T-One Vehicle Wiring Harness with 4-Pole Flat Trailer Connector
Quickly and easily install a 4-way trailer connector on your Honda CR-V with this custom wiring harness. T-One connector plugs directly into existing wiring. Powered ModuLite reduces strain on wiring system.
This custom-fit T-One connector plugs into your Honda CR-V's wiring harness, which is located in your rear cargo area, behind the driver's-side and passenger's-side interior trim panels.
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 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 Honda CR-V'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 Honda CR-V operate.
With a ModuLite, your trailer's lights will be powered without overloading your Honda CR-V'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.

Today we're going to review part number 118561. This is the Tow Ready T1 Vehicle Wiring Harness with the 4 way flat trailer connector. This is a custom fit part number. It is designed to fit the Honda CRV starting in 2012. I would recommend on a custom fit part, is go to our website. Use our fit guide, putting your year and model vehicle and it will show you if this part will work for your application. Now, this will provide this 4 way flat trailer connector, the back of your vehicle to power your trailer signal lights.
This does connect quickly, easily. There's no cutting or splicing of wires. Basically, you'll just locate the connection points usually behind the driver's side taillights, plug in this T connector right here, plug in your module to your wiring harness, put in your fuse and you should be ready to go. Now, it does include the circuit protected taillight converter and this is to ensure that your vehicle's wire will match that of your trailer and it does provide protection against electrical shorts and overloads. On the 4 way, you can see they give you a length of wire. It is a 16 gauge bonded wire and on the very end, it has the dust cap. Basically when you're not using your 4 way, you can just put your dust cap over it to protect it from getting damaged or from the elements getting to it. Specs on this wiring harness, the maximum amperage for the stop and turn light circuit is 2.1 amps per circuit.
On the taillight circuit it's 5 amps per circuit. It does give you a nice set of instructions, shows you exactly where your finishing points are, how to install it. Basically what you would do is go to the back of the vehicle and then you have this T connector right here, you'll locate the connector on the driver side behind the upper trim panel. They'll have connectors that will match these right here, plug this in and then what you want to do is go to this portion right here where there's the gray plug in and that's where your converter will plug into, so you just plug that in like that. Then it has a piece of double faced tape on it. You want to mount this black module in the interior of the vehicle.
You don't want to have it on the outside. Then you have a white wire coming off with an eyelet on it. That's a ground wire. You want to connect this to a good clean ground. If there's one screw to mount it to, go ahead and do that. If not, they include a grounding screw where you can drill a hole and make your own clean ground.
It does also come with this 5 amp fuse that's already installed, an inline fuse holder. You'll run this 4 way cord out towards the back of the vehicle. The last thing you want to do, now it does give you some cable ties here to take up any slack in the wiring and the last thing you want to do is include this little mini 7.5 amp fuse and you'll go to the fuse box, which is located under the driver's side dash and you'll find the location to install this 7.5 amp fuse in it. Once that's all done, your wiring harness should be all ready to go, ready to connect to your trailer. That should do it for the review of part number 118561. This is the Tow Ready T1 Vehicle Wiring Harness with the 4 way flat trailer connector. .
Average Customer Rating: 4.9 out of 5 stars (97 Customer Reviews)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. Powered ModuLite reduces strain on wiring system.

I ordered a hitch and the wiring harness on a Monday afternoon. The U.P.S. man delivered two days later on Wednesday at 3-30pm and I had both items installed by 6-30pm. Quality of both items is first class. Customer service offered by e trailer was just exceptional. Overall a great purchasing experience. The videos provided for installation are a great help. I watched them a couple of times before I even ordered the products and they certainly help fill in the blanks left in the written instructions. The comments written by other customers were also invaluable. I too left the rear panel in place on my CRV and cut the opening leaving a "hinge" at the rear of the car. Just pull it down, slip the hitch into place and replace flap. I am in my mid seventies so used a floor jack to support the hitch when installing bolts. No problem installing both items on my own. One minor issue,,,,,,the name plate on the hitch is not installed level!! Other than that small issue, I would highly recommend both products. The product supplier is to be highly commended for the way in which it deals with customers, just superb.. 89150
I haven't installed the trailer hitch and wiring harness yet, but they arrived promptly and in good shape. I will definitely go to etrailer.com for my future purchases of products they carry. 63165

