Installation
This custom-fit T-One connector plugs into your vehicle's wiring harness, which is in your rear cargo area, on the driver's side. You will have to remove the floor covers, cargo trays, and some interior paneling to access this harness. Once you've plugged in the connector, you will have to route the harness through the jack storage compartment to the center of your vehicle. Afterward, locate the fuse box under your hood and insert the provided fuses.
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-pole connector itself - to help prevent corrosion.
ModuLite Powered Tail Light Converter
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 bypasses the electrical routes that are used by a basic wiring harness, there is virtually no draw on your tail light circuits.

Product Great BUT would not power up....found I needed an additional fuse not mentioned in instructions or video. I have a 2018 Honda Pilot....blue wire on Honda which mates to fused black/orange wire on module had no power and therefore no power at the 4 pin connector. After spending a couple of hours trying to trouble shoot, I fortunately found another review with same problem which advised to install a 20 amp in trailer charge slot in fuse box in engine compartment. Now working perfectly. An additional 20 amp fuse in package would be helpful, along with correcting the video and written instructions. 557601

Excellent product. One glitch. Installed wire harness per instructions in 2018 Honda Pilot. Put supplied 30A fuse in fuse box under the hood. No lights on trailer. Solution: Install a 20A fuse in the TRL CHARGE position in the fuse box. For hassle free installation scroll to video at FEATURED HELP INFORMATION. First time customer. Good experience with etrailer.com price and product. 545268

Delivery was fast. Installation was straight forward with the aid of the available video from etrailer. For a 2016 Honda Pilot you will require 2 20 amp fuses to install in the engine firewall fuse box which you have to purchase separately in addition to the 30 amp fuse that comes with the kit. I found out about the 2 20 amp fuses by reviewing the Honda harness installation manual. Wish they would have included this in the harness manual provided. If they did it would have saved some time and I would have rated it 5 stars. 554973

2017 Honda Pilot
Wiring harness works just as advertised and installation is a breeze. However, the instructions failed to note the need to install 2 additional 20a fuses (not provided) for the unit to work. The one fuse they did provide and instructed to install only provides power to a wire that is not connected so it's virtually useless when installing the 4 pin flat trailer connector. The eTrailer tech was VERY helpful in identifying the issue after I did a bit of troubleshooting and sent them a photo of my configuration. Would like to see them include a flyer with all 2017 Pilot harnesses the sell alerting the customer of the need for these 2 additional fuses. The installation instructions that came packaged with the harness did not mention these fuses but the same instruction on the web site does so there was some confusion and took a couple of days exchanging emails to finally figure out the problem. I'm very satisfied with the product and the help eTrailer staff provided. 542731

This is a well made product and etrailer has always met my needs. I found that the etrailer installation video was better at showing the "how to" then Tekonsha"s supplied instructions. The pictures in their instructions are very dark and it is hard to see the vehicle features. The installation went well and as described but I found that after installing the grommet in the floor there was ample length of harness outside the vehicle but the harness inside was taught and the ground wire wouldn't reach the recommended screw and I couldn't secure the Modulite or have a view of the inline fuse. But I was able to pull some of the excess wires up thru the grommet to allow more slack inside the vehicle. Then I was able to complete the installation as shown in the video. However, when testing the system I found that nothing worked. I had seen a recent review on etrailer describing this same issue so I installed a 20 amp fuse in the TRL. CHARGE slot in the under hood box and the system works fine. This was in addition to the 30 amp fuse supplied in the kit. It is a bit concerning that only a couple of us have encountered this issue. Hopefully that is the only issue I will have with this product. 508108

To start with, the folks at etrailer are great to work with, eager to please. The product is great except that the instructions left out one important step that cost me several hours of troubleshooting time as well as having to get another wiring kit shipped to me, only to find it didn't work either. I have a 2017 Honda Pilot Touring. I installed per the instructions, including installing the 30A fuse in the fuse box under the hood. Nothing worked. Solution: I had to install a 20A fuse in the TRL CHARGE position in the fuse box under the hood. Once I installed that fuse I have the correct voltages at the 4-wire flat connector. I haven't hooked my boat up yet but I assume the lights will work when I do. 483495

Do you have a question about this Custom Fit Vehicle Wiring?
- Trailer Hitch and Wiring for a 2017 Honda Pilot without Factory Tow Package
- Yes, Draw-Tite trailer hitch # 75225 will fit your 2017 Honda Pilot. I have linked a video showing an example installation for you.
If you plan on doing some towing I recommend etrailer ball mount kit # 989900. It comes with 2 ball mounts; one with a 3/4 inch rise or 2 inch drop and one with a 2-3/4 inch rise or 4 inch drop. It also includes a 1-7/8 inch ball, 2 inch ball, hitch pin with clip, and a storage bag.
If the ball mount kit does not have the right rise or drop to tow the...
view full answer... - Trailer Hitch and Wiring Recommendation for 2019 Honda Pilot
- For your 2019 Honda Pilot the best hitch we have is the Draw Tite part # 75225 if you plan to do any towing since this has a wiring bracket built into it. It also has a concealed crosstube too which makes it less visible too.
Then for trailer wiring you'd want the T-one part # 118286 for a 7-way or part # 118760 for a 4-way. This brand of trailer wiring is our most reliable option so I recommend it highly.

view full answer... - Recommended Wiring Harness For A 2017 Honda Pilot
- The installation of all our harnesses for your Honda Pilot will be the same for both the 2016 and 2017 models. I recommend using the T-One Vehicle Wiring Harness with Upgraded Circuit Protected ModuLite HD Module part # 118760 for a 4-way and the T-One Vehicle Wiring way Harness for Factory Tow Package part # 118286 for a 7-way as both of these harnesses are a direct plug and play option that are very easy to install. In fact, you will only need to remove one trim panel for either installation....

