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.

This will be a rather long review since I am combining the entire purchase in this one review. To start I am a 60+ yr. old female & not mechanically inclined but after getting an estimate of over $900. 00 from the local Honda dealer to install a receiver & the electrical wiring so that I could tow a small trailer I decided to shop around. I wasn't even sure of what all I would need or what the parts were called except for the ball. I visited a few websites & sent a few emails to inquire. Etrailer was the first to respond to my questions & provided links so I went back to their site. After viewing a video on the different receivers that would fit my Honda Pilot I favored the Curt receiver. That was my starting point & I moved on to the next item I would need which was the hitch. I never knew there were so many possibilities & I didn't have a clue what the rise & drop was all about so I sent another email. Within a matter of hours I'd gotten a response from a fellow named Jon G. He was just the hook-up I needed!! The links he provided answered all of questions I had & gave me the education I needed. (I was still waiting for responses from the other websites I'd sent inquiries to.) I was certain at this point that I would make my purchase with & proceeded filling up my shopping cart with the Curt receiver, the Curt ball mount, the chrome hitch ball, the electrical wiring & an anti-rattle hitch pin. Before I paid for the items I asked Jon G. for 1 more favor. Would he kindly view the items in my cart to make sure I had matched the items up so that each would fit correctly with the other. He did & I made the purchase. Within a few days the order arrived & I was confident enough after watching the installation video & reading other reviews that I could install everything myself. I used the lift in a friend's garage & enlisted the help of a female friend. She held the receiver up on one end while I was at the other installing the bolts. Then it was her turn. Together we had the receiver installed in less than 30 minutes. It was so easy!! Next, we installed the wiring That took close to an hour. Mainly because we were trying to be so careful when pulling back the rubber & popping out the panel clips but we got 'er done & did a beautiful job of it, if I may say so myself. All in all, it took almost 2 hours to complete but that includes disposing of cardboard boxes, putting away the tools, lowering the S-L-O-W lift & backing the vehicle out of the garage. etrailer is #1 in Customer Service & Satisfaction, Product Variety & Quality & Anything that You want to Hitch. Well, almost can't hitch your kid....or, your, dogs. Thanks again, etrailer. You guys are BOSS!!! 331149

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


No problems at all one year after the install.

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

Fastest delivery I have ever had. Ordered Wednesday at 5PM, arrived Thursday at 3PM. I'm only a couple hundred miles from Wentzville, but still, excellent. The hitch receiver (2008 Pilot) installed quickly and easily. No need to remove spare or lower muffler. I supported the left end on a large cooler and quickly maneuvered the right side above the tail pipes. The mounting holes were right on target. I had to tap mine to remove rust, but that's easy as well. The wiring harness was also a snapto install. Simple to plug into existing fitting and the wiring box tucked away nicely beneath the trim as advertised. There are options about what to do with the wiring tail and trailer connector. I chose the method shown in the video...leave it rubber-banded in the storage well. Others have run it outside through available holes, but I did not want to leave it exposed to road grime. etrailer's videos were very detailed and shown on my specific vehicle for both the hitch and the wiring harness. Good values as well. If I were Draw-Tite (or Curt) I would include a complementary rubber plug with their advertising. 430540

This hitch was exactly as advertised and fit my CRV perfectly!!! Used spray bottle with soap & water to lube the two upper muffler rear hangers and they slid off with little prying needed (did not need to remove the lower hanger in front of muffler). etrailer's installation videos for installing both this hitch and corresponding 118336 wiring harness were spot-on and very helpful (also a good video on the Curt website). Took my time tightening the hitch bolts to specs which was a bit awkward until I thought to use my ratchet extension bars. Maybe the easiest "car repair" I've ever done, and probably saved a lot of $$$ doing it myself. If you can change your oil, you can do this installation no problem! Also, etrailer promptly shipped this product for free (thanks, guys!) and it got here a day early. GREAT COMPANY! When I save up enough to buy roof rack rails in the near future, I'll be back... 401319

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


Do you have to take the complete side panel off?

