Wiring a trailer can be messy if you have to splice into factory wires, but this harness keeps it clean. The Curt T-Connector Vehicle Wiring Harness with 4-Pole Flat Trailer Connector plugs straight into existing factory connectors. No wire cutting, no guesswork—just plug it in and it’s ready to go.
Some vehicles can’t power trailer lights directly through the tail light wiring. This harness includes a powered converter that draws power from the battery instead of the vehicle’s lighting system. That keeps sensitive electronics protected while giving your trailer bright, consistent lights every time.
The built-in 4-flat connector provides all the essential lighting functions—running lights, turn signals, and brake lights—so your trailer stays road-legal and visible. It’s the standard connection most small and mid-size trailers use.
Even if your vehicle didn’t come with a tow package, you can still add trailer lighting easily. This kit is designed to work on vehicles without a factory tow setup, so everything you need for proper trailer light operation is right here.

I will be filing a chargeback because no insurance was made on this order which was stolen off my porch.
Couldn’t be made any better. Very easy to install. Very happy with it.

The wiring harness for the hitch is not working out. I have brought the car in twice for wiring problems to our Nissan dealer who installed the hitch. They had to detach the wiring harness because it was interfering with the turn signal lights on the car. Two different technicians in separate trip attempted to fix the problem and they were not able to accomplish the task. I have a great hitch but no lights for the trailer. Yes, I supplied the technicians with all the information I had downloaded what was included with the product, and other information that was sent to me.
Website provided great installation dir ections
I received my order in 3 day not in 6 day thank you very much.
Like your tracking system and prompt sh ipment
Nice kit. Easy to install! Thanks Etrai ler.
Arrived on time and in perfect condition. Fits my 2022 Rogue Sport SL AWD perfectly and relatively easy to install. Light test at plug shows all A-OK.
Sent multiple surveys back to etrailer. Thanks for your assistance.
The quality of the product is great however the cables are just too short. I'm and electrician and like to dress my cables and I just couldn't make it work without extending the jumper going to the passenger side light. Add 12" and you have something...
I have not any problems with your product..Thank you for your great customer service and followup!

Just wanted you to know that I am absolutely delighted with my hutch..no issues and just as sturdy as the first day o put it on.Great product and appreciate the follow-up.. and communication. Ps Im a handy woman who installed my own hitch. !
The wiring to the right taillight is a few inches too short this time compared to the last one I purchased. I will have to add more wire for it to connect properly. Same with the wires going to the black box. They are shorter then the last one. I was at least able to hang that in a different location.

What year Rogue were you installing this in? I can take a look and see if there was something different about that specific year. Is the harness working well for you at least?