- The T-One Vehicle Wiring Harness # 118286 is intended for use on a 2016 Honda Pilot as a direct OEM replacement 7-way for the one that came from the factory for the tow-package-equipped version. The harness plugs in at a white connector located behind a rear cargo area access door on the driver's side. Please refer to the linked photo of the connector and to the linked instructions for installation procedures.

- The Curt T-Connector Vehicle Wiring Harness # C56291 is installed and mounted inside the trunk space of your 2018 Honda Pilot, as you can see by the accompanying photo, which is from a video we did installing this connector in a '17 Pilot.
If you wanted to mount your connector under your Pilot you would not need to use the T-One 7-Way # 118286 if you do not need it. Instead you can use the T-One Vehicle Wiring Harness for Factory Tow Package - 4-Pole Flat Trailer Connector # 118760,...
view full answer... - Is Trailer Hitch Available for 2018 Honda Pilot With Spare Tire?
- The hitches for your 2018 Honda Pilot, such as the Draw-Tite # 75225, will only fit if your spare tire is 18" or smaller. If so, I recommend the Draw-Tite, which has a 2" receiver and will not require any drilling to install.
To add a wiring harness to power your trailer's lights you need Wiring Harness # 118760 to add a 4-way if you do not have the factory tow package on your '18 Pilot, or Wiring Harness # 118286 to add a 7-way if you do have the factory tow package. I've added links...

- According to the Magnuson-Moss Warranty Act (P.L. 93-637), unless the installation and the part caused a problem then the warranty cannot be voided. I recommend looking it up online.
For a trailer hitch receiver confirmed to fit your 2016 Honda Pilot, I recommend taking a looking at the Draw-Tite Max-Frame Trailer Hitch Receiver part # 75225. If you need a wiring harness then the T-One Vehicle Wiring Harness with Upgraded Circuit Protected ModuLite HD Module - 4-Way Flat part # 118760...
view full answer... - Which 4-Way or 7-Way Trailer Connector Do I Need for My 2016 Honda Pilot
- To tell the difference between a 4-Way or 7-Way Connector is to look at the connector itself and see how many pins it has. I have included a picture showing both a 4 and 7-Way for you.
The 4-Way is the basic connection for trailer lights. You have 4 pins, one controlling the left turn signal and left brake light, one controlling the right turn signal and right brake light, one for the running lights, and the last is a ground wire.
On a 7-Way connection you have the same 4 functions...
view full answer... - Recommended Brake Controller And Wiring For 2017 Honda Pilot
- For a brake controller, I recommend the Tekonsha Prodigy P3 # 90195. This is a proportional brake controller that will apply the brakes on your trailer at the same time and with the same amount of pressure that you hit the brake pedal in your Pilot. It also has a really nice LCD screen that takes the code deciphering of most brake controllers out of the equation. It has 3 levels of boost and is adjustable to your preferences.
If you have the factory tow package, then you only need...
view full answer... - I Need a Trailer Wiring Harness, What Is The Difference Between 118679 and 118760

view full answer... - Trailer Brake Controller Installation in 2017 Honda Pilot with Factory Tow Package
- Some late-model pickup trucks offer the option of a factory-installed trailer brake controller but a vehicle such as a 2017 Honda Pilot does not. In your Pilot you can use a superior aftermarket brake controller. In fact many folks with factory controllers ultimately end up replacing them since the aftermarket units like the Prodigy P2 # 90885 and P3 # 90195 work so much better.
If your Pilot came from the factory with a tow package already installed then brake controller installation...

I recommend this hitch because it has a concealed crosstube which makes it mostly hidden, is made in the USA, and has great towing capacities at 6,000 lb trailer weight. The attached picture is what the hitch would look like installed.
For trailer wiring you'd then want the # 118760 which is a confirmed fit and would give you our most reliable 7-way option.

transmission from overheating when towing more than 3,500 lbs (1,588 kg). So if the trailer is less than 1,200 you would not have to have a transmission cooler.

They both have 6" oval LED lights with a 4-way wiring harness. The only noticeable differences between the two are the wiring harnesses.

This hitch is custom-fit for your vehicle and will provide a slightly better ground clearance measurement than the compatible Curt alternative. This has a 900 pound tongue weight and 6,000 pound towing weight capacity. Because the hitch will use existing holes in the vehicle frame, no drilling is required during installation.
