Installation

This custom-fit T-connector plugs into your vehicle's wiring harness. The connection point for the 4-way tow harness is located behind the interior trim panel in your rear cargo area. Once you've plugged in the converter, insert the included 10-amp fuse into the integrated fuse holder.


Once installation is complete, the 4-way 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.


Powered Tail Light Converter with Surface-Mount Technology

A tail light converter is built into this T-connector. This converter is a circuit-protected, battery-powered unit that bypasses the electrical routes that are used by a basic wiring harness. As a result, there is virtually no draw on your tail light circuits.


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 the trailer. This converter combines the brake and turn signal functions of your automobile so that they run on one wire to properly activate your trailer's tail lights. Note: This will not affect how the tail lights on your vehicle operate.


Curt builds each tail light converter using surface-mount technology (SMT). This method of construction involves soldering electronic components directly to the surface of a printed circuit board. SMT eliminates the need for leads, which are used in older through-hole technology. The result is a circuit board that is smaller yet provides more routing area and that offers superior performance, reliability and durability.


Curt SMT Circuit Boards

Circuit boards constructed using SMT have been shown to perform better under rough conditions with excessive vibration than those made using the through-hole method. And where would vibration be more likely to occur than in towing applications? Curt converters also produce less heat, leading to increased durability and longer life. In addition, lower levels of resistance ensure better performance, especially for parts that operate at higher frequencies.


Each Curt circuit board is made using high-quality components that are pieced together in the most technologically savvy fashion, leading to greater predictability and reliability in functioning.

Video Transcript for Curt Custom Fit Vehicle Wiring C56217 Review

Today we are going to review part number C56217. This is the Curt T-connector Vehicle wiring harness with the 4 pole flat trailer connector. This part is a custom fit part, includes everything shown here. It is designed to fit on the Toyota Highlander without the factory tow package, starting in the year 2008. What I would recommend is go to the product page and at the bottom of the page it will list the exact years and models of highlanders that this will fit on. This will provide a four way flat trailer connector at the back of your vehicle to power your trailer signal light.

Has a 4 pin plug on this harness here, this will plug into an existing plug on your vehicle. The power converter here, also has a 10 pin plug that would plug into an existing plug on your vehicle also has a slight wire with a ring terminal on the end you can see. This is needs to be grounded to a good clean ground. Does come with included self-tapping ground screw if needed or you can use a screw that is already on the vehicle. If youll notice on here there is a red inline fuse holder, it is made to hold the larger 10 amp fuse that comes in with the part, you just plug it in there and then you close it up and it also comes with a smaller mini 10 amp fuse that you would need to put in the fuse box of the vehicle.

It does also include these zip ties, if you have any wires that would be hanging down or get in the way you can use this zip ties to tie them up. Comes with the colors and instructions, has some very good instructions on how to install it. Comes with a piece of double face tape which you can peel off and that would be used to attach your converter to a nice location. Does come with this dust cap that you can install on to your 4 way, you just put that over there, and it has a cap that when you are not using it to protect the connections just like that. There are a couple of pieces these two butt connectors and this ring terminal they do included in this kit but for your specific applications those parts would probably not be necessary. This does connect quickly, easily there is no cutting or splicing the wires as I mentioned both of this would plug into plugs that are already in your vehicle.

The tow harness here has the 4 way connector on the end this will plug into a connection point in the rear cargo area of your vehicle and the power converter here will connect this 10 pin connector will connect to a 10 pin plug on your vehicle. The deference is, on a 2008 to 2013 vehicle, a 10 pin connector is usually located beneath the dash by the emergency brake handle and on the 2014, they moved this 10 pin plug back to the rear cargo area by this 4 pin connector. On the 2014 both of this will be close to the each other on the back of the vehicle. This tail light converter here will make it sure that your vehicle wiring will match that of your trailer. It is a powered module which will connect directly to the battery to avoid overloading you vehicles electrical system.

This converter is made of a surface mount technology and what that means is it gives you consistent reliable performance, it will maximize your trailer light yield and intensity while producing minimal heat that also give you superior operation in rough road connections . That should do it for the review on part number C56217 the Curt T-connector vehicle wiring harness with the 4 pole flat trailer connector. .

