Installation

This custom-fit T-One connector plugs into your vehicle's wiring harness, which is located in your rear cargo area, behind the driver's-side interior trim panel. Once you've plugged in the T-connector, open the fuse compartment beneath the driver's-side dash. Locate the fuse position indicated in the instructions, then insert the included fuse.


Once installation is complete, the 4-way flat connector will be stowed in your rear 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 vehicle'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 vehicle operate.


With a ModuLite, your trailer's lights will be powered without overloading your vehicle'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.

Video Transcript for Tekonsha T-One Vehicle Wiring Harness Installation - 2019 Honda CR-V

Today on our 2019 Honda CRV, we're going to be taking a look at and showing you how to install the Tekonsha T1 vehicle wiring harness with a 4-pole flat trailer connector.So here's what our wiring's going to look like once we have it installed, and it's going to provide us with a 4-pole flat trailer connector so we have all the required lights to get down the road safely like our tail lights, brake lights, and our turn signals. Now whenever we're not towing, our wiring is designed to stay on the inside of our CRV. We can simply lift open the hatch and we can store it right down by our spare tire. This will keep it out of the elements and we can make sure that we're not going to have corrosion buildup on our connector. And whenever we do need to use it, we can simply drop it out the back hatch so long as we stay away from the latch mechanism, the weatherstripping will provide enough cushion to where it won't damage our wire.Now, our wiring is custom designed for our CRV. We're not going to have to cut or splice into any factory wiring at all and in fact there is simply just going to be one connector that we're going to plug in behind this panel on the inside to get it working.

Now the installation, our wiring is very straight forward. However, there is a little bit of space constraints. It is very tight back here to get in there. So you just want to make sure you take your time and you don't damage any of the interior panels. But now that we've seen the end result of our wiring, let's show you how to get it installed.To begin our installation, we want to open up our rear hatch and we're going to remove any floor coverings that are in the back and we'll put all of them aside.

Then we'll come to the back threshold. This center section towards the inside is removable, so we'll just pop this cover out, set it aside, and then for the main piece of our threshold we're just going to start at the bottom and lift straight up, which will release the clips. We'll just work our way across until we can pull the panel out and set it aside.On the driver's side we'll have this tie down hook. It's going to be just inside our cargo area. We're going to want to rotate the hook towards about halfway open and we'll notice that there's going to be a very small little white plastic clip on the inside of the bezel here.

We're going to want to grab a small screwdriver and we'll find that white clip. You want to press up on the clip with a screwdriver and then at the same time pull outward on the hook. And then we can pull it out. The clips a little hard to see, but again, you just want to take your screwdriver, go in the center of it, press upward, and pull out and we can remove the hook.Now we're gonna move to our upper panel here. We're going to use a plastic trim panel tool and the main goal here is to pull the upper panel and the lower panel away far enough so we can get access to some wires back here.