I purchased the T-one Vehicle Wiring Harness from Etrailer about a week ago. Shipping was extremely fast, it arrived on the 3rd day after purchase. Installation was an absolute snap, anyone can do it and you do not need any special tools; took me about 30 minutes total. Watch the video. I left the video on play during installation which helped a lot. This is a modular plug-in and use wiring harness, no need to cut, splice, tape, etc. A high quality product you will not be disappointed with. Great price from Etrailer, too ! 142458
by: Mark A.08/10/2013
Very easy installation. Followed the video. Harness worked perfectly. I would recommend an interior panel tool. The hardest part of the job is reaasembling everything. It went fairly easily. I found that there is an order in the way you replace everything. Unfortunately, I learned it by trial and error. I would say it took about 45 minutes to an hour to complete the job. 94364

Wow! What an excellent product. No splicing of wires- just plug and play. Kit included everything, even the proper fuse to use in my vehicle's fuse block. Written instructions were very good, but I also used Etrailer's website installation video which made it a no brainer- most excellent! As a side note: hats off to Honda for having the 12 volt source pre-wired all the way to the fuse block. All I had to do was plug this unit in line behind the left rear tail light, pop the fuse in, dress up the wired and DONE! It can't be any better than this. 232090

Rather easy to install, however, the plastic push clips must be carefully dealt with, or else you break them, or forget where they go, because they fall out. Otherwise, it worked. 105942
This is a good product as long as you can do this type of thing on your own. There were no problems with installing the harness and it worked the first time. However, if you've worked on automobile interior panels, you know that taking them apart is easier than putting them back so they align, etc. I ended up with an 1/8" gap I'll just live with. The biggest issue was the handle that releases the rear seat. It's a separate unit that snaps into the rear of the side-panel. It kept dislodging when I re-installed the panel and tightened the two screws. This cause the handle to strike the side of the panel when I pulled the handle to test it. The solution - for me - was to insert two washers behind each screw so the handle unit wouldn't tighten down as much. I secured the washers in place with plumber's putty, then installed the side panel on top, inserted the screws and tightened them only slightly. It will take longer to reassemble the panels than to diassemble them. A few video tips would be helpful. Regardless, this is better than paying Honda $178.00. 108026
I installed the DrawTite hitch in about 45 minutes without any problems. The next day I did the wiring and it was very easy. Once the panels in my 2013 Honda CRV were pulled open, the wiring harness just plugs right in and then the panels are snapped back into place. The wiring took about 35 minutes. Easy installation on the hitch and the wiring. Thanks so much. 73241

I recently purchased a trailer hitch and wiring harness for my new 2016 CRV. It arrived quickly and in good shape. After watching the installation videos several times, the installation was quits simple and straight forward. For the cutout in the appearance panel, I made a template to trace using the measurements given in the instructions and cut it out without removing the panel from the car. When the hitch was completely bolted in place, I drilled matching holes (about 3 per side) in the cutout piece and the panel still in place and "laced" them together using small cable ties to cover the opening and then sprayed the spot with Flex Seal to complete the job. Installing the wiring harness was just as shown in the videos. What a difference from the days of identifying wires and splicing them together! 321221

I purchased the T-One Vehicle Wiring Harness #118561 for my 2012 Honda CR-V. The wiring harness install was very simple, simply plug in the connections. The difficult part was removing and then reinstalling the interior panels in the vehicle. I highly recommend viewing the install video, which was very helpful. The video recommends running the four wire plug into the spare tire well, for storage. Then you have to access the four wire connector every time you want to tow. I ran the four wire connector down thru a rubber grommet behind the trim panel, prior to closing things up. I was able to thread the end of the four wire down thru the flap I made in the underside panel, along the back side of the trailer hitch and secure it with zip ties. My total install time was about an hour. 111416

