Installation
This custom-fit T-One connector plugs into your vehicle's wiring harness, which is located behind the driver's-side and passenger's-side tail lights. You will have to remove the lower interior trim panels and the tail light assemblies to access this 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 the side storage compartment.
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 Powered Tail Light Converter
A ModuLite power module is built into this T-One connector. Because your vehicle runs on a multiplex wiring system, the wiring needs to be converted to be compatible with the wiring system of your trailer. This power module functions as a tail light converter to combine the brake and turn signal functions of your automobile so that they run on one wire to properly activate your trailer's tail lights. Note: This will not affect how the tail lights on your vehicle operate.
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.

Quickly and easily install a 4-way trailer connector on your vehicle with this custom wiring harness. T-One connector plugs directly into existing wiring. Powered ModuLite reduces strain on wiring system.by: Chris07/22/2022
I received the shipment timely and the updates while in transit were excellent. However, the shipment had minimal packaging and was in bad shape when it arrived. Fortunately, there does not seem to be significant damage to the hitch and I located all of the parts for the wiring kit.

As far as vehicle installations go, this went about as smooth as possible. Even if you are only slightly mechanically inclined, you should be able to tackle this install. All of the connectors fit right up on my vehicle as expected. Nothing unexpected. The How-To video was VERY helpful and guided me the entire way. 10/10!
by: Ben01/24/2023
I like the connections and distribution box as well as the instructions/video. Two points I would add are that there is a ground bolt when you open up the left side panel to get at the tail light. Probably better to use that than a self tapping screw that might lose its continuity.
Next, it’s difficult to run the wire through the suspension/frame in the left rear. I zip tied it to the top of that, keeping it away from any moving parts. Lots of zip ties and making sure to trim off any loose ends. Running it through the sill is no problem but when you get to the end instead of going up into the engine bay where it’s difficult to zip tie and is close to the exhaust system, you might want to run on the inside of the felt in the wheel well. You’re already taking off two of the T 25 screws when you go forward through the sill and reach the end, so all you need to do is remove three more T 25 screws at the edge of the wheel arch and two 10 mm plastic nuts. Then you can pull the felt away from the wheel arch and run the wire up and underneath a foam block that is at the top. Up in the engine compartment, that comes out just forward of the positive lug, underneath the metal that the lug is bolted to. It might help to place the wire up underneath the foam as far as you can and then reach back from up in the engine bay to fish it forward. I think either way you do it you can get a clean install and a working connector. Just food for thought.

Easy to install and continues to work after extensive use.

The wiring was exactly as advertised and fit perfectly.

2014 VolkswagenTouareg
I installed this wiring harness at the same time I installed a hitch on my VW Touareg. The video provided online was a huge help and complimented the very detailed, application specific instructions provided. There was only 1 part that I thought could be more specific and that was when it came to getting the long black wire that gets routed to the engine compartment, out of the rear of the vehicle. I ended up popping out a round rubber gasket from the wheel well and routing the wire out there. The video indicates that you can feel around and find a "vent" for the wire to exit through. Either way, I was able to get everything connected, and even though it took a bit of time, it was relatively simple. I'm only "handy" not a mechanic or electrician, but after watching the video I realized that this would be pretty simple and wasn't anything that I couldn't handle.

I purchased a trailer wiring kit for a 2013 VW Touareg. It was the easiest trailer wiring Kit that I have ever installed. etrailer.com has complete & easy to follow on line instructions. The best part is that the kit, 118668 has tail lite plug adaptors for a quick and EASY connection.

Works well, fairly simple install. Be careful to not drop the right hand tail light retaining screw, definitely adds time to the install!

See what our Experts say about this Tekonsha Custom Fit Vehicle Wiring
- Troubleshooting Driver and Passenger Turn Signal On Tekonsha T-One 118668 Not WorkingI would start with checking the white ground wire that got grounded to your 2014 Volkswagen Touareg, as this is a pretty common issue when a ground does not have a good connection. Make sure the ground is secured to clean corrosion free metal. Next remove both of the tail lights on your vehicle, and check that the pins inside of the connectors of the # 118668 are not bent or damaged. If all of those check out, use your circuit tester to check the yellow and green wires coming into the...
view full answer... - Amperage Draw of Tekonsha Trailer Wiring Kit For 2012 Volkswagen TouaregThe amperage rating for the Tekonsha trailer wiring harness part # 118668 that you referenced is 4.2 amps per each stop/turn circuit and 7.5 amps for the running light circuit. While I certainly understand how tempting it is to power the wiring kit from a more convenient circuit to access than the vehicle battery you really have to make sure you use the vehicle battery only as it's only method that won't void warranty. The reason it draws from the battery is so that it can totally bypass...
view full answer... - Does Computer have to be Flashed to Install Trailer Wiring Harness on 2013 VW TouaregT-One Vehicle Wiring Harness with 4-Pole Flat Trailer Connector Item # 118668 plugs in line with the tail light wiring on your 2013 Volkswagen Touareg and not to any factory tow package wiring so the vehicle computer would not have to be flashed. However, if VW has a special software update that enables the vehicle for optimum performance when towing then it is a good idea to do it especially if it alters the transmission shift points to work best when towing!

This harness will plug into your vehicle's wiring harness, which is located behind the driver's-side and passenger's-side tail lights. I attached a picture of instructions on how to un-install the wiring. I attached an installation video link below.

- Left Turn Signal And Brake Lights Not Working On 2013 Volkswagen TouaregIt sounds like it could be a weak ground. Check to make sure your grounding point on the vehicle is on a nice piece of metal that is clean and free of rust or paint. It is also a good idea to check the connectors coming off the vehicle with a circuit tester # PTW2993 to verify they are in proper functioning order and is receiving the correct voltage. I have attached a help article to aide you in your troubleshooting.

