Installation
This custom-fit T-One connector plugs into your vehicle's factory tow package wiring harness. The connection point for the 4-way harness is located behind the rear bumper. The converter plugs into the factory wiring harness in your cargo area, on the driver's side. The included relays then plug into the converter harness. Once you've plugged in the connector, insert the included fuse into your fuse panel as indicated in the instructions.
Once installation is complete, the 4-way connector will be stowed beneath your vehicle, near the trailer hitch. A mounting bracket (sold separately) is recommended to keep the connector secure.
It is recommended that you use a small amount of grease on all electrical connections - the plugs on your automobile and the 4-way connector itself - to help prevent corrosion.
A ModuLite power module is built into this T-One connector. Because most trailers run on a 2-wire system - wherein the brake and turn signals are carried on 1 wire - the separate brake and turn signals from your vehicle's 3-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.

Quality parts , Good instruction video for help in the installation
Installation went smoothly
Only difficult part was the dummy cap on the wiring plug at the rear bumper, kinda difficult to remove
As for the parts and instructions, flawless
Thank you for providing the parts that I needed
This product worked perfectly for my 2013 Honda Pilot. The directions were crystal clear and the installation was straightforward (easy). The process may have taken 30 minutest to complete, but I was not rushing.

After a year, this product has been solid and held up to multiple trips. Thank you!!
I am extremely satisfied with product. Took me less than 30 minutes to install. I will admit I watched some [online] videos about installing this product before, therefore I already knew what I was doing. Hardest part was to remove safety cap underneath the rear bumper to connect wiring together, however it’s a Honda difficulty, not etrailer one.
Thank you very much. Tested, it’s working excellent.
Super easy installation! Just watch the video. Can’t wait to tow our boat!
This wiring harness was the perfect fit for my 2014 Honda Pilot. The tail lights on my trailers work perfectly. Best price and best service! Thanks!
Worked perfectly. Your installation videos are a game changer!
This wiring harness was very easy to install. Took me approx 20 minutes. The price was a bit higher that some of the other wiring harnesses but ease of installation is well worth the extra money spent.
Amazing. Everything fits perfect. No cutting no hassle. This was a missing piece to my 2014 pliot ex-l. I thought the pilot came ready to just hook up a trailer and go. But come to find this is what was missing. I got on the phone with etrailer on a Sunday afternoon. Lady was really nice and answered my questions. The only thing I would like for there tp be free shipping with no price minimum.
Easy install, great video to walk you through the steps!
My wiring harness works exactly as is should. A very nice product, indeed.
Works like it's supposed to, which is the best part. No surprises. Instructions were easy to follow and installation encountered no major hiccups.
The install was delayed, stalled, waylayed and stopped because of the EVIL connector cap ( see picture ) that would not come off.
Fantastic product. It is litterally plug and play. I don't know the technical names for the pieces included, but I will try to explain a couple of important parts to the install. *1. For the the install of the single colored pinkish fuse. There are TWO fuse boxes located under the hood. You are looking for the one located right behind the radiator at around the mid point. It is smaller than the obvious looking fuse box located to legt, above the wheel well. That had me stumped for about 5 minutes. **2. Large black cable with the white plug end on one side and black plug end on the other is next. The kit comes with two loose black fuses. those plug into the the BLACK end to the cable mentioned above. There is a image of the auxilary panel you need to remove that comes with the package. Located behind the rear passenger, driver side. Once you removethe panel you will see the matching white end plug. about a good 8" straight back. I used a flash light, the inside of the panel is pretty dark. I didn't tie it down my hands were to big to get in there and do all of that. FYI,Does not rattle or make any noise. ***3. Now the tricky part. There is a gray cap (matches the the gray pug located on the final cable) that needs to be removed from underneath the rear bumper, driver side. Remember, you are laying down and looking up. There is a small lever located on the gray plug. I belive it is located on the back side of the gray plug. You need to hold the small lever down and slide forward at the same time. After you plug in the last cable. You can try to zip tie the cable on the bumper. But I was not able to locate any secure spots. I just snaked it around, and tucked it in behind the hitch. Hope this helps, oh and I am no english major. So sorry if my grammar offends anybody hahaha.

