Installation
This custom-fit T-One connector plugs into your vehicle's wiring harness, which is located in the rear cargo area. You will have to remove the plastic threshold cover, side panels, and cargo trays 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 in your rear cargo area.
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 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.

The hitch is great, the wiring is the issue. The fuse blows every trip so I’ve gone through over 15 fuses. Hitch was easy to install but it does scrape when going up even the smallest of inclines.
Great product and worked perfectly. Installation on my vehicle was a little different but I was able to make it work.
Great kit! Worked perfectly on my 2022 Tiguan. The installation video was excellent, very helpful.
New cars are hard to install upgrades. This kit made it easy.
Not only was it perfect fit, the step by step wiring instructions made the job much, much easier. Thanks!
If you do not have 60% knowledge in mechanics, please see a dealer. For me, it only only took me 2 hours to install the harness. Just follow the instructions.
It was very easy to install and the support when I had an issue was exceptional.
Looks great! Can't wait to install it!
Great products! Ordered the Curt trailer hitch receiver, T-One Wiring Harness, and accessores on Wednesday; they arrved Friday, and I installed them on Saturday. Everything fit perfectly. I plan to use the hitch mostly for bikes, but decided to add the wirng harness just incase I need to pull a small trailer.
This harness was a great purchase. Install was straight forward. Instructions excellent. It is the second such harness I have installed, one on a 2018 Tiguan and one on a 2022. Great product and great company!!
Super simple to install.
Good product. Nice , easy connections. Thanks.
I haven't installed or used the wiring harness yet but the purchasing process was a pleasure as usual with etrailer.com.
The Tekonsha part works great. I own a VW and "trailer" turn signals hyperflash when car headlights are on. Yet all other light modes work fine. Turn headlights off 100% perfect. It's a VW computer thing. The Curt was worse.

I finally rid myself of hyperflash issue. I traded VW in on 22 Nissan Frontier ready to tow. Product was great but VW is a problem to wire for electric brakes. Needs an additional $xxx factory module....maybe. Nobody would help me with it. Not etrailers fault. As A Mechanic VW computer systems and wiring are very complex. Not for the novice. Dealer would not even help me with it. Never again VW. Again product was great and so is etrailer. It is a VW issue.
Works great on my 2023 VW Tiguan. The hardest part was running the power wirer under the car while on the ground.
Everything went on without a hitch! (pardon the pun). The was on-time and the video of the install was very helpful.
No complaints here. The shipping turnaround was super quick and items were packaged well.
Excellent product, almost all plug n play. Clearly gaining access to the connections and running the primary to the battery are the biggest obstacles.
Watch the videos and read the reviews before you buy. If it sounds beyond your skillset it probably is.
For me, popping the panels proved easy. I managed to not break anything. All the provided wiring reached where it was supposed to.
I followed the advice of another review suggesting that the primary be run thru the vehicle cabin along and under the trim. Then I found an access hole in the engines firewall where other wires passed thru a rubber grommet. I actually uncurled a metal hanger, guided it thru from cabin to engine compartment, connected the provided primary wire and pulled it back thru.
My vehicle’s underbody has a full length cover/shield, which without a lift would have been awful to deal with.
Again, excellent product.
Great Customer a service and follow up. Overall things work well on the Tiquan and the installation support and videos made it a breeze.
Excellent website and customer service. It was easy to find my vehicle’s hitch components and understand the installation instructions.
Desiree and George, customer service, kept me informed took good care of me.
I’ll definitely return to etrailer in the future.
I bought this for our 2018 Tiguan and it works great. The instructions were well thought out and easy to follow. Included everything I needed in materials to complete the job. I would however recommend running the main power wire through the cabin instead of using zip-ties to the bottom of the car. It provides a cleaner install and there are plenty of vides to follow for this. total time it took was a few hours taking my time with routing it inside.
Difficult to install, mostly the VW. Otherwise, works well.
Easy to use website. etrailer customer service answered my questions and responded quickly and accurated with shipping information. Happy customer...
Works great and is a fraction of the price of VW kit (which is hard to find these days). The video tutorial was super helpful...I could not have completed without it.
etrailer rocks.
Seems to work as advertised. Seems to be a quality product Install was a bit of a hassle but not too bad. I recommend watching the video for the CURT wiring. Easier to follow than the fuzzy pictures and less than perfect printed instructions that came with the Tekonsha harness.

That is not good to hear. So, typically when a fuse keeps blowing that means there is a short somewhere on your wiring circuits. Or it could be that there is an overload or there is another fault of some kind, either in something on the vehicle or the harness. This is something that can be fairly easy to find. Start with unplugging everything from the circuit. If the fuse still blows, then let me know and we will do some further troubleshooting from there.
