  • Powered Converter Protection: Built-in module safeguards vehicle circuits from trailer load.

Features to know about

Installs Cleanly Without Cutting Wires: Plug-In T-Connector Design

Wiring up for towing doesn’t have to mean cutting into factory wires. The Curt T-Connector Vehicle Wiring Harness with 4-Pole Flat Trailer Connector plugs right into the existing tow-package port, giving you a solid connection for trailer lights without any splicing. It’s the straightforward plug-and-play option for getting a working 4-flat at the rear of your vehicle.

Ready for Trailer Lighting Basics: 4-Flat Connection

Once installed, the 4-flat connector provides the standard lighting signals—running lights, turn signals, and brake lights—so your trailer lights up exactly when it should. It’s the basic setup that covers most small and midsize trailers for safe, visible towing.

Powered Converter Keeps Signals Reliable: Built-In Power Protection

This harness includes a powered converter that draws power directly from the battery instead of your vehicle’s light circuits. That helps protect sensitive electronics from overload and ensures your trailer lights stay bright and consistent even when fully loaded.

Expands Easily for More Trailer Types: Works with Adapters

If you need to tow a trailer that uses a 7-way plug, you can connect an adapter such as part #37185 to this 4-flat. That lets you expand to a 7-pole connection when needed, giving you flexibility for different trailers without rewiring the whole setup.

Received both hitch and wiring. Probably less than one hour, taking my time, to install everything. The wiring came with all fuses (30 amp) needed for the four pin connection. No need to have it installed at a shop. Pretty straight forward.

Nice job, Michael! Glad to hear your install went well!

Easy peasy. Once we found the correct angle to simply PLUG the harness into the Honda plug connection it was easy. Then we used an existing part of the car to attach the ground wire to, and had to find the correct nut to secure the wire with. The hitch was even easier with 2 people installing it. Also my neighbor has a impact gun so that thing ain't going nowhere.

Here’s a polished version that keeps the enthusiasm:

Absolutely perfect kit! Everything was the exact fit needed for my 2023 Honda Pilot TrailSport, and it came with all three fuses as well. The video instructions on the product detail page are amazing... clear, detailed, and incredibly easy to follow. Between the fit, the completeness of the kit, the price, and the excellent directions, I couldn’t have asked for anything better. Highly recommended!

Great product great price.i bought a honda with a trailer hitch from the factory but they dont supply any wiring. Its a $300 add on from honda. I couldnt be happier.

Love this product and the ease of installation. I wish every product I bought worked as well as this one. 5 stars for this one, I’d give more stars if I could!

Etrailer is awesome! The product we purchased was easy to order and came quickly. The Curt T connector came with easy to read and understand instructions PLUS ALL PARTS AND FUSES NEEDED FOR THE JOB!!!! We will definitely be ordering from them again. I could only give 5 stars but they definitely are a 10.

The wiring harness I purchased was great just like everyone I have ever purchased. They are quite easy to install and the video helps with a lot of great suggestions. My only concern was the fuses needed to make the harness work. The written instructions and the video were different. My suggestion is to look at what type fuses your vehicle uses before you purchase so you get the proper fuses the first time. I am very pleased with my purchase.
by:
I worried about the installation far longer than it actually took to install. Much encouraged by Josh, who was the person I dealt with. Thank you. Great video. MUCH LESS EXPENSIVE than the dealership installation as an accessory.

The harness plugged right in , added the car fuses to the car fuse box and put all the panels back together and the project was complete.

Easy install.

Install was easy. I used it with a set of lights attached to a cargo carrier. I like being able to roll it up inside the vehicle to avoid corrosion. I just run it out under the back hatch when we use it. I had to install a fuse to activate the trailering lights, on our vehicle. Videos available to follow process. Will by another for our next vehicle.

Very disappointed, the incorrect part was shipped making me unable to tow a trailer for a trip we had planned for the holiday. I ordered part number c48zv for a 2025 and received a 56519 for a 2023-2024.

The # C48ZV and the 56519 are the same exact part. The C48ZV is our part number for it. The harness fits all models of the 2023, 2024 and 2025 Honda Pilot per Curt, so what you have will work perfectly for you!

