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 - no cutting, splicing or tapping required. Includes tail light converter.
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 Honda CR-V'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 Honda CR-V operate.

On '93 Honda Pilot, installed wiring harness in about 20 minutes. Also installed Draw-Tite tow bar (75599) and Tow Ready 4-Flat Universal Mounting Bracket (118149) to stow wiring harness plug. None of the wiring harness is visible from rear of vehicle with only 4 - 6 inches underneath. All of the wire is tucked away in rear threshold where I found two grommets leading underneath the vehicle. After cutting out a space in the grommets for the wire harness to run I reinstalled grommets back into place. Very neat install, wire is snug behind threshold where plug was located. Worked as advertised. 122298

I had an old wood stove that needed to be transported to the metal scrap heap at the local landfill. The hitch and drawbar were already in my possession but I needed trailer wiring for a rental trailer. I looked at the trailer rental store's offering of a generic harness that involved splicing as part of the installation process; I suppose it would work just fine but this product seemed to be much easier to install. After the removal of three trunk lining fasteners I had access to the wiring plug that is standard issue for my Honda. I connected the etrailer mating half of the plug to the Honda plug, fussed with the location of the "box" and the wiring a little and I was done except for verifying with a voltmeter that all the functions were working. When not in use the bulk of the wiring is hidden in the spare tire well underneath the trunk floor panel. This harness works just fine on my 2000 Honda V6. I'm happy. 147655

UHaul had put in a trailer wiring kit years back. It failed on me. When trying to see if it could be fixed I noticed that UHaul just cut into and patched their harness directly into the wires for my tail lights. This product is designed to fit into my Acura MDX exactly how Acura intended for a trailer harness to be added to the MDX. Not to use the only crappy product UHaul had to sell and certainly not to compromise the quality of wiring to my tail lights. Do yourself a favor and buy this product. It is not very expensive. Even if it is a couple bucks more than something you would find at your local auto parts store it is far superior and it is deigned to fit your vehicle. Other kits require splicing into wires and I have no idea why you would want to do if you have the time to get one of these shipped to you. I like that this installs into the cargo area and can be stored in the cargo area. My last unit used to hang down outside of the car and was always out in the elements. I took apart my plastic cargo area and installed this while I was on the phone. After watching the installation video I did not have to even read the included directions or even think about what I was doing. It was that easy. I finished my phone call and the complete installation within 5 minutes. I also like that this has a end cap that can be covered... It should not be out in the elements when stored in the cargo area, but it is a nice touch. A very quality product. Do it yourself to avoid the crap that others will do to your vehicle with parts not designed for your vehicle. 82209

I installed the 4 pin quick connect harness and the ETBC7 universal 7 pin kit on my 2006 Honda Pilot EXL to get it ready for towing our popup camper. The instructions are clear and the installation was fairly easy but did take over 4 hours start to finish. Connected to a tekonsha voyager BC taken from our old tow vehicle. The installation looks professional, I know it was done right, and saved about $200. 210826

Was worried I would have some issues finding everything as instructions were a bit sketchy for install on Honda Element 2003. Mind you, I am not very adept around cars. Once I got everything exposed, and the plastic wall removed from the rear passenger side, it was clear this would be a cinch. The hardest part is separating the plastic wall insert from the metal body without ripping up important tabs to keep everything in place when it is time to put the wall back in place. It took about 40 minutes, only because I went slow so as not to make a mistake, not to break anything. Have yet to try it out to see if it works. 139038
by: Ryan C.07/03/2013
As expected, the installation was literally a "snap". This beat the heck of of splicing wires and drilling holes. eTrailer is my first and last stop for my trailer wiring needs! Thank you for a fantastic product! 87422
by: Martin Freibergs10/08/2014
The product was easy to find for my vehicle; installation video was right on target, and I was able to complete this project in 15 minutes. Pricing was fantastic; at the time when I had the hitch installed the installer wanted $125 to wire my Honda Pilot. This product, the etrailer video, and 15 minutes of time saved me a bundle of money. 155200