So let's come behind our panel and I use my trim panel tool to kind of work my way going up to release those clips. Once we have it broke free a little bit, we can grab the panel with our hands and we should be able to pull it away.Okay, now once we have the panel pull back some we're going to be looking in the upper area and we're going to look for a connector that's going to match the one our new harness. To give ourselves a little bit more room, I'm going to come to this upper header panel here. I'm going to pull that down as well that way we don't have to worry about fighting this upper piece here. So just grab it on top and we're gonna pull straight down until we can remove it and set it aside.So if we pull our panel back, we can see that there's gonna be a white plug with some tape on it. Right above that, we'll have a factory ground point. We're going to get access to both of these spots, so we're going to pull a few more things off so we have a little bit more room to work behind the panel. So if we move just forward inside the panel here, we'll have the seat release on this lever. At the top, there's me a little notch. We'll take a screwdriver. We're going to push down on that notch. We'll take a screwdriver and we'll push down on that notch and it'll pop out the cover and expose two screws that are holding it in place. We'll grab a Phillips head screwdriver or Phillips bit and remove those two screws. And with those two screws removed, that'll give us a little bit more slack so that the panel can get pulled away.I'm going to take a knife and carefully cut the tape that's holding the connector in place. You just want to make sure you don't cut the wires on there. So free our connector, now we can grab our harness and plug it in. So we'll take our plug wind it up so we can plug it into the factory harness there. Now, you may hear a click. You just want to give it a quick pull and tug to make sure that it is locked in place.Now real close to the plug, we're going to have this white wire with a ring terminal. That's going to be our ground wire. Now we do have that factory ground so we can take a 10mm socket and remove the bolt, slide our ring terminal over it, and reinstall it. Now, I'm using a 1/4" drive with a short socket to break the bolt loose, because there is a very limited amount of space inside of here. Once you have the bolt removed, we'll grab our ring terminal, put the bolt through it, and you should make sure you put all the factory grounds back in places as well. Get it started by hand and then we'll tighten them the rest of the way up.And with the panel is still loose, we're gonna need to mount our converter box. Now, we get a couple of different options. We can use the eyelid on top. And the included zip ties, zip tied to some wiring. Or we can take the double sided foam tape and secure it directly to the surface. So we'll take the backing off one side of my tape, stick it directly to my converter box. I'm going to remove the backing off the other side. I'm just going to pull my panel back a little bit and if we look inside right here, we'll have a little recessed area where our box can sit completely out of the way. So we'll just tuck our box in there. Push it firmly against the side so it sticks in. And you just want to tuck your excess wire away from any points that it's going to be clipping in.We can take our 4-pole wire now. I'm going to put most of it in the spare tire area and I'm just going to wrap my wire down behind this panel, making sure that it comes out easily at the bottom so we can still get access to it. Now we can start putting all of our panels back in place at the rear hatch here.And the last step is going to be putting a fuse in place to activate our factory tow package. So we'll come to our fuse panel. It's going to be in the front seat towards the outside on the driver's side. So you'll notice that we have three rows of fuses. We're going to be working on this top row here. Now, ours already has in place. It's going to be the third one from the end, that blue 15 amp fuse. Now, if yours already has one in there, you're good to go. But if not, we can take the included 15 amp fuse from our kit and put it in place.Now that everything's back in place, we're going to test our wires to make sure that all the functions are working properly. We went ahead and hooked up our 4-pole tester and if you need one, you can pick one up here etrailer.com using part number I26. We can see that my tail light function is working properly, as well it was the left turn signal, the right turn signal, and my brakes. All we have left to do now is hook up to our trailer and hit the road.That'll finish up your look at the Tekonsha T1 vehicle wiring harness with a four pole flat trailer connector on our 2017 Honda CRV.

I just finished installing this hitch on my 2017 Honda CR-V. This hitch, wiring harness and wire plug mounting bracket ROCK! The instruction video was spot on down to the last detail. I fed the wire plug thru a plug hole in the spare wheel well by grinding a small notch in the hole. Cut the plug to fit the wire and sealed with silicone. The hitch fits like a glove and is perfect for me to pull my popup trailer. This was made easy by the video and expertly engineered hitch etc. I will use etrailer again and again! Great stuff, shipped right away, packaged perfectly, support was outstanding. 501289

One garage did not want to install it for me because they were sure it wouldn't work with my LED tail lights. Another garage accepted that I had double checked its compatibility with eTrailer and installed it with no problems. The lights work fine. 584198

The instructional video's were excellent. It took one person a little over an hour to install the hitch. Didn't even raise the car up. It took another hour to install the wiring. 450155

Great harness that does what it should. I would give Honda 2 starts for making it such a pain to get a man size hand into tight spaces to retrieve the wiring connector. Trying to get my hands around the connector in the car and cut the tape that held it in there was the toughest part. Once you have that connector pulled lose, the rest of the job takes minutes. 572357

Product great. Install IS HARD AND FRUSTRATING! And I'm still not finished - have cut the tape but need some help from smaller hands to connect. Couple of points: you do need to really push back on the top panel to get your hands in there at all. The connector itself is taped to an adjacent connector with brown tape - it almost looks like the white connector is encased in brown plastic but poking it a bit reveals it is tape and must be cut - force your way in with a pair of scissors. Someone else mentioned removing the green connectors from the loose body panels before really trying to squeeze in - that's a good idea as I lost one or two while pulling/pushing and squeezing hands in. The video is misleading - it is much harder than that makes it look (etrailer should mention this) but the product is fine and etrailer provides great service. This is for a 2017 CRV Touring. Good Luck! 480708

