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 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.

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: Lisa05/28/2019
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.

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.

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.

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: Jack L10/02/2019
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: Carter 07/01/2022
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: Jeremey03/24/2022
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.

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!!!

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.

- 4-Way Trailer Wiring Harness Recommendation for a 2007 Dodge DakotaYou 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.
view full answer... - Will a 2007 Dodge Ram and 2005 Ford Trailer Connectors Match to Tow the Same TrailerWiring 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...
view full answer... - Which T-One Trailer Wiring Harness Fits a 2004 Toyota Sienna Van?The T-One is a custom fit wiring harness, but part number 118381 will not fit your 2004 Sienna Van. This harness is custom fit for a full-sized Dodge van. We do offer a custom harness for the Toyota Sienna Van, the T-One wiring harness you need is part number 118304. For your convenience, I will attach links to the referenced products, a helpful FAQ wiring page and an installation video for the 2004 Sienna.
view full answer... - Correct Tow Wiring Harness for 2008 Jeep LibertyIf 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...
view full answer... - How Do I Install a 5-way Flat Connector at the Back of my 2006 Jeep Commander to Tow my BoatIn order to have a 5 pin flat trailer connection you will first need to install the Tow Ready Custom Fit Vehicle Wiring, part # 118381, that you referenced. I attached installation instructions and a link to an installation video for this product below for you to check out also. The next thing you will need is an Adapter 4 Pole to 5 Pole Trailer Wiring Adapter, part # 20036. This adapter will plug into the 4-way that you just installed with the # 118381, and then you can run the blue wire...
view full answer... - Trailer Wiring Harness for a 2005 Dodge DurangoIf 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.

If the Liberty did not come with a tow package, you will need T-One Connector w/Upgraded Circuit Protected ModuLite, # 118524. A powered converter is required to protect the vehicle sensitive electronics on models not equipped with a tow package. If your Liberty did come with a factory tow package, you would need Tow Ready Custom Fit Vehicle Wiring, # 118381. A Liberty with a tow package has a wiring harness made...

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 the Durango does not have a tow package, you will need to use a different wiring harness, # 118334. This harness plugs in line with the vehicle tail light wiring. I have...

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...
view full answer... - 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.
view full answer... - How To Choose the Correct Trailer Wiring Harness for a 2002 Dodge DurangoThere are two different trailer wiring harnesses for a 2002 Dodge Durango which will be dependent on whether or not you have the tow package. If you do have the factory tow package then you can use the T-One Vehicle Wiring Harness part # 118381 which only uses one plug but if you don't have the factory tow package then you will need to use the T-One Vehicle Wiring Harness part # 118334 which uses two plugs. It doesn't sound like you have the factory tow package therefore will need the...
view full answer... - How to Determine with 2006 Dodge Durango has Factory Tow PackageIf you already have a 7-Way connector at the rear of your 2006 Dodge Durango then the T-One # 118381 is the correct part. 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. An installation video and the written instructions for both kits have been linked for you to...
view full answer... - Trailer Wiring Recommendation for 2007 Mercedes Sprinter RV ChassisFor 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.

This is the only option that has a concealed cross tube which gives it a cleaner look and better clearance. However, since it sounds like you do not have factory trailer wiring you will want the T-One Vehicle Wiring Harness with 4-Pole Flat Trailer Connector # 118334 instead of the # 118381. The wiring harness you ordered is designed to fit vehicles that already have a factory 7-way. You...

From there you would need to convert the 4-way to a 7-way so that you can install the brake controller. For that you will want the Brake Controller Install Kit and 7-Way Adapter part # ETBC7.

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.

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.
