend the etrailer Trailer Hitch Receiver # e98870. This is a Class III hitch with a bolt-on installation and a limited lifetime warranty. It also comes with a unique matte black finish which helps hide dirt and scratches.

view full answer... - Troubleshooting an LED Trailer Light Staying On When Vehicle is Turned OffThis 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...

The first thing that we can test for is a bad converter box. With the fuse in place, test the 4-flat connector on the wiring harness without any vehicle lights on using a circuit tester with an incandescent bulb like part # PTW2993. Be sure to test each pin. If there is constant power on any of the pins with the vehicle lights off, then the converter...
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.

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... - Why Does the Curt Powered Taillight Converter Have a Wire that Runs to the BatteryThe 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.

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. Installing the load resistors # DI34ZR on the turn signal circuits will add more resistance and prevent the hyper flashing. I've linked the insallation instructions of the load resistors for you as well.

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.

The act of towing the trailer causes some movement and the ground connection changes slightly to where it was working when you had stopped.

With Class I and II hitches you are supposed to use the ball mount specified by the hitch manufacturer for warranty reasons. Class I and II hitches are tested with and given their rating based on a specific ball mount which is why you are supposed to use that specific ball mount.

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...
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...
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.

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...

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.

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.