This is great designing product. It took me 30 minutes to get thing done with the detailed video demo. It's kind of pleasure thing to install myself with the instruction video. 88128
I received the hitch Friday evening and it was mounted on my CRV Saturday afternoon. The instructions for the electrical installation were the most complicated and spot on. The hidden snaps and fasteners on car trim parts aren't easy to find and the instructional video was great. Everything came off and back on with no damage. The hitch is rated a 4 in difficulty out of 10. It was more for me at 74 years old and 98 degree Florida heat bit it went on as described. I would recommend etrailer developing a template pattern for cutting the hole in the plastic underbody cover part of the rear. Showing an installation that just removes and leaves it off is lame, Honda put this on for a reason. Cutting the opening and getting the cover back on was not fun. 257501
by: Rick M.09/23/2013
This receiver hitch is outstanding! I watched the video online and then used the instructions to complete the installation. Since this was my 2nd installation I took my time. No problems...I also installed the wiring kit and everything went smooth, the hitch and wiring both work great! Thank you for providing a superior product at a fair price.. rm 101167
by: Marc K07/22/2014
Awesome product and awesome instructions. The video was perfect!! Watched the video, paused it after each step then did it on my car. Went perfectly! I did buy a cheap set of tools on Amazon to help with the plastic rivets and trim panels, but they were only like 10 bucks and worth every penny I think. Honda dealer wanted $950 to install a hitch and wiring. I didn't feel comfortable installing a tow hitch on my car so I had that done at a local car shop for $250. Spent another $75 or so on the wiring harness and tools, so I'm in for $325 instead of paying the dealer's price. Next time I need a wiring harness or anything for my trailer I will DEFINITELY use etrailer.com!!!!! 142533
Already on the car and works great. It took about 90minutes from start to finish. That included putting everything back together and testing. If I did another one it would only take half th time noe that I know what to expect. All of the other ones involved running a wire under the vehicle to the battery. This item is all within the rear of the vehicle. Only one hole to drill for the ground wire, and that stays inside the car also. The only problem I encountered was getting the panels off of the interior (bigger pictures would help) . I would highly recommend this item. It is easily installed by most anyone with a minimum amount of mechanical or electrical skill. 56532
Hitch came in quickly and I installed it right away. Because this is a BRAND NEW car I was pretty anxious about removing the panels and getting into the electrical system as well as doing the cutout that is required. The videos are VERY helpful and while it took longer than suggested because I took my time, it was in the end pretty straight forward. I may have set the electrical plug too far off center. If you are not careful, the trailer wire can be set up too short to handle a right turn or too long and drag on the ground. It would not be too difficult to move if I needed to.It would be better to have a connector bracket the fit the tube on the hitch directly. 65478

The T-One Vehicle Wiring Harness is purchased from e-trailer came packaged well and in good condition. The harness easily attached, per the instructions, to the exiting 2105 Honda CRV wiring plug. The wiring harness has worked very well so far. However, removing all the CRV paneling to get to the Honda plug to connect the harness was a challenge (Honda didn't want to make this easy so you would buy a Honda's wiring kit.) I also found a hole in the spare tire well to thread the wiring harness to my hitch so it would be mounted permanently (avoiding just leaving the harness wiring loose in the tire well). 321119
by: Dennis J.04/10/2013
A great product that just plugs right in. Removing the interior panels is kind of scary if you haven't done it before. Really easy to install the wiring harness, just be sure to double check where you have placed the wiring around the control module as the screws in the panel that secure the back seat release lever are located very close to where you might place the wires and the panel doesn't afford much clearance space in this area. I tucked most of the wires up under the highest most trim panel and routed it more towards the rear of the car before bringing it down. 75295
by: Tom D.08/03/2016
Wiring has worked fine. I just wish it was more permanently run outside the CR-V. Instead, you have to open the back, move all your stuff out, lift up our weathertech floor liner, and lift up the spare tire cover to get the wiring out. Then you string it out the rear hatch door and close the door on the wiring. On the plus side, when not in use, the wiring is perfectly protected for the elements. On the downside, clearing out the back to get the wiring stinks, and I'm concerned about the wires kinking over the long term from being close in the door repeatedly. 278904

