Quickly and easily install a 4-way trailer connector on your vehicle using this custom wiring harness. T-One connector plugs directly into existing factory 7-way - no cutting, splicing or tapping required.

Installation
This custom-fit T-One connector plugs into your vehicle's wiring harness, which is located behind the rear bumper, on the driver's side.
Once installation is complete, the 4-way flat connector will be stowed beneath your vehicle, near the trailer hitch. A mounting bracket (sold separately) is recommended to keep the connector secure.
It is recommended that you use a small amount of grease on all electrical connections - the plugs on your automobile and the 4-pole connector itself - to help prevent corrosion.

Ugh, it looks like the shipping has been updated via the tracking number and you should be receiving the order today at some point [9-18]. Please let me know if you do not receive it this evening. I would also love to hear your feedback on your experience once you actually do receive the item. I am sorry for the inconvenience this has caused you.
did not fit I had to splice in 14" of wire so it could reach the two tail lights
and this was the second one I purchased the first one did not have the correct connectors

This part is meant for Jeeps that have the factory tow package. I am wondering if that is the issue here. If your jeep doesnt have that then you would need part # 118425.
I recently recieved my tow hitch for a 2000 Dodge Dakota. The part arrived promptly and in excelent condition. I was very pleased with the quality of this hitch by Curt. It was very stout and had great welds. I haven't had a chance to mount the unit yet but the measurements look to be right on. etrailer.com has a new customer.

The kit was extremely easy to install and fits like a fine glove. So easy in fact that the factory could not have done better looking job. Works great although I rarely use my trailer but I know when I do, I can rest assured that the wiring will not be a problem as it used to be.

have since started driving a different vehicle. My jeep bit the dust. I liked the harness and it always worked fine but I didnt get to use it too long. I do remember how easy and well thought out the installation process was. I do keep a link to your website and have turned on others to it. Sometimes it was already too late but now they know its there. Ill definitely keep you guys in mind in the future
The product was everything that was advertised it arrived in perfect condition I guess I just misunderstood what I needed and inevitably ordered the wrong part my 05 Jeep Liberty did not come with a 7-way so I need a different harness to be able to hook up my trailer should have called customer service first

If your Liberty didnt have the factory 7-way, I would recommend the # 118524 Tekonsha powered taillight converter.
Fit just like advertised. They have excellent customer service. Videos and pictures were a great help.
This product was what was recommended by your site as the proper wiring harness and it IS NOT compatible with my vehicle. Our family’s vacation has already been pushed back by 2 days dealing with this situation and we are still working on finding a local solution!

This wiring harness is only compatible if your Freightliner Sprinter has the factory equipped 7-way trailer connector, as we state in our product fit guide. If your Sprinter does NOT have the factory 7-way, youd need part # 118650 instead.

etrailer received, filled, packaged and shipped my small order (wiring harness) within an hour, then turned it over to the US Post Office.... Within 2 days, it crossed the state line from Missouri into Illinois. A few days later, it was received in Chicago and should have arrived in Canada in short order.... Instead, tracking my order a week later revealed that it was resting comfortably in Miami Florida. A call to etrailer and Carol soon straightened things out. It eventually found its way to me and I am quite pleased with the service from etrailer. The Post Office? Well, you know..... Bobber.
The T-wire harness was great, installed well and works fine.
The Seat covers are great as well, durable and easy to install, will consider rear seat covers if available?
The stabilizer bracket would not work with my platform rig, but looked of good quality and I will find a use for it.
Bought this for a 2006 Dodge Sprinter didn't realize it would not work on a Sprinter with out towing package. Had to buy different kit and splice the wires in (not fun) make sure you have the right kit if you are working on a Sprinter. On a vehicle with the right harness it works great just plug in and go.
perfect fit fast install!!
Thanks to etrailer's excellent customer service, I was FINALLY able to order the correct wiring harness for my '01 Dodge Durango. There are many variables due to several Durango models, and this was the correct one. Has worked flawlessly since installation.
It would have been very easy to install but my truck did not have the quick disconnect behind the bumper.

You mentioned that you were not able to find the connector and I wanted to ask if you were adding on the 4 flat or replacing it.
Easy to install, hidden when not in use, doesn't reduce ground clearance and trouble free. Local hitch installer quoted me $350 and said it would take 3" off my clearance. I saved over $200 and got a better setup.
Super easy to install and worked right away, no additional fuses or lights necessary. Videos were easy to find on [online] and very easy to follow. Would recommend this to anybody. Mine did not come with the double sided tape, but I had some lying around so no worries.
I've had this on my truck for a year to pull my little 5x8 utility trailer for work. It's worked every time so far and haven't had any issues with it. So far so good. Oh, and it only took about 20 minutes to install of you're into that kind of thing.
I was in a hurry and I bought the wrong wiring harness. I have ordered the right wiring harness and it is on the way. My truck does not have the factory trailer connections for the wiring harness that I ordered.
didn't even install it .... my Dakota had no hook up ... had to hardwire a connector .... waste of $15 , not even worth my time returning it .... I did buy a hitch that I am using though ... should have bought a chevy
Wrong product .. reordered correct one .. said this was 4 pin connection, but requires vehicle to be equipped with 7 pin connection from factory. Guess you have to read the fine print

For a 2004 Dodge Dakota with a factory seven way this harness adds a 4 flat. For a 2004 Dodge Dakota that did not come with a factory harness part # 118323 would be a fit.
Perfect fit! Just plugged it in with a little dielectric grease in the connector and it has performed flawlessly.
I’ve had this over a year now and it has held up to so relatively extreme overland camping trips in that time. I would purchase another if I ever had to, but with the quality provided… I probably won’t ever have to replace it. It may be hard to install on some vehicles, it was hard in mine, but very worth it and to no fault of the product, just the design on my Jeep.

A year out still 5 stars. Its common on these 4 pin connectors to have the plastic rub off next to the single exposed pin, this is no different. Still functional and stays connected throughout use.
