Wiring a trailer doesn’t have to mean cutting into factory wires. This Curt T-Connector harness simply plugs into the existing factory tow wiring using the built-in connector. Once it’s in place, just insert the included fuse into the inline holder and you’re ready to go. There’s no splicing or wire extending needed, which means fewer chances for mistakes and a much cleaner setup.
This harness is built to handle a solid power load, rated for 6 amps on running lights and 3 amps for brake and turn signals per side. That gives it the capacity to run trailer lights consistently without dimming or flicker. The powered converter keeps current steady so your trailer lighting signals stay bright and clear.
The 4-flat trailer connector provides standard running, brake, and turn light functions while keeping wiring neat and out of sight. The plug-in design uses the existing vehicle connections, so there’s no need to drill holes or route cables across panels. The result is a tidy install that looks like it came from the factory.
Behind the simple plug-in setup is a Curt circuit board that’s known for reliability. Its powered converter helps prevent overloads between vehicle and trailer circuits, keeping both systems safe. Once installed, it’s a dependable link that handles everyday towing with confidence.

The product seems good. The installation was easy.
Excellent service and shipping.
As described. The You tube instructions are very good.
Buying from etrailer is easy good price.
Does exactly what I wanted. Installation was a breeze. I replaced a failed box from another brand (much more expensive one too). Hopefully this one holds up longer.
The wiring harness couldn't be easier to install it's plug-and-play
Fits directly to the connector in the trunk. Easy plug and play. I then popped the tab in thefloor of the trunk and ran the wires thru to under neath. All clean and hidden.
Order was on time as listed.
I have not tested yet on how well it holds up or how well it works. Time will tell.
Ill give it a 4 as of now
It was a very good quality product and very simple to install
