Features to Know About

Straightforward Installation, But Plan for Access

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.

No Cutting or Splicing Needed: Custom-Fit T-Connector

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.

Reliable Trailer Lighting for Every Trip: Powers Brake, Turn, and Running Lights

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.

Prevents Overloaded Circuits: Powered Converter for Safe Towing

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.

Keep Wires in Check: Fully Insulated and Weather-Resistant

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.

Everything You Need for a Clean Install: Complete Kit Included

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.

Video Transcript for Review of CURT Custom Fit Vehicle Wiring - T Connector Vehicle Wiring Harness 4 Pole Flat - C73DQ

Hi, everybody, Andy here with etrailer. Let's take a 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 2025 and newer Nissan Murano, 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 harness will work for you, or if we have something comparable that will work for you. So, as you know, a well-lit trailer is going to be a safe trailer, and this 4-way wiring harness is gonna keep your trailer's brake lights, turn signals and running lights powered and in sync with your vehicle. So, whether you're hauling a boat to the lake or a camper to the mountains, your lights are gonna stay bright and visible.

Now, plugging in a trailer shouldn't mean tearing into your vehicle's wiring, so this custom-fit T-connector's gonna 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 gonna plug it in, and you're gonna be ready to go. Now, the wiring harness on your vehicle is typically behind like 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 this connector.

Instructions are going to be included with this harness to guide you through that installation process. Now, some vehicles can't handle the extra electrical load of trailer lights, so this built-in powered converter is going to draw power directly from your battery. This is going to ensure a steady, protected current to your trailer, while keeping your vehicle's circuits from overloading. And towing usually means exposing your wiring to dirt, rain, and road grime. This harness does feature fully insulated wires and a sealed converter, so that's gonna help prevent shorts and corrosion.

This is built to withstand the elements, so you're gonna be able to tow with confidence in any weather. This does include everything that you see here. And it is also recommended that you pick up a small amount of dielectric grease and apply that on all of your electrical connections, like the plug on the vehicle end, and the 4-pole flat connector itself. That grease is designed to help prevent electrical failures caused by corrosion and moisture. So, on your screen, I am including our item number for that grease.

You can just take that item number and pop it in the search field of our website. That will take you to the grease, and you can add that to your order if you so desire. If you happen to have any other questions, whether it's about this harness or anything else that we have here at etrailer, don't hesitate to reach out to us, 'cause ultimately, we wanna make sure that you're getting exactly what you need. Well, again, my name is Andy. Thank you for joining me.
