Say goodbye to lengthy and complicated wiring setups with the Curt T-Connector Vehicle Wiring Harness. This custom-fit harness plugs directly into your vehicle's OEM tow package port without any cutting, splicing, or tapping of wires. It's as straightforward as plug-and-play, ensuring a fast and hassle-free setup every time you need it.
Whether your trailer has a 5-pole, 6-pole, or 7-pole configuration, this 4-way flat trailer connector has you covered. With compatibility with various adapters, you'll have the flexibility to tow different types of trailers without needing multiple connectors or adapters. This versatility comes in handy whenever you need to switch between different trailer types.
Protect your electric connections from the elements with the included dust cap, ensuring long-lasting durability of the 4-way flat trailer connector. To add an extra layer of protection against corrosion, it's recommended to use a small amount of grease on all electrical connections. This simple step can prolong the lifespan of your harness, keeping it in top-notch condition even in harsh conditions.
This wiring harness is custom-made to match the factory tow package of your vehicle. It securely plugs into the tow package wiring harness located behind the rear bumper, ensuring an optimal and secure fit. This custom design takes the guesswork out of the installation process, offering peace of mind knowing that your setup is just like the manufacturer intended.
Ensure your trailer's signal lights operate flawlessly with the Curt wiring harness. By providing a reliable 4-way flat connection at the back of your vehicle, your trailer’s lights will consistently communicate with your vehicle's systems. Whether you’re signaling a turn or stopping, you can do so with confidence that your trailer will mirror your vehicle's actions.

Wasnt what i needed. Postage to return was more than what it was worth to send back. Its a great paperweight or if i jam it under the door its an okay doorstop
Haven’t installed yet but did watch the video. Looks like a job one ot two can do pretty easily!!!
Unplugged the cap off the factory 7 pin round connector and inserted the new harness, fit perfectly. Tested the connections and all indications using a tester was spot on. This was a fantastic converter for my wiring. 10 minutes and I was done.
This was a quarter of the price that Jeep wanted to sell it to me for and with some personal modifications/additional wiring I now have two versatile means of hooking up my trailer lights!
Excellent product and very straightforward to install. Opted for the Curt T-Connector C55515 and will have my dealer flash computer to recognize new configuration. Already used hitch with trailer to haul several heavy items up to about 2000lbs with no trouble whatsoever. Should have got this years ago!
Fast shipping, easy install, product as described. The only complaint was the need to take the vehicle (2014 Jeep Grand Cherokee) to dealer for ECU flash. I know this is not Etrailer's fault so not knocking them. I just hope to save other people time in the future if they think they are just able to plug in and tow.

8/02/2016 Update - replaced the 2014 Grand Cherokee with a 2016 Grand Cherokee, forced dealer to swap the hitch and wiring from old jeep to new jeep as part of the deal. Item still working as described, no complaints.
Perfect fit, exactly what I needed.
avalanche owners,easy too install i highly suggest when installing pull the cable through the hitch its open at the end less wire being exposed,(this is from my experience) other than that i am very happy with an troop,Patrick B,an everyone at etrailer.com provided great costumer service i will be buying from them soon.

Still working after the harsh new England weather we had still works I highly recommend there products also I willing be putting in an order for a new Chevy light up logo so get ready
I was not aware at the time i purchased this item that it was not what i needed. The page told me i needed this item to complete my set up so i bought it. little did i know that my vehicle does not have a factory wiring harness so what i bought was useless. I am going to have to return this item. The page should also make it more clear of what you may need before you purchase something and you wait almost 2 weeks for it to arrive. I had to order what i needed else ware to be here when I need it to be.

Thank you for your review. The 2019 Dodge Durango does need a factory towing package to use this wiring harness. Since the 2019 Dodge Durango does not have the factory towing package you will need part Curt T-Connector Vehicle Wiring Harness with 4-Pole Flat Trailer Connector part C56336.

