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. Circuit-protected converter guards against shorts.

Installation
This custom-fit T-One connector plugs into your vehicle's wiring harness, which is located behind the driver's-side and passenger's-side tail lights. You will have to remove the tail light assemblies to access this harness.
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.
Circuit-Protected Tail Light Converter
A tail light converter 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. The tail light converter combines 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.
This converter safeguards itself and your vehicle against possible electrical shorts and overloads with integrated short circuit protection. Just install the connector as indicated and rest assured that the wiring system of your vehicle will remain feedback-free.

This fit a 2006 Ridgeline RTS perfectly. One year in it's still working like a champ. I used this to replace another vendor's tow harness which quit working after several years of service. Cheap, easy, does what it's supposed to do.
Even though the item I bought was not delivered to my house, the rep said it was delivered in the mailbox. Didn't expect that but overall service, delivered time, and the item was more than satisfactory.
Great towing harness. Incredibly easy to install and worked right off the bat. I especially like the dust cover for the plug itself- it fits snuggly to not fall off and has enough slack around the collar to loop through the hitch loops and hold the plug high off the ground. Highly recommended
Great product, easy install, was delivered fast! Just what I needed for our first camping trip with the Ridgeline.
The product is perfect and amazingly easy to install. I’m not a mechanic by any means but I did this VERY easily. But as good as the product is, the instruction video is simple and easy to understand and that is what made the project perfect in my mind. I’d recommend this solution a million times over.
OK, first off, the company sent me the correct item......easy to install, worked as it should....for about 7 months.......then caused a short that basically immobilized my truck, not allowing it to change into drive gears......so, after numerous attempts pts to discover the reason, I was asked if I had done any electrical work on the truck......put a test on the system and discovered a short in the trailer wiring harness....disconnected the harness and the problem was resolved....the connection had corroded at the left taillight and caused the fuse to keep blowing.....not the company's fault....just one of those things....will not buy this make, model,item again....but will do business with this company again......hence the reason for the stars.......
The tow wiring harness for my '06 Ridgeline arrived as promised. Instructions included in the package were so so, but there were YouTube videos that were perfect. Installation was difficult because I wanted the wires routed in protected locations. The right tail lamp wire almost didn't reach because I couldn't get the large connectors through the most efficient route/holes. It just did make it. I also needed more of the large black cable ties. Overall, I would give the product a B+ and the seller an A. No picture because its all buttoned up, so it looks stock.....

Hi David were you able to actually get all the wires routed out of the way of everything - and not exposed during normal use to the vehicle ?? Im curious especially about the way the wires have to cross to both taillight assemblies ?? Please let us know ThanksDaryl
First time ordering from E-trailer, this was an outstanding experience. I ordered a direct fit wiring harness for my 2013 Honda Ridgeline the product shipped on time and the ease of following step by step instructions made the install very simple. I would not hesitate to order from E-trailer again in the future. Thanks, Greg G.

Everything is still great with the harness, absolutely no problems. I really mean it when I say this is a simple and easy install item. I really appreciate the follow up and thanks again for a great product. Greg G.
This was another easy product from etrailer that I have purchased and installed myself all within one hour the instructions are simple & accurate but if you need further information just go online to see their videos this is a class "A" outfit to deal wit hand purchase from. They have my business from this day forward great products, great delivery and easy to install by DIY folks...

Everything is working perfect and thank you for the follow up. I will be buying more when the time comes that I need something you carry and I recommend you to all of my friends and colleagues
Routing the wiring wasn't too difficult. Trying to get the passenger side to plug into the tail light harness was a bit of a challenge, until I removed the factory spacer inside the plug. All the lights work fine. I'll give another review after I install the hitch.

Harness is working great with no problem. Its a perfect fit for my truck. The 7 way and 4 prong plugs work fine .
I buy Hopkins Plug-in wiring harness with 4-pole connectors. Good product, simple, great instructions. Use for one year, have no problems.

Working great, use two years, run 70-75 mph . Good trailer.
Amazing service! Ordered a hitch and wiring for a 5 year old truck, and they not only had them in stock, it they were delivered free in 3 business days!
Best internet ordering experience I've ever had!

