Installation
This custom-fit T-One connector plugs into your vehicle's wiring harness, which is located behind the driver's-side interior trim panel in your rear cargo area.
Once installation is complete, the 4-way flat connector will be stowed in an out-of-the-way location within your 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.
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.

I just installed the hitch and wiring harness this morning. It went in
without too much difficulty. The only change I would make to the installation instructions would be to improve removing and reinstalling the muffler rubber isolator hangers. The outside isolator is straight forward just remove isolator from muffler pin let isolator connected to the frame pin. The inside isolator pin I had to remove from the frame
pin first. I could not get it off the muffler pin until the muffler was dropped down then I could remove the isolator hanger from the muffler pin. Note, install the inside muffler isolator hanger back onto the frame pin before bolting the hitch in place. Just not enough room to get the inside isolator back on the frame pin after the hitch is installed. The spacing between the hitch cutout and the frame pin is too close to get the isolator back on the frame pin. See the two photos I have attached below.

Etrailer pulled all the stops for my order. I just finished installing the trailer connector!
My order got lost in the USPS shuffle. I contacted etrailer regarding my order and a few days later I got my part just in time for the holidays. I am very happy with the Customer service. I will definitely buy again from etrailer as I start my journey in the outdoors!
Thanks!!

Great product and fast shipping. No damage to the box and very easy instructions. I even watched the videos a few times. I had no issues except the box did not contain the hex nuts needed for the U bolt. Called customer service and it was taken care of right away. I was so excited to install, I went to local auto shop and purshcaed the correct nuts. I do wish it came with a wire brush to clean the holes the bolts went in but picked up a set. Works great and looks great on my CR-V. I would recommend and buy from again. Great job etrailer. Great product and great prices. I never have to borrow A truck again to haul.

I love my products. They still work great and look great! I use it at least 3 times a week. Holding up strong.

Thank you.

Just what I needed.
Had to chase the treads with a tap. Wire brushing just wasn't adequate. Great job on your website and the videos on the electrical hookup hardware was very helpful. I actually purchased a different one than i had in the shopping cart after watching the video.
Thanks

Timely delivery (as usual from etrailer) and simple successful installation.
My 2011 Honda CR-V didn't exactly match the video provided, but it was thorough enough that I could extrapolate ... total time *maybe* an hour -- I'm no mechanic, just reasonably handy.
Can wholeheartedly recommend etrailer and am quite happy with the wiring harness adapter for safely towing my utility trailer.

My Honda CR-V was wired for this kit to be added, and it went in perfectly. So nice to be able to add a trailer (or rent a unit) with the connection being so compatible with the factory pigtail connector.
by: Gary02/06/2022
I think the packaging needs to be better as it arrived with 2 big holes in it and I had UPS note it and I took pictures of it. I checked all parts and its fine. I Will be happy once I get it all installed so I can use my trailer.
by: David07/28/2019
The wiring harness arrived in a timely manner, fit perfectly and was easy to install due to excellent instructions and the video I watched before I even ordered it. Some folks think it's silly that the wiring runs out the CR-V rear door opening during use, but I use a trailer so infrequently (a few times a year) that it is more important to me that the wiring is out of the elements when not in use. I prefer this type of hookup because I've seen what salty winter roads do to external trailer wiring. This setup will be better for my use.
Comments
The wiring harness has fully met my expectations after a year of use. Ive only used it a few times and it has worked well each time. I still like that the wiring stays inside the vehicle when Im not pulling a trailer. The 4-pin connector still looks like new because its protected inside the vehicle.
David - 07/29/2020by: James06/18/2020
Just as simple to install as the videos show on their website. I had the interior panel open, plug was exactly where they said it would be, attached and all buttoned up in less than 15 minutes.
Comments
As good as the day I installed it. Wish everything worked this well. Would definitely purchase again.

2008 Honda CR-V
The video link was a necessary supplement to the written instructions for installing the T-One wiring harness. Step 5 should state that a confirming "click" can be heard as the connector locks into place. The white ground wire eyelet fit nicely in the existing vehicle ground terminal. However, the location of the terminal forced the mounting of the T-Connector box nearby, making the cable to the 4-Flat connector shorter than desired. A longer ground wire would help. Also, two-sided adhesive tape would have made it easier to secure the T-Connector. The instructions needs a step for securing the T-Connector.

2010 Honda CR-V
Everything worked as shown in the video. I'm not that good with working with interior panels and I did break a few of the plastic panel plugs but was able to get the trailer lights working. Best advice is to take it slow and having one of those panel screw driver type tools would have made the task a lot easier and faster.
With that said, I'm very pleased with etrailer and there products (trailer hitch and wiring harnes) - Excellence product.

2009 Honda CR-V
This hitch was a very easy install on my 2009 Honda CRV. It was shipped wicked fast and other than some paint scrapes from shipping was in perfect shape. It installs very easily. Video and written instructions are awesome. My Honda is pretty old and the weld nuts were quite rusted. Do yourself a favor and invest in a M10x1.25 thread tap to clean the weld nuts of rust. While the hitch is a cinch to install cleaning the weld nuts can be quite frustrating. The wiring harness is plug and play but again, getting the trim panels off takes some care and patience. It's all very doable for anyone with a reasonable DIY skill set. It's a very clean install at a fraction of what a dealer would charge. etrailer is a great company to do business with. The internet at its best.