I too love this aftermarket plugplay system. Installation took all of 30 minutes only because I am old and it takes time to get up and down from the ground! You will need a flashlight, straight bladed screwdriver and nothing more! The only other items needed are WD40 or PB Blaster to used to lubricate the cover on the grey plug behind the rear bumper. This will make it much easier to remove and a couple of small dabs of dielectric grease for the plugs!

Thanks Arnold for posting this...i didn`t see the second fuse box either ...your posting saved me a bunch of time
The wiring harness number 118558 for my 2012 Honda Pilot went together pretty much as advertised with two exceptions. When the access panel is removed, there is a bracket that the black box should slide onto. I had to file the bracket so the black box would fit. Not a big problem. The real big problem came when trying to remove the dummy plug under the car. After much wasted time and energy, I finally pried the clip loose from the frame and took it apart. I then removed the dummy pug quite easily, inserted the 4 plug harness fitting and reinserted the clip back into the frame. This step should be included in the instructions as the dummy plug CANNOT be removed without that clip being taken apart. Also, the mounting brackets # 18144 and # 18140 are not needed. There is a molded 4 plug bracket as part of my plastic bumper.

Hi Oscar C - can you upload a pic of this mounting location? Would love to see your installation. Thanks
The wiring harness (Item: 118558) was very easy to install in my 2013 Honda Pilot. I also purchased the 4-pole flat mounting bracket to make my installation simple and neat. Instructions included in the kit clearly identifies each item in the kit, and which connectors to connect to the factory pre-wired connectors.

Hi Bill - Where did you mount the bracket? Can you share pix? Thanks.
Package included everything required for installation. Instructions were clear.
Product is excellent, directions are very weak! The web site picture of kit shows the black box plugged into the grey plug on harness but it is not delivered that way. Directions state to plug black box into access opening in rear driver side access. if I had not gone to the web site and saw the picture there, I would have been lost, you have to plug black box into grey plug on harness and plug the white end of harness into access plug. There are no directions on where to plug in relays I had to find that myself. I did post a video on YouTube under etrailer 2012 honda pilot wire harness.

Great video Victor, Thanks! Etrailer should comp you!
I was certainly pleased with the staff and their expertise on answering questions on the product and the efficiency of the delivery shipment. The product was easy to install and managed to eliminate the problem I had with my new vehicle with LED lights and connecting to my trailer which had the old lights. The result is the product is working great and I have confidence in etrailer products and staff. Thank you.

One year after installation and all is well.
Super simple to hook up hardest part was getting the grey cover off other than that 10 minute install half the price of purchasing in town too great product

Perfect
The most time consuming issue was removing the cap from the HONDA PILOT harness connector. The e-trailer wiring harness installed just as advertised. Highly recommend.

Works great, use it all the time.
Ordered the harness on Friday night, got it on Thursday, and had it installed and functional within 30 minutes after I opened the box. All the parts fit correctly and the control box even had the right tabs to mount where the factory unit mounts behind the panel. VERY pleased in all regards,

It has continued to work correctly - I could not be happier with my purchase.
Got this for my 2014 Honda Pilot. Worked great. Entire install probably took 20 minutes.
The longest part was getting the factory cap off of the grey connector under the bumper. Took a while to realize there were two clips that needed to be pressed. One on the bottom and one on the top.
Other than that this was a great product at a good price, and worked like a charm!

Thank you for the follow up Rachael. Everything is working fine with the harness. No complaints.
Product appears to be of good quality and I'm sure will work well, if I get them installed correctly. Installation instructions are absolutely terrible. Instructions for mounting the harness say to "locate" items, but doesn't say what to do after you have located the part. Instructions for connecting the flat plug are better. Picture with fuse installation instructions does not accurately depict my fuse box. Parts are included which are not identified and I don't know if I am supposed to install them or not. Etrailer staff was friendly and I know they can do better.

If you are referring to the two additional black relays, these are installed in the empty black plug on the harness section that is attached to the black converter box. There are slots for both relays on this plug.The box-style fuse included with the kit goes in your secondary under-hood fuse box in the slot labeled Trailer Main. Check your owners manual or the underside of the lid of the fuse box for a labeled diagram of the slot functions. Apart from that, it looks like all other mentions of locating connectors are just followed by plugging in the matching connector for the harness. Let me know if you have any other issues along the way.
The installation of the wire harness could have only been easier if I had little boy hands! The space Honda leaves for harness is kind of tight. It took me longer to collect a few tools and something to lay on than it did to actually install the harness.
