Installation
This custom-fit T-One connector plugs into your vehicle's wiring harness, which is located behind the passenger's-side interior trim panel in your rear cargo area. 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 flat connector will be stowed in the jack storage compartment of your rear cargo area.
It is recommended that you use a small amount of grease on all electrical connections - the plug 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.

Every time was delivered in a timely manner and in good condition. Installation for the wiring harness was straightforward. I paid a shop to put the hitch on, which I was glad I did. Overall great service nice people. Knowledgeable help

I left a detailed review for the Hidden Hitch with THIS product as part of the review because I bought it as a package deal. I will say a quick note on this product alone just for customers information. This was ridiculously easy to install. It literally just PLUGS IN to a control board, then you have to remove a small bolt and attack ground wire, zip tie the wires across to the jack compartment for easy storage when not in use and plug in a small fuse up front. I can honestly say that even someone that is not mechanically inclined or used to working on cars could EASILY install this wiring harness. A great product, great customer service. I give it 5 stars. Highly recommend this product and etrailer.com

Package was slightly opened on the side. Don’t know if someone from the delivery company was tryin to take a look on what it was or ripped open during delivery. When I opened the package it was scratched as if it was dragged on one side on a rough concrete floor.. but I guess looks don’t matter or minor blemishes on a piece of metal thats meant to haul... but maybe it’s just me. If I get something new I want to be the one to scratch it on my own. When I hear new. I think undamaged. As far as quality/install it is beefy and easy... I was able to do it solo but used jack stands to hold it in place for me. Wiring was also a breeze except for the fact that the video said to use a self tapping screw to ground the wire. I was expecting a screw included in the small ziploc bag that came with the lock ties and fuse... but other then that install was also easy. I would definitely recommend this company for its product for its price. Just minor issues that is no big deal to me. I gave you a 4 star cause there is always room for improvement.

2006 Honda Odyssey
Overall, a very simple process to install in a 2006 Honda Odyssey EX-L - however, I'm having difficulty locating a way to feed the wiring thru the Jack storage area, and out to the bottom of the van (can't find the grommet some other reviewers used) so that I can permanently hookup my wiring on the outside of the van and fed to the trailer hitch.
I'm not a big fan of storing the wiring inside the Jack Storage area, then feeding the wiring harness out thru the tailgate every time I want to use the wiring harness. I was easily able to find a suitable grommet that I fed the wiring harness thru when I owned a 2003 Honda Odyssey - looks like the 2006 has made some design changes in the rear end. I'll keep looking once my arthritic knee allows me to bend my knees.

Update to my earlier comment posted on 0813/2013. This is a follow on post for a 2006 Honda Odyssey EX-L. I located two easily accessible holes protected by a grommet that leads directly to the bottom of the van - these two grommets are located at the bottom of the storage area beneath the carpeting where the 3rd Row Seats are stored. -Simply lift the 3rd Row Seats if stored into the seating position. -Remove the rear tailgate trim piece same one you had to remove when you first installed the wiring harness.-Lift up on the carpeting that covers the bottom of the storage area for the 3rd Row Seats.-You should be able to see the two grommets left and right at the bottom of the storage area - lift up the grommet location you want to use I used the right one - same side where the wiring harness connects to the van. As soon as you lift out the grommet, you will see daylight!-I cut off the 4 pin connector to be able to feed the wiring thru this hole - you might be able to muscle the connector thru the hole if you push hard enough and will probably have to bend the 4 pin connector thru the hole - youre call. I then had to solder the two pieces back together - pretty simple process if you own a soldering iron and know how to solder. Only issue I saw with this location is to watch the wire sag - this hole location does not offer much protection for the wiring from any potential snag issues while driving if there is too much sagging in the wire. I screwed in 3 conduit-type wire clamps to make sure my wiring does not sag.At some point in the future, I may decide to just drill a new hole on the SIDE as opposed to using the existing BOTTOM hole of this storage area this storage area for the 3rd Row Seating appears to just be a fiberglass and/or plastic resin-type pan that looks like it would be very easy to drill thru - I can then go buy a suitable size grommet to cover the hole.

I used a grommet hole for the factory panel clip. Drilled it out with a 3/8 bit about 4 holes wide.. Then fed the wire through the hole.

This was just what I needed to wire my Honda Odyssey van to pull my trailer. It was a relatively easy self-install. Came with a fuse. I just had to pull the back interior panel and it was plug-and-play. Then tucked the wiring and voila - my popup camper has lights and is street legal. Very easy experience with etrailer. Highlander recommended!

I installed the hitch receiver and wiring harness without any issues, and both work well. I found the video instruction to be much more helpful than the written instructions that came with the products. I needed two new tools: a torque wrench for tightening bolts on the hitch receiver, and a trim removal tool to open the side plastic panel to install the wiring harness.

This is a great wiring kit. It is awesome that the Odyssey has a junction box that thus just clips into. The only tricky part is pulling the passenger rear panel and the threshold panel and that isn't to bad either. The only tools needed for this Odyssey wiring harness is a 10mm wrench for the ground terminal and a body panel pry lever. The instructions and pictures are clear as is the nice video. Anybody who wants to can install this harness without a problem with the clear instructions.
Easy I.

Ordered a hitch for Honda Odyssey. Received it 2 days ago, installed yesterday - easily, with the help from a friend. Everything fit just right, no drilling. The electrical part was no problem. Today used it to tow my boat in for service.
Etrailer was great. Minutes after I placed the order I received an email acknowledging the order and offering to call with any questions. An hour or so later, another email informed me that it has been shipped. Excellent job. Thanks!

