Wiring for towing can be intimidating when you’re not starting with a factory tow package. The Curt T-Connector Vehicle Wiring Harness with 7-Way Trailer Connector (part #C35ZV) makes it simple by plugging directly into the existing vehicle connector in the rear cargo area. There’s no cutting or splicing—just plug it in and it’s ready to power your trailer lights and accessories. It’s a clean, direct hookup that takes the stress out of DIY installs.
If you’re planning to tow something heavier or run a brake controller, this harness gives you the proper 7-blade trailer connection. It supports electric trailer brakes, turn signals, reverse lights, and auxiliary power so you can tow safely and keep your setup fully functional. Once installed, it pairs easily with brake controllers like the Redarc Tow-Pro Liberty for proportional braking control.
Vehicles without a tow package often lack the fuse provisions needed to energize trailer wiring. This harness comes with the fuses necessary to power the circuit, saving you from tracking down missing components. Everything is already matched to work with the included connectors and wiring for a straightforward installation that doesn’t leave you guessing.
Even with the new wiring installed, factory convenience features stay functional. The design of the Curt T-Connector doesn’t interfere with hands-free liftgate sensors, so you can still use your foot-activated liftgate as intended after wiring in your trailer connection. It keeps towing capability and everyday usability working side by side.

Hello everybody, this is Jeff at etrailer.com. Today we're gonna take a look at the CURT T Connector Vehicle Wiring Harness with the seven-way blade trailer connector. Now this is a custom fit part, it is designed to fit the 2023 and newer Honda Pilot vehicles. And on a custom fit part like this, I do like to recommend for you to go to our website, use the fit guide, put in your year and model vehicle, and it'll show if this will work for your application. Now this part here is gonna provide this seven way blade style trailer connector at the back of your vehicle to power your trailer's signal lights. It will include everything I have laid out here on the table.
It includes the wiring harness, seven way trailer connector, a little tube of silicone when you do your installation, has a double face pad that'll attach to this converter box. When you attach that down. Comes with a ground screw if you need to make your own ground. Comes with three different variety of fuses to go in the fuse box to make this operational. Comes with some cable ties, take up any slack in the wiring, and a nice set of instructions that'll describe how this all goes together.
Now this part'll connect quickly and easily. There's no cutting or splicing of wires. All you have to do is locate the connection point, which is behind the driver's side rear access panel. In the instructions it will show you with pictures where it's located. You basically plug in this connector right here to the factory white connector on the vehicle, ground your white wire if there's a nearby ground you can use, or as we said, it comes with a grounding screw to make your own.
And then you install these fuses into your engine compartment fuse box. It does include this box right here. This is a tail powered taillight converter. This is to ensure that your vehicle's wiring will match that of your trailer. It is a powered module.
It connects directly to the battery to avoid overloading your vehicle's electrical system. And this box is constructed using SMT, Surface Mount Technology for consistent, reliable performance. It's gonna maximize the trailer light yield and intensity while producing minimal heat. Does ensure superior operation in rough road conditions. The maximum amperage on this kit, the stop and turn lights, is three amps per circuit. The tail lights is six amps per circuit. But that's gonna do it for a look at this CURT T Connector Vehicle Wiring Harness with the seven-way blade trailer connector.

Awesome
Just what I needed.
Wrong fuses & no black silicone. Great besides that
Curt obviously does not care about the quality of their product they sell, I would recommend a different brand. E-Trailor was very good with their responsiblity in this purchase
Timely delivery and incredibly easy to install!
7-way wiring harness was easy for my fiancé and his sons to install.
The wiring harness was easy to install and seems like good quality. Only complaints would be that I needed much longer zip ties than the kit came with, and the main 30amp fuse is the wrong (physical) size for my 2025 Honda Pilot. Neither of these are big issues since fuses are cheap and I have plenty of my own zip ties, all of the important stuff in the kit does exactly what it should.
Everything was good except the 30 amp fuse it to big to fit. I had to order a different fuse to complete the install. This is an issue from Curt not eTrailer. Just be aware if you are doing a self install.
The harness package came open with the wrong fuse.
This harness requires a 90 degree wire end at the hitch to mount to factory mount.
Clean wiring and the right concept but does not mount up at all like a factory unit. You have to custom fit it. Mines is still there dangling
Perfect fit - exactly what I needed!!
Came on time. Packaged well.
Was able to install within an hour without issues. Do need a separate bracket to mount plug so keep that in mind.
This kit would have gotten 5 stars had it come with a bracket for mounting the 7 pin.
This harness was an exact plug and play. Several videos are posted online that show how to install the harness. All of the fuses were included and it only took about an hour to install. The dashboard lit up like a Christmas tree after turning on the vehicle. I drove it around for a minute and they all shut off. The computer on the 2025 Pilot doesn’t like the install without a reset. I’ve had no issues and all the lights worked on the trailer.
Instructions are difficult to understand. I’m comfortable working on electrical automotive stuff and I find this daunting
Everything was easy to install—only the 30A fuse was the wrong size.
Additionally, after installation, the entire vehicle system goes into limp mode; however, this clears up after a few starts and a short drive.
The harness itself was not a problem. The directions were oddish and most of the pictures too dark to discern there wasn’t a bracket to mount the plug to the car. After my neighbor ran most of the harness through the car I tried, unsuccessfully, to install a bracket. Finally I gave up and took it too the installer that I’ve used for hitches and wiring before. In 30 minutes he modified two brackets and had it installed.
So much for my DIY skills.
Instructions were very poorly printed and the pictures were not clear and distinct

If you go to our product page, there's a link to a pdf copy of the instructions. Very clear print and photos. There's also a link to an install video that you might find helpful!
Electrically everything was great. Mechanically... not so much. As other reviewers have said - if you have the factory hitch then the 7 pin plug can't be mounted with the provided hardware because the hitch attachment bar is in the way. You need a right angle electrical plug, which apparently only comes in the Honda factory kit. Curt needs a right angle connector too in order to make this 5 stars.