Again the video and instructions were spot on. The biggest problem with the install had to do with the car not the kit. Breaking loose the trim panels was not real easy, and re-installing afterwards was more difficult because they had to be pushed away to access the blue plug. I chose not to dangle the four pole plug out of the tailgate but rather I drilled a hole in the rear spare tire well, cut the wires and re-connected them inside the well. Everything went well and it looks better than a wire harness sticking out of the tailgate. 165753
by: Gary L09/11/2016
My package arrived quickly and was easy to install, it took about an hour. The trickiest part is measuring to cut out the hole. I would recommend following the directions provided the best you can for the measurements. I watched the video for the rest of the install. My hole appeared to be in a slightly different location than the video. I had no other problems with exhaust, etc. but the car is brand new. The T-One wiring harness (118561) was easy to install too, I just followed along with the video step by step. 293540
I've used similar harnesses before, but this was the easiest. Only had to access drivers side tail light, not both. The video shows more removal of panels than I found necessary. Once I had the rear portion of lower and upper panel loose I could see the connector I needed to unplug, so just reached my hand in and up and unplugged it. Saved removing the other two panels they recommend removing. And these plug-in harnesses are far superior to any 'cut into the wiring' methods I had to use in the 'old days'! 253546

E trailer only handles top quality merchandise and this vehicle wiring harness looks like another example. I haven't installed yet, but will use their installation video when I do. I like to deal with E trailer as my hearing is so bad and they have an excellent website to find the products you need. I have had to have help before and once informed my hearing was impaired, they made a strong effort to speak so I could hear. The reviews are very helpful in deciding on which product to purchase. 163093

I ordered this harness and a Curt hitch for my 2012 Honda CR-V. I have not used the harness yet but the hitch installation went without a "hitch". Took only a hour. Most of that time I spent searching for tools. It looks great and I expect it will perform as intended for many years. Etrailer customer service and delivery are top notch. They matched Amazon price plus 10% as promised. They even upgraded shipping at no extra cost to me. It has been my pleasure doing business with them. 55733
Wonderful plug and play install. I did take advantage of a panel tool and someone familiar with how these panels attach and how to remove. He was not as gentle as I would have been ( he had done this before) and he did talk trash to them a few times. In the end the panel removal was straightforward and the wiring harness was truly plug and play. We were done in just over half hour. Very nicely engineered product and sure beats running wires to the fuse box and splicing. 182894
by: Doug O09/23/2016
Everything I ordered to install the hitch on my CR-V installed as described. Honda didn't make the installation simple but the instructions overcame this and I got everything installed in a couple of hours; saving myself $600.00 from the factory installation. Ordered from etrailer previously and liked the quality of the products they sell and the hitch came well crated with a minimum of dings to the paint which was easy enough to touch up. 298267
This is my second installation of one of these harnesses. I brought my CRV home from the dealer yesterday and had this done in less than an hour. The toughest part was realigning the interior panels. A plug and play system; no fishing leads to the battery, no bare wires, no soldering, no taping. This has become my number one installation on any vehicle I purchase. With Etrailers fast shipping, you get what you want when you want it. 126882