Question for you please. The hitch itself has been great, but I can't get the wiring harness for the lights to work on the trailer. I'm reading different things online, sounds like my Grand Cherokee may have to be programmed for the lights to work? Are you familiar with that? Is that the case?
Thanks in advance!
I chose the Draw tight Max Frame Trailer Hitch for its known quality, i like it comes powder coated to reduce unsightly rust and to keep that fresh look.
I chose the this hitch for my all around light and heavy duty needs.
The Draw Tight Ball Mount is a quality enhancement to this hitch.
I chose the 2" chrome ball for its quality and appearance.
The Curt C55515 wire connector was the best choice for my lighting needs.
Decent looking product. Would have been even better if it worked as advertised. Does not plug into my 2006 Ranger with tow package. Etrailer.com offered to refund the purchase price minus the original shipping cost, plus I had to foot the bill to ship it back. It would have cost more than it's worth. No thanks, I'll just use the pigtail and hard wire it.
Etrailer customer service was very prompt in responding, not that it did me any good.
Works perfectly! Pulled the cover off the existing plug on my 2014 Grand Cherokee (up under the rear of the vehicle) and this plugged right in.
NOTE: You may have to have the computer flashed by the dealer to enable trailer lighting. This cost me about $45 at a local Dodge dealer.
The connector was as described ,no splice and simple. Also i ordered one for my Terrain and a class 2 hitch. Although the harness for the car was the wrong part,the customer service dept. took care of it immediately and it fit and installed with ease. The hitch went on with no problems and their videos showed everything you need to do. These guys will get my business from now on. a+++
Installation of the T-Connector was extremely easy once I released the lock that held the factory cover in place, however, I don't recall seeing mention of the fact that the dealer has to "flash the ECU" [computer] to enable and turn on the factory wiring harness. I spent quite a bit of time troubleshooting no lights before finding mention of this on the internet and confirmed with a dealership that wanted $160 to do this work.
Trailer hitch fit like a glove and looks great. The wiring harness was exact fit and will have to go to the dealer and have the vehicle part of the wiring turned on. Instruction and video on e-trailer helped a lot to determine my needs and installation.
Installation went well. You will need to cut the spare tire splash cover. Its made of plastic and was easy to cut in place with a, multi tool saw.
Also the Curt T- wiring harness # C55515 plugged in easy as well.
I would also recommend the mounting bracket # 18144 for a nice clean job.
On the 2017 Durango you will have to have the dealer activate the tow plug (flashing the computer ).
No lights after installation. Don't think it was product's fault. Dealer told me vehicle did not have module for trailer lights, even though it had the connection for your harness. Ugh!
After going to many auto stores trying to track down this wiring harness I finally found it at Etrailer. Had the part in my hands before they said it would arrive. Could not beat the price. Thanks again Etrailer.
Shipped on time. Installed very easily with help from the video tutorial. Works great and easy to connect trailer on and off that is after I went to the dealership so to activate the trailer lights from the computer because I did not have the tow package when I initially bought the car.
Product was easy to install into the Chev Silverado's existing wire harness. The provided zip ties allowed me to route the 4-wire unit beside existing wiring to the hitch receiver area. Be sure to review the provided videos on simple installation.
PERFECT ! What a pleasant experience from the friendly folks i talked to and on to package being deliveried as said by ups to my door step , a perfect fit i put in on by myself about 25 minutes wiring harness work just like a factory installed one.
I did have to take my Jeep back to dealer for a computer program feature update by working fine.
Will rate 100% Great job to all
Bought this to use on my '03 Trailblazer. Still works good after 1 year of use towing the boat. It even got road tested once since I hadn't plugged it in all the way and it fell out and drug on the ground for a mile or so. :-)
I have another plug/adapter, but I needed the extra length this piece gives me...
I am happy with 4pin plug is wired correctly....I bought one from someone else,
and it was NOT...etrailer is my go too for trailer products....
Connected to my 04 tahoe (base model) just like it should

Hey Nick, that sounds super frustrating. Do you know if your Jeep equipped with a tow package? I'm happy to help if you still in need of a harness.