2015 Toyota Highlander


This product was cleared for my 2015 Toyota Highlander, so I purchased it thinking the instructions would be clear. They were to a point. I was able to install the harness with very little trouble. When it came time to install the 10 Amp fuse in the highlanders fusebox (under the hood), there was some confusion. The instructions specifically stated that the highlander fuse box would show a "towing" fuse location and that it would be 10Amps. I don't know if this is unique to the 2015's, but the fuse location marked "towing" on mine was labeled "30 Amps". BIG difference! I called support. They promptly answered and made a couple attempts at answering my question, but being an electronics engineer it was not really to my satisfaction. They first suggested that it was marked 30 Amps because if you installed the 2015 Toyota Highlander OEM harness, it was made for 7-Pin. WRONG! No such OEM harness exists for the 2015 and the OEM install direction clearly shows a 4 pin layout. The operator went back to the technician and came back with the answer, "install the 10 Amp fuse and if it blows we'll know it's a problem!" I did install a 10 Amp fuse they supplied. Don't mistake this for a negative review. My experience with etrailer has been good in the past, and good now. I'm hoping they will update their documentation to reflect my model vehicle and appropriate technical specifications. Etrailer is the best! 172397

Thank you for the query. The products I purchased from your company works so well one tends to forget about them. I have had no issues whatsoever and they perform as intended. Thanks again.

2008 Toyota Highlander


This wiring harness fit my 2008 Toyota Highlander Sport perfectly! It's very easy to install, especially if you watch the installation tutorial video. It's literally plug and play. Everything you need comes with it, including the fuse and zip ties to hold everything in place. The only hard part for me was getting under the dash and tucking everything away neatly, but that's because I'm a big guy and there's not much room down there. I ran mine to the outside of the vehicle to the hitch and installed it in a mounting bracket instead of leaving the harness inside the car and pulling it out every time I need to use it. There was an extra hole that had a rubber plug in it near the tail light area where the connector for the harness is. I took the rubber plug out and ran the wiring to the hitch. I filled the hole with silicone caulking on the inside and outside to prevent any water from getting in. I also wrapped all of my connections with electrical tape. The four way has a dust cap to protect the pins from dirt and debris when not in use. I installed it on the hitch using the mounting bracket (item 18144) here: https://www.etrailer.com/p-18144.html . Looks great! I tested my connections and everything works perfectly! Great product, great price, and you save a ton of money on installation by doing it yourself! Thanks, etrailer.com, for the great tutorial and product research! 499598

The customer service, as others have mentioned, is amazing. From the initial order confirmation through product install, they were very helpful. My hitch arrived bent and after a brief call to Bill in customer service, I was up and running in NO time. The online videos were super helpful, thanks!! 130916


Comments

Thanks for the follow up!It?s awesome. Works like a charm!A friend gave me some advice that sadly I didn?t listen to though. He told me, ALWAYS remove the ball hitch when not in use. That way when you walk around the back with groceries you didn?t hit the hitch with your shin! lol Sadly last week, after a year, i had my first encounter with the hitch while carrying groceries! lol Hopefully it?s my last.

I like that there is no splicing involved. Everything fits nicely. Of course the installation took me a little longer than in the video. The video may not be a 2017 Highlander as some parts look different, but it is very helpful. The installation instructions that came with the part are not as useful. The video suggest to route the wire to the trailer through the bottom of the lift gate. I found a rubber plug on the left side under the left side panel where I cut a slid in and now can leave the harness near the receiver all the time. I don't expect water to come in there but will monitor. A nice feature for the hitch would be a place to store the connector while not in use. P.S. I only got the harness from etrailer but should have used etrailer for the hitch hardware also. I was lazy and thought the competetor could do the job, but I would not recommend them. You may be lucky to find someone who knows what they do but I wasn't. They failed to re-install some of the plastic covers under the car and did not give me all the pieces they did not install back. So I had to spend time under the car and have missing pieces. One thing I noticed, however, on the trailer hitch installation video, they cut quite a bit of plastic off. I did not have to cut as much. So, before you cut based on the video, verify that it is actually necessary. 409666

