Installation
This custom-fit T-One connector plugs into your vehicle's wiring harness, which is located inside your trunk, behind the tail lights on both the driver's side and passenger's side. You will need to remove some interior trim or carpeting to access the harness. Once you've plugged in the T-connector, run the hot lead up to your car battery. Connect the lead to the included fuse holder, and then connect the fuse holder to the positive terminal on your battery and insert the provided fuse.
Once installation is complete, the 4-way flat connector will be stowed within your trunk.
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.
ModuLite Power Module
A ModuLite power module is built into this T-One connector. With a ModuLite, your trailer's lights will be powered without overloading your vehicle's electrical system. Because the module draws power directly from your car's battery and bypasses the electrical routes that are used by a basic wiring harness, there is virtually no draw on your tail light circuits.

Installed both hitch and wiring this morning. Pretty straight forward - watch the videos to get a good idea, pre-install.
Only regret is I should have ordered the Jetta specific ball hitch at the same time as the hitch and wiring. Thought I could find it locally, but now will pay for shipping...
by: Brian06/05/2023
Arrived on schedule in good condition despite horrible packaging (parts of the Hitch were protruding from the box.
Installation was fairly straightforward. Images in instructions could have been bigger.

It could use a better instruction sheet with sharper pictures & clear steps, e.g. where is step number 9? A routing guide for the power lead would help. Quality of manufacture seems good and works as expected.

Yikes, you are right! It does seem step 9 went missing. I think what has happened is that when the manual was last revised the steps were condensed however the numbering became off. I did contact the manufacturer about it. In the meantime we do have a FAQ that can help when it comes to routing the power wire.

Fantastic product. I wanted to add a trailer harness without cutting or splicing any of the car wiring. Installation was a breeze, and the system works like a charm. The one change I made was to add a plug for one of the lighter sockets rather than run a wire all the way up to the battery. My car has a pass-through from the trunk, so it's easy to plug in the power cord when I want to hook up the trailer.

Fairly easy install after watching the YouTube video posted on website. The instructions were not the easiest to follow when it came to feeding a bolt and bracket through the frame due to lack of pictures to show which hole to use but otherwise looks clean. Highly recommend to watch install video. I love the wiring harness and the fact no splicing of factory wiring was required. I have not cut my original plastic cover on bottom of car to reinstall around the tow hitch yet but do intend to put back on the car.
by: Lonnie05/31/2016
Product arrived 2 days later along with my trailer hitch; free shipping. Both videos were a godsend. It's so much easier to watch a video compared to a diagram. I wish more companies would follow suit. The pre-made harness with the plug-and-play comcept was a definate upgrade compared to the old style where you had to clip to existing wires. This way, it could always be removed with damaging the existing harness.

This kit made my Curt hitch install complete. With plug and play wiring adapters, 12 gauge power wire spool supplied, I had this wiring harness installed in no time. I recommend taking your time and removing all cargo panels and trim to install this harness. It makes for a seamless professional install. Thank you!
by: Robby 01/23/2021
I had purchased a wiring harness that was not custom made for my vehicle, but it was not up to the task, (or I was not sharp enough to get it done). The harness from E Trailer fit nicely and the customer support was excellent!
by: Dwyer R.05/22/2017
2009 Volkswagen Jetta
This part works well. The installation to the tail lights themselves was very simple and only took about 10 minutes. Running the power supply from the battery to the trailer took some time (~2 hours) though. The difficult part was accessing the engine compartment through the firewall on the driver's side. Would be helpful to have more vehicle-specific pictures on this step. Otherwise, the installation process was seamless with a simple electrical wiring kit.

I used the hitch and harness for about 6 months and it worked awesome! Could not be happier. I sold the car and really wish the hitch transferred to my New car because it was so useful
by: Sam07/12/2019
When it showed up wasn't expecting the hitch to be so beefy! Excellent build quality and paint, this hitch is SOLID. The wiring kit I also ordered was very high quality and well built. I would definitely recommend any of etrailers products to anyone looking for hitches and accessories.

2006 Volkswagen Jetta
The so called T-connectors fit the factory taillight plugs perfectly. The only irritating part of this install was running the wire from the unit to the battery at the front of the car.
It would be nice if the unit came with a 12V cigarette lighter adapter, as my car has a plug in the trunk. If that was included install would have taken about 5 minutes tops. I may actually make one now that I think of it.

