Running wires or cutting into factory circuits can be intimidating, but this harness keeps it simple. The Curt T-Connector plugs in behind each tail light using factory connectors, so you get a solid connection without touching the vehicle’s original wiring. Once it’s in place, you’ll have a clean 4-flat trailer plug ready to go.
Trailer lights need steady power, and that’s where the included powered converter comes in. It delivers consistent current to the trailer for the stop, turn, and running light circuits. That means your trailer lighting stays synced and bright, even with LED tail lights or when towing after dark.
This harness is designed for vehicles without a factory tow package, so there’s no extra hardware or programming required. You’ll just need to run one power wire up to the battery, and everything else is plug-and-play. It’s a good fit for anyone adding trailer wiring for the first time.
The 4-pole flat connector gives you the standard trailer lighting functions—running lights, left and right turn signals, and brake lights—so you can hook up to most small and mid-size trailers. It’s a straightforward way to power lights for utility trailers, campers, or cargo haulers.

Great fit, I routed it my way all inside the vehicle for protection and longer lasting.
Very friendly and helpful customer serv ice
Will update after the installation but deliver was fast and simple
It was easy to install and connect
The Curt T-Connector is very easy to install. The video on the e-trailer website is a great help. E-trailer has fast shipping and always a fair price. I would recommend them.
Pretty easy to install. Plug & play & excellent how to video. Only bad part was doing it without a lift. Not much room under there.
Super easy install on my 2019 Edge Titanium. I found a model online and 3D printed a mount with PETG for the wiring connector. Really classy looking installation!
The harness design along with the videos on the website made installation in our 2022 Ford Edge very easy. Without the videos it would have been challenging to attempt to disassemble the tail lights and and install the harness without doing damage. The trailer lights work perfectly.
excellent hitch and wiring kit worked perfectly to interface with my Ford Edge.
Removing the tail light was difficult. One screw. Pulls off.
Had to add duct tape as shown to pull the tail lights free. Careful. The lights are expensive.

My husband and I have been dealing more and more with our own DIY car repairs -- thanks for this awesome duct tape idea! Glad to hear the wiring worked out well, too :) Thanks, Stacy