Wiring harness on a 2017 Toyota Highlander Hybrid. I wanted to update you: -The hybrid has its battery In the well behind the driver's side rear wheel in distinction from the gas Highlander, which has its battery in the engine compartment. As a result the battery has a case over it that must be removed before the rear cargo tray can remove. A plastic pry tool applied as illustrated in attached photo can simplify its removal, which is otherwise difficult . -Because the battery is there, its metal anchor strap's tie down makes a convenient grounding point for the wiring harness . 438182

The hitch receiver itself is great; easy to install etc. The only glitch is the Curt T-connector harness. Item C56217 is designed to attach under the dash to activate that part of the system that is not activated in a vehicle without the tow package. The wire with the trailer connector is then attached to a pigtail next to the taillight. BUT, the instructions contained in the package indicate that both the wiring and the control box are to installed in the rear of the car. Perhaps that's true of another version of this product, but not this one. It works great when you wire it according to the manual...just not if you try to follow the instructions in the package. 130639


Comments

The harness that I received had two sets of instructions, one for a 2008-2013 Highlander, and the other side of the paper had instructions for the 2014 Highlander.The 2008-2013 instructions worked perfectly for my 2010 Highlander, which had the mount under the steering wheel.The 2014 Highlander supposedly has the mount in the back with the pigtail as you described. I dont know, I dont have this model vehicle.Make sure youre reading the proper side of the instructions when installing.

After much research I Ordered the 76156 Draw-Tite hitch for my new 2018 Highlander with the Curt wiring kit. Received all parts ordered complete, in less than 3 days . Quality of all items was First Class and etrailer price was hard to beat and I checked around. This was a Real great deal especially when you consider shipping was FREE. The Pictures and Video's on etrailer web site were so HELPFUL on making the buying decision and doing the install. It took me two days but I saved over $500 doing the job myself and it even turned out to be a better set up then the hitch the Toyota dealer was offering. See Draw-Tite Hitch Picture you can hardly tell the hitch is there. Amazing!!! Thank You ! etrailer Corp for helping to make this one of my better buying decisions and projects. . All in All -- NO REASON TO BUY HITCH OR TRAILER PARTS FROM ANYONE ELSE RW 461513

Hitch arrived w/in a week of placing the order, free delivery! Box was slightly banged up, but hitch was not damaged at all. Please note there is no interior packaging around the hitch. This was a self-install, one man job. Hint: watch the etrailer videos & other videos online as this will help a lot. I had no issues w/fitting the hitch but one of the tips I did use, was to reuse the box the hitch shipped in as support for the hitch during installation. I also used a scissor jack for final mounting to line up all bolts. I tightened to the recommended torque and was VERY pleased w/the final outcome. Passenger side under panel trim did not need trimming, drivers side did require a cutout but you can trim this smaller than the instructions detailed. Hitch looks great on my 2010 Toyota Highlander! Ordering from etrailer was easy & I would do so again, if needed. 181275

I purchased the trailer hitch and wiring harness at the same time. The wiring harness was simple to install, we watched the video and played it along side us as we did the job. The only thing I found was that the large white connector has to be tucked back up out the way or the 'trunk tray' won't fit back in properly. Everything went great, lights tested and worked.......and then where's my Leatherman? Looked all over for it and couldn't find it. Surely I didn't reinstall everything and leave it buried in the bowels of the car...........sure did. 456143

I just bought a new boat a month ago. I loved the boat but my SUV had no trailer hitch to tow the boat, so I went to Toyota dealer where I bought my brand new SUV at and asked for the cost of the trailer hitch. They told me the price of the parts (trailer hitch and harness wire) and 4 hours installation is $1578. Tell you the truth I did not know what is harness wire. So I went home go to YouTube and search for trailer hitch and harness wire. There are the wonderful video from etrailer.com. I ordered the parts and costed me $197 with 4 days delivery to my house. Installation? I turned the video again and follow step by step. With the help of my father-in-law it took me about an hour. So thank you very much to all the wonderful people from etrailer.com You all save me a lot of money and make my life easier. Along I send the picuture of me and my son first day to day in the boat on Potomac river Virginia. Thanks again 192672

