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.

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.

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 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.

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 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.

Barry B.

10/25/2018

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



by:

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

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:

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:
2002 Jeep Grand Cherokee

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



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:
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:

perfect fit fast install!!



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:

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.



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:

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!!!



by:
2007 JeepLiberty

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:
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:

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



by:
2000 Jeep Grand Cherokee

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....

  • Will a 2007 Dodge Ram and 2005 Ford Trailer Connectors Match to Tow the Same Trailer
    Wiring the trailer to match the pin out on the 2007 Dodge Ram should allow it to work with the 2005 Ford as well. The reason is that vehicles generally have the same pin out on the trailer connector, the two most common being a 4-Way flat and 7-Way blade style. To make sure everything matches up and just to be on the safe side you can use a circuit tester like # 3808 to test the functions on the vehicle side connectors. On the trailer side you can either trace each wire back to determine...

  • 4-Way Trailer Wiring Harness Recommendation for a 2007 Dodge Dakota
    You will only need to order a quantity of 1 of the T-One Vehicle Wiring Harness # 118381 to install a 4-way on your 2007 Dodge Dakota. Check out the install video I attached to see how it installs.

  • 4-Way Trailer Wiring Recommendation for a 2001 Dodge Dakota
    If you have a round 7-way at the rear of your 2001 Dodge Dakota you would want the part # 118381 for trailer wiring. If you do not have any trailer wiring present at the rear of your vehicle you would want the part # 118329. I attached install videos for both products.

  • Correct Tow Wiring Harness for 2008 Jeep Liberty
    If your Liberty was equipped with the tow package, it will have the 7-way trailer connector on the rear of the vehicle. Part # 118381 would plug inline with the wiring harness leading to the 7-way. Since you do not have the factory hitch, you probably do not have the tow package and would want to use part # 118554. Installation is pretty simple. Access the rear of the tail light assemblies, plug the connectors inline with the existing connections behind the tail lights, and run the power...

  • How Do I Install a 5-way Flat Connector at the Back of my 2006 Jeep Commander to Tow my Boat

I attached installation instructions and a link to an installation video for this product below for you to check out also.

  • Trailer Wiring Harness for a 2005 Dodge Durango
    If your 2005 Dodge Durango came with the factory installed 7-Way and for whatever reason it is no longer there then yes, using # 118381 will provide the lighting functions for the trailer: running lights, brake lights, and turn signals. If the vehicle did not come with a factory trailer connector then you would use harness # 118390 which plugs in line with the vehicle tail light wiring and requires a direct connection to the vehicle battery. I have linked some videos and instructions for you.

    For your 2007 Jeep Liberty, there are a couple of trailer wiring options.

  • Wiring 2007 Dodge Ram 3500 For Installation of Flat Bed
    We don't offer a direct part, but I know how you could fabricate a pigtail. You'd need part # 118381 that would plug inline with the harness that plugs into the rear of the 7-way. You could simply cut the 4-pole off and wire the yellow wire to the left turn, the green wire to the right turn, ground the white wire and run the brown wire to the running light and jumper it over to the running light on the other side. This set up would provide you with a quick disconnect. You'd need to wire...

  • Will a T-One Vehicle Wiring Harness fit Into a 2005 Jeep Grand Cherokee?
    The T-One Vehicle Wiring Harness, # 118394, will fit a 2005 Jeep Grand Cherokee if it does not have the factory tow package, and because your hitch is not factory, is is likely you do not have that package. If it turns out you do have the factory tow package, you would need the Vehicle Wiring Harness with 4-Pole Flat Trailer Connector, # 118381 I have added links to video reviews and an install video for you to take a look at.

If it does have a factory tow package, check the owners manual to find the fuses and/or relays related to the tow package to determine if anything is missing or needs to be replaced.

If you don't have a 7-Way then you would need the T-One # 118390 which is for an '06 Durango that doesn't have the tow package. This kit tees in right behind your tail light housing and pulls power directly from your battery to help protect the OEM wiring on your Durango.

  • Trailer Wiring Recommendation for 2007 Mercedes Sprinter RV Chassis
    For your 2007 Dodge Sprinter RV chassis the brake and turn signals are sent along separate wires. A converter is required unless the vehicle is equipped with a tow package plug. The tow package plug has already been converted. If you need a 4-way and you HAVE the tow package you only need the part # 118381, if you do not then you'd need the part # 118650 which does use a converter box.

If you do have the tow package that means you have a 7-way connector on your Jeep; if the U-Haul had a 4-way connector you could add a 4-way to your Jeep with the T-One Wiring Harness # 118381 which simply connects to your Jeep's existing 7-way by plugging in.

The hitch can either be bolted or welded on and will work with box frame, C-channel frame, or I-beam frames.

If so, then you'd have the tow package and the kit you'd want is the # 118381 which would plug inline with the 7-way you have to give you a 4-way.
