Running a new power wire to the battery takes time, but this harness skips all that. The Tekonsha T-One Vehicle Wiring Harness with 4-Pole Flat Trailer Connector plugs into the factory tail light connectors and pulls power directly from them. That means no extra power wire to route under the vehicle. Just plug in both sides and the 4-flat is ready for your trailer lights.
Once connected, the 4-flat trailer plug delivers the basics—running lights, brake lights, and turn signals—so your trailer stays visible and street legal. It’s a simple, proven setup that works with most small trailers and keeps things easy when you hook up for a trip.
The harness tucks neatly behind trim panels and connects through existing tail light plugs, keeping the install hidden and protected. There’s no cutting or splicing, so everything looks factory once it’s done. It’s a clean finish that won’t interfere with other wiring or body panels.
Because it’s plug-and-play, you don’t need wiring experience to install it. The connectors match the vehicle’s existing plugs, so it’s easy to see exactly where everything goes. Most folks can handle the install in their driveway with basic tools and be towing the same afternoon.

Again great service great website helpful videos recommended to all my friends
Easy install 15 minutes and it was d one.
Works perfectly only drawback wires need to be a little longer.
Good product. Easy to install and the only issue I had was running the wires from one side to the other. Taking my time was about a 20 minute project.
Great product! Fast Shipping! Installed complete hitch and wire set in 40 minutes. Saved me 400.00 from taking it elsewhere.

Would do business with them again.
Great staff and easy to
Work with.
Work exactly like the videos show very easy to install done 20 min.
excellent if I can ever get it installed. The weather here in St. Louis area. If Nick as around tell him that I met his wife, Angie at the hospital yesterday, I had hip surgery and she was my nurse.
Ordering was easy. Product as ordered. Order came within a week. Would recommend this company. Was told by car company is would cost about $300.00 to put harness on. It will cost approx. $45.00 to do so by using this product.
It was a very nice hitch. The installation was very smooth and fit great. deleivery time exceeded my expectations, I will recommend etrailer to all my friends.
I watched the video on your website and it was very simply explained. Installation was a breeze. Product was exactly as seen in video. A+ is how I rate this product.
Your product is almost excellent. The drawback is that the wire going over to the left side is almost too short. And that's after I ran it along the inside seal (underneath) of the rear hatch (works really well) to shorten the distance. If I had run it under the car it would have been too short. Other than that it works really well and is an easy product to install.
I purchased this trailer wiring harness for my 2010 Dodge Journey. Delivery was very quick and it was extremely easy to install, the directions clear, and it worked just as it should. A big plus is it saved me well over $100.00 as opposed to buying a "factory" harness.
this product work really good. the only bad thing is. when i went to install it. the wire was on the short end to reach over to the other light. but i was able to cut a few of the zip ties and had plenty of wire then. it also was very easy to still.
I called customer service & gave them the part #, and within a very short period of time the wiring harness was on its way. Received it fast & was the correct product, the install took less then 15 minutes. I will buy from & recommend etrailer.com in the future.
Easy to install, The green wire (passenger side) should be a foot longer. I couldn't running it through the frame like i did the 4-wire connector. Other then that works just like it should, cant ask for more then that.
E-Trailer did exactly what I had expected. They delivered a good product, at a good price, and on time. In addition to that they did something very unexpected, they provided a very well put together video that showed me how to install the kit with minimal issues, and they contacted me various times through out the ordering process to insure I received what I expected. In the future I will make it a point to insist that people contact E-Trailer for their hitch and trailer needs.
wow i orderd on line 6-18 320 in the morning.got a email at 4:20 confirming order another email at 5:24 pieces available ready to ship. on same day 6-18 at 1:37 email pieces shipped. wow monday afternoon there in the mailbox.im not talking a week im talking 6-20 monday people and they are the right parts for my car.im just sorry etrailer that i orderd the things from uhaul first. the hitch from them was 5 days wiring was 7 days an was a universal wiring not a custom fit.again sorry etrailer next time i will go right to you great job thank you andy
I purchased this for a 2010 Dodge Journey, and I have to say the installation was easy enough and it worked great the one and only time I had to use it. I think a little more planning on my part would have made running the wire through the bumper channel a lot simpler but I have no complaints. Definitely worth the money.
Install of the lighting wiring was a breeze with this kit. Install video reflects what is required to get this installed well. Fishing the wires as shown in the video rewards you with a well protected and professional look, with nothing showing except the 4 wire connector for the trailer.
Had to remove one wire tie to lengthen the green wire running to the passenger side. Removing another would give you another 6"-8" if you routed the wire differently and needed the additional length. Connectors clicked right into the factory wiring on my 2010 Journey and felt secure.
Perfect fix for my 2010 Dodge Journey R/T. Factory hook-up went bad and was too expensive for me to repair, and I only pull trailers with a 4 flat anyway so I just threw this in and it works well.
