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.

Installation was simpWorked as expected.le.
I actually put my review in the mounting bracket section, great product and half the price of Honda.
Exactly what I needed and was very easy to install. Great price and
delivery time was fast. Great service. Thank You.
I've been in the automotive field for over thirty years and I thought the quality of the product was very good. The installation was straight forward. I would recommend the product to others.
Awesome product. Easy to install with the instructions. Paid for 3 day shipping and received the product the next day. These guys are awesome.
Easy to install. It took longer to mount my recently purchased bracket to the bottom of the bumper frame than it did to plug in the harness. It works like it should. It was much cheaper alternative than the Honda harness.
I have a 2012 pilot and I installed it in 20 minutes. instruction are a start but the fuses come on the harness, the relay attaches to harness and then relay has clip in the fuse box. you attach the harness in compartment and done. Then use the instruction for fuse in engine compartment. Only trouble was getting the dummy off the connector under the driver's side of the bumper. It took about 5 minutes to get it off, but once it was off the connector connected easy.
Couldn't have been any easier to install (10min). Paid for 3 day shipping to CA, got it in 2 days, and still paid half of Honda's retail price. This is my second purchase from etrailer (first was a wiring kit for my Suburban), and I couldn't be more impressed with the accuracy of the installation instructions and the high level of customer service at such reasonable pricing. Very rare to find these days. Thank You!
The website was very helpful for selecting exactly what I needed to install a wiring harness on my 2012 Honda Pilot. Different parts are required depending on how your Pilot is equipped, and if you need an RV or flat boat trailer connector. The website made that clear so I was able to order the correct parts kit. Installation was simple. Although the installation directions are a bit vague, it isn't difficult to figure out what to do. In my case, it was pretty much just plugging things in. Actual installation time was probably 20 minutes. Customer service is responsive. I'm glad I found this company and I will use them again.
I waited since Nov’11 for this wiring harness and it was worth the wait! This is the 3rd wiring harness I’ve purchased from E-Trailer and it was the simplest installation by far. I expected an hour to install (based on the OEM parts installation available on-line) however it took me literally 15 minutes! My only caution is that the installation instructions don’t come close to completely explaining each step but because it’s so simple, it really wasn’t even necessary to refer to the instructions. Just use them to point you in the right direction.
Thanks again E-Trailer!
I had tried buying parts for installing the electrical connection on my Honda pilot to be able to tow my camper, but was not able to get the right combination of parts or figure it out. When I ordered from etrailer, I think I also talked to them on the phone – I got the package of parts and instructions that I needed. So basically, they solved my problem.
Well made and worked without any problems.
The tab on the plastic control box to lock it into the square hole in the Pilot mounting bracket had to be filed down some to get it to slide into position. The printed directions were tough to read; however online videos were very helpful.
The installation itself was easy, once you find a You Tube video to walk you through it. etrailer.com has some great instructional videos which saved the day. Not the fault of etrailer at all (as a wholesaler), but the instructions themselves were horrible, missed two critical steps in the process.
The produce was as listed and not only was a perfect fit, but also very easy to install. The shipping was fast and the video showing the installation was very helpful in making the decision to purchase this produce. I highly recommend this company.
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.
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!
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.
2012 Honda Pilot. Seems expensive for what you get (maybe not), BUT it worked great. Easy to install. Follow the excellent video and it won't take 10 min.
Super easy installation! Just watch the video. Can’t wait to tow our boat!
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.

Thanks Arnold for posting this...i didn`t see the second fuse box either ...your posting saved me a bunch of time
The trailer harness is perfectly what I needed, great quality
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.
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.

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!