Great product! Installed on a 2003 Honda Pilot. Easy installation. Removed trim plate at rear of cargo area without any tools. There was a plug under the plate that you simply plug the wiring harness into. I leave the wiring harness in the storage area for the head rests when not in use. When I need it I pull it out connect it to my trailer and gently close the rear tailgate on the wires. 131798
by: Tim M.04/27/2013
Installation instructions were clear, and the basic installation was easy. The toughest part was getting the plug and box fit into a very tight space after it was plugged in so that the trim could fit back properly - not hugely difficult, it's just took an extra set of hands to hold back the trim and work the harness into position. We didn't use the double-stick mounting tape that was on the box. The instructions suggested leaving the wire hanging out the hatch when needed. We easily found two half-dollar sized holes - one on the inside and one on the outside - that were reasonably lined up so that we could fish the wires through to the underside of the vehicle. We simply trimmed the plastic caps that were on the holes to create a small notch around the wires and snapped them back into place after we had fished the wires through. We needed a few long zip ties to secure the wiring along the hitch bar. (One small zip tie was included with the harness.) 78135

I reviewed this product when I reviewed the trailer hitch but I will once again say the service was excellent, the harness was easy to install and was a great porduct. 92589

This harness was very easy to install and works great. It also save considerable time and effort to install. Thanks for the video, it was very helpful. Thanks, Bob F. 140032

Wow. Honda wants $280 for the hitch assembly and another $65 for the harness, plus 2 hours and $100 to install it. Ordered the kit on Thursday, had it on Monday, installed it on Tuesday in about 30 minutes. Contrary to the instructions, you don't need to drop the muffler. I'd recommend that you rest the passenger side of the hitch assembly on the tailpipe and then start the bolts on the driver's side (after taking off the tow loop, of course). Once that's done, start the bolts on the passenger side. Be prepared to use some liquid wrench on the passenger side holes because they are likely gunked up and have a touch of surface rust from 9 years of disuse. Finally, the two bolts behind the spare can be installed without removing the spare tire either. Fast, easy, cheap! I'd recommend this to anyone who's looking to put a hitch on their honda. 33765

So far so good Installed in 2005 Honda CR-V AWD. Cannot assess reliability, performance, or ease of use as yet since I have not towed with it yet. Video was helpful but left out details of how to remove two plastic rivets on cargo door threshold. Looks like the tech popped something on the rivet with a screw driver but he doesn't say how to do it... Broke one on removal. No info on best location to mount the converter box. Had to remove it twice (by ripping it off surface) to find placement without interference when re-installing trim panel. Video instructions on 12V power outlet were garbled but I pulled it out of the panel from the front side which seemed to help with removal of the panel. Unit tested fine but have not used it to tow as yet. 3345

I would recommend etrailer to my friends and family. Easy directions i have'nt wired it yet.I'm having a little trouble with the holes not lining up.Only 2 on one side and one on the other side 105632

by: David Y05/21/2009
Easy to install Installed on a 2003 Honda Odyssey van. Harness fit and functioned perfectly. The instructions say to drape the trailer plug over the trunk edge and shut the trunk on it when you use it. I found a grommet under the rear trim panel and ran it through that. The grommet was the perfect size to run the wires through and made a cleaner installation. The rear trim panel removes with only 2 screws and a bolt, so only took an extra 10 minutes. Took me about an hour total just because I spent a little more time routing wires. If I had wired it like the instructions said, it would have been a 10 minute job. 1869
Had to remove than I originally thought of the interior molding, but still very easy to install 154587

The hitch for my Honda Pilot was super easy to install. I took the tow rinf off the left frame and took a tap and cleaned the bolt holes on the right side. I took two jackstands and put them under the back of the car and slid the hitch up into place and let it rest on the stands< I placed a little lubricant in the bolt holes and the rest is history. Total time was about 40 minutes and it looks great. i also installed a T-one wire harness which actually only took about 10 minutes and it hides away nicely in the storage area. Now all I need is to go pick up my utility trailer and try it out. 39752
I was very pleased with both product and service from etrailer. The product was exactly as advertised, was shipped promptly by etrailer, and was received quickly within just a few days as promised. Installation was fairly easy. I was able to position and mount the product in a way that made it easy for future towing use. I am happy with the way it will be stowed away within the cargo bay when not in use, but will be easily accessible when needed. Now that I've installed both trailer hitch, and the wiring harness onto my '05 Honda CR-V it will make for easy towing in the future. 212978
easy install a must have if installing hitch on Honda Odyssey 126952
Installed this wiring assemble in my 2005 Honda CR-V last night and it took me ~45 minutes. The product and the etrailer video are great and that is the basis for the overall "excellent" rating. I like the easy plug-in connection and the fact that NO drilling for a ground wire was necessary. On the downside (not the product's fault, but the fault of Honda) be prepared to dismantle the interior of your CR-V as indicated by the video to access the plug in. The engineers at Honda could've done a better job at making the plug-in more accessible... 19210
by: Russ H02/28/2012
Overall good product. The video did a pretty good job explaining the installation. Watch it a few times before you start. A couple of hints...first, taking the side panel off is easier if you unscrew a fastener at the front of the panel, just behind the rear seat. You'll see it when you get the carpet out. Second, the adhesive that is supposed to hold the box to the side of the panel is not strong enough to hold it on. I was afraid that it would come loose and rattle, so I drilled a small hole and screwed it to the inside of the panel. 32736