I ordered the products by telephone. The person at etrailer was very easy to deal with and the ordering process went quite smoothly. Hitch and wiring harness arrived quickly as promised. Videos were invaluable in showing how to install. The wiring harness is somewhat difficult to hook into the existing wiring due to the close quarters behind the panels, so be patient with this hook up process. Otherwise, the hitch installation went smoothly and was installed just like the video explained. The hitch looks very good on my wife's CRV. She is happy and I am happy with how it looks. Thanks. I will use etrailer in the future when our family needs a new hitch or accessories. 514537

The install went pretty smoothly. The video explains the process clearly. Be careful lining up the clips with the holes when snapping the trim back into place. I bent (nearly broke) a couple of the clips at first. You have to pull the panels with quite a bit of force to pop the clips free from the body. The video instructs you to drill a hole in the metal body for the ground connection. I realized after doing this that the ground wire may be long enough to connect to an existing screw in the sheet metal. Drilling the hole isn't terribly difficult, but space is limited for your drill, so it would nice to use a nearby screw. Overall, it was a pretty smooth installation. 386200

This harness works as expected once installed. The installation isn't horrible, but if you're uncomfortable popping plastic trim pieces loose in your car, it can be intimidating. You may have the plastic clips either break or pop out of the plastic trim and stay clipped into their mounting holes in the vehicle, which then necessitates your needing to pop them out by themselves and place them back in the plastic trim pieces, so you can snap everything back together when you're done. The instructions are OK, but the photos are not great. The installation video here on the web site does not match the written instructions completely. The instructions describe pulling the plastic panels out further to give you better access to the factory plug, as well as using a factory ground screw right next to the plug. The video shows barely pulling the panels out to reach the factory plug, and then supplying your own self-tapping ground screw and drilling it into the body of the vehicle. I chose to use the factory ground instead of drilling into my car. To access this area, you'll need to pull more clips to allow the plastic trim to be moved out of the way farther than the video shows. There is one part of the instructions that says to release a hook in the rear area that you need to depress a white clip. The picture is so poor that it appears to be pointing to the metal tie-down hook near the rear corner of the cargo area. I saw no white plastic clip there--because there isn't. The instructions are referring to the small, flip-down plastic hook about a third of the way up the driver's side rear corner of the cargo area, which looks like it's meant for hanging a plastic shopping bag from. If you flip the plastic hook about half way down, you'll see a white tab in the hook recess. You have to depress this with a screw driver or trim tool to release this hook from the body of the vehicle, allowing you to continue to pull the plastic trim out for installation of the harness. If you do not, you will break this plastic hook. Ask me how I know. Once you have pulled enough trim out to access the OEM plug and ground wire (which are right next to each other), installation is pretty easy. Route the wiring as you see fit, use the zip ties to secure the wiring behind the plastic trim, and mount the control box in a convenient spot. Just be careful not to drop any of the colored clips back in the recesses behind the trim panels. There's lots of room back there for them to hide. 366726

installed this on my 2018 Honda CRV. Installation went just like it was shown on the video. However, I could not reach the 10mm bolt to install the ground wire. I did not have a self taping metal screw. ...so have self taping screw handy. I followed a fellow review's advice and routed the 4 wires through the rubber plug (left side of the spare tire wheel well). It involved cutting and soldering of the wires.... But it was worth the extra time to have a professional looking installation. 520022


Comments
This T-One Vehicle Wiring Harness with 4-Pole flat does require a self tapping screw that does not come with the kit. Part # FA1131822 should work well to install the ground wire.

