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.

Just what I was looking for.Install for wire harness was quick and easy.

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!!!

Great product easy to do would highly recommend your product and your company
by: Rob02/21/2020
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

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.

Very easy installation shipping was fast product worked exactly as described only issue was removal of my Honda pilot plug the cap in the plug under the vehicle near the exhaust pipe was a real bear to get out new plug snapped right in place and everything else was super easy now I can tow my trailer worry free about my lights or turn signals,thanks for everything!!
by: Aiden07/28/2019
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

2011 Honda Pilot
"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.

This was very easy to install. I was worried the modulelite would be a problem but was very easy to install.

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.

Im happy to say that the harness still works. Have not have any problems with the harness.
by: Michael10/03/2022
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.

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 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.

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!

By following the written instructions and online video, I was able to
successfully wire my vehicle with the wiring kit provided. The components were well made and fit the vehicle connectors as described.
I would recommend this product to anyone wishing to add a wiring harness to their vehicle.

I had this installed in about 10 minutes. The hardest part of the install was the zip tying the harness under the rear bumper. Awesome installation direction. Scale of ease being a 10!! Thank you.

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.

1 year later and wiring harness is still working perfectly. We upgraded our boat and have a new trailer and no issues. Really love the cover, even in Florida salty weather no issues.
by: Tom C.05/13/2011
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.

This is my second purchase from Etrailer and I'm very pleased. Product arrived quickly and was exactly as described. Installed on my 2010 Pilot very easily and all the trailer lights work perfectly. Most difficult part of the install was removing the cap from the wiring plug under the rear bumper. Found it easier once I unhooked the plug from the vehicle and let it hang down, making it easier to access. Other than that, it's plug and play. Hope this helps.
by: Barry G03/27/2015
2011 Honda Pilot
I put this in a 2011 Honda Pilot. Very easy job. The attachment of the mounting bracket (#18144) which is sold separately was tough just based upon screwing the self tappers into metal. The 4 pin connector needs some work to go in and stay in the mounting bracket but it will does stay firmly in place.
Videos are great. I wish every company put the effort into their products and support that etrailer.com does.

2010 Honda Pilot
Have a 2010 Honda Pilot, part arrived quickly. With the Youtube video it was a breeze. I was picking up a trailer at [retailer] and actually put this part on the Pilot in their parking lot. They wanted to charge me 130 to install this 4 prong piece. Saved close to $80 bucks doing it myself.
Like most people getting the cap off took some effort at first. You really need to remove the blue clip before removing the cap. After removing the clip the cap came right off. Just snapped back in the blue clip and put it back into it's spot.
1 minor issue: the set came with 2 - 20 amp fuses' and 1 - 7.5 amp. Needed 2 - 7.5 amp fuses for this kit and 1 - 20 amp fuse. I had a spare fuse available so it wasn't too much of an issue.
by: Chris03/22/2019
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!

- Wiring Harness and Brake Controller Installation on 2010 Honda Pilot without Tow PackageBrake 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,...

I recommend the Tekonsha OEM Replacement Vehicle Wiring Harness with 7-Way Trailer Connector part # 118253 which will plug into your factory tow harness behind the rear bumper and give you a 7-way trailer connector on the Pilot. This will give you the functions to tow a trailer with brakes. If you need a bracket to mount the 7-way I recommend part # 18159 which does not require drilling to use. If...

For your Pilot you will only require the one relay for the rear fuse box to be placed in the right terminal. The 20-amp blade fuse will be placed in the top right fuse slot (1). The 2 7.5-amp fuses will be placed in the 2 top left slots (3 & 4). There will be 1 empty slot (2) between the 7.5 and 20-amp fuses....
view full answer... - Installing Tow Ready # 119491 4-Pole Trailer Connector on 2011 Honda PilotAccording to the instructions, it's not necessary to remove the negative battery terminal. By connector clip, I'm assuming that you're speaking of the protective cap on the harness under the vehicle behind the back bumper. There are two clips on either side of the cap that need to be pushed in, in order to release the cap. If you click the provided link, you can see a video showing the # 118491 being installed on a 2010 Pilot.

You might have to keep at it for a bit, but the cap should come off. Avoid using brute force like pliers, if those tabs are damaged the plug will not be seated correctly when plugged in.

view full answer... - Trailer Wiring Recommendation for 2014 Honda RidgelineYou might be the first person to request a universal trailer wiring options verse a custom fit one that doesn't require splicing! We can help though. For a hardwired harness that does not require splicing, I would recommend the # 119250KIT as it basically can fit any vehicle due to it's universal nature. I would still recommend the # 118491 though as it's going to be easier to install and not require any vehicle wire splicing.

Reese and Tekonsha are the same company. You may or may not need all of the included fuses and relays that come with either of these kits. The larger "box" fuse does not install on the Ridgeline. I have linked the instructions for harness # 118491. You can see that in the instructions that box fuse is only used on the Pilot.

If you previously installed the 4-pole using part # 118491, you've already installed all the needed fuses. You'll just need to add one additional relay in the fuse box located in the cargo area. The # 118253 will provide some fuses and a relay you won't need now, but it's always good to have spares. I've provided...

view full answer... - Trailer Wiring Harness for a 2011 Honda PilotThe use of a universal trailer wiring harness is not recommended on the 2011 Honda Pilot in part because it is already set up for a plug and play type of wiring harness such as # 118491. Otherwise you will have to gain access to the wiring leading to the tail lights and splice into them. This will likely require removal of some trim panels in the cargo area of the Pilot. Once you have access to the wiring I recommend using a circuit tester such as # PTW2993 to test the wires to determine...

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.