I love it. Perfect fit, easy install, works great!
I recently acquired an eTrailer Plug & Play Wiring Harness (#118400) to complete the 4-7 Electrical Connection for a Reese Trailer Hitch which had been previously installed on an ‘06 Honda Ridgeline Truck. The P&P Wiring Product was as advertised and the eTrailer Online WEB site greatly facilitated the acquisition process. The Iinstallation Instructions included in the product package were both concise and clear. Additionally, the Supplemental Online Videos further enhanced the visual concept of the proper installation procedure. Note: However, rather than using the extended “clamp-on” bracket to mount the 4-7 Electrical Connection Plug, I altered the standard 90-degree Mounting Bracket to a Closed Angle of 75-degrees which allows the back of the 4-7 Electrical Connection Plug to neatly fit between the round tubular Reese Trailer Hitch and the frame cross member whereby completing the installation without precariously extending the Mounting Bracket or exposing 4-7 Connector and the associated wiring as a low-clearance hazard. I highly recommend this well designed produce.
I’ve been an etrailer customer for 10 years because of their customer service & easy to use website.
Every hitch, wiring harness or accessory I’ve installed on vehicles from 1998 to current has never been an issue.
When my sons truck died before his hitch set up was installed their return policy was simple.
The wiring and connections were complete and solid, the length of the wiring was adequate, the zip ties for holding the wiring in place were only 6" and needed to be at least 11" for my Draw Tite trailer hitch installation.
i had to buy a bag of black 11" zip ties to complete the job and make it look solid, a zip tie can always be cut off if its too long.
The directions were clear and straightforward, it was a nice Tekonsha product, i have used a Tekonsha brake and trailer harness before and i am confident i will get many years of use from this installation.
Hitch is on, didn’t fit perfectly but it fit
Had a problem installing but after speaking with customer service I learned it was a vehicle side issue. Etrailer was absolutely correct and their instructions enabled me to solve the problem in 60 seconds. I appreciate that. Otherwise this product was a snap to install and it is working nicely. Installed on a 2008 ridgeline needing a taillight converter between vehicle and 7 blade rv. The passenger side wouldn’t plug in. Turns out when I pulled the vehicle connectors apart a piece from the male side was stuck in the female side. Pulled that out and put it where it belonged and good to go. Who knows how long it might have taken me to figure that out on my own.
This is a fairly well designed product but definitely needs some improvements. The wiring needs to have a protective sleeve/covering installed over it before installation or else the wires are totally exposed to chafing when routed along the body, frame and hitch. I bought protective sleeve material for less than $5 at Home Depot.
The other needed improvement is something other than double sided tape to attach the control unit to a bare metal surface. I'm not at all confident the tape will last the life of the vehicle. I used multiple zip ties to ensure when and if the tape fails, the control unit will not be lost.
I would recommend this product and the service at etrailer was excellent as usual.
Top notch products, top notch customer service! Very happy with the overall quality of the items purchased. I must also mention that my purchasing these items from etrailer.com was probably the best ever online experience I've had in many years. Awesome customer service, fantastic communication! Kudos to the online sales team.
Wiring worked out great, went on with ease and came with easy to follow step by step instructions. no wire cutting no splicing! just plug in and its ready to use

After one year, I’m still towing my boat around and everything works perfect! I will definitely be purchasing again on any future vehicles. Highly recommended!
The installation took me two hours to complete. The video and written instructions were helpful but neither addressed all the unforeseen problems encountered. First of all, the process for disconnecting the wiring plug from the clip on the truck body on the driver's side of the 2007 Honda Ridgeline is different than on the passenger side. On the driver's side of the Ridgeline you have to depress the locking device and pull up to disconnect the plug. On the passenger side you must depress and pull down. I also had difficulty attaching the T-Connector Black Box to truck body. The wiring for the Black Box is so short that I had to lay on the ground and extend my arm up a narrow cavity and attach it the box to the body by feel. I expect that the reviewer who indicated that they installed the wiring harness in 20 minutes had some prior experience installing this wiring harness. A person installing one for the first time will need more than their lunch break to complete the installation. That said, the new wiring harness works great and is a big improvement over the cut and splice routine. I would buy it again.
Shipping was quick and cheap, and installation was a snap. The instructional video makes this a breeze. I only wish I had installed it sooner!

I sold the truck shortly after installing the wiring harness. It was super easy to install, though.
I had 2 problems installing it. First your installation video needs to show mounting the box part as low as possible with the 2 sided adhesive. I ended up having to go back and lower it so that the wires were long enough to reach the passenger side tail light plug. Second, there was a thin rectangular piece of plastic around the outside of the inside of the connector for the stock tail light to plug into. It took me some time to figure out that I needed to remove it so the tail light plug would go all the way in. Very frustrating. I only figured it out by comparing the right side to the left side connector.
Installed with a Hidden Hitch. The wiring harness took about 20 minutes, which included extra time routing the harness. The video was helpful in how the factory plugs disconnected from the body clips. Could have used a couple of longer zip ties for securing the harness to the hitch in more areas, if it did would be 5 stars.
Great product! The trailer wiring harness for my honda Ridgeline, ordered a new one from etrailer.com Delivered quickly, installation was very easy, works great, great product, and service. I would buy from them anytime