Product was delivered promptly and was well packaged. Installation was fairly simple according to the online instructions. Use a crowbar to pop the exhaust system holders off and let it drop as much as it will. Use a strap to support the pipe near the rear axle to keep it from hanging loose. I used a piece of stiff wire to hold the center of the hitch in place while I worked on installing the nits and bolts in each end of it. Space is limited so getting a torque wrench on the end nuts is quite difficult but can be done. You may find you a 3" to 6" riser on your hitch ball mount to keep your trailer level as the receiver sits pretty low. The wiring adapter wasn't difficult to install after I was able to determine how to remove the interior panels. Remove the top and bottom lift gate threshold covers and the plastic cover behind the rear seat s and the cargo hooks. Also remove the rear door threshold on the drivers side. This will make getting the lower rear side panel out to get access to the upper rear side panel. You don't have to completely remove the upper side panel to complete the install. So you can stay away from the airbag pin at the front top of the upper side panel. Everything worked after the install. I am highly satisfied. Check etrailer web site and YouTube videos for additional install hints and how to's for your install. I use the hitch to mount a bike rack, a cargo carrier, and to pull a kayak trailer depending on what my needs are at the time. 363024

This review is for the install only. I have not hooked up to a trailer yet to test the light system under load. If you read the actual Honda instructions they have you take most of the back of the CRV apart. This would have been hours of work. Instead, this install has you loosen a couple panels and work in a very tight space. If you have small hands and some good lighting, it is MUCH faster than the Honda way. As I got the panels loose, I used small 2x4 blocks to hold the panels open. You need some good lighting to see behind the panels once they are pried back. My biggest challenge was to get the binding tape off the connector that was way back and almost out of reach. Just getting that connector free of tape and making a solid connection with the trailer electronics took more time than the rest of the installation. The second challenge was getting a good ground for the system. The instruction paper shows hooking it up to an existing ground but on my CRV I could hardly see that connection and there was no way to reach it without risking damage by bending the trim panels too far. The instructional video shows putting a self-tapping screw into sheet metal behind the trim and using that for the ground, and that is the option I chose. Except no screw is included. I found an appropriate sheet metal screw in one of my several coffee cans of spare screws but I had to drill a small starter hole first. I have a small drill that worked well but a big drill would be a tight fit. I am a bit concerned because the video recommended a location that is thin sheet metal and I did not dare tighten the ground screw very tight for fear of stripping it out. hopefully it will maintain a solid connection. Next was adhering the control module into a pocket where it was out of the way, and finally routing the trailer wire into the spare tire bin where it is stored. Putting the trim back in place was easy and there is no sign of the work that was done. My CRV already had the fuse in place so hopefully everything is ready. Next I will pick up a trailer cable tester to make certain I have good power to the plug. 569476

Great customer service and nice people... Called me on a Saturday to follow up with my order !! Purchased the Draw-Tite 76128 for my Honda 2017 CR-V. Fit perfectly with no issues. Enjoyed the informative on-line installation video and detailed instructions that came with the unit. Had to release the exhaust hanger right behind the right rear wheel to get enough space to get a torque wrench on the 4 mounting bolts..not a big deal. All work was done WITHOUT requiring the vehicle to be on jacks or a lift !! Also installed the wiring harness 118741. The installation video was a big help and yes it is challenging to install only because of the small working space. Used 1 x 2's to help keep the work area open. To separate the connector from the taped bundle of wires, I used an exacto knife to carefully slit the tape and a long handled screw driven to peel back the rest of the tape to expose the connector. This takes a little bit patience, but it can be done. Used the I26 4-way tester to verify the wiring functioned properly before securing the interior panels, a real timer saver! Thank you etrailer for outstanding products and customer service...What a great experience overall !!! 699365

Installed on a 2017 Honda CRV AWD. This was a very difficult installation. The video is helpful and it is not complicated, but it is very difficult. There is simply very little room to get to the factory connector and the grounding bolt. I pulled back the side trim as far as I could hoping to not damage the entire piece and it pushes back at you. Could have used a couple more hands just to pull the trim back with force while I worked on the connector and bolt. The video does not say that the factory connector is taped to the cable and had to be cut to free it and access the side to plug into. The bolt for ground is very difficult to get to with a nut driver or socket - you cannot easily position your tools at the right angle without bending deforming the trim piece with force. You can get a socket wrench in there without an extender but then there is no room to rotate the wrench. The video showed using an angled motorized socket tool for a good reason - however most people don't have access to such a specialized tool. The video does not show how to run the connector into the spare tire well area - I reached down behind the trim as far as possible and just pushed and pushed and finally got it through - again not easy. The video says there are double sided tape and zip ties included in the package. Mine had neither, so I used my own zip ties. Also be careful with all the plastic clips that hold all the trim pieces in place, these are just held with a head into a slot and can pop out easily. One of mine dropped into the recess of the car body and could not be retrieved. I had to make a trip to the auto parts store to buy a replacement. Not sure why Honda makes access to the factory connector so difficult. This was a very frustrating experience. 560566