by: Scott G.07/08/2012
Fit perfect. The instructions could have been better -- they should have stated that you install the wiring by first removing the fitted rear well enclosure and accessory container. You will see that Honda already has wiring going through this section to the speaker assembly. Simply install your new wiring the same way. These instructions prevent a complete novice -- such as my self -- from thinking that after connecting the wire to the wire harness that the wire should go out the speaker opening into the cabin -- which is wrong! 47121
Ordering/shipment was great! Install went fine. Instructions were adequate. My install was on a 2006 CRV, for all the years listed they didn't seem to include specifics on how to route the wiring to the outside of the car? I got to the connector in the car fine, but running the wire to the hitch was more troublesome. finding a place to get the wiring to the outside with drilling was very cumbersome. I eventually did find something after alot of pulling, reaching, probing, bumps, bruises, and cuts to the fingers and hands. 14131
by: Russ H12/25/2014
Directions were great for how to access the factory installed plug (Honda CRV) Only thing stopping me from giving it 5 Star's was the lack of details or suggestions as to the best way to get the 4 wire plug assembly from inside the vehicle to the hitch area outside the vehicle. I removed one of the Honda factory installed grommets in the cargo storage area, widened the hole , routed the plug through it modified the grommet a bit, then some clear silicone to seal it all up!! All in all good product easy installation. 166905

2004 Honda Odessey Trailer Hitch, Arrived quickly after being ordered and shipped just prior to Memorial Day Weekend, about 6 days. Hitch and brake light assembly were very easy to install. Hitch installed in less than 30 minutes and was able to slide in into place without lowering exhaus (Six 3/4-inch bolts installed in OEM hitch plugs in the frame. Wiring assembly took about 5 minutes (one trim screw) and plug into OEM trailer light socket that T's off of brake light assembly. 82558

I am of the generation that believes your word is your bond. In today's world it is hard to find a business that will do what it claims. Etrailer is one of the exceptions. Not only did they provide a quality product (hitch and wiring harness), they provided it in a quicker time frame than I expected, made installation instructions and on-line videos clear and precise, and most of all kept me abreast of order status. Etrailer not only says what it will do, it does what it says. 24581

I received my order yesterday, a day ahead of schedule which was very convenient and all the correct items we included and carefully packaged. I turned over the installation over to my nephew which using every day tools had the hitch and wiring harness installed and working within 45 min. Impressive I must say. After he was done I could hardly see the receiver, normally the ones I see are huge, clunky and look to industrial for a small SUV like mine. It's a clean look. 104000

I'm someone who isn't shy of working on a car, but I don't do it often and I need clear directions. In the case of the trailer connector, the online videos were of critical help, as the written instructions weren't all that detailed. It took about 1 hour to installed (and that's because I took my time), and all seems to be working correctly. I'm very happy with e-trailer, and I would recommend it to all my friends who need to make trailer-related purchases. 18041
by: Scott Bond01/12/2013
Not much to it. The directions were short but adequate. I just located the plug in my vehicle per the directions, plugged in the harness and voila, I had trailer wiring! Its simple and it works and its inexpensive. Just what I needed. I will probably only use it a few times a year, so I can't speak for its longevity at this point. E-trailer expedited the shipping for me. This is my second order from them have nothing but praise for how they do business. 62807

This had to be the best wiring harness I have ever purchased. Easy to install, great instructions with video, great quality, and the price was perfect. The support group kept me informed on when my purchase was shipped and when it was delivered. The product worked without any issues at all. What more can you ask? I am a etrailer customer for good and I am definately recommending them to my friends and family. Keep up the good work etrailer, I'm impressed.... 83771
2008 Honda Pilot Quality was good. The video for the older version of the Pilot are not accurate for the 2008 model. The plug is int he same location but when you remove the trim, the clip is not fully accessible. I was able to squeeze my hands in and clip it together then pull it up into the storage area. There are some plastic knock-outs that you could push the harness through to the underneath but it would be hard because your hands can't get in there. 3991
by: Andrew P.09/10/2013
Product seemed very well made. The wiring seemed thicker then the factory harness I got from Honda so I assume it will last longer. The ordering process went very smoothly and everything was shipped correctly and quickly. The shipping costs were also surprisingly low whereas other websites were marketing this product for similar prices but the shipping costs were ridiculous. Anyway, great product and service. I will be a repeat customer when the time comes. 99247