Please read the product reviews before installing a Curt trailer hitch for a 2011 Toyota Highlander. The instructions for trimming the panels is incorrect. Nothing has to be done on the passenger side. Just bend it slightly to get it in place. On the driver's side, the printed instructions are wrong. A 1.5" cut not a 2.5" is what is needed. Follow along the edge of several small holes to the large hole near where the end is snipped away that portion of the directions are correct. I attached a photo, not sure it will be attached. Also loosely install the Curt trailer hitch on the driver's side first, otherwise it won't line up. Tolerances are bit short on the width in my opinion. But it's now on and working fine. 214617

Product works as advertised in my 2015 Highlander XLE. You need the C56217 even if your '15 model has the Towing Prep package (even Curt has erroneous info on their website). I initially just bought the flat-4 (unpowered) wiring harness and none of the lights worked. After this was installed, everything works perfectly. 213885

Great product and customer support. I installed this with a Draw-Tite hitch I also purchased from eTrailer. This is a super easy installation, the video makes this a no-brainer. Took me about 15-20 min in total. I contemplated punching a hole in the body to route the 4-pin plug, but when I got the panels removed I found there is already a ~1" hole with a rubber plug on the left side near where the controller mounts on a 2017 highlander. In the end I decided against routing outside of the vehicle and will just use the harness through the lift gate when in use. I don't tow that often and I think having the plug inside the vehicle when not in use will keep it free from the corrosion that always occurs on these plugs. But if you want to mount it outside, it would be pretty easy on a 2017 Highlander. Great job eTrailer team. You'll get my future business. 516691

The product works flawlessly and installation was easy once I got the cargo area opened up. However, the instructions were a little less detailed than one might hope. While installation is a simple matter of plugging it into the vehicle harness, it wasn't obvious to me how to pull out the plastic battery cover and tool tray. (You just pull up on them.) Then deciding where to stick the box so it doesn't rattle around. That all went OK, but it would have helped to have some more model-specific suggestions about where to attach the box etc. Also finding the correct location to add the fuse took some time. There are four fuse blocks in this car (1 under the dash, 3 in the engine compartment). Found the "towing" fuse position in the 2nd fuse block in the engine compartment. Hope that helps another 2018 Highlander owner :) 513454

As a mechanic during my college days back in the 60s and 70s, I installed many bolt on hitches. So, when I bought a 2012 Highlander that needed a hitch, I ordered yours. It was priced great, and delivered to Minnesota in a couple of days. My brother has taken a recent interest in fixing his own vehicles (with my help) was surprised that a hitch was a do-it-yourself project. With his tools and floor jack, and my breaker bar and torque wrench, we two old guys installed the hitch in under half an hour. The Curt electronics were also quick to install. My only confusion was the photo of a tailgate over the instructions where a photo of the driver's front door would have been more appropriate. It made me stop and visit your You Tube video that readily clarified the installation location. Good job all around guys. Thanks. 201894

I purchased this wiring harness for my wife's 2012 Toyota Highlander SE. The harness arrived in just 5 days and was in great condition. The installation was very simple because I watched the videos prior to purchasing. The harness fit just like expected and took about 5 minutes to install. Sandy J was so friendly and understanding when I called and explained how I ordered the wrong part. Unfortunately I was given incorrect information from Toyota when I called to ask if I had the tow package pre installed. Sandy allowed me to return the incorrect item and purchase the right one. In addition to the harness I purchased my hitch through etrailer. The site is very user friendly and easy to navigate. I would defiantly recommend etrailer. 241779

The hitch for my 2010 Highlander arrived ax. 3 days after I ordered it. Like most of the reviews I read, the box arrived with some small holes in it. Nothing major but you could tell that the hitch was just sliding around inside of the box. At some point it tried to poke its way out of the box. Inspecting the hitch showed it still was in good shape and no real damage had been done. Still, the packaging leaves a lot to be desired. As for the hitch - it installed without issue! All the bolts lined up and the instructions/video were easy to follow. It took me and a friend less than 20 minutes to get it installed! The Toyota dealer wanted $600 to install a hitch - this cost me less than $200. Thanks! 190233

I went to the local Toyota dealer after telling him I had a Highlander 08 without the trailer package in it what would be the cost to put it in this was his answer " o we have to take out the dash board and check the wiring we put it in but it took over 10 hours and the price was over a thousand" you know what I said to him . I ordered the kit from you company which gave me great service the install under the dash was less than 2 minutes plug it in and use the tie raps to hold it in place with the kit price on sale cost less than xx dollars Thank you very much. I also wish to add that I purchased the hitch from you and the fit was like a glove and the 4 pin wiring package was the best 319797

