CURT custom wiring connectors are the easiest way to outfit your vehicle with a CURT trailer wiring connection. They are built with some of the most advanced technology in the industry, and each one is custom-fitted to work with a specific make and model. Some automotive manufacturers install a special socket on the vehicle to be used for vehicle-to-trailer wiring. Although this special socket is not equipped on every vehicle, a CURT custom wiring connector -- also called a T-connector -- utilizes the socket for simple, stress-free installation. Rather than requiring you to cut, splice and solder into your vehicle's wiring system, the custom wiring connector uses a single OEM-compatible plug and instantly provides a standard, universal vehicle-to-trailer wiring connection, typically in the form a 4-way flat. All CURT custom wiring connectors are made vehicle-specific for the easiest possible installation and the best fit. This particular plug-in connector provides a 4-way flat socket and is designed to be a custom wiring option for certain years of the Toyota Highlander and Lexus RX350 (factory tow package may be required; to verify your vehicle compatibility, see application info). It comes with all necessary hardware to establish a solid connection. It also comes with a dust cover to keep the connector socket clean when not in use. To ensure long-lasting reliability, all CURT custom wiring connectors are thoroughly tested for optimal functionality. Stress is the last thing you should feel when towing a trailer -- whether you're hauling your RV to that favorite camping destination, your ATVs up to the hunting grounds or your fishing boat to the new hidden hotspot. At CURT, we think your towing equipment should add to the enjoyment of your experience, not detract from it.

I'd previously rated this a one star for not fitting the 2013 Highlander but It probably does. The instructions were unclear and I was looking at the wrong white connector under the dash. I've already returned it so I'll never know. I rated it a four, minus one for inadequate directions.U-HAUL has some great installation videos specific to the 2013 Highlander on YouTube if you're adding a tow package. There's a video on installing the physical hitch and a second video on installing the wiring harness. They're great. I wish I'd watched before returning this. It could have saved me a re-order.

Let me preface this by saying this was the first time I installed wiring on any car. Fortunately, the connectors for this harness are already in the back of the Highlander, so after finding a Youtube video showing how to install it on our vehicle, it only took me about 45 minutes to an hour to get this harness installed and working. Picked up a $7 four flat tester on Amazon and everything seems to be working great!

A lot of products will advertise as plug-in play and they never ever are. This wiring harness, however, was the easiest aftermarket installation I’ve ever encountered. It was literally plug-in play. The only thing to be aware of is they give you a 10 amp supplied fuse to put in the engine bay fuse block for the towing package. My particular application needed a 30 amp fuse so I had to go out and pick one of those up. That was the only issue that I would highly recommend this harness to anyone who’s putting an aftermarket hitch on a 2018 Toyota Highlander

Very easy to install following different youtube videos (Curt, etrailer, etc). For my highlander XLE 2019 it was just plug and play, probably the instructions are not clear but search for a video and you will install it very easy, and most important, IT WORKS! Cheaper that the one the toyota dealership wanted to sell me but with great quality.

So as most folks said this is very easy to install. I installed it in a 2015 Highlander Hybrid. Plenty of videos on the Internet as to how to reach the wiring in the back of the vehicle so check those out. But there are a few things you should know and reading this should make it easier for you than it was for me.Once you get to the point where you have removed the pieces and hooked up the two connectors, you have two decisions to make. First is whether to drill a hole for the ground wire screw provided or use a screw or bolt already in the vehicle. I chose to drill the hole, sand and that's the best option in my opinion because you don’t need to sand any nuts or screws and you can put that screw where you want it--there are plenty of safe places to drill in the rear near where the adapter plugs in.The second decision is where to put the 4-pin plug (inside or outside the vehicle). I think the best option is to leave it inside the vehicle unless you will be using it a lot. You run it to the compartment where the spare tire tools are. I ran it through the piece of plastic that goes over the battery--see the picture (non-hybrid owners will not have a battery in the back), When you leave it there, it’s easy to get to--you never see it unless you use it and you don't need to worry about running it under the car and mounting it somewhere. Also, if it is outside the vehicle it can corrode, the wires can be cut, it can be damaged, etc. The only downside is it sticks out the back of the vehicle when in use, so if you are anal and don't want to see the wires then run it under and mount it.If you do run it under, the hybrid drain hole is in a different place from regular Highlanders, or at least it was from the one I saw in the video for a non-hybrid. In a hybrid, it is between the battery and the rear at the bottom—you’ll probably need a light to see it. I was confused by a video of a non-hybrid which showed the drain plug against the back of the vehicle (i.e., the hole points out the rear of the vehicle rather than down to the pavement as it is in the hybrid).As to the 10 amp fuse (the one that goes in the vehicle not the inline one in the adapter) the instructions say to consult the manual as to where to put it (there were two in my kit you only need one plus the inline one so you’ll use 2 out of the 3). Well, I could not find where in the manual to put the "trailer" fuse, but I watched the etrailer video and kind of "guessed" where it was from that. First, the fuse box is under the engine hood and it’s the main box (there is more than one) --see the picture as to where that fuse goes. There were only 2 possible places for it and it's the one closest to the front of the vehicle.Next, you must test your installation. If you do not have a trailer to hook up to it (or even if you do) there is a very cheap (under $7) and easy solution. Do yourself a HUGE favor and buy a tester. They are cheap and I don’t care if you are an electrician and have all kinds of ways to test it, this is so easy using a generic tester is not worth the extra trouble to save $7. I bought the SeaSense EZ TROUBLESHOOTER Circuit Tester here on Amazon and highly recommend it. Did I mention you should buy the tester?Finally, once you reconnect the negative post on the battery and clean up, you’ll try to close the hatch door with the button on the door, it is probably going to beep at you and not close. The reason is that you disconnected the battery (assuming you do during installation and you should) with the door open the door "open/close sensor" won’t know whether it's open or closed hence the beeping. Close the door manually and it should work fine after that.

I'd bought a new 2016 Toyota Highlander New Year's Eve and needed to get a receiver hitch and wiring installed. I was seeing quotes of $1,000 and above for the dealership to install. A truck accessory business near me quoted almost $500.00. I watched a few videos on YouTube and read some instructions and reviews online and decided to attempt it myself. I ordered Curt hitch #13200, the Curt #56217 wiring kit, and a rubber Toyota hitch cover all for roughly $225.00. It all showed up in a reasonable amount of time, all packaged well enough and my only surprise was the beefiness of the hitch. I spent a few hours Saturday installing the wiring which was my biggest concern but it was actually quite easy. I drilled a small hole for the ground wire and ran the wiring underneath through a rubber grommet on the drivers side of the vehicle. I sealed up the grommet with some silicone and used electrical grease on the connections to ensure good contact. I wrapped all of the wire that exited the vehicle with that black plastic tubing material to protect it from rubbing anywhere. I'd bought a 5' extension from another retailer as I thought that this wire might not reach my trailer. But it seems long enough and I noticed that this wire was a heavier gauge (better quality) than the extra extension cord. Sunday I installed the hitch itself and borrowed my wife's help for about ten minutes to lift the hitch up into place and start the bolts. This entire installation could of gone faster but I'm very particular and meticulous. The hitch looks good, the videos that I found plus the instructions made it all a breeze and I'm proud of how it turned out. I have yet to pull the trailer but I pulled it for years behind another vehicle with a class II hitch so I know this will do just fine.