Ordered 4/13, arrived on 5/20. Delayed as part of a shipment; another product in the same shipment was on back order. Went together as advertised. The movie provided for installation was spot on, except that my 2013 Honda CRV had no accessible screw/bolt as shown in the movie to attach the ground wire. I drilled a 3/32 inch hole for the screw provided in the kit, as shown in the kit's printed directions. No surprises, otherwise. 81440
This product is as advertised-installed on a 2012 Honda CRV. I would however, have the u tube video handy as the printed instructions leave you wondering in spots. The video is spot on and leads you step by step through the install. Pay attention to how the plastic pieces of the car relate to one another and how they come apart; this will aid in their re-assembly. Part worked flawlessly-truely "plug and play." 73441
The printed instructions for this need to be better with more illustrations. The on line video is great and after watching it a second time discovered what I was missing and then had no more trouble connecting the harness. Did have to try several times before I got the inside body moldings back in tight but that's because I pulled them out too far. Product worked fine after installation. 263605
by: Edward R.10/22/2016
Installation directions were good but need to read over them first. I am not a master assembler so I needed to go slow. Don't force anything when taking the interior panels off or putting them back on after the wiring installation. I did damage the 'button' that holds one of the side panels and need to get another. No big deal but inconvenient. Worked first time and have had no problems. 309621
by: Rich F11/25/2013
I have not installed my hitch and harness yet, as I travel a lot on business. But I will say, I received the hitch and harness very quickly and did a quick inspection of the contents. All looks good and I will send in more comments and a photo or two after the install. This is the second hitch I have ordered from you guys and if this goes like the first one did...it was PERFECT!! Thx! 108500
by: Andi D10/17/2014
Clear instructions and easy to install We watched installation video and that helped as well. Used the free shipping and I received the hitch and lighting kit in 2 days! Amazing! 156591
by: Jason Dahly09/03/2014
I recieved the wiring harness in 2 days from the time I ordered it. Watched video on how to install wiring harness on 2014 CRV and everything went great. Took me about 45min to install wiring harness. Saved over $250.00 by installing hitch and wiring harness myself. I would recomend any one to watch video and install items yourself. Looks great and works great. 150013
by: Larry H08/25/2014
Great product and service from etrailer. Delivered quickly. Plug and play. BUT - working with those interior panels is tuff! Instructions and video were very good. Getting the bottom panel re-aligned after installing the harness took me some time (I am a novice) but finally got everything back correctly. Note - Honda CRV 2014. 148348
by: Stephen D.08/04/2014
I just installed this product on a 2014 Honda CRV. This product is genius! I love the fact that I did not have to run a separate line to the battery. The hardest part of the install would have been figuring out how to remove the trim panels, but after watching the video I knew just what to do. etrailer rocks!!! 144223
by: Gary N.11/20/2014
The wiring harness was what I was looking for, or some thing like it from my Honda dealer, but the only thing the had was a hookup that needed to be mounted outside of the auto. You harness was 1/3 the price as theirs, and was easier to install. Thanks to your sales staff for their knowledge of your products. 161976
The wiring installation was super easy. No pictures needed because the YouTube video couldn't have more spot on. Coming from someone who is not very mechanically inclined and was able to do this...a trained monkey could follow these instructions...that easy! Took 25 minutes. 314036
by: Dave R09/23/2012
2012 Honda Civic - Hitch was here 2 days after order placed. My son had it put on in about 1 hour. You do have to cut a hole in the plastic bed pan on the drivers side but it is WAY out of view. The plug and play wire harness took about 45 minutes and works great. Good product. 55541
by: Mike D.09/07/2016
This wiring harness is performing flawlessly. Installation was much easier thanks to the great pics and videos. The wiring is sufficiently long enough and protected by the flexible split cable shield. I installed this in a 2015 CRV EX. Very happy with this product! 292071
by: Scott F.05/13/2014
I installed a Curt Trailer Hitch and T-One Wiring Harness on my 2014 Honda CR-V last night. I had never installed a hitch before. I just followed your instructional videos and went to work. Saved myself $250 and the install went perfect. Thanks ETrailer! 130362
Delivery was prompt and hitch was in perfect condition. Instructional video was very helpful as were comments/suggestions from other customers. Installation time estimate was almost to the minute for the time it took me to install alone. Very satisfied ! 65381
by: Walt B.07/11/2013
The trailer hitch and lighting kit arrived on time. The instructions were flawless and the install was easy. This is my third purchase from etrailer.com and their service, products and instructions have always been top notch. They are the best! 88990
Good product but installation more difficult than video shows. Plastic panels have sharp edges and it takes an extra pair of hands to hold panels back so that wiring can be connected. Some panels harder to put back in place than video shows. 301554
Perfect product. Everything worked as it was suppose to. I installed this on my 2012 CRV, plug and play. The video instruction were amazing. Everything should have video instructions that good. The whole thing took less than 30 minutes. 100541
Video was really helpful for installing this piece, because of the wiring connections being behind the trim panels. Given the video, installation was straightforward, and it plugged in and worked just as it should. We've got lights! 200721
Great product came to house in 3 days installed in under one hour. Did not take under cover off, I cut it on the car with a utility knife and cut only three sides to make a flap then trimmed flap with my knife to fit. 59240
by: Robert M06/11/2016
Product arrived within 5 days of ordering, which was done on a weekend. Excellent instructions for install. Too bad my trusted mechanic didn't take the time to view the video. But it's installed and looks good. 260156
by: Tom N.09/15/2016
Hitch installed without difficulty. Very straight forward and fit exactly like advertised. Wiring instructions needed more illustrating and photos to be less difficult to understand what was necessary to connect. 295001
Fast shipping as always. I put it on this morning, very easy job. Have not installed the harness but have read the instructions and dont see a problem. Thanks, Scott 70289