Great, as advertised product. Well packaged with everything needed including illustrated instructions. It took me all of 20 minutes to install. One item of note which has been mentioned in several reviews on the site: the instructions refer to installation of a 10 a "towing" fuse in the fuse/relay panel under the hood. However, the legend on the fuse panel lid indicates a 30 a "towing" fuse. Knowing there would be no risk to the vehicle wiring by using a lower amperage fuse I installed the provided 10 a fuse and have experienced no adverse effects as of yet. But for the sake of those who aren't so mechanically/electrically inclined, please revise your instructions. 433509


Comments

Jimmy, you will want to use the included 10 amp fuse that came with the wiring harness. The amperage rating of the included fuse was chosen because if the voltage exceeds 10 amps on that circuit, the wiring harness will fail, rather than the delicate circuitry of your vehicle.

Product works as promised for my '16 Highlander. Used included 10 AMP micro-fuse in 30 AMP Highlander towing fuse slot as directed. Lights work - no problems. For others ordering a trailer wiring harness for your '16 Highlander with towing package, be sure and order the harness WITH the converter. The converter was not a part of the towing package for my '16 Highlander, nor was a towing fuse inserted in the fuse box. So, get the etrailer harness, with converter package and you'll be all set. The converter package also contains all the necessary fuses, a grounding wire, dust-cover, wire ties, etc. that you need to get the job done. 242104

I bought a hitch class 3 Curt and the wiring harness for a 2016 Highlander. This is an easy install that took about 20 minutes using the you tube video as reference. skill level 1-5 = 1. If you can plug a plug into a wall outlet you can do this install. Good price and customer service. First hook up all lights working. Fast shipping, the right part the first time, decent price, plenty of DIY info and plenty of interaction with the company peeps. I usually dont give 100's because there's always room for improvement .. but these guys are doing it right. .. a pleasant breath of fresh air. Ill be coming back. 306165

Received on Saturday from USPS . I had already read installation instructions from their web page. Every step was outlined with both written instruction AND photos. I cautiously removed all the carpeting and covers as directed, installed the product, secured the wiring, and reinstalled the bin, covers, and carpeting in 45 minutes. I have already checked the system and it works flawlessly. I wish every product I purchased came with the detail and clarity this product did. If you can read you can install this product. If I can buy it from Curt they will be the place I can purchase it from.. OUTSTANDING company. 447128

Ordered Curt Class 3 Hitch Receiver and custom T-connector Wiring Harness for 2015 Highlander. Order dispatched immediately Monday morning. Delivery as promised Thursday. Box was pretty badly beaten up and harness had been expelled from separate clamshell packaging. Nothing appeared damaged and all parts (except for 10 amp microbus for vehicle fusebox) were present. Video instructions for installing both parts were excellent and was able to do install in about 2 hours (don't have a lift and was working by self). Now just have to see if wiring actually works when I go rent my trailer. Thanks 405621

Bought the Curt hitch and custom wiring kit for my wife's 2016 Toyota Highlander. It was shipped promptly in excellent condition. Was a delay in getting it installed because of other things. Put it on today and am thoroughly pleased with the quality, ease of installation and provided instructions. I contacted customer service to clarify placement of fuse in engine compartment fuse box. Instructions said look in owners manual. It did not tell. Staff sent a picture showing exactly where it went. I highly recommend etrailer to anyone in the market for their products or service. 372250

The product seemed high quality and came from etrailer in 3 days like they said. Everything fit well but the installation instructions were incomplete and poor. The one thing that bothers me is that the flat 4 harness does not connect outside of the car but Curt has it connect and stored inside the car. To use it you pull it outside and close the cars hatch door on it; seem funky. Everything is prewired in the Highlander and I wonder if there is an outside connector for the flat 4 wire harness. I contacted etrailer with questions about the instal and they were very helpful. 170416

