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 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.
Circuit-Protected Tail Light Converter
A tail light converter 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. The tail light converter combines 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.
This converter safeguards itself and your vehicle against possible electrical shorts and overloads with integrated short circuit protection. Just install the connector as indicated and rest assured that the wiring system of your vehicle will remain feedback-free.

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 - no cutting, splicing or tapping required. Circuit-protected converter guards against shorts.The wire harness worked great simple to plug in and go. I watched a video of installation and once I got into actually installing the harness it was super easy. Great quality and no cutting and splicing. Awesome product.
have bought 2 "plug n play " wiring harnesses from etrailer and am very pleased with my purchase. Very easy to understand instructions and easy to install and durable
Super easy to install! Honda Fit 2010 - ultra easy, the connectors fit exactly as needed. The length of wire for inside the car was adequate. Took only about 20 minutes to install. Highly Recommend this unit for your Fit. Super happy, this was the easiest light harness install ever, and I like that I don't have to splice into the original wire harness, this could be replaced or come out at any time.
The wiring harness was easy to install and has functioned flawlessly. I forget it's there when not in use.
After watching the installation videos I was a little concerned about how to route the power wire to the car battery. It turns out this wiring harness doesn't need a power wire. No need to cut/split wires either. Just unplug the connector from the rear light assembly, plug it into the wiring harness female connector and then plug the wiring harness male connector back into the light assembly.
The whole process took me about 45 minutes.
This went on a 2012 Mazda 3 hatchback with regular light bulbs.
These are great. I used to spice wires. Never again, these are truly plug and pay and are worth every dollar. This is the fifth one I have installed for friends and family.
Tom - 04/28/2022Best harness for a car I ever bought and works perfect. I bought the hitch also an installed myself as I have before. Video helped me removed parts under this newer Civic so it was simple. Best customer service too because I had ordered the wrong riser for the hitch ball and the woman called me to tell me an re-did the order so it all arrived right and showed up in about 4 days !! Amazing company to say the least an was not my first purchase by no means. AAA+++
Bought this product about a year ago and still working immaculately. Couldn't be more pleased! Hookup was simple and diagram was very explanatory. Would reccomend to anyone! Thanks, eTrailer!
Alex H - 01/06/2018Easy installation even with the previously installed remote braking system I installed to use the Fit as a tow behind our RV. I don't think it took 20 minutes start to finish.
etrailer sure has made a fan out of me! The customer service has been fantastic - very friendly and helpful. The Curt receiver hitch I've installed on my Honda Fit is clearly top-notch hardware, and the instructional video made installation a snap. Many thanks!
Install of wiring was fairly easy, made harder because I'm way worse at this than I think I am. Hardest part was figuring a place to stick the module, and finding something to stick it with. Box says it comes with double sided tape, but mine, at least, did not. Best to have some sticky stuff on hand just in case my experience is the norm, and not the exception.
Literally just unplugging wires and plugging them back in, but in a better, more different configuration. Lights work. I know because I tried it.
The wire the 4-pin connector is on is long, but maybe not long enough? It's long enough for my use case, but I can definitely see a longer trailer tongue or a shorter trailer cable causing an issue. A longer cable would be nice, but I'm sure a 4-pin extension would suffice as well.
Every other cable/wire is more than long enough, so no issues with getting it across the trunk of the car to the other brake lights.
4 stars, because of the lack of included (per the box, anyway) double-sided tape and a just-barely-long-enough cable could be a foot longer and stop worrying me. Quality otherwise is good.
I received my Tekonsha trailer wiring hitch for my 2011 Honda Accord EX today and had it installed in about 15 minutes. Plug and play and with the video link that was provided it was easier than I expected. I had to deduct a star only because the time my order was placed until the time it was picked seemed unnecessarily long considering it was in stock. I will likely order one for my girlfriends 2014 Honda Pilot next.
A year later and it is still working great. Install was easy.
The wiring harness was simple to install, but only after watching your video at Etrailer.com. The printed instructions were somewhat lacking. My Honda Civic has 4 light bulbs in each taillight. Instead of the instructions telling me to look for the brown wire, why not just show a simple diagram of the 4 bulbs and say "connect the yellow wire to bulb A(see diagram)? I got it connected and it works well. My kit did not come with the double sided tape to secure the box in the trunk. It came with a screw, but I was not willing to drill another hole in the car. Double sided tape works well.
Mike C - 08/25/2016Bought this at the same time I bought my hitch and hitch bike rack. figured if I was installing a hitch I might in the future haul a trailer and would need lights. later bought a hitch mounted cargo rack and added lights. boxes would cover or block my tail lights of my car, so I added lights to the cargo rack. Works great. Thank you.
Gabriel R - 04/18/2018Install went off without a hitch (no pun intended). I jacked up the car, threaded the fish wire, all in all pretty simple. I actually did it on my own and it went well. I was under the car an braced the bar up, was able to get one of the nuts on and put the other two on to hold it into place while I finagled the other side into place (the passenger side outlet on the muffler was kinda in the way). I was able to get it on easily but tightening the last nut (closest to the back of the car) was a bit tough because the hitch frame gets in the way. Overall, it was simple, it's all tightened down, and now we can tow a trailer/cargo/whatever!
Thanks etrailer, your prices beat anyone on the internet and Uhaul by at least 100 bucks.
Shawn P - 06/09/2014A competitor wanted to charge me $70 to install a similar product on top of the price of the wiring harness. I purchased this product for under $50, watched a video showing how it is installed on my exact vehicle, and spent 10 minutes installing it. It works perfectly. I couldn't be happier. A+ for etrailer!!
Chad - 09/28/2015Arrived quickly,and installed quickly and easily. I'm a satisfied customer.
Thanks Nicole for helping me out getting everything squared away!
Quick shipping all the way up to central Alaska!!!
Already mounted took no time at all!!!
A+
I bought a draw-tite receiver, wire kit and ball for my 08 Accord... everything fit great and had great communication with etrailer folks. I was totally satisfied with service, delivery, quality and
performance of my product.
I'm buying from them again soon for our new Acura MDX
Tim G - 02/02/2015Great product! Installed quickly and exactly as described.
Hitch and wire harness hooked up easy to do picked up trailer yesterday works awesome thank you
Mark M - 04/17/2019I received my trailer harness by US postal mail on the third day after I ordered it.
It took less than twenty minutes to install. Simple and easy. Most importantly it was the right harness for my 2006 Honda Civic.
Billy J - 10/18/2017Installed hitch and wiring harness in a 2014 Civic sedan. Be very sure to specify exactly the correct car when ordering since the fitments are very specific--as I found out when I ordered a harness for a Civic without being sure to get a sedan's harness instead of a coupe's! E-trailer was very good to immediately send me the correct harness and accept back my erroneous order.
The hitch is a two-person installation. I did it by myself with an extreme amount of effort to hold the muffler out of the way while threading the attachment bolt above the muffler. Three hands are essential--or else a lot of wood blocks and fine-grained metal bending. Once attached it is a very solid hitch and it is nearly invisible below the back end of the car. Yet the hookup has plenty of access for a trailer.
What nice people to deal with. My order arrived ahead of schedule. It only took me about 30 minutes to install the wiring. Everything fit perfectly. A great product. I would recommend this company for any of your trailer products.