- Running Lights Are Not Working On a Trailer Towed by a 2008 Honda OdysseyThe typical cause of trailer running lights not working is a bad ground connection but there are some tests you can do to determine where the problem is. First, disconnect the trailer from the tow vehicle. Then use a circuit tester such as # PTW2993 if you need one to test the connector on the vehicle. Have someone sit in the vehicle and turn on the running lights while you test the connector with the circuit tester. If the running light circuit works at the trailer connector then the...
view full answer... - Curt Trailer Wiring Harness for 2006 Honda Odyssey has Constant PowerAre the lights on the trailer actually lighting up or just the circuit tester? If the trailer has LED lights then it is more likely that Curt harness # C56161 will cause them to dimly light up. Curt trailer wiring harnesses that are powered like this one sometimes have this issue. The converter is working properly but for some reason a little power bleeds through causing this exact issue. The Tow Ready harness # 118438 does not have a history of this issue and would be the preferred wiring...

If you click the provided link you can see an install video for the # C12031 hitch. If you'll be towing with the hitch, you'll also need a trailer wiring harness like # 118438. For a ball mount, use part # 3593 and for a trailer ball use # 19256 for a 1-7/8 inch or # 19258 for a 2 inch trailer ball. I've linked to an install video for the hitch and the trailer wiring harness.
view full answer... - What is Towing Capacity of 2010 Honda OdysseyI looked up the towing capacity of your 2010 Honda Odyssey and it is rated for towing up to 3,500 lbs. For a hitch you'd want the part # 75270 which is a confirmed fit, easy to install, and has more capacity than needed. I attached an install video for more info as well. For trailer wiring you'd then want the part # 118438 which is very easy to install and is very reliable. If you wanted to do some towing you might be interested in etrailer ball mount kit # 989900. It comes with 2 ball...

This will connect to your 4-way connector and with additional wiring give you both a 4-way and a 7-way connector. I have attached a link to an installation video that shows a brake controller and the # ETBC7 controller being installed...

You will need to upgrade to the Tow Ready Heavy Duty Modulite, part # 119190KIT, which has a capacity of 15.9 amps. This wiring kit draws power directly from the vehicle battery via included fuse.

But you need to pick one out that will allow you to tow your trailer level. In order to do that you have to find out which rise/drop you need. You will need to measure from the bottom of the coupler to the ground when it is sitting level and then you will need to measure from the top of the hitch opening to the ground. Whatever the distance is will be the amount of rise/drop you need. With that dimension you will be able to check out the link I...

I was unable to find your order number, but the wiring harnesses that fit an '06 Odyssey do not have the extra plug/cap like you are showing. That said, from the photo it looks like that is just a cap for the plug, but that would be unusual because there's really no reason to have a cap on the T-connector like that.

- Would Class II Hitch for 2007 Honda Odyssey Be Able to Tow Small TrailerThe Class II hitches for your 2007 Honda Odyssey like the Draw Tite part # 36417 which is a confirmed fit have a decent towing capacity of 3,500 lbs total trailer weight and 300 lbs tongue weight. If the weight of your trailer is under those figures the hitch would be just fine. You'd also need to check the owners manual of your vehicle to determine the capacities of it as well. Be sure to stay under the lower of the two capacities. For trailer wiring you'd then want the Tekonsha kit...

view full answer... - Towing Package for a 2008 Honda OdysseyThe trailer hitch I recommend for your 2008 Honda Odyssey is the Draw-Tite Max-Frame # 75270 because it doesn't require any fascia trimming (like the etrailer and Curt might). This, as well as the other trailer hitches, exceeds the weight ratings of your Odyssey so you can be confident that you are getting the most out of the trailer hitch. Be sure to check the weight ratings of your Odyssey in your owner's manual and keep from exceeding it. To finish out your towing setup I recommend...

- Can a 2008 and a 2015 Honda Odyssey Use the Same Trailer HitchSecond, third and fourth generation Honda Odysseys from 1999-2015 use the same hitches. The Draw-Tite Class III hitch, part # 75270 would be a fine choice for both vehicles you mentioned. It sounds like you might be planning on removing a hitch from an older vehicle and installing it on your 2015. This is perfectly acceptable, but be aware that the hitch installation hardware is meant for a one-time installation only. If you reinstall the hitch on your new Odyssey, you'll want to order...

I will explain what the parts are and what they do, then I will include some recommendations of parts for your 2008 Honda Odyssey. A ball mount slides into the receiver, or square opening in the hitch. They are available in different heights so that depending on how tall the vehicle is and how tall the trailer is, a ball mount can be selected that will keep the whole rig level.

Check the trailer connectors on both sides for dirt and corrosion and clean them out. Next check the lights themselves. Many trailer lights ground through the mounting studs if...

If there is no signal for the running light circuit, then the issue is on the vehicle.

You can test this with a circuit tester like # PTW2993 for voltage on the input side of the box as well as on the output side of the box. If voltage is going in but not coming out of the box like it sounds like is going on then the issue is the box and you'd have to replace the entire kit since they are not available separately.

Havent used the wires in over a year after our move across the USA. Just towed a boat this late week and the wires all still worked perfect. Had no issues and they were in the same shape as when I first opened the box. High quality product, highly recommend.
