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. Powered ModuLite reduces strain on wiring system.


Features:

  • Provides a 4-way flat trailer connector at the back of your vehicle to power your trailer's signal lights
    • Compatible with 5-pole, 6-pole and 7-pole adapters (sold separately)
  • Connects quickly and easily - no cutting or splicing of wires
    • Tow harness with 4-way connector plugs into connection point behind rear bumper
    • ModuLite connects in rear cargo area
  • Includes ModuLite to ensure that your vehicle's wiring matches that of your trailer
    • Powered module connects directly to battery to avoid overloading vehicle's electrical system
  • Supplies required relays to activate functions
  • Constructed of 16-gauge bonded wire
  • Comes with dust cap for 4-way flat connector


Specs:

  • Maximum amperage:
    • Stop/turn lights: 4.2 amps per circuit
    • Tail lights: 7.5 amps per circuit
  • 1-Year limited warranty


Installation

This custom-fit T-One connector plugs into your vehicle's wiring harness. The connection point for the 4-way tow harness is located behind the rear bumper, on the driver's side. The ModuLite plugs into the factory wiring harness within the driver's-side storage compartment in your rear cargo area. Once you've plugged in the ModuLite, insert the included fuses and relays into your fuse panel as indicated in the instructions.


Once installation is complete, the 4-way flat 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 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.

After buying the Curt version of this three times in 6 months and something failing internally and curt say it isn't an issue with their product but it has to be an issue on my side with the trailers i am pulling, This right here hasn't failed once in a year. I had checked all three of my trailers and never found an issue with the wiring. This is the way to go if you have a Honda pilot and will be towing something with "trailer lights".

Product was Quality and installation instructions were good. The only improvement is when connecting the Tow Cable Harness it’s best to detach the Vehicles Cable from the frame (Pic) to release the protective cover due to there being 2 Tabs that release different ways in different directions on the Plug Cover. When I plugged the cable into my trailer’s the lights lit up like a Christmas Tree, Great Job!!!



by:

This kit was perfect and easy to install. Truly "plug and play!". With the bracket that etrailer.com also carries, I made a small mod so the original cover plate still fit and I could use the plug cap. But the kit is really all you need



by:
2011 Honda Pilot

Item arrived in a timely manner. Instructions were easy to follow. Installed in about 30 minutes. I notched the removable cover where the 7-pin RV socket would go to allow room for the wire to come over the top for a clean install.

Just what I was looking for.Install for wire harness was quick and easy.
Photos on instructions were a little dark, other than that all was very good. Customer service was delightfull and knowledgeable.
Thanks etrailer.... ;)

it was everything that was to be expected. I used it to save money from buying at the [car] dealership. I just watched the video and followed step-by-step took about 10 minutes to install. Thank you

"That was easy".. Worked like a charm. Glad I went this route instead of the dealer. Saved a lot of $$. The only thing was trying to figure out which one to get on the website. I was confused. I knew I needed a 4 point connection. My vehicle had a hitch but no harness so when it asked for a tow package I wasn't sure what to select. I ended up going with the product that seemed to be used the most and had the most reviews. I made the right choice. The directions were real clear... Getting the plug off the wire harness on the vehicle was a little tricky. You have to detach the plug on the vehicle by pulling the clip out of the hole in the frame. Then the clip thats attached to the plug needs to be removed (don't break it just unsnap it). This will release one end of the plug. Then on the other side is a little snap you have to press. Once you plug in the new harness you can reconnect the snap to hold the two connections together and reattach to the frame. I should have taken pictures. Maybe someone else that reads this could do this in the future and share.

1 year follow up - I havent used it much since last summer but the only problem I incurred were a few burnt fuses. It wasnt anything wrong with this product which I thought initially but the trailers had bad grounds. I had to test the harness on other trailers to narrow it down to the trailers. After fixing the trailers grounds I didnt have the problems again.