CR-V 2011
This one took us a good hour to install, first timers and all.
We were too hasty screwing in the little ground screw forgetting to put the ground wire in between.... Try to remove that. It took time to undo that.
The 2 little plastic "pop screws" into the rear trim panel broke when I tried to pry them off, however they were still reusable.
I wish the tutorial video would have been a little clearer on the 'how to'. It was a bit scary to remove the trim paneling, hoping we would not break off tabs etc.
We tried the light harness and all the lights worked on the trailer.
We will not use the harness a lot, so to have it like this (hanging out the rear door when in use) is okay with us. When not in use it is stored in the spare wheel compartment.

- Troubleshooting Trailer Taillights that Don't Function Correctly When Headlights are OnIt sounds like the problem is in the ground circuit. Any time we have seen taillight circuits stop working when headlights get turned on we know the problem is the ground circuit. Since your ground wire got ripped off at one point I would make sure it is reconnected well. And you should make sure your taillight assemblies are grounded well to a clean metal surface. Some assemblies ground through the mounting hardware so you would want to make sure they are installed onto a clean metal...

I have included a picture that shows them. You may need a small flat head screwdriver to pry and release the tabs so you can unplug the old connector.

- Wiring Harness Needed for a 2008 Honda CR-VThe wiring harness for your 2008 Honda CR-V is the T-One Vehicle Wiring Harness with 4 Pole Trailer Connector, item # 118427. This harness plugs in behind the interior trim panel in the cargo area on the driver side and has a circuit protected taillight converter to combine the vehicle separate turn and brake light circuits. I have provided a link to instructions for you to review.
view full answer... - Where is the Trailer Harness Connector Located on a 2007 Honda CRV in GuatemalaIt is possible that a Honda CRV sold in Guatemala will have different wiring, but I am not familiar with vehicles sold outside of the U.S. and Canada. What I can do is tell you where the connector should be located, whether or not it is there could be dependent on where the vehicle was sold. The connector is behind the access panel on the left side of the vehicle. I have included a link to a video of an installation of this part in a 2008 CRV so you can see how he did it.

Now, with a trailer connected and the running lights on, you get a hot signal with every connection. First, you will have to disconnect the trailer to do some testing. Start by using a circuit tester to test the wires going in to the converter. Test each function separately. Turn signals, tail lights and stop lights. If these are all correct, move on to the wires coming out of the converter. Test each function again for these...

You will also need to attach the white ground wire on the wiring harness to the vehicles existing ground stud or another suitable grounding point.

The two use different installation ports on your vehicle so they would work just fine. The Tow Daddy would plug inline with your taillights and the # 118427 plugs into the taillight wiring port of your vehicle. See the install video I attached.

view full answer... - Which Trailer Wiring Kit is Best for 2007 Honda CR-VThe best trailer wiring kit we offer for your vehicle is the Tekonsha kit part # 118427 as it installs the easiest and comes with the most reliable converter box. A wire does not need to get ran to the vehicle battery either. I wish we knew what the part number of just the Honda connector you'd need is but that's not something we can get. For your 2007 Honda CR-V we do not have a 7-way wiring kit that is plug and play.

Otherwise this problem will just keep happening. First, to verify that it is a fuse, you can use the owners manual and/or the legend on the power distribution box lid to find the fuse location. Leave the harness unplugged when you change the fuse. If the running lights on the 2011 CR-V start working then we know that there was a short somewhere that caused the fuse to blow. Check...

You can access the wiring harnesses that feed the taillight assemblies by removing the interior panel on either side of the cargo area. Use a circuit tester like part # 40376 to probe the wires in the harness, as a helper puts the car in reverse with the engine off. The correct circuit should be hot, so you shouldn't have any trouble finding the correct wire. I don't have any specific information on...

You will want to check your owner's manual for the towing capacity of your CR-V. Based on my research, the 2007 CR-V has a towing capacity of 1,500 pounds. I have attached...

The trailer hitch receivers designed for your 2007 Honda CR-V are not rated with a weight distribution system, therefore you don't have the option of using one. But you can still tow a trailer.

This is part of the formula you will use to find the correct ball mount, with the other being the height from the trailer coupler to the ground - the difference will be the rise or drop you need (if the coupler is higher you need that amount of drop; if the receiver is higher you need that amount of rise).

However, I looked in the online version of your CR-V's owner's manual and it has a maximum towing capacity of 1,500 lbs so you would need to stay under that weight. If you do plan on towing, then for a trailer wiring harness you would need the T-One Vehicle Wiring Harness # 118427. I have added links to video installs on a 2011 CR-V...

The main difference between these two harnesses is that Curt uses surface-mount technology (SMT) which is newer technology from the older through-hole technology. The Curt harness also has higher amp ratings of 3 amps per circuit for the stop and turn lights and 7.5 amps per circuit for the tail lights. The Tow Ready harness...

For that you will want the # 118427 if needed. Now to convert it to a 7-way all you will need is the # 37185. This will plug right into the 4-way of your CR-V and will provide you with a 4-way and a 7-way. If you permanently mount this part it would be just like having a 7-way installed.

If you do find a camper with a GVWR of 1,500 lbs or less you could tow it but would need to start with a trailer hitch and I highly recommend the Draw-Tite Trailer Hitch # 75547 because it is a no-drill installation and the company has a strong reputation...

- Troubleshooting Trailer Left Turn Signal and Brake Lights On 2009 Honda CR-VFirst thing you should do at this point is test the 4-way of the wiring harness with a circuit tester part # PTW2993 for voltage on all of the right pins when the taillight signals are being applied. Just like in the video I attached. If the voltage checks out there but the trailer lights still don't function right then the problem is on the trailer wiring.