I installed the Draw-Tite 76128 Hitch, the 118741 wiring harness and the 18144 bracket to mount the wiring plug. You can route the plug through the hole that is provided for the factory hitch wiring (it will fit through, but it is tight) and use the bracket to clean up the install. It looks pretty sweet doing it this way. 398516

I am still very satisfied with the installation as well as the products. They were put to use about a month ago towing a trailer from Central Vermont to Southeast Ohio. That was about 800 miles and absolutely no trouble.

I was surprised to hear from George who has followed my purchase a year ago for this wiring harness. I had no luck trying to purchase a 2017 Honda CR-V wiring Harness. After an exhaustive search online I found etrailer.com, they had clear step by step instructions on how to install the harness so I knew it was the right one. I have towed a rental trailer over long distances and have had no issues with my wiring harness in summer, smoke, snow and harsh winter weather. Visibility is extremely important for both vehicle and trailer so as with other customers I would highly recommend etrailer.com for a quality purchase. 498809

Ordered this harness along with the DrawTite hitch #76128 and the 4 Hole Mounting Bracket #18144. Thanks to Ken K I was able to install the hitch with out help. I mounted the bracket on the welded mounting tab on the left side of the hitch tube. There is a grommet on the back left of the spare tire well for the factory wiring harness. Remove the plastic tail gate protector and pull back the insulation on the left rear corner to access it. You will have to cut the wire of the 4 pole connector about thee feet from the plug and later splice it back, I used some plug connectors for this. Make an X cut in the center of the grommet and feed the plug side of the wire through. I used some wire wrap on the external wire. Push the plug into the mounting bracket and using the screws and nuts provided mount unto the hitch tab. 391839

Product was good a worked as expected. Be careful removing plastic trim panels if you don’t remove the luggage hook you will bust it. I did not find any info about this in the how to video.

    For your 2017 Honda CR-V there are only 4-way harnesses we offer as custom fit options. For that you would want the Tekonsha harness part # 118741 which is a custom fit option. I like to recommend the Tekonsha brand as it tends to be the most reliable. I attached an install video for you to check out as well. Now if your trailer does not have brakes all you would need is the part # 37185 as an adapter to convert the 4-way to a 7-way. If you do have trailer brakes you would need the...

  • Where to Connect 4-Flat Wiring Harness on 2018 Honda CR-V
    If you have installed a hitch such as the Draw-Tite # 76128 on your 2018 Honda CR-V and still need to connect a 4-way harness, there is a simple plug-in option. The T-One Vehicle Wiring Harness # 118741 is a confirmed fit and will plug into the connection point in your rear cargo area. I have added a photo from the installation instructions showing the connection point and linked both the instructions and an install video for you to take a look at. Since you are going to be towing, I...

  • Attaching the 4-Way Trailer Connector to the Trailer Hitch Receiver on a 2017 Honda CR-V
    As you can see in the attached photo, the 4-flat trailer connector on the T-One Vehicle Wiring Harness with 4-Pole Flat Trailer Connector part # 118741 can be ran under the bumper and too the mounting bracket on the Draw-Tite Max-Frame Trailer Hitch Receiver part # 76128 which you can also see in the attached photo. However we have not had a chance to test this method on our own therefore could not provide instructions how to do so. Generally speaking there will be several rubber grommets...

  • Are Additional Coolers Needed to Tow With 2019 Honda CR-V
    Those are good questions and your 2019 Honda CR-V does have coolers already and additional coolers are not needed with the CVT transmission in this vehicle. I took a look at the owner's manual as well and it does address the issue by saying that towing a trailer will require you to change your transmission fluid every 25,000 miles, which is more often than if you were not towing. Since you do plan on towing, make sure you get the best equipment for your journey, and for your 2019 Honda...

