  • Connects quickly and easily to your existing 7-way - no cutting or splicing of wires

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.

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.

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.

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.

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.

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!

Etrailer Expert

5/29/2019

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.



by:
2002 Jeep Grand Cherokee

Fit just like advertised. They have excellent customer service. Videos and pictures were a great help.



by:

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.



by:

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.



by:
2006 Mercedes-Benz Sprinter

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.



by:
Dodge Durango

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.



by:

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.



by:

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.



by:
2000 Dodge Dakota

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.



by:

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.



by:
2007 Dodge Dakota

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



by:
2007 Jeep Liberty

I watched a video of theirs on Youtube which linked to the correct part and I bought what the video linked to, assuming it was the one shown in the video (without the factory 7-way). They sold me the one that uses the factory 7-way (which I don't have) and when I called asking to exchange it for the right one, they said it wasn't possible. They said they'd take it on refund, but are charging me for return shipping, and considering it's such a lightweight and cheap part to ship (and their website's mistake), I'm losing a significant portion of the money I spent on it.



by:

Perfect fit! Just plugged it in with a little dielectric grease in the connector and it has performed flawlessly.



by:

website was very helpful and easy to use. Told me exactly what to order and how to install, Items arrived and installed exactly like they said they would. Saved us $300 dollars and have exactly the same hitch we were quoted at several different trailer install places. Thank you etrailer!!!

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.

Well made onlu problem is they don't give you enough wire to reach the trailer from the factory 2000 jeep grand Cherokee harness... looks like iI'll be splicing some extra length anyway....

  • 4-Pin Wiring Harness for a 2010 Jeep Grand Cherokee w/ out the Tow Package.
    Yes, we do sell a 4-pin wiring harness for a 2010 Jeep Grand Cherokee without the factory trailer package. It is the Tekonsha T-One Vehicle Wiring Harness with 4-Pole Flat Trailer Connector item # 118425. This custom-fit T-One connector plugs into your Jeep's wiring harness, which is located behind the tail lights. Some other parts you may need for towing are a trailer hitch item # e93AR is confirmed to fit your Jeep. I also recommend the Curt Towing Starter Kit for 2" Hitches item # C45534.

  • Will the Draw-Tite Hitch # 75210 fit a 2006 Dodge Sprinter with a Factory Step Bumper
    The Draw-Tite Class III 2 Inch Hitch, part # 75210, is for a 2006 Dodge Sprinter with a 140 inch or 158 inch wheelbase and either single or dual rear wheels. It will not fit the 118 inch wheelbase vehicle. To fit the Sprinter with the dual rear wheels the width between the frame rails will need to measure 35-1/4 inches.

  • Recommendation for a Class V Trailer Hitch that Will Fit a 2007 Dodge Ram with Factory Trailer Hitch
    We do have several trailer hitches that are designed to fit beneath the factory trailer hitch on a 2007 Dodge Ram. You can use Curt Trailer Hitch # C15704 if you want a 2-1/2 inch trailer hitch receiver. Hitch # C15409 has a 2 inch receiver. The recommended ball mount for a 2-1/2 inch hitch is # RP45323, and you can use pin and clip # 37201065. For a ball you can use # A-90 (2 inch diameter) or # 19286 (2-5/16 inch diameter).