'18 Highlander Limited - Installation video was spot on, easy install. One change I made was running the plug wires up into the cargo compartment via a rubber grommet located below the left taillight. Once you remove the bin located there it is exposed on the floor. I purchased some 1/2" plastic flex tubing ($5) from hardware store and covered the wires that were routed out of the grommet to the hitch mount. Dab of silicone to seal hole in rubber grommet for good measure. Big thumbs up to etrailer for instructions and videos for both the Draw Tite hitch and wiring. 459307

Ordered 2nd day delivery but UPS didn't make it until noon (2.5 days) and I wasn't able to install it at my shop along with the Curt hitch. Had to come back to condo garage for wire install. Everything worked great and as advertised with one exception. The grounding cord eye was just a little too small to fit the closest grounding bolt so I finally had to clip it off and put on the larger eye provided and of course didn't have the right tools in my condo. Hooked up rental trailer yesterday and everything works fine. Nice job on the install video! 367729

Installed perfectly on my Toyota Highlander. I had the advantage of being able to take my vehicle to a friend's local garage and use his lift. It took less than 30 minutes including trimming the two pieces of plastic on the underside. Literally bolted in place flawlessly. I installed the wiring harness in about 15 minutes and it is fully ready to use. Watch the video of the installation process on etrailer website and it is very easy to do. I was lucky to have a second pair of experienced hands but this could easily be done by a complete novice. 305371

This is my 3rd etrailer purchase. And like the previous 2, this one fit like a glove on my 2017 Toyota Highlander. etrailer's installation instructions are very clear and when combined with the on-line videos the installations are straight forward. I would also recommend the 4-wire wiring tester sold by etrailer. It is very slick to check out the wiring installation as well as to have in your glove box for any future trouble shooting, although I have never had any issues with the wiring or hitchs. All of my hitchs have been the CURT brand. 401267

The hitch was exactly as described. The packaging of the product was inappropriate for a heavy metal product - it was loose inside a large corrugate case. In shipping it was bent, as other reviewers have mentioned. (Some wooden bracing inside the case would be more appropriate.) Fortunately I have a friend with a large vise who was able to straighten the bent section. After that, installation was relatively easy (for two people). The wiring harness was particularly easy. In use for towing a trailer, the hitch has been trouble free. 288877

Great product. Great directions. This was installed on my 2017 Highlander Limited. I really was not a fan of the trailer connection harness dangling out the bottom of the cargo door, so I added some split flex tubing and went through an empty rubber grommet to the underside. It had plenty of room to reach the 2" receiver hitch. Straight forward and easy to do if you can follow directions well. I do find it funny how some people are complaining about the 10amp fuse that was sent with this kit. It's a good thing... 340043

I ordered this product as opposed to the $250 from the dealership for a fraction of the cost. It exceded my speciations with a fast delivery and how easy it was to install. I bought it for a 2018 highlander with no cutting or splicing wires, the instructions tell you the 10 pin wire is in the front by the break and e brake... is not there. Is located in the trunk under the cover where the tire replacement kit is. Now I can tow without a problem and without paying dealerships $550 they wanted labor and parts. 520029


Comments

On a 2008 to 2013 Toyota Highlander, the 10 pin connector is usually located beneath the dash by the emergency brake. On the 2014 and newer they moved the 10 pin plug back to the rear cargo area by the 4 pin connector.

I was able to install this product by following the instructions and this was not a difficult task. The product was delivered as explained and worked upon install. The quality is good, I am a little concerned about the longevity (quality) of the product due to the gauge of the wires and how this is hooked up in the Toyota Highlander. When the harness is being used it is crimped by the trunk storage compartment and the liftgate. After years of use, if used often, I can see this design being an issue. 384706

The technical support was exceptional and the representative that I spoke with knew exactly what I needed for my particular vehicle. The package came with good instructions (with pictures) and a significant amount of additional parts (fuses, zip ties, etc.) that made the installation very easy. One comment would be that while the package did come with all of those extra parts, it was not made clear what some of them were for. (such as the extra fuses) Oh, and the price was very reasonable as well. 190637

Product page says "quick and easy install" and it was just that. I watched the install video and may have referenced the instructions once or twice max. The installation video showed installation on my specific vehicle and went through all of the steps in detail. This truly is a plug and play install that takes no more than a few minutes. Just plug it in, hide the wires, do a quick test, and you're ready to go. Thanks again etrailer for quality products, low prices, and great customer service. 239181

