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 rear threshold plate, trunk liner, and 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 connector will be stowed in your 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.
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. This unit will also ensure that your trailer's lights illuminate fully, even if your vehicle has pulse-width modulation (PWM) wiring.

In the spring of 2021 I purchased and installed a Teckonsha trailer wiring harness in our 2017 VW Tiguan. The instructions were easy to follow and the installation was straight forward - taking approximately 90 minutes to complete. The wiring has worked flawlessly. I would recommend this product.
I purchased this product for a 2017 VW Tiguan. I had originally ordered and installed the Curt Wiring Harness for this same vehicle but there was a problem with the module not functioning correctly when the headlights where turned on. I returned the Curt product and ordered this Tekonsha. It installed in no time at all and works perfectly. Having the opportunity to actually physically hold both products in my hands I would say the Tekonsha looks and feels "beefier" compared to its Curt counterpart. It also comes with a 15 amp breaker compared to the 10 amp breaker the Curt offers. I would recommend this product.
I watched the install video and knew right away I was going try interior routing the power wire because I don't have access to a lift. I found a grommet in the firewall where I think the clutch pedal would go. I was afraid I might run out of wire routing it this way. That didn't happen. Had about 3 ft leftover. Everything else went just like in the video. I ordered the tester they used to check my work. Success!!
Easy install. Plug and play. Watched video and followed directions. Works first time. Uhaul wanted $389 plus tax to install hitch and wire lights. Cost me $120 to complete job in about an hour.
Super useful and amazing, was a plug and play package basically. Will definitely be using this website/company for everything I can. Came super fast and well packaged
Another great hitch and wiring. Installed on Tiguan already.Takes 15 minutes, wiring takes 30 minutes. Still towing 25 yr old aluminum trailer I built. I will add a basket for gas cans weld one up or buy one? Don't know yet looking through junk pile for steel. Should last until I get hit again, the hitch will help in an impact. Last one on Camry took 45 mph hit from rear stopped at light. impact bent the frame totaled car. will re -cut and weld the old hitch into something else.

Dt - 12/20/2021The T connectors were awesome!Plug in and snap your done! The last wiring job I did dealt with splicing thin wires was a nightmare,this kit was so much easier! I do recommend a vehicle lift for routing the main power wire to battery,crawling on floor was not fun.
Used this many times in the past year and haven't had any problems with it. Very well designed system!
Both the hitch and the wiring harness fit well and installed with no issues.
This unit provides connection to the trailer lights. The VW, like many modern cars, have added complex lighting circuitry to keep the driver informed of a blown bulb, which means a simple hookup to the trailer lights is no longer possible. This unit provides separate power for the trailer lights, thus keeping the VW system from thinking there’s a problem with the vehicle lights. Once hooked up, it worked great for my small trailer (regular tail/stop/turn lights, plus 4 more marker lights). Installation too nearly two hours, most of that trying to figure out how to remove various plastic pieces from the rear of the car. First side took me over an hour, second side much quicker as I learned the tricks. The lights connection comes from the back side of the car’s two tail lights, with a connection you plug in without any cutting or changing the vehicle wires. Then you need to provide 12v power to the small black box that this kit provides for trailer light control. The instructions call for running a wire (provided) up to the battery, but our ’15 Tiguan has a power plug in the rear cargo area so I elected to draw 12v power from there. Only downside is that the power plug is only hot when the vehicle’s on, so if you park the car and put on the flashers then the trailer lights will not be flashing. When the car is on, everything works perfectly. I installed the trailer wire pigtail in the right side wheel well, so I just open the hatch, pull the plastic cover panel, run my trailer pigtail to the trailer and shut the hitch. When not in use, the wire and the draw hitch ball mount, plus a pair of gloves, are hidden behind the plastic cover. Overall, a great bargain compared to the cost of the VW unit!
Product worked well for about 6 months and now the trailer lights stay on the whole time it’s plugged in. Have to unplug the lights in order to get them to go off
Victoria B - 09/23/2019The wiring harness arrived quickly and was complete. The etrailer video was clear and showed all of the steps necessary to correctly install the wiring. It is really time-consuming to run the power lead to the battery without a lift for the car, but it can be done with patience and some jacks. I am a novice at any type of auto work and I got it done in a couple of hours. Great product and great directions!
I purchased a trailer hitch and wiring kit for my VW Tiguan on Friday and it arrived on Monday! In the description it stated 20 min for hitch installation and 45 for the wiring kit. The hitch was on in 10 minutes, but the wiring harness took 3 hrs, and i still have a few pieces of my car to put back together. As far as quality, the pieces look great, but haven't been put to the test yet.
The wiring kit was easy to install. No cutting or splicing was reqired. It connected to the existing car harness rhrough the taillights. By watching the existing video from your website upfront, I knew what I had to do. Very good product.
Overall this is a good product that’s simple to install. I didn’t give all five stars because the yellow wire that crosses the back of the car is not long enough and had to be extended. the quality of the included splices are laughably poor. There is room for improvement on the flat fire harness to to the hitch as well. There isn’t a good way to get the 4-pin connector that goes to the trailer out of the vehicle included. You really have to cut it off and splicing it back in; the instructions prefer to gloss over this part and just vaguly say you need to get it to the hitch area. I went though an existing grommet in the floor on the passenger side for the backup light and then used a pluggable connector I purchased locally. Shipping this harness with pins installed on the flat harness so they can be pulled though the grommet and then inserted into a connector would be a very simple solution.
Great product
etrailer is my new go-to for EVERYTHING tow related. Not only do they carry a great selection of QUALITY parts, the prices are as good as anywhere on line PLUS they give you detailed video tutorials so you can do it yourself!!!
DHarperWV - 05/08/2020I have not installed yet. But have installed the same unit on a past vehicle. This is the best plug and play unit out there period. And etrailer always offers the best products to choose from
Excellent service. Contacted every step of the process by a representative from e trailer. Will use again. Thanks
the back was simple once we got the tail lights out, wish vw would run a power wire at the factory !!!!!
I’ve bought a couple of trailer hitch receivers and 3 wire harnesses from etrailer Never disappointed and always great delivery!
You guys are the best. Great customer service and fast shipping. You my go to for parts
Trailer lights wiring kit was "as ordered" & install went smoothly after watching the video online (hard-copy instructions were marginal at best). Seems to get the job done so far.
DJ - 08/28/2017 DJ - 08/28/2017Worked great. BUT...you really cannot install this without a vehicle lift. I tried it with a floor jack & could not do it. Had to borrow my brother's lift to do it.