I do recommend using a Circuit Tester # PTW2991 for testing your connections. This will help ensure your ground connectors are working properly as well. I do not see a black wire with green tracer coming out of the black box. The black wire is the 12V constant power. Your output wires are green for right turn/brake, yellow for left turn/brake, brown for running lights and white is ground. I hope this will help you identify...
view full answer... - Trailer Wiring Harness for 2013 Porsche CayenneThe # 119179KIT harness you mentioned isn't vehicle specific, but it could be installed by tapping into the taillight wiring harness of your Cayenne. When the vehicle in question is a European vehicle like the Cayenne, I'll typically recommend going with the # 119250KIT. Instead of physically tapping into the vehicle wiring, the # 119250KIT uses sensors that snap around the individual brake lamp, turn signal and running lamp circuits without piercing the wire. Even though the wire insulation...
view full answer... - Trailer Hitch Recommendation for 2011 Volkswagen Touareg for Towing Travel TrailerWe have trailer hitches that fit your 2011 Volkswagen Touareg that have more than enough towing capacity for towing the travel trailer you mentioned like the Draw Tite # 75950 but none of the hitches we offer for your vehicle can be used with a weight distribution system as they were not rated for this application. So you'd still be able to tow your trailer but not be able to use the WD system. For trailer wiring you'd want the part # 118668 which is a custom fit kit for your vehicle and...
view full answer... - Trailer Wiring Harness to Fit 2011 Porsche CayenneWe do not have a wiring harness that plugs directly into the wiring of a 2011 Porsche Cayenne. The # 118668 that you referenced is for the Volkswagen Touareg but hasn't been confirmed to fit the Cayenne despite their similarities. The harness that will work with your Cayenne is # 119190KIT. This will be hardwired into the Porsche. I've linked videos the wiring harness being installed on the similar Audi Q7
view full answer... - Trailer Wiring Harness for a 2011 Porsche CayenneThe 2011 Porsche Cayenne is one of those vehicles that is hard for manufacturers to get in order to perform test fits of things like wiring harnesses or other custom fit parts. This is the case with many high-end vehicles like yours and likely the reason that there are no T-connector type wiring harnesses available. To avoid having to cut and splice a wiring harness into the vehicle's tail light wiring I recommend ZCI Circuit Protected Vehicle Wiring Harness w/ 4-Pole Flat Trailer Connector...
view full answer... - Recommended Trailer Wiring Harness for 2015 VW TouaregThe Hopkins 7- and 4-Pole Trailer Connector Socket w/ Mounting Bracket # HM40975 referenced in your question is intended as a factory replacement. If your VW Touareg came with a factory 7-Way connector and you need to replace it, this item will work perfectly. Otherwise, if your vehicle does not have an existing factory connector at the rear bumper, I instead recommend the T-One Vehicle Wiring Harness # 118668. This custom-fit harness will install by connecting directly to the built-in...

Since you mentioned your turn signals are not working, I recommend you double check the installation and ensure you have a good 12V power connection to your battery and clean metal to metal ground to your vehicle frame or metal body support. I recommend using the circuit tester # PTW2993 to check each function. I've attached a video and an...
view full answer... - Trailer Wiring for 2012 Volkswagen Touareg for Installing Brake ControllerThe correct 4-way trailer wiring harness you'd need for your 2012 Volkswagen Touareg is actually the part # 118668. 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. I attached installation instructions and an install video for this product as well. Then for a brake controller you could use the # 39510 and you'd be set.
view full answer... - Trailer Hitch and Wiring Recommendation for a 2015 Volkswagen TouaregFor your 2015 Volkswagen Touareg we offer a hitch and wiring solution that would be MUCH less expensive than what the dealer wants to charge you. For a hitch the Curt part # C13116 is a popular option that would work very well for you. I attached an install video for you to check out as well. If you wanted to do some towing you might be interested in etrailer ball mount kit # 989900. It comes with 2 ball mounts; one with a 3/4 inch rise or 2 inch drop and one with a 2-3/4 inch rise or...

To install a brake controller like the Tekonsha P3 # 90195 you will need a 4-way wiring harness installed and then to gain the proper brake controller functions you will need to adapt the 4-way to a 7-way. The 4-way I recommend for your Touareg is # 118668. We do have an installation video of this being installed on your same vehicle. To adapt this to a 7-way, I recommend the # ETBC7, this kit...

- Does Power Wire Need to Be Run to Battery for T-One Wiring Harness on 2013 Volkswagen TouaregThe T-One Vehicle Wiring Harness with 4-Pole Flat Trailer Connector part # 118668 which is a fit for a 2013 Volkswagen Touareg requires a power wire to be run from the converter at the rear to the battery in the engine bay per the instructions. This is the only way to ensure the circuit is rated appropriately for the power demands of the trailer lights. We get asked this often about pulling power from somewhere at the rear of the vehicle but unfortunately, we simply cannot recommend this...
view full answer... - Brake Controller Installation 2014 Volkswagen TouaregIf your tow package includes the factory 7-way trailer connector on the rear bumper, you'll need a few parts from the dealer. You'll need one #1J0-972-782 housing and (qty. 2) #000-979-228-E wire/terminal assemblies. I've linked to the tech bulletin that explains the procedure as well as to an install video showing how those VW parts work. I've also linked to a demonstration video explaining how the Spectrum Brake Controller works.

But, you can still install a brake controller. There are several components you will need. First, if the vehicle does not already have a 7 or 4-Way trailer connector, you will need to add one. To add a 4-Way you will need # 118668. I have included a link to the installation details and a link to a video showing a typical installation of this harness for you. To then add...
