Features to know about

Installs Without Cutting or Splicing: Plug-In T-Connector

Wiring a trailer doesn’t need to mean hacking into factory wires. This Curt T-Connector uses a plug-in design that connects directly to existing wiring. No cutting, no splicing—just plug it in and you’ve got a 4-flat trailer connector ready to go.

Works When the Vehicle Has No Tow Package: Powered Converter Included

If your vehicle didn’t come with a tow package, this harness takes care of that. It includes a powered converter that supplies the trailer lights with the proper signals and power levels, so everything functions correctly without overloading the vehicle’s lighting circuits.

Clean Look with Hidden Setup: Plug and Lead Design

This setup keeps things neat. The hidden plug-and-lead layout routes wiring through existing panels or trim, so most of it stays tucked away. You end up with a clean install that looks factory while still providing a sturdy connection point for your trailer wiring.

Covers the Basics for Small Trailers: 4-Flat Connector Output

Once installed, the harness gives you a standard 4-flat connector at the back—covering running lights, turn signals, and brake lights. That’s exactly what you need for towing small utility trailers, boats, or campers safely and legally.

Good instructions, easy installation, works as designed.

Great product. Our 2024 escape did not require any modifications, all mounting holes were in the correct location.



by:

The package I received had already been opened and was damaged. I'm guessing it was a return. I did go through everything and it appears that it is all there. Hopefully, there will be no issues with any of it.

Nice set-up and worked well

Installing this on my third vehicle. Hope it goes as smooth as the others. Great product.

Works as expected, easy to install and get towing.

awesome service



by:

The kit was basically pretty easy to install to get trailer lights for my 2024 Ford Escape PHEV. I would note that the instructions did not note the actual 12v battery hookup is under the spare tire carrier in the back. This actually made for a much shorter run for the 12 volt power for the modual.



by:

Worked great



by:

always easy to install and works well



by:

Everything worked out great for me and I didn’t have not one issue



by:

This is a project that you need to take your time.
Everything works great, but do not be in a rush.



by:

Easy install great instructions



by:

Although description says it fits 2026 Escape, wiring is for 2024 Escape. Minor modifications needed to install for 2026.



by:

I was able to install this myself quite simple with our 2024 Ford Escape Plug-in Hybrid since the 12 volt battery is in the back. A better description of how to unlock the original connectors would have been welcome information though.You really need this type of unit because the wiring in the new vehicles is such a small gauge of wire.



by:

Installation was exactly like the videos showed for our 2024 Ford Escape ST line. Pop off the trim, plug it into the wires going to the tail lights. set the grounding screw and put the trim back on. PLEASE NOTE- The Escape has a 12V outlet right where the harness goes. Rather than run a new wire from the battery, you can add a cigarette lighter adapter to the power cord and plug it in when needed, and unplug when not in use. WORKS GREAT!



by:

The process of installing this wiring harness was very easy. As long as you are comfortable with connecting spliced wire, then it doesn't get much easier. The video from eTrailer was spot on. The entire process took just about an hour and that's from beginning to clean up. Would definitely recommend, at least for the Ford hybrid Escape. Time to tackle my son's Bronco Sport;)



by:

Went in easy. Put the ground wire loop connector under one of the hold down bolts for the jack bracket. No self tapping screw needed for my SUV. Works as designed. Thanks.

  • Base Plate And Trailer Hitch For A 2024 Ford Escape Plug In Hybrid (PHEV)
    Hi Bob! We have you covered for both. For the base plate, I recommend the Roadmaster Direct-Connect Base Plate Kit - Removable Arms # RM77GR. They make the best base plate in the industry and are the ones to get. That said, do you already have tow bars? If they aren't Roadmaster, let me know what they are and I can see if we have something to match it. If you do not have a tow bar yet, I have the one I recommend below as well as the needed wiring: etrailer SD Non-Binding Tow Bar for Roadmaster...

  • Will etrailer Trailer Hitch Fit My 2024 Ford Escape Active

Will you be using the hitch for a bike rack, towing, or something else?

  • Recommended Wiring Harness for a 2025 Ford Escape PHEV
    Hey Dennis, welcome back. The Curt Powered Tail Light Converter item # C59236 will work for your 2025 Ford Escape PHEV.

I checked with Curt and took a look at our reviews to confirm that this harness will fit the PHEV models of the 2025 Escape. It's going to plug right into your tail light harness in the rear cargo area and connect directly to your battery. I do not have an installation video for the Curt item...

  • All Parts Needed to Flat Tow 2023 Ford Escape PHEV & Difference Between Wiring
    Hi Mike, So starting with the wiring, the T-Connector Vehicle Wiring Harness with 4-Pole Flat Trailer Connector # C55VV you mentioned isn't for flat towing, it's for towing a trailer behind your 2023 Ford Escape PHEV and goes to the rear of your vehicle. You were correct there are no kits that are direct connections so you will have to splice and use a kit that goes to the front of your Escape, the Roadmaster Diode 7-Wire to 6-Wire Flexo-Coil Wiring Kit # RM-15267. I know it's not what...

  • Recommended 4-Way Trailer Wiring Harness for a 2023 Ford Escape Hybrid
    Hey Andrew. The T-One Vehicle Wiring Harness item # TK57CR does fit the 2023 Ford Escape hybrid so long as you do not have the tow package. If you have the tow package you'll need the Curt item # C59ZV. These are the only two styles of connectors.

The Curt item # C59ZV plugs into a factory port behind the rear bumper on the driver's side. I linked a installation video below...

    Yes, it does! The etrailer Hitch item # e36RR has been confirmed to fit the 2024 Ford Edge. This hitch is custom fit and bolts to your Edge with included hardware.