  • Trouble Activating Liftgate on 2017 Honda CR-V After Installing Wiring Harness and Trailer Hitch
    I spoke with my contact at Tekonsha who said that you shouldn't be experiencing a problem with your liftgate on your 2017 Honda CR-V after installing the Tekonsha T-One # 118741. If you possibly cut or moved some wiring around other than what you needed to for the installation then that could very well be why you are having problems. I was able to see that you also purchased the Draw-Tite Max-Frame Trailer Hitch Receiver # 76128 for your CR-V as well. If the problem is that you are...

  • Parts Needed to Install Brake Controller in 2018 Honda CR-V
    Your 2018 Honda CR-V actually does not come with brake controller pre-wiring and you'd have to hardwire the brake controller. You will need to start with a 4-way (if you do not have one). For that you would want the # 118741. From there you would need to convert the 4-way to a 7-way so that you can install the brake controller. For that you will want the Brake Controller Install Kit and 7-Way Adapter part # ETBC7. I attached installation instructions and an install video for this...

  • Will Wiring Harness for 2018 Honda CR-V Drain Car Battery
    The T-One Vehicle Wiring Harness with 4-Pole Flat Trailer Connector # 118741 that fits your 2018 Honda CR-V will not drain your car's battery. It will only pull power when your Honda is actually on so, meaning it will not have any affect on the battery. I have added a link to a video of this connector being installed on an '18 CR-V for you to take a look at as well. For a trailer hitch on your 2018 Honda CR-V I recommend the Draw-Tite Max-Frame Trailer Hitch # 76128 because it is an...

  • Recommendation to Add 12V Power Socket on 2018 Honda CR-V
    To add a 12V power socket for you to draw 1-2 amps you will need to add a separate wire because you can't tap into your trailer connector # 118741. You can use the Hopkins 12-Volt Power Socket with Power Wire and Fuse Assembly # HM55115 or Roadmaster # RM-9332. Your other option since you will need to run wire anyway is to use an adapter like # ETBC7L which will give you a 7-way connection but only the 4-way and 12V power functions you can tap into. It will come with wiring and circuit...

  • Accessing the Factory Connector to Install Trailer Wiring on a 2018 Honda CR-V
    Either one is correct. If you try the method shown in the video for # 118741 but have a hard time reaching in there to get to the connector then go with the method shown in the video for # C56370. I have linked both videos for you as well as the instructions for each harness for your 2018 Honda CR-V.

  • Trailer Hitch and Wiring Recommendation for 2017 Honda CR-V
    For your 2017 Honda CR-V the hitch I would recommend is the Draw Tite # 76128 which is a confirmed Class III fit for your vehicle. Unlike the Curt hitch for your vehicle it does not require a stabilizer strap when carrying a non-supported load like a bike rack so it's the better choice. For trailer wiring you'd then want the part # 118741 which is a confirmed fit as well. Since you wanted to do some towing you might be interested in etrailer ball mount kit # 989900. It comes with...

    The trailer wiring kit part # 118741 that you referenced which is a fit for your 2017 Honda CR-V does not require any relays to install.

  • How to Remove Panels on 2017 Honda CR-V to Install Trailer Wiring Harness
    To install the trailer wiring harness # 118741 on a 2017 Honda CR-V there is a decent amount of paneling that needs to be removed or at least released. You'll need to take out the spare tire cover and then the scuff panel. Then there is a tab behind the rear seat release handle. Once you have the tab out you'll release the clips along the edge of the driver's side wall panel. I've linked a video that shows the install for you.

    I have attached an image of the correct wiring installation details on the Tekonsha T-One Vehicle Wiring Harness # 118741 for a 2017 Honda CR-V. This will be installed to provide a 4-way flat trailer connector at the back of the CR-V to power the trailer's signal lights.

  • Does Trailer Wiring for 2017 Honda CRV EX Require Running Wire Up to Vehicle Battery
    The trailer wiring harness for your 2017 Honda CR-V part # 118741 will not require you to run wires up to the vehicle battery. The power source the harness needs is present at the rear of the vehicle already as it's basically pre-wired from the factory for adding trailer wiring.