Do you have a question about this Custom Fit Vehicle Wiring?
  • Recommended Trailer Hitch For A 2025 Honda Pilot Elite
    Hello Hoan, thanks for reaching out. I double checked with the manufacturer, and they confirmed that yes, the etrailer Class 3 Hitch # e27KR will indeed fit the 2025 Honda Pilot Elite. It will be a no drill install and you will not need to cut any of the underbody panels. Keep in mind that the hitch will fit with a mini spare tire stowed under the vehicle but does not fit with a full-size spare. Also, the receiver can interfere with the hands-free liftgate sensor. In most cases, the sensor...

  • Most Economical Trailer Hitch Receiver and Wiring Harness For a 2023 Honda Pilot Touring
    Our etrailer Trailer Hitch Receiver # e27KR you found is our most economical custom fit receiver for your 2023 Honda Pilot Touring edition. For the wiring you can select from either the 4-Way # C48ZV or the 7-Way # C35ZV depending on the types of trailers you will be towing. If you have a trailer with a 7-way you are also most likely going to need a Trailer Brake Controller # 39510 along with the Wiring # 20127 to connect it. This is one of our most economical and reliable proportional...

  • 2026 Honda Pilot Hitch, Hands Free Liftgate Sensor Relocation, and Wiring Options
    Good day! Yes, there is a sensor relocation kit available for the hands free liftgate on your 2026 Honda Pilot, but we do not carry it. It is an OEM Honda accessory available through your local Honda dealer under part 08L91-TG7-100C. That kit is designed specifically to relocate the motion sensor so it continues to work with a trailer hitch installed. It is not tied to a specific aftermarket hitch, so you can use it with the hitch I recommend below. My favorite option for your Pilot is...

  • Recommended Complete Towing Setup for a 2025 Honda Pilot EX-L
    Hey Tim, are you moving to Texas? I've been to Texas a few times, and have always enjoyed it! To tow your U-Haul cube you will just need a hitch like the etrailer Trailer Hitch Receiver # e27KR, a wiring harness # C48ZV, and a ball mount # e67DR. With this harness, and the 4-way on the trailer, you'll have lights so you can safely make the trek to Texas. Feel free to let us know how that goes, and if you have any other questions don't hesitate to leave a comment!

  • What Fuses Will I Need For Curt T-Connector C48ZV To Work On 2026 Honda Pilot?
    Hello Greg, thanks for reaching out. The Curt T-Connector # C48ZV is the correct fit for your 2026 Honda Pilot Elite. Not all vehicles come with the needed fuses though, so that will definitely be something you want to check. The fuse box is easily accessible inside the engine compartment. There needs to be a 30 amp fuse in location 7, and a 20 amp fuse in location 12. I've included a screenshot from the instructions that will point you in the right direction. Hope this helps.

  • Troubleshooting Curt Trailer Wiring Harness With No Power
    Hi Mike; I would start by double-checking the ground connection on the Curt Wiring Harness # C48ZV. Make sure it's securely attached to a clean, bare metal surface. I would also unplug the factory connector and plug it back in to make sure everything is seated properly. If that doesn't help, use a circuit tester like # PTW2993 to check for power going into and coming out of the converter box. If there's no power going in, the problem is on the vehicle side. If you have power going in but...

  • Do I Need Additional Fuses for the Main Fuse Box on a 2024 Honda Pilot to Power a Wiring Harness?
    Yes, it is! Honda and other manufacture's like to leave the fuses out of new vehicles that do not come with a functional towing package to save on costs. You can verify if you're missing the fuses by checking your fuse box but I am pretty sure they won't be there. I took a look at your owner's manual and you'll want to look at fuses 7 and 12 in your main fuse box. The Curt T-Connector Vehicle Wiring Harness with 4-Pole Flat Trailer Connector item # C48ZV only comes with the fuse necessary...

  • Hitch and Wiring Recommendation for a 2025 Honda Pilot Black Edition
    Hey Gregory, thanks for reaching out! I recommend picking up the etrailer Trailer Hitch Receiver # e27KR and the Curt T-Connector Vehicle Wiring Harness # C48ZV for your 2025 Honda Pilot. At this point in time we haven't tested out the hands-free liftgate feature on a 2025 Pilot so I can't guarantee that it will still work with any of our hitches, but it sits back far enough you should be able to kick to the left or right of the hitch receiver for the sensors to pick up your foot motion.