The Trailer Wiring Harness works like it suppose to. It was a easy and fast hook up. The price is so much less than buying a manufacture part from Honda. I would recommend buying this product from etrailer.com , it would save you a lot of money.

The product works great. My 2010 ridgeline had different fuse and relay locations than the pilot.(the same kit) 1 call to etrailer and I was well on my way. Support staff is excellent and professional. Shipping is fast. These guys really have it together.

I have a 2010 Honda Pilot and I purchased a 4 Flat wiring Harness so i could tow a log splitter.
The wiring harness was very easy to install. The printed instructions that came with the kit alongwith the video on etrailer's Product page made it a snap to identify and install the relays and fuses. The plug that attaches behind the bumper was also easy to attach.
All in all, I was impressed with this kit and will happily say that etrailer did good by me.
Thanks, etrailer!

I was able to accomplish the installation of the Honda Pilot trailer wiring harness by using the directions provided. On a 1 to 10 scale, I would rate the difficulty of this project, as an 8. Not having to pay a Honda dealer the big bucks they charge, was the primary motivator for me. I have pulled a trailer many times over the past year, and have had working trailer lights every time.

First the shipping was so fast. The part was exactly what it showed and the youtube installation video made it so easy to do. Took me 20 min to install and works perfect. Plus, the price was amazing. Only 1 local store carried this and they wanted 3 times the price.

I have zero experience with towing or hitches themselves, but I knew in order to tow a rental trailer, I'd need a ball mount and power. Luckily, I found etrailer.com and easily found this product for my 2009 Honda Pilot. After watching the great video I felt confident I could do the wiring hook-up. The product was shipped quickly and the installation went exactly as in the video and included paper instructions. I couldn't be happier - the product had everything I needed. I also bought the mounting bracket and ball mount.



by:

Great Product, Included everything I needed to have functional trailer lighting. My vehicle had a factory tow hitch installed, therefor, I was under the impression my vehicle only need the harness to connect the the vehicle to the trailer. Come to find out, I needed every single piece of hardware that the kit came with. Thanks!



by:

This works great! All plug in stuff was included, the manufacturer did their homework! The Vehicles today have a lot of complicated electronics. I was surprised about the relays and fuses needed and that I had to access two different fuse boxes but it all worked out. Just follow the instructions provided, they even included pictures! Easy install if you can read and follow instructions.

Great product! Everything was as advertised. The installation video was excellent. The wire harness was the only difficult part. Getting the connection block disconnected was very difficult. I think it needed a better explanation. I eventually got it but it took over 30 minutes of trial and error while laying on my back in the driveway. The rest of the installation took 10 minutes. A bracket for the 4 pin connection would be a nice addition.

Arrived Fast, Watched the Video, Installed in a snap, Works Great!

  • Vehicle Connector with Both 4-Pole and 7-Way Wiring Formats
    If the factory 7-way in the bumper of your 2011 Honda Pilot EX uses a round U.S. Car type connector (shown in the linked photo) then you can easily convert to the combination 4-pole/7-way connector type using part # HM40950. This combination connector simply plugs right in to the U.S. Car connector. If you instead need to hard-wire a connector you can use Hopkins part # HM48470 which includes a mounting bracket. This vehicle connector accepts 4-pole, 5-pole and 7-way wiring. It has screw...

  • Adding a 7-Way Trailer Connector and Brake Controller to a 2011 Honda Pilot
    If your 2011 Honda Pilot came with a factory tow package (have a Honda dealer run the VIN if you are unsure) then you can use Curt wiring harness # 118253 which comes with everything to make the 7-Way fully functional. For a brake controller I recommend the P2, # 90885, because it is easy to set up and use and it is reliable. You would also need brake controller wiring harness # 3070-P. If your Pilot does not have the factory tow package then the only option is to hardware in a 7-Way...