-- comment by: Jim M - 07/17/2014


Almost had to remove entire side panel - did not remove the most forward secured part. Was able to torque out bottom and back end of side panel enough for my wife to connect the wire to the Elements connection wire once she cut the tape which secured several wire connections. She was then able to put all back behind the panel - her hands are smaller than mine, so it worked out OK. Needed 2 hands to do it this way.

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


Ive used this harness several times over the course of the year. It is durable and works perfectly! I will definitely be using eTrailer going forward. I have referred them to several of my friends! I take reviews very seriously and wanted to make sure I plugged these guys because they are great at what they do! Thanks again eTrailer!

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


Its working great. No problems and still love it.

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


Thanks for the follow up - One year later the products are working spectacular and I keep plugging away at your company - telling all of my friends about it.

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


Yes I am still completely satisfied with both the hitch and wiring harness.

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


Could not be happier with the products, the perfect fit, the fast deliver and the ease of installation I installed them myself as well as one for my Tacoma truck that I bought about 2 years ago However, I do recommend a second person to help as you state in your directions

Had weird acting trailer lights for quite awhile. When I checked voltages at the vehicle I noticed low voltages for one of the TS. I suspected the 4 way adapter that was installed in 1999 Odyssey. I purchased this one from eTrailer, hooked it into the van and it fixed the issues. The trailer lights are now rock solid. I guess the TS converter on the old one had an issue. All is well now. 217772

The wiring harness works great. My brother in law has the same car as I do and he paid over $100 to get his trailer wiring harness installed. He nearly died when told him was mine cost ms how easy it was to install!

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

This item is actually the 2nd harness Ive ordered from e-trailer. I bought one years ago for my 2000 Honda Passport. The most recent harness was purchased for my buddys Honda CRV. Both continue to work flawlessly.

Purchased the Curt trailer hitch receiver, wiring harness, & ball mount for my 2004 Honda CR-V. Delivery was free and the items arrived within several days after I ordered. It took me about a hour by myself several weeks ago to install the wiring harness with all the parts that had to be removed & replaced to do it. It was a simple task thanks to the installation video on eTrailer's web site. I waited until my grandson was home from college to install the hitch receiver. Today it took the two of us less than a hour to mount it. Thanks again to eTrailer for the installation video provided to show step by step installation. The ball mount appears to be a good quality sturdy product. The purchase price was quite reasonable and I will shop at again. 250719

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

Great products and prices, fast shipping. I opened the box right up to give me a surface to lie on and slide under the car. Instructions were good and the installation times for pro and novice were useful. The installation videos for the hitch and car wiring were helpful. The fishwires are brilliant for placing the bolts, but you should know the diagram is wrong. As depicted, the path of the wire thru the spacers would require the bolt and spacer to flip over inside the frame for the bolt to emerge thru the hole. I also found the follow-up information "trailer wiring 101" and similar articles useful. etrailer is doing a good job of being the one-stop place for products and advice. 377240

I was not as enamored with this wiring harness as I was with the hitch. Instructions left a lot to be desired. The wire from the converter could have been a foot longer and that would have been very nice to finish the job. No discussion as to how to run the wire from the side panel to the hitch. Videos go only to show plugging it in to existing wiring and then say not much more. A couple of other videos I looked at just show the connector end just laying in the back of the vehicle. No nearly enough wire for that to work. I made it work be not real pleased with installation documentation. One good video from start to finish is needed. 206139

This was pretty easy to install and works great on my trailer. The installation instructions were not exactly correct for my 2004 Honda Element AWD Ex. The number of screws and plastic plugs that needed to be removed to pull the passenger side trim panel clear to access the vehicle's connector did not match the instructions. I found it essential to unbolt the right rear shoulder strap from the floor of the vehicle. This allowed much better access to the wiring behind the panel to plug in the connector for the harness. The adhesive on the black box that comes with the harness was weak, and didn't stick to anything behind the panel. 354989

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

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

I wrote about the wiring harness in my review of the hitch installation. Many talked about how difficult it was. I followed the directions for my Honda Pilot and found it very quick and easy. It stows in the compartment with the head rests and I pull it out when I need to hook it up. Pretty simple. If only it could be accessible right at the receiver without hanging out the rear hatch it would look a lot better. Picky, picky, picky. But, that's why I gave it a 4 out of 5. The etrailer staff were extremely helpful and quick to respond with precise info. Thanks folks. 313231

