Features to know about

Installs Without Cutting or Splicing: Plug-In T-Connector

Wiring a trailer can be tricky, but this Curt T-Connector Vehicle Wiring Harness with 4-Pole Flat Trailer Connector keeps things simple. It plugs right into the existing tail light wiring, so there’s no cutting or splicing needed. The connectors match up cleanly and lock in place for a solid, trouble-free setup.

Protects Your Vehicle’s Circuits: Powered Converter Design

Running trailer lights off your vehicle’s own circuits can overload them. This harness solves that problem with a powered converter that takes its power directly from the battery, not the tail lights. That means your car’s wiring stays protected and you still get full, reliable lighting on the trailer.

Keeps Trailer Lights Working Right: Works with LED Setups

LED trailer lights draw less current but can confuse some wiring systems. This harness handles that perfectly, delivering steady signals for turn, brake, and running lights. Whether your trailer has traditional bulbs or LEDs, everything functions just as it should.

Clean, Hidden Installation: 4-Flat Connector Ready to Use

Once installed, the 4-flat connector sits neatly at the back of the vehicle and plugs right into most trailers. It provides running light, turn signal, and brake light functions in one compact plug that’s easy to reach when you’re ready to tow.

I purchased before from etrailer. I was never disappointed.

by: Steve H 01/25/2017

The perfect fit and perfect price. Easy installation and I was able to do it myself in under an hour. The most time-consuming part, that wasn't even an issue, was fishing the powerline from the rear to the battery. I have not towed anything with it yet but I have hooked it up to my trailer and everything worked as expected. I'm very happy I found etrailer.com and will definitely use their website again

Easy install. A little bit annoying to run the wire to the battery, but a necessary evil with any kit. Works great!

I totally agree about the wire to the battery part. Maybe one day we wont have to :)

2002 Honda Civic

Installation took a few hours, but with time and patience it was fairly straight-forward. I installed this connector onto a 2002 Honda Civic, so the battery was on the passenger side and had to re-design based off the documentation that the thing came with. I would recommend getting a connector tester from Harbor Freight

2004 Honda Civic

This product is amazing! It took me only two hours to install the hitch and the wiring harness on my 2004 Honda Civic Hybrid. The plug in terminals take all the guesswork out of finding the right wires and the only mildly challenging task was running the power wire from the battery to the power module. The videos gave me the general sense of what to do...and it really was easy! I plan on towing a Yakima Rack and Roll with my kayak so I should be set to go. Thanks for a great product!

This unit worked for me at first and was easy to wire, but shorted out in under a year leaving me with no trailer lights

From customer service to the price with shipping, excellent. Please keep up the great work.

I bought this TRAILER Connector to replace the same unit that went bad after 7 years. Installation was easy.

by: Jeffrey 01/11/2019 One Year Later

The harness was super easy to install and works flawlessly. The hardest part is getting power to the trunk but i had already installed terminals back there which this seamlessly connected to.

Why Is a Power Wire Needed For a Trailer Wiring Harness On a 2002 Honda Civic
The power wire for a trailer wiring harness like the Curt T-Connector Vehicle Wiring Harness part # C56341 is needed on your 2002 Honda Civic because the vehicle's lighting circuits are not capable of handling the additional load a set of trailer lights would require. If you were to use a non powered trailer wiring harness you would likely short out the vehicle's lighting circuits. If you have not already made your mind up on a trailer hitch, I recommend using the Curt Trailer Hitch Receiver...

Trailer Hitch and Wiring Harness for 2003 Honda Civic Sedan
We do have a trailer hitch receiver that fits your 2003 Honda Civic, but it isn't the model you mentioned. Instead, your '03 Civic will need the Curt Trailer Hitch Receiver # C11204.

The correct parts for your Civic are: - Curt T-Connector Vehicle Wiring Harness # C56341 - Curt Drawbar # C45521 - Curt Class I and II Pin and Clip # F-4 - 1-7/8" Hitch Ball # A-80 or 2" Hitch Ball...

Parts Needed To Install a 7-Way and Trailer Brake Controller On a 2002 Honda Civic
You are able to just install a 4-way flat at this time and then later install the components needed for a 7-way and trailer brake controller. But it may be best to just do everything at once since you are going to have to run a power wire to the vehicle battery with both the 4-way and 7-way. First to determine which 4-way you need we need to know what body style you have. The coupe and hatchback version are going to use the 4-Way # C59236 while the sedan is going to use the 4-Way # C56341....