The wiring kit works great. It was easy to install and came with everything needed. The video describes exactly how to install it. I have had It installed on my jetta for more than a year and it has been great.

I purchased this item for my 2009 Jetta TDI. I didn't feel like cutting my factory wires so I went with T-One Connector, plug and play great item and has everything what you need to do the job.
by: Wendell S05/03/2020
Great product and worked well. Easy installation with great instructions and good price. Would highly recommend. So far no issues.
by: Brandon05/21/2020
Plug and play, very easy installation. The instructions say to run a wire directly to the positive terminal on the battery. I just spliced in the 12V socket in the trunk instead.

Great idea to make a plug-in trailer harness. Easy to install and works .

great product received it today and installed this afternoon. Very easy install except for routing the power wire to the battery. Took approximately 15 min. to install the system and 2 hrs. to route the power wire.

This is my third time using this product. This unit was purchased to replace an existing unit that failed after 2.5 years and being subject to 2 or 3 hard shorts. The product is easy to install and etrailer usually ships it faster than quoted.

- Recommended Trailer Hitch/Trailer Wiring For A 2009 Volkswagen Jetta TDII recommend the Draw-Tite Sportframe Trailer Hitch Receiver # 24866 for your 2009 Volkswagen Jetta. The Curt hitch is not confirmed to fit the TDI model of your Jetta. The Draw-Tite hitch has a bolt-on installation with no welding required and has a black powder coated finish that offers a superior rust protection. For the wiring harness you will need the T-One Vehicle Wiring Harness # 118667. I like the T-One harness over the other harnesses that we offer because it has a more reliable...
view full answer... - Ground Clearance on Available Trailer Hitches for a 2006 Volkswagen JettaOn all of the available trailer hitches for the 2006 Volkswagen Jetta, the receiver and cross tubing will be fairly low. This is because of the attachment point placement on the VW frame. By design, the hitches have to be that low. On all the models, the top of the receiver tube will be just below the rear fascia. We have several videos you can view (linked below) on the Draw-Tite, Valley, and Hidden Hitch models that show the hitches installed to give you a better idea of the kind of...
view full answer... - Draw-Tite Sportframe Trailer Hitch Receiver for 2009 Volkswagen Jetta TDI SedanI have a solution for you but EcoHitch does not make a hitch receiver for any 2009 Volkswagen Jetta model. I checked with Ecohitch they did not start making hitch receivers for the Jetta SportWagen model's until 2010 and the Jetta sedans until 2015. I recommend the Curt Trailer Hitch item # C11474. This hitch receiver is a confirmed fit for the TDI models. It has a towing capacity of 2,000 lbs and maximum tongue weight of 200 lbs. This is a class 1 hitch with a 1-1/4" x 1-1/4" receiver...

- No-Splice Trailer Wiring Harness for 2014 Volkswagen Jetta SportWagenI do have a solution for you, but there isn't a custom plug-in T-Connector available for your 2014 Volkswagen Jetta SportWagen. The Tekonsha # 118667, you were looking at, only fits the Sedan models of the Jetta. For a no-splice solution, you can use the ZCI Circuit Protected Vehicle Wiring Harness # 119250KIT. This universal kit uses sensors that simply clamp to your factory tail light wires so no cutting or splicing is required to install it. The ZCI sensors are able to read the signals...
view full answer... - Trailer Hitch and Wiring Recomendation for 2006 Volkswagen Jetta SedanFor a trailer hitch confirmed as a fit for your 2006 Volkswagen Jetta sedan you'd want the Curt # C11474 which is a confirmed fit and would work well. For wiring you'd then want the Tekonsha kit part # 118667 which is a confirmed fit and would work well. For a ball mount you'd want the # 3593 and then for a 2 inch hitch ball part # 19258.
view full answer... - Trailer Hitch Receiver Fit for 2007 Volkswagen Jetta WolfsburgWe do have a trailer hitch receiver that fits your 2007 Volkswagen Jetta Wolfsburg, so long as it is the 4-door sedan and it does not have the diesel engine. If your '07 Jetta Wolfsburg meets those specs the correct trailer hitch fit is the Curt Trailer Hitch Receiver # C11474. I confirmed this fit for you with the manufacturer, and if you plan on doing some towing with your Jetta, there are a few other parts you'll need: - T-One Vehicle Wiring Harness # 118667 - Curt Drawbar # C45520 -...
view full answer... - Trailer Hitch, Wiring, and Accessories to Tow a Rental Trailer with a 2009 Volkswagen Jetta SedanYes. the Curt trailer hitch # C11474 can be used to tow a rented U-Haul trailer. To tow a rental trailer, they will require the hitch and a wiring harness installed on your 2009 Volkswagen Jetta Sedan. You will also need a ball mount, # 3594, and a ball. The size of the ball will depend on what the coupler on the trailer requires. For a 1-7/8 inch ball use # 19256 and for a 2 inch ball use # 19258. For a trailer wiring harness use # 118667 to add a 4-Way flat connector to the rear of the...
view full answer... - Trailer Wiring Harness for 2009 VW Jetta Sportwagen TDIYes, you are correct that Tow Ready wiring harness # 118667 is intended for only the 4-door sedan versions of the Jetta. For a 2009 VW Jetta Sportwagen TDI Tow Ready does not offer a wiring harness. However, Curt does have 4-pole wiring kit # C59236 that is a confirmed fit for the 2009 Volkswagen Jetta Sportwagen Wagon, including the TDI. I linked an installation video for this item showing a 2009 Sportwagen TDI. You can use install kit # 55151 to simplify the process. This includes...

