To see if this custom-fit item will work for you please tell us what vehicle you'll use it with.
Easily add a 4-way trailer connector with this custom-fit harness. The T-connector plugs into existing wiring - no cutting needed. Powered converter protects vehicle circuits and ensures consistent trailer lighting for safe towing in any conditions.
The vehicle's wiring harness is often behind a trim panel or under the cargo floor. Some vehicles may require removing interior panels or lifting carpeted sections to reach it, but once accessed, the harness installs easily with quick-splice connectors.
Plugging in a trailer shouldn't mean tearing into your vehicle's wiring. This custom-fit T-connector snaps directly into your factory wiring harness, so you can get your trailer lights up and running without any cutting or splicing. Just plug it in, and you're ready to tow.
A well-lit trailer is a safe trailer. This 4-way wiring harness keeps your trailer's brake lights, turn signals, and running lights powered and in sync with your vehicle. Whether you're hauling a boat to the lake or a camper to the mountains, your lights stay bright and visible.
Some vehicles can't handle the extra electrical load of trailer lights. The built-in powered converter draws power directly from your battery, ensuring a steady, protected current to your trailer while keeping your vehicle's circuits from overloading.
Towing means exposing your wiring to dirt, rain, and road grime. This harness features fully insulated wires and a sealed converter, helping to prevent shorts and corrosion. It's built to withstand the elements so you can tow with confidence in any weather.
No extra trips to the hardware store - this kit comes with everything you need. With fuses, zip ties, and connectors included, you can complete the installation without hunting down extra parts.

Hi everybody, Andy here with etrailer.com. Let's take a real quick look at this Curt T-Connector Vehicle Wiring Harness with 4-Pole Flat Trailer connector. Now, this harness has been designed specifically for your 2024 and newer Lincoln Nautilus. And on custom fit parts such as this harness, I do recommend taking advantage of our vehicle fit guide here at etrailer.com. Simply input the year, make, and model of your vehicle and our fit guide will confirm if this will work for you or if we have something comparable that will work for you. Now, this is going to give you a four-way flat trailer connector at the back of your vehicle to power your trailer signal lights.
This will also be compatible with five, six, and seven pole adapters, and those adapters are sold separately. This does come with a dust cap for the four-way flat connector to keep that plug connected from dirt, debris, moisture when it's not in use. And a well lit trailer, as you know, is going to be a safe trailer. And so this four-way wiring harness is going to keep your trailer's brake lights, turn signals, and running lights powered and in sync with your vehicle. Whether you're hauling a boat to the lake or a camper to the mountains, your lights are gonna stay bright and visible.
The custom fit T-connectors are going to snap directly into your factory's wiring harness, so you're gonna be able to get your trailer lights up and running without any cutting or splicing. You're just going to plug these in and you'll be ready to tow. Now, the vehicle's wiring harness is often behind a trim panel or under the cargo floor. Some vehicles may require removing interior panels or lifting carpeted sections to reach it, but once you access it, the harness is going to install easily with these quick connectors, as you can see here. And again, these are custom fit for your vehicles.
The included instructions will guide you through the installation process. Now, some vehicles can't handle the extra load of the trailer lights, and so the built-in powered converter that you see right here is going to draw power directly from your vehicle's battery, and that's going to ensure a steady, protected current to your trailer while keeping your vehicle circuits from overloading. So this kit's gonna come with everything that you need to get this installed into place. You're gonna get the harness, you're gonna get wiring, this is going to run to your vehicle's battery, you're gonna get a fuse holder, and then you're going to get cable ties to secure excess wiring, butt connectors, a fuse, and as I said, instructions to guide you through that installation process. So everything that you're gonna need to get this into place.
Now, it is also recommended that you use a small amount of dielectric grease on all of your electrical connections, like the plugs on your vehicle and the four pole connector itself. That grease is designed to help prevent electrical failures caused by corrosion and moisture. So on your screen, I am including our model number for that grease. You can just take that model number, pop it in the search field of our website, that will take you to that grease, and you can add that to your order. Now, once you get this installed into place, we would love to hear back from you regarding how the installation went, and also regarding your experience using this wiring harness. So when you get some time, drop us a comment on this product page and let us know your experience in getting this harness into place and using it and send us some photos of it in action as well. We'd love to see it. Well, that's gonna wrap up our look today. I do hope that our time together has been helpful for you. Again, my name is Andy. Thank you for joining me.