  • Is 6-Pin Connector There to Install Wiring Harness 118741 on 2018 Honda CR-V EX-L
    The 6-pin connector is definitely in your 2018 Honda CR-V, though sometimes, finding them can be a real pain. The best advice I can give you is just to continue looking, though it's difficult to orient exactly where you should keep looking based on your photos (I believe they are oriented to the side). I believe if you keep looking up above, and follow the wire loom you will find it. The connector may in fact be completely covered in tape and not obvious to the naked eye, but it will definitely...

  • Help Finding Connector for Installing Trailer Wiring in 2019 Honda CR-V
    It's possible you may have found the wrong harness to plug in the Tekonsha trailer wiring harness part # 118741 into. We had the chance to install this kit in a 2019 CR-V which I attached a link to the install video for that might be helpful for you to check out. Sometimes the correct harness can be harder to find as it can be buried behind other harnesses. If you check out install video around the 5 minute mark you'll see exactly where to find the connector behind the rear interior panels.

  • Tips for Flexing Interior Panels to Install Trailer Wiring Harness on 2017 Honda CR-V
    Judging by the short sleeves and the time of year the video for the # 118741 was made (appears to be spring time based on the install pic we took of the hitch that I attached), I would say most likely somewhere in the 70 degree range. It may not be super convenient, but if you are in a cold climate you could wait to do the install till you have a warm day, or wait till after you drove the vehicle for a while with the heat on to warm up the interior panels so they'll flex a bit more.

  • Parts Needed to Install 7-Way Trailer Wiring Connector on 2017 Honda CR-V
    You will need to start with a 4-way (if you do not have one). For that you would want the # 118741. Now if your trailer does not have brakes all you would need is the part # 37185 as an adapter to convert the 4-way to a 7-way. If you do have trailer brakes you would need the # ETBC7 instead of the # 37185 and a brake controller. This kit comes with everything needed to wire up the 7-way and install a brake controller. For a brake controller I would recommend the Prodigy P2 Brake...

  • Recommended Parts Needed To Install 5-Pole Round Harness On 2017 Honda CR-V
    Since you have a 5-pole round connector on your trailer, the easiest way to get a 5-pole on yoiur 2017 CR-V is to first install a 4-way trailer harness like part # Item # 118741. We do not have a custom 5-pole wiring harness for your vehicle. You will then need to cut the 4-way connector off the harness and install a 5-pole connector like part # PK11502. You will also need to use a single wire, # 10-1-1 to run the reverse circuit. I also recommend using a circuit tester like part...

  • 2017 Honda CR-V LX Trailer Wiring Recommendation
    That we are aware of all models of the 2017 Honda CR-V have the factory wiring install harness in the rear cargo area. There SHOULD be a harness at the rear of your vehicle but you'd just have to do a bit more digging to find it. It's pretty common for the harnesses to settle into harder to reach areas from being on the road for a while. That said you could hardwire in a harness like the part # 119250KIT if there truly isn't a connector on your vehicle. It would be just a matter of...

  • 2019 Honda CRV Trailer Hitch and Wiring Recommendation
    First let's start with the hitch for your 2019 Honda CR-V... for that the etrailer hitch part # E98848 is the way to go as it has a concealed crosstube which means it will be mostly out of plainsight. It's also made in the USA unlike the Draw Tite which also has a visible crosstube which makes it stick out a bit more. See picture. For trailer wiring you'd then want the Tekonsha kit part # 118741 as it installs very easily. The ZCI kit is great but it requires you to test the wiring...

  • Recommended Best Trailer Hitch Receiver When Comparing Options for 2019 Honda CR-V
    The Draw-Tite Max-Frame Trailer Hitch Receiver # 76128 , the Curt Trailer Hitch Receiver # C13397, and the etrailer # e98848 are all very similar. They will install in the same location on your Honda frame but they are rated for different load capacities and both of these capacity ratings greatly surpass the manufacturer towing capacity outlined in your owners manual, so I don't recommend making that the determining factor. The Curt # C13397 or the etrailer # e98848 is my recommendation...