This is a custom fit harness that will allow you to simply plug and play with your current vehicle wiring. There is no splicing or cutting involved with your vehicle wiring. You just run a power wire to your battery, connect the white wire to a clean ground location, and plug the harness in behind your tail lights. I've attached a review video...
view full answer... - Trailer Wiring Harness that Fits 2006 Volkswagen JettaSorry for the confusion but the part # 118667 is the correct trailer wiring harness for your 2006 Volkswagen Jetta. This part number replaced the 118531 that you found reference to which is why it was mentioned.
view full answer... - Process for Adding Electric Trailer Brakes to Leonard Cargo TrailerThe trailer hitches that fit your Jetta are all class I hitches with a gross towing weight capacity of 2,000 lbs and a tongue weight capacity of 200 lbs, which are common ratings for Class I trailer hitches. To verify that you can tow your cargo trailer, you will need to check your vehicle's owner's manual to verify the towing capacity of your vehicle. If the towing capacities of your 2007 Volkswagen Jetta are lower than the towing capacities of of this hitch, then you will be limited...
view full answer... - Trailer Wiring Kit that Fits 2010 Volkswagen Jetta SportwagenThe Tekonsha kit part # 118667 only fits the sedan models of the 2010 Jetta. For the Sportwagen you'd need the # C59236 which happens to be a universal style kit.
view full answer... - Towing a Trailer Level that is 19 Inches from Ground to Coupler with 2010 VW Jetta SportsWagenWhen it is all said and done with the hitch installed and using the appropriate ball mount, the top of the ball will be between 15 and 20 inches from the ground. I know this is a wide range but because every vehicle is slightly different and the tongue weight of every trailer is different this is the best guesstimate I can come up with. I arrived at this figure by taking the ground to receiver tube measurement we took when we installed hitch # C11474 on a 2011 Jetta SportWagen. Then I...

This hitch has a 200 pound tongue weight capacity and 2,000 pound gross trailer weight capacity. Be sure to check the vehicle owners manual to determine the towing capacity of the vehicle.

view full answer... - Trailer Wiring and Method to Charge Trailer Battery on a 2005 1/2 Volkswagen JettaFor the 2005 and 1/2 model year VW Jetta, you will need a T-One Vehicle wiring harness, #118667, if you have the new body style. If you have the older body style, you will need the Hardwire Kit, # C59496. Since the wiring on the harness and your Jetta is not rated for a charging application, you will need to hardwire a connector specifically for this function. You could use part # PK11851, mount it on your vehicle. Connect 6 gauge to 00 gauge wire from the positive battery terminal...

You'll also need to check the tongue weight capacity of the Jetta which could be lower. You're limited by the lowest rated component of the setup.

Then you can use hitch ball # 19256 for a 1-7/8 inch diameter ball or # 19258 for a 2 inch ball. For a 2010 Jetta Sportwagen, the frame is the same so the hitch will be the same but...

We have trailer wiring harnesses that will work with your Rabbit, but none of them are the plug-in style wiring harnesses. I recommend the ZCI wiring harness, # 119250KIT.