The installation video I found on the product page is exceptional. It made the installation a snap for me. I don't have any experience with these types of installations nor do I have an understanding of how the wiring is configured - I don't need to with this product. After viewing the video on my computer I probably could have done the installation but I viewed it on my phone as I did the hook-up and was able to do the job in minutes. I tested it with the I26 tester and it works perfectly! 443407

The product arrived in an open/damaged box. But that is the end of the bad news. Everything appears undamaged and all is accounted for, less installation instructions, which I assume were lost. Everything I needed for the install is on the website anyway. The installation was ridiculously easy. Probably 30 minutes or less and I had my 16 yr old son do most of it. I helped him with the actual hitch install. Sweet! The packaging is the only thing keeping it from being excellent. 141565

The trailer hitch and wiring harness for my 2013 Toyota Highlander arrived more quickly than expected. The installation videos here at etrailer.com for both were helpful, and the packaged instructions were adequate too. I didn't have any problems with bolt hole alignment, though I did manage to cross-thread my last bolt (isn't that how it always goes?). I would advise having another person help you hold the hitch as you install it. Overall, I'm very pleased with the products. 227969

I installed the Curt hitch on a 2013 Highlander. I chose this hitch, because it allowed me to keep my full size spare tire mounted underneath the vehicle. Directions were easy to follow and the steps straightforward. Couple of items to consider: Make sure you have a long handle socket wrench (or impact wrench) to remove the tow hook bolts. Having a second person is helpful when lifting the hitch in place and inserting the bolts. Approximately two hours to install. 235831

I was told by Toyota that I did not need this part. Turns out I did. Very easy to install, clean installation, all the parts needed are included and works as advertised. Pictured is a 2017 Toyota Highlander, with etrailer (Curt) hitch and etrailer (Curt) 7 way/4 way plug. 449240

2013 Toyota Highlander


The wiring harness is easy to install, however, the printed and video instructions are a little misleading. My vehicle is a 2013 Toyota Highlander and the towing fuse receptacle calls for a 30 amp fuse and the slot would only accept the very smallest of the three 10 amp fuses supplied. Also I had to remove the small ring connector and attach the supplied larger one in order to attach it to the stud indicated in the video. I am overall pleased with the harness. 231708



- C56217

The wiring harness arrived on time, as promised. The printed instructions are very good, and the website video of an actual installation is even better. Now I have trailer wiring kept inside the car, so no chance of salt corrosion on the plug. It took a third and fourth look to establish the exact location of the fuse needed in the engine compartment. etrailer carries quality products, at a great price, and makes it easy to diy. Thanks etrailer. 485838

Works great. Straightforward installation. I chose to run the wiring through a rubber grommet in the bottom of the storage well and along the underbody panel and rear bumper facia to a mounting bracket I attached to the hitch (the little mounting bracket ledge on the DrawTite hitch is a nice touch). I did this so that I wouldn't have to get out and then store the trailer plug each time I wanted to use it as suggested in the installation video. 400121

Excellent experience from the product advise provided by the sales specialist, to ordering, shipping, and delivery of my purchase. Adam E was awesome as he directed me in purchasing exactly the equipment and accessories my vehicle needed to compliment it's tow package. While my purchase has yet to be installed, everything looks to be of excellent quality. I would not hesitate to work with Adam E and to do business with with etrailer again !!! 466624

  • How To Tell If 2016 Toyota Highlander Has Factory Tow Package Wiring
  • I cannot say for sure how you can tell whether or not you have the converter on your Highlander but I can help you out with the trailer harness installation. The only sure way to tell which harness you need is to check out what wiring you have in the rear cargo area. If you watch the attached videos you can see where the installation differs. If you remove the back tray in the rear cargo area of your Highlander you can see if there are two connectors, one being bigger than the other....

  • How to Determine if a 2012 Toyota Highlander has a Factory Tow Package
  • The best way to determine if your 2012 Toyota Highlander has a factory tow package is to have a Toyota dealer run the VIN number in their computer system. They can tell you how the vehicle is equipped that way. If they say you do not have the tow package use harness # 118449. If you do have the factory tow package use # 56042.