Fast shipping (Ordered Tuesday night, received today Friday). Very pleased with the quality. Installation was quick, except for the bolts on the right. Because there were never bolts in the holes (no hitch was ever installed on our Honda Pilot), the holes were rusted and it was difficult to install them. Otherwise, the installation would have taken a mere 45 minutes. Have yet to test out the brake lights (I ordered the wiring kit as well), but installing the wiring harness was quick and easy.

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

Haven't fully tested it, but installation was easier than anticipated. I recommend watching the video for options for routing the wires to the storage compartment in the CR-V. I cut a small slit in the corner, closest to the bumper, of the storage compartment and pulled the wires through. Honda provides a great place to store the wires! -A. 346354

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

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

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

Installed the trailer hitch receiver and wiring yesterday after reading and the watching the videos on etrailer and reading the product reviews. Products installed easily and, as noted by another reviewer, I did not need to drop the muffler. I have previously ordered trailer parts from etrailer and I highly recommend them. The parts are of high quality and reasonably priced. The videos were especially helpful to me as I had not previously performed an installation of these products. Thank you staff at etrailer!!! 389342

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

  • Recommended Trailer Hitch for 2005 Honda Pilot
  • Both Curt class III trailer hitch, part # 13328 and the Draw-Tite Hitch class III trailer hitch, part # 75599, are quality hitches. But the most popular hitch for your vehicle is the Curt hitch, part # 13328. Installation is relatively easy, even for a beginner. The Curt receiver simply bolts on to the inside of each frame rail. Both hitches require about 40 minutes of installation time. The Curt hitch does use two extra screws to attach the center bumper bracket above the receiver...

  • Recommended Fit and Compatibility of Components for Hauling a Trailer with a 2005 Honda CR-V
  • I checked out all the parts you listed ( # 13535, # 118336, # C45030, # 63845, and # C21500) and good news they will all work together. I do have a few suggestions for you though. I would instead suggest the Draw-Tite hitch # 75690 over the Curt hitch because if you decide to transport anything like a bike rack or cargo carrier in the future you will need to use a stabilization strap # 18050 per Curt's warranty and with the Draw-Tite hitch you won't. Next suggestion is we offer a...

  • Towing Capacity of 2000 Honda Accord V6 Automatic Transmission

On page 186, Honda states that the maximum towing capacity of the vehicle is 1,000 lbs and that the maximum tongue weight load (downward force applied to hitch) should be no more that 100 lbs. The Curt Class I hitch you referred to does indeed connect to the spare tire well. I would recommend the Draw-Tite # 24791 which attaches to the vehicle via the tow loop and the frame members.

  • Troubleshooting Trailer Lights Not Working After Installing Vehicle Wiring and Rewiring Trailer

Unplug the trailer and use a circuit tester, item # 3808 if needed, to test the connector at the back of the vehicle.

  • What is Purpose of Converter Box On Tow Ready T-One Wiring Harness # 118336 For 2004 Acura MDX
  • The black converter box on Tow Ready T-One Wiring Harness, part # 118336, is for use with vehicles, like your 2004 Acura MDX that have separate turn and brake light wires. Some vehicles send only one signal per wire, creating what is called a 3-wire system: one wire for the left turn, one wire for the right turn, and one wire for the brake signal (common on vehicles with amber turn signals). A converter will reduce it to a standard 2-wire system needed for wiring a trailer. There are still...

  • Comparing Draw-Tite and Curt Trailer Hitches for a 2003 Acura MDX

I can tell you that the Draw-Tite hitches do undergo a certain amount of extra voluntary testing that other brands do not do with their hitches. The extra 2 bolts and center mounting point on the Curt hitch do not give it additional capacity.

The left turn and brake light signals are carried in the yellow wire down the drivers side of the trailer, and the right turn and brake light signals are carried on the green wire running down the passenger side. This is the tried-and-true system that has been used for years. The converter comes in when you have a...
