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.
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
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
Charles - 07/17/2019I ordered this product for my 2017 Honda Pilot and wasn't really sure if it was going fit and work. This connection was said that my Pilot needed to have the manufactured towing package. I was not sure if it did. Well, after installation along with C-57672 4- way to 7- way RV and 4-way Flat adapter, it work just fine. The instructions were so easy to follow. I plugged it on to my boat trailer and it worked great. It was shipped 2 days earlier than it said it would. All parts were there and in good condition. Thank you Carol for your help. And thank you etrailer staff. I highly recommend ordering parts from etrailer. 651662
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
The trailer hitch you recommended, was everything you said it was going to be. The installation went as smooth and easy as possible. All the information you provided was as you said it was. All the parts and hardware was included. Thank you Diana H. you were very patient with on the phone and answered all my question and suggest all the right part. Thank you again for all your expertise knowledge. The picture attached is of the finished installation. Total time of installation was 1 hour. 592649
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
Installation was a lot harder than I expected. I have a 2019 Pilot EX-L. I had to remove more panels than the instructions said. It shows the plug right behind the panel, but you need to remove the whole side panel to get at the plug. After a call to E trailer and talking to Robert I was able to finish the job. He sent me the installation video to a 2017 Pilot which showed how to remove panels to get at plug. Thank you Robert S. 636485
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
This was one of the easiest hitch to install that I've every seen. The hardest part of the job was pulling the stapes of the box so I could recycle it. The wire harness was a piece of cake. the hardest part was pulling the rubber gromet in the factory hole. I did find the Jack for the truck.( this is a brand Honda Pilot) I had to remove it so my big hands could connect the wire Harness. Would I buy another Hitch and wire Harness from etrailer.com. Yes I would. I ordered it on Thrusday got it on Monday. Installed Monday evening before we eat dinner. 616173
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
Product worked as expected. The installation videos available on etrailer make a big difference. Makes installation so much easier. 756883
Bought a working harness for our Honda pilot, not only was it very easy to install from the instructions that came with it, but it was 1/3 cost of purchasing it around our area.. 751359
This wiring harness is very good quality and it fit our vehicle perfectly. The cost is about 1/3 of the factory harness. I installed it in about 30 minutes. 750268