  • Recommended Hitch for a 2027 Honda Pilot that Works w/a Vertical Bike Rack
    There sure is Jenny and congrats on your new SUV! To add a hitch to your 2027 Honda Pilot that works with a vertical bike rack, I recommend the Blue Ox item # blu35vj. This hitch is custom fit and comes with all hardware necessary to complete the installation. The Blue Ox item # blu35vj is a class III hitch with a 2" receiver that has a 6,000 lbs towing capacity and a maximum tongue weight of 600 lbs. It'll work great for your vertical bike rack and give you the option to tow a decent...

  • What Do I Need To Get A 7 Pole Connection On My 2024 Honda Pilot?
    Hey Keith, The right wiring harness for your 2024 Pilot is the # C48ZV. This is a simple plug and play installation that would get you that 4 flat connection in the rear. I attached a installation video of this on a 2024 Pilot for you. Since your trailer is a 7 way connection you are going to want to go with an adapter like # 37185. This is going to plug in to the 4 flat on the vehicle and allow you to have a 7 pole connection at the rear for your trailer to plug into. I have attached...

  • Comparing etrailer and Curt Hitch for 2025 Honda Pilot
    Hey Daniel! The etrailer # e27KR and Curt # C22HR look so similar because they share the same design. The only real difference between the two is the finish. I prefer our own etrailer finish which is a matte black. This gives it an OEM appearance and also helps hide dirt and scratches. If you prefer a glossy finish then the Curt is the way to go. Do you plan on towing? If so, you will also need wiring and a ball mount. If you want to add a 4-way you can use the Curt # C48ZV or for a 7-way...

  • Trailer Wiring Harness For 2025 Honda Pilot
    Hi Ed, We do indeed have trailer wiring harnesses that fit your 2025 Honda Pilot. I went ahead and checked directly with the manufacturer for you and verified there are two options - a 4-way and 7-way: - 4-Way: Curt T-Connector Vehicle Wiring Harness # C48ZV - 7-Way: Curt T-Connector Vehicle Wiring Harness # C35ZV Use the 7-way if you are towing a trailer with electric brakes and have a brake controller, but if your trailer doesn't have electric brakes and you just need the harness...

  • Is There a Trailer Hitch Receiver Compatible With Hands Free Liftgate On 2025 Honda Pilot?
    While we have not personally tested the hands free liftgate on a 2025 Honda Pilot Touring we have received reviews on the Curt Trailer Hitch Receiver # C22HR that it was still operational. Do understand as I found out on my Acura RDX that the area you have to kick your foot will be reduced and you are most likely going to have to kick your foot closer to the rear fascia then before. We have either a 4-Way # C48ZV or 7-Way # C35ZV wiring kit depending on what size trailer you are going...

This is a class III hitch with a 2" receiver that has a 6,000 lbs towing capacity and a 900 lbs maximum tongue weight. I have attached an installation video to help you get it installed. If you are planning on towing you will also need a wiring harness item # C48ZV for a 4-Way or item # C35ZV for a 7-Way and a ball mount...

    If your 2023 Honda Pilot doesn't have the tow package port in the storage cubby area on the driver's side that is needed for the plug-in Curt T-Connector # C48ZV then there isn't another plug-in option, you'd have to use the hardwired Curt Powered Tail Light Converter w/ 4-Way Flat Trailer Connector # C59496. You may want to check just to make sure so you don't have to do more wiring than is necessary. The cut out below is from the instructions of the # C48ZV for where to find the white...

  • Is Mounting Bracket Needed For Curt 4-Way on 2024 Honda Pilot
    Thanks for the purchases Cathy, and the quick answer is nope, a mounting bracket is not needed at all for your 2024 Honda Pilot for the Curt T-Connector Vehicle Wiring Harness with 4-Pole Flat Trailer Connector # C48ZV. Pretty simple reason why is the # C48ZV will actually mount right in the rear storage area/hatch of your '24 Pilot and you'll only take it out of there when you want to use the 4-way. I like the fact it stores in the hitch because the 4-way will stay cleaner and won't get...

    Hey Sal, The correct Curt trailer hitch for a 2024 Honda Pilot would be the Curt Class 3 Trailer Hitch # C22HR (13472). The 13146 is a fit for 2016 - 2022 year models. If you plan on towing a trailer then you'll want to pick up the Curt T-Connector Vehicle Wiring Harness with 4-Pole Flat Trailer Connector # C48ZV to transfer your light signals to the trailer.
