  • Trailer Hitch Wiring
  • 4 Flat

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.

    • Tail lights: 6 amps per circuit
  • Limited 1-year warranty


Installation

This custom-fit T-connector plugs into your vehicle's wiring harness, which is located behind your tail lights. You will have to remove the trunk floor coverings, storage trays, rear scuff panel, trim panel, and tail lights 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 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.


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.

Works well. Plug/connector is a little tight to trailer plug. Routing the wire to battery is a little tricky. Wish it would connect to fuse block in the trunk



by:

Wiring harness delivered quickly amd complete. With the help of a youtube video was easy to install. Great product



by:

Excellent product, promptly shipped. Clear and concise installation instructions. Still working well after a year of service.



by:

The wires from the 7-way are too long so the weather protection cover doesn’t reach the 7-way plug. The wires show about an inch. Can I return it?
Attach any photos of the product you would like

Ford Escape

did get the receiver on date that i was told.
box had holes in it that were the size of a softball , not the fault of etrailer. little paint missing.
i was happy they put the wiring in bigger box, so it did not fall out.
i think it was my 3 hitch off them.
one thing i figured out, put hitch on escape ,put the front in first and rolled it up in.
40-45 mins done,once i thought to roll it in.
wiring little bit longer,but all done.

2017 Ford Escape

Product is perfect. Installation on a 2017 Escape is a pain, but generally straightforward. There is no way around that as the escape was not built with a factory harness trailer plug outlet. Have to run a separate power line to the battery under the hood. It’s all accurately outlined in the instructions and installation videos.



by:

Easy to install and the videos do help a lot.

2018 Ford Escape

I haven’t actually installed it yet (too many other projects lol) but i think it’ll go just fine since I watched the tutorial on the site. Appreciated it. I like the quality of the product as well, just based on looks alone.. lately, was getting used to cheap stuff from China that isn’t built the best but this is so much better. Easy to follow instructions as well. No need for a translator

Great question! The harness has a one year warranty.



by:

I was satisfied with shipping speed. Item was easy to install and is working as described. The video provided on etrailer site was very helpful in the installation, mainly because it showed how to install it on the make and model of my car. The video is the main reason I ordered from etrailer.

I have had no problems with the t connector. I did not connect the hot wire to the battery. I connected an old style cigarette lighter plug to the power wire along with the included fuse holder which I plug into the 12 volt power outlet in the storage area of my 2018 Ford Escape.This provides plenty of power to power the lights on my boat trailer which is all Leds. It would probably power about any trailers lights. I store it under the spare tire cover when not in use.

Etrailer Expert

The power wire must be run to the battery as specified in the installations. The rear cigarette lighter outlet cannot be used for this purpose as it does not have the proper rating so it could short out your wiring or your vehicle's electrical system.


by:

Excellent!

Very happy with the product, love the way it looks and only the tongue can be seen. The how to video was instrumental and well-made. The entire process from Ordering to this review has been excellent! What a great company!

I have towed my utility trailer several times, and couldn’t be happier with the hitch. I was thinking about buying a pickup truck, but by installing the hitch, I got the hauling capacity I needed for a lot less money. I also plan to buy a cargo carrier for deer season so I don’t have to haul game inside my Escape



by:
Ford Escape

Wiring harness installed just fine. Took twice as long as putting the hitch on though as much to take apart. Video helped but my Escape had more accessory items wired in back than what video showed so took a bit longer. Hardest part was getting the module power wire up to battery in engine compartment. Would be nice if wire protector was included for going to flat connector at rear of car.



by:
2017 Ford Escape

The kit was pretty good, but I didn't use the cheesy butt splices, opting to use heat-shrink, waterproof ones. Instead of gluing the converter box on with the provided mounting tape, which doesn't last in my experience, I zip-tied it to the plastic hangers that hold the wire bundle leading to the left rear light assembly. Also, if I had it to do again, I'd check to see if suitable power for the powered converter box could be found at the fuse box in the right rear of the car--running the wire to the battery was a huge pain, and seems like overkill.

The instructions were missing a page. I was able to download a pdf, but it would have been nice if they had been complete.

Buy extra zip ties before you start. It takes a lit to secure the power wire.

Bottom line, this is a good kit. You won't regret getting this product.



by:

Got the mostly hidden trailer hitch . Even though it was a bit harder to install I definitely feel it was worth it. I feel it looks better than the factory models! The lighting install went well also. All directions were very clear.



by:
2017 Ford Escape

I love these plug and play wire harnesses . back in the day I had to splice into the factory wiring to wire up a 4 way flat plug. Today it is made easy. Came with good directions and easy to install.



by:

I ordered the hitch and electrical harness together. Both arrived the very next day in perfect condition. Installation was completed the next day with assistance of a neighbor to help hold up the hitch while attaching the bolts on each side. All the rest went smooth and the hitch looks great! Very pleased at this point!

  • Recommended Trailer Wiring Harness on a 2017 Ford Escape
    There are 2 T-connector wiring harnesses for your 2017 Ford Escape, parts # HM40524 and # C56320. Basically, they serve the same purpose but are made by different companies. Part # HM40524 is made by Hopkins and # C56320 is made by Curt. Between them both I recommend the Curt. Our installers here tend to have better luck with the Curt wiring products.

  • Parts Needed for Towing with a 2017 Ford Escape
    The Curt Trailer Hitch Receiver # C13186 is a confirmed fit for your 2017 Ford Escape but for the wiring harness you want the T-Connector part # C56320 instead of part # 118566 which fits a 2013-2016 Ford Escape. If you will be using this to tow then you also need a ball mount and hitch ball. One of the more popular options that we have is the Curt Class III Ball Mount with 2" Ball # C45036.

We haven't had the chance to install the Curt harness on a 2018 version as of yet, but since they are still the same generation everything should be in the same place. You can double check on your Escape to make sure. If you don't want to store the 4-Way in your hatch or have it hanging below your bumper I recommend the Mounting Bracket # 18144.

  • Does Power Wire of Trailer Wiring for 2018 Ford Escape Have to Run to Vehicle Battery
    Not all vehicles can handle the additional amperage draw of the trailer taillights on the vehicle taillight circuits. Those vehicles need setup that draws power from the battery. Some vehicles have higher rated circuits that can handle this, and others need to have the power drawn straight from the battery to protect the taillight circuits. Even if the circuit you have at the rear fuse box is more than capable for the trailer wiring harness part # C56320 bypassing it and running the battery...

    Based on my research your 2017 Ford Escape with the 2.0L engine has a towing weight capacity of 3,500 pounds if it's equipped with the Class II factory tow package or 2,000 pounds if it's not. If you are unsure if you have the tow package I recommend contacting your local Ford dealer with the vehicle's VIN and they should be able to tell you this.