  • Adding a 7-Way Trailer Connector to a 2011 Honda Pilot without Factory Tow Package
    The easiest way to add a 7-Way to your 2011 Honda Pilot would be to use Tow Ready Custom Fit Vehicle Wiring, # 118253. Out of this kit, you would need to use just one of the large black relays and then replace the 4-Way you have with the 7-Way components in the kit. This is because the 4-Way kit you have installed, # 118491, already uses a lot of the same parts (see instructions). This will work fine if you are just looking for a connector that will provide the light functions, but if...

  • Why Does Tow Ready Custom Fit Vehicle Wiring # 118491 Include 1 Relay and Honda Wiring Has 2
    The wiring kit you selected, Tow Ready Custom Fit Vehicle Wiring, part # 118491, would just give you a 4-way connector at the rear of your 2009 Honda Pilot, only requiring one relay. The other wiring kit that we offer, Honda Pilot Replacement OEM Tow Package Wiring # 118253, includes 2 relays as it is a replacement for the OEM tow package wiring. Part # 118253 would require 2 relays as it gives you a 7 way connector. The kit that you referenced from Honda is more than likely part # 118253. If...

  • Determining Ball Mount and Wiring for 2011 Honda Pilot Towing European Trailer
    The products you need really will depend on the trailer itself. You will need to check out the coupler on the trailer as well as the wiring harness. This will let you determine which wiring connection you need as well as the ball mount style and ball size. It may be possible that you could use a standard ball mount like the # 2753 you were looking at. You would also require a ball so you could use the # 63845 for a 2" ball. Some European trailers and accessories require a Euro style ball...

    Brake controllers are not vehicle specific, you can choose virtually any controller for your Pilot and it would work just fine for you. This being said, I would recommend the Tekonsha Prodigy P2, part # 90885. This controller is very easy to set up and to use, and is one of our best sellers. As your Pilot is not pre-wired, you will need to hardwire the brake controller. This can be done by using our Brake Controller Installation Kit, part # ETBC7. You will also need the T-1 Wiring Harness,...

  • Troubleshooting Tekonsha Trailer Wiring That Is Not Functioning on 2011 Honda Pilot
    Sounds like you double checked all of the install steps of the Tekonsha kit part # 118491 on your 2011 Honda Pilot so the next thing to check is to determine if the converter box of this kit is possible faulty. To do that you'll need to test the wires that run to the box with a circuit tester like part # PTW2993. If you are getting voltage on the input side of the box but still there's no voltage on the output side of the box that means the box has an internal problem and that's the issue....

    Thank you for the question! I reached out to my contact at Tekonsha who gave me some really great insight for the T-One # 118491 on your 2013 Honda Ridgeline. Basically this kit was built for a Honda Pilot and afterwards they ended up finding out that it also fit some model years of the Ridgeline which is why the pictures are for the Pilot and the instructions for the Ridgeline are a bit vague. Since you have the 4-Way kit you actually only need 2 of the 20A fuses and 1 relay. The instructions...

  • Does 4-Way Trailer Wiring for 2009 Honda Pilot Control Trailer Tail Light Functions
    4-way trailer wiring like the part # 118491 covers all of the taillight functions for a trailer. This includes the taillights, brake lights, and turn signals. In nearly all situations the only time you'd want a 7-way would be to control trailer brakes. For a 7-way kit that fits your 2009 Honda Pilot you'd want the part # 118253.

  • Will Reverse Electric Lockout Work with a 7- to 5-Way Adapter on a 2012 Honda Pilot
    It sounds like the trailer has a manual reverse lockout feature. This means that you would have to physically go back to the coupler and move a lever or insert a pin to prevent the brakes from engaging when going in reverse. The other type is an electric reverse lockout. This works using a solenoid, such as # T4748800 or # DM5404, attached at the back of the master cylinder on the coupler. It will have a ground wire and a power wire. The power wire is connected to the reverse circuit...

This will give you the clean, professional appearance you are looking for. If a longer bracket is needed, you can use No-Drill Mount Bracket, Long, # C57202, with Mounting Bracket 4-Pole Flat, # 18144.