  • To send me your picture you can just reply to me here. To me that connector you found sounds like where you need to plug a converter in which would mean you don't have the tow package. Look at the picture I've attached. If it looks like this will plug into the connector you found then that's what it is. It shouldn't be a connector for a brake controller because your 2018 Toyota Highlander doesn't have a custom adapter to install a controller. If this is what you need then I recommend...

  • What Is different Between Curt And Tekonsha Wiring Harness For 2016 Toyota Highlander

Both the Curt wiring harness, part # C56217 and the T-One Vehicle Wiring Harness, part # 118449 harnesses plug in the same way(behind the tail lights), and both have a powered converter.

  • 2015 Toyota Highlander XLE Trailer Wiring Harness Recommendation
  • The Curt Harness part # 56042 that you referenced is designed as a replacement harness for vehicles like your 2015 Toyota Highlander that came with a factory 4-way. Although Toyota said you have the factory tow package it sounds like you are missing the necessary under dash converter. This is a Toyota part that they might be able to set you up with, but we don't carry it. The best solution I can recommend for you would be to get the part # C56217.

  • Where is the Underdash Connector to Install Curt Wiring Harness # C56217 in 2014 Toyota Highlander
  • The connection point for the 4-way tow harness is located behind the driver's-side interior trim panel in your rear cargo area. The ModuLite plugs into the factory wiring harness beneath your dash, on the driver's side. Once you've plugged in the ModuLite, locate the "towing fuse" position in your fuse box and insert the included 10-amp fuse. Once installation is complete, the 4-way flat connector will be stowed in an out-of-the-way location within your cargo area.

  • How to Determine if 2015 Toyota Highlander Is Equipped with Factory Tow Package Wiring
  • The quickest way would be to call the service department at your Toyota dealer. If you provide your VIN, they should be able to look up your vehicle and determine if it's equipped with the tow wiring package. You can also check the fuse box as shown at the 4:00 minute mark of the video I've linked. If there's a fuse already installed, then you have the tow package and would use the # 56042 harness. If there's no fuse in place, you'll need the converter and the harness, part # C56217. Toyota...

  • How to Determine Towing Capacity for 2010 Toyota Highlander, Hitch and Camera Recommendation
  • To address your first question about the capacity's of the Curt Hitch # 13534 and your 2010 Toyota Highlander you must always go with the lowest rated component in a towing setup as the overall towing capacity. So since your vehicle is rated at 500 lbs of tongue weight you would gain nothing by going to a higher rated hitch. In other words the Curt hitch you referenced would work very well for you.

  • What are Differences Between Curt Wiring Harness # C56217 and TowReady Harness # 118449
  • Both Curt wiring harness # C56217 and TowReady # 118449 are fits for the 2015 Toyota Highlander without the factory tow package. They differ in their maximum current output capability. The Curt harness has a maximum output of 3-amps per stop/turn circuit and 6-amps for the taillights. TowReady harness # 118449 has a maximum output of 2.1-amps per stop/turn circuit and 5.6-amps for the taillight circuit. Generally its best to have more capacity to help ensure you do not overload the harness.

  • The Curt hitch part # C13200 has been confirmed as a fit for your 2016 Toyota Highlander and would be an excellent option. It will allow you to keep the full-size spare, but since the tube of the hitch covers a portion of the tire (see picture), you will have to angle the tire as it is lowered/raised.

  • Can the Curt T-Connector # C56217 be Run Through Plug for Permanent Installation on 2015 Highlander
  • You most certainly can run the wiring and connector of the Curt T-Connector # C56217 through the rubber plug in the rear of your 2015 Toyota Highlander. After cutting a slit into the plug and running the wire and connector through you will want to use some Sealant # LT37464 to re-establish the seal that the plug had. To install the connector next to your trailer hitch receiver you will want to use the Mounting Bracket 4-Pole Flat # 18144. For an easy install you can use the Short # 18140...

  • Finding the Brake Switch Wire to Install a Brake Controller on a 2014 Toyota Highlander
  • You have to test the brake switch wires with a circuit tester such as # 3808 to determine the correct wire for a brake controller red wire. You want the wire that only has power when the brake pedal is pressed and not with the headlights or turn signals on. On a 2013 Highlander we installed a brake controller on, the brake switch wire was blue. I would start testing with the blue wire on the brake switch if applicable to your 2014.