I was preparing to move out-of-state and needed to rent a trailer. I didn't want to pay what the rental facility was asking to install the trailer wiring harness on my vehicle so thanks to a YouTube video my brother sent me, I ordered everything I needed from eTrailer. As someone who knows NOTHING about automotive repair and isn't tool savvy, I was amazed at how easy it was to install. The YouTube video was specific for my year/make/model and was spot on. 196765
by: Austin S.07/04/2013
The harness worked perfectly and plugged right into our Honda CRV without splicing any wires. Thanks to ETrailers Youtube video I was able to convidently install within about 10 minutes without breaking anything. Shipping was very fast and I am glad that ETrailer tends to use UPS as they alway deliver right to my door as opposed to the USPS that often leaves a note in my mailbox to pickup at the post office. Thanks again ETRAILER. Austin 87732
by: Jeff Vandenberg08/22/2013
This product was just as advertised! The video make installation incredibly easy. In fact, the ONLY way installation would have been any easier was if the trailer harness had already been installed. The step-by-step instructions in the video were spot on and I had easily completed installation in under ten minutes. I am amazed that my local U-Haul center wanted over $60 to install a trailer harness. Delivery was just as noted to. FAST! 96349
excellent product. As described and easy to install. The only thing I would change would be to say that they did not have a link to a good video explaining where the trailer light assembly is attached to on my particular vehicle, however, a quick search on Google yielded a video that happened to be from etrailer.com concerning my vehicle. Fix that link and I don't think anyone would expect anything more from a company. Good job! 147398
by: Dave C.04/23/2009
Great Product - Great Price - Easy install.. A wiring harness for the Honda Pilot is $65 at Honda parts... plus it is designed to hang outside the vehicle. I watched the install video twice online. When the harness arrived, I didn't even look at the instructions. I went straight to the vehicle, popped open the panels, plugged it in and had it done in three minutes. The hardest part was getting the tape off the plug in the vehicle. 1783
Once again Etrailer was amazing. This was my second order and I had to order over the phone since my internet connection wasn't great. The customer service was amazing I was helped quickly and very efficiently. My order came just as estimated. The videos of ETrailer make it really simple to order the correct part along with the customer service which will also check to make sure the correct part is compatible. Thank you so much. 199024
by: Larry M.07/04/2013
Very quick delivery and the products (Draw-Tite Hitch, adapters, and Wiring Harness) were just as described. Installation was reasonably quick and easy. The installation videos were great. I took my time and was able to do the entire install in a bit under 3 hours by myself. The hardest part was disconnecting the plastic molding connectors to expose my Honda CRV's trailer plug. Very pleased with eTrailer and will use them again. 87700
Great product and super easy install. I couldn't believe how fast the product arrived. Ordered on Sunday night and delivered Tuesday afternoon with standard delivery. I also received e-mails that let me know the item was in stock, when it was being shipped, and the expected delivery date. The videos that were on the site were very helpful and made install incredibly easy. I kid you not, total time for install was 5 minutes. 43947
by: Henry C.03/20/2012
Ordered multiple items from etrailer.com multiple times, delivery of the products were all fast. Instruction videos on the installation of this trailer wire harness helped me breeze thru the actual installation. Also purchased the trailer hitch and bike rack for a complete set of gears. Etrailer.com had installation videos for these items also. Would definitely refer friends to shop here for trailer related stuff. 34540
Purchased the 2" receiver, wiring harness & hitch pin. After reading the reviews, I went ahead with the order and found it to be as easy or easier than possible. Free shipping came right to the door and I had it in place within 15 minutes. What made this all possible was the added online videos that show anyone can install these hitches and I went from farming out the job to do it yourself. Thank you Etrailer! 168619
by: Jason K.08/17/2015
I have a 2006 Pilot. I got this harness just in case I ever need to tow a light trailer, so I haven't actually used it yet. However it is hooked up and ready when needed. It seems to be of good quality. It was easy to install and was plenty long enough. Watching the Youtube video on installation made everything easier. There was even a link in the video to click to order. Great product at a great price. 219833
