Installation
This custom-fit T-One connector plugs into your vehicle's wiring harness, which is located behind the driver's-side interior trim panel in your rear cargo area. Once you've plugged in the T-connector, open your fuse box and locate the fuse positions indicated in the instructions. Then insert the included fuses.
Once installation is complete, the 4-way flat connector can be stored in an out of the way area of the cargo area of your vehicle when not in use.
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. Because most trailers run on a two-wire system - wherein the brake and turn signals are carried on one wire - the separate brake and turn signals from your vehicle's three-wire system need to be combined so they are 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.

Easy to install and $120 less than what Honda wanted to charge.
All products appear to be first class. Have not had a chance to install or test them out on the road.
did not tackle this yet.seems easy but too busy to install at this time.
The trailer hitch I purchased for my Honda minivan was very easy to install. It is very sturdy and support my cargo unit with no issues!
Product was as advertised. Installation was OK but woildnhave gone smother if we had any experience. Next time would be much easier!
Product worked just like it was supposed to. The instructional video was spot on. And, it took about 15 minutes to do.
Received the item quickly; installed per attached instructions; all works well.
etrailer provides excellent service. Delivery is always quick and products I have ordered have always been high quality.
This light module is easy to install.
Installation was easy, layed my ipad on the back of the rear seat and followed video instructions......works great and no spliced or damaged wiring to our new 2011 Honda Odyssey
Put it in my 2011 Honda Odyssey touring edition van, very easy to install takes about 30 minutes and the video is priceless. Highly recommended. etrailer is the place to buy your trailer products.
Very easy to install. The hardest part was removing the threshold to gain access. Just gentry pry up the top lip to loosen the fasteners and lift up.
Just follow the instructions for wiring and it is complete.
This product worked great and the installation video that etrailer created was spot on. It took less than 30 minutes to install and test the wiring harness. Customer service is first class at etrailer and I will purchase from them again when I need somthing. Thanks
The installation on my 2011 Honda Odyssey was simple. Most of the time was spent anxiously and carefully removing the plastic panels. I fully removed the rear cargo area panel and was able to partially detach the driver side cargo panel and pull it out enough to route the wires. The actual wiring was a snap. I didn't measure the "4 way" wire, but it was not very long. I was routing the wire out the factory grommet under the rear cargo panel. The wiring on this harness made it about to that point. I had some leftover "4 way" wire from another project, so I spliced it together inside the vehicle and routed it out and down behind the bumper. If you plan on using this same routing path, I'd recommend drilling a hole (or other alteration) in the bumper before installing the hitch.
Installed a new Draw-Tite Class III hitch on my 2012 Honda Odyssey, took me 30 minutes, no jack-up of vehicle required, no removeing or relocating of exhaust, hitch lined up perfect for quick bolt-up to frame, one man job. All so installed T-One connector trailer wiring harness very easy to install, no hard wiring, simple plug-in socket.'s to vehicle existing power panel. Even your WIFE could install this unit. Instruction's explain everything you require. Recomended 100%
Excellent product. And more importantly, excellent installation video from etrailer.com to help me install it!
Excellent product except the pigtail connector to trailer should have been a foot longer the ground wire should have been a half a foot longer
This Tekonsha T-one harness with control module really works great, is super easy to install and you can't beat the price at etrailer.
But because of a problem I had with water ingress into the control box, I wanted to share with potential buyers a different mounting solution that will avoid what happened to me.
I initially installed one of these 3 years ago in our 2013 Odyssey along with a new vehicle side connector. It worked great until last fall when our trailer lights started doing strange things. Thinking this was a ground fault I disassembled the connector and cleaned all the contacts, but it didn't solve the problem. Then I installed a brand new connector, but I still had the same problem.
Then I retraced the T-one harness and found the control module full of water and the circuit board fried of course. I installed it in a way that it was hanging down into the cavity behind the interior panel (much like another customer here shows it in his photos). Somehow, water was able to find it's way in it.
Now I installed a new Tekonsha T-one harness and everything is working great again, but I chose a different location for the control box. I used double sided tape to glue it onto the upper compartment of the interior panel. This way it will hopefully not be exposed to any water that might drip down. It is also angled slightly upward, so that any moisture should drip off instead of running into it.
The harness is long enough to allow for this with the exception of the ground cable. But a 12" extension will do the trick. I hope the photos are clear enough to show all this.
Hopefully someone finds this information useful.
The customer service was great! Both Teresa J and Odelia were very kind and helpful. They seemed to to be in good spirits and enjoy their jobs. They helped me with my order and my concerns. The draw tite hitch was easy to put on. You will need help lifting it in place since it is heavy. The video on how to install it on a 2012 Honda Odyssey was very helpful although I did need to unscrew 3 additional screws holding the bottom cover to the mud flap. I was a little concerned to find that the hitch had a few scratches and scrapes on a corner. I called and Odelia had advised me that it is not uncommon since the products arrive to their location unpackaged and piled on one another. I decided to keep it and just paint the corner with rustolium spray paint. Overall the product looks good and seems to be of good quality.
The wiring harness was easy to put on. The video was spot on.
The videos for both products are extremely helpful.
Great service and good product. This was embarrassingly easy to install. Took me about 45 minutes. Car is pre-drilled and ready to accept the hitch

I like it a lot. I have recommended it to two other people who have also now bought hitches and light assemblies from you. Thank you
Installed just like the video
This T-One Vehicle Wiring Harness comes complete with all you need to do a proper professional job, it is top Quality and very easy to install.
Everything came very quickly and was 100% compatible. Using the video for the hitch installation was a huge time save. First time installing a hitch and wiring and had it done in under 2 hours. Installation on 2017 Honda Odyssey and can confirm the 2016 model tutorial is identical to my 2017 model.
Very easy to install, thanks to clear how-to video.
Great product easy to install kind of fun!
Used references from your video to install on my 2012 Odyssey but noticed it says to place one of the 7.5 fuses in location #10 it actually goes in #11. Other than that very satisfied. Thanks "again".
