Perfect fit for Toyota Highlander. Easy to install.
by: BobR05/05/2024
This wire fit perfectly in my 2019 Highlander but I was never able to use it. I didn't realize that I needed the factory tow package for this to work, the label wasn't on the listing at that time. I ended up having to purchase one without the factory two option.

Toyota Highlander
I installed this product on the Toyota Highlander I inherited from my sisters estate. I purchased a 5' x 8' trailer to pull behind it. I discovered the wiring harness was too corroded to work. Found Hopkins Custom Fit wiring harness on-line, it installed easily and works well. I just keep the harness in the back of the car and feed it out the back hatch to connect to the trailer. Works good!

Connectors match factory harness on my 2015 Highlander, but, of course, it is missing the strain relief, protection and gromet. External flat plug is an exact match so it will fit the factory bracket, but the plastic mount (HM48595) they make for this is better, just get a couple of stainless steel screws and nuts to attach it and you won't have a rusted mess like the factory bracket. I ended up splicing the external plug onto my factory harness to replace the factory plug with a broken off ground pin. This seemed the simplest way to keep all the factory strain relief, etc. Would have preferred the splice not be under the car, but I'm hoping adhesive lined heat shrink will protect the solder joints adequately.

2008 Toyota Highlander
So easy. and I found a useful [online] video. I love that I can leave the wires in the storage compartment inside the car and just run it under the weather stripping on the rare occasions when I need it. Trailer wires have always tended to get rusted out in my experience. super easy!
by: Charles03/27/2022
This wiring harness came in really fast as well with the hitch but I made the mistake and ordered the wrong one so I'll be returning it for a refund. I don't expect any issues with that either!
by: James 06/15/2021
harness was plug and play and install was easy. One trick I would says is just remove the plastic base trim at the door latch and then lift up the storage tray to get the plug. No need to remove the whole tray and such.

- 4-Way Trailer Wiring Harness Recommendation for 2018 Toyota Highlander with Tow PackageYes, the Hopkins 4-way part # HM11141825 that you referenced will simply plug right into the port at the rear of your 2018 Toyota Highlander and then you'd be ready to go. I attached a picture of where you'll find the port at for the harness on your vehicle as well as an install video for you to check out too.

- Towing Capacity and Recommended Trailer Hitch and Backup Camera for 2018 Toyota HighlanderI took a look at the online version of the owner's manual for your 2018 Toyota Highlander and found that if you have the 2.7L engine it can pull a trailer that weighs up to 1,500 pounds. If you have the larger 3.5L engine the Highlander has a towing capacity of 5,000 pounds. For a trailer hitch that will work great I recommend the Curt Class 3 Rround Tube Trailer Hitch # C13200 because it has great capacities(more than you will need), and can be used with a weight distribution system....
view full answer... - Recommended Trailer Hitch Receiver and Wiring for a 2014 Toyota Highlander with Spare TireThe Curt # C13394 is a confirmed fit for your 2014 Toyota Highlander, however, in our installation notes we have that you will be able to store a full sized spare underneath after the hitch is installed unless the spare is on an aluminum rim. The aluminum rims are too wide to fit. If your Highlander has the factory tow package (converter under dash) then I recommend going with the Hopkins Plug-In Simple Wiring Harness with 4-Pole Connector # HM11141825. If it doesn't have the factory...

The Curt # C13394 is a Class III hitch with a 2" receiver and has a maximum tongue weight capacity of 500 lbs and a maximum towing capacity of 5,000 lbs though you will need to check your Highlander's owner's manual to find out what the vehicle's towing capacity is and make sure you stick with whatever the lower rated figure is.

- How to Determine Correct Trailer Wiring Harness for 2019 Toyota HighlanderTake a look at the rear of your 2019 Toyota Highlander in the spare tire compartment. You should be able to find a white connector like you see on the right hand side of the picture I've attached. If there is nothing plugged into that connector then you don't have the tow package. If there is something plugged into it, it should be a wiring harness with a converter (like is shown) which means you do have the tow package. If you do have the tow package I recommend the Hopkins harness,...

- Which Hopkins Wiring Kit Is Needed to Install A 4-way On 2010 Toyota Highlander Without Factory Tow?Since your 2010 Toyota Highlander did not ship with the factory tow package you will need the Hopkins Plug-In Simple Vehicle Wiring Harness # HM11141845. The Harness # HM11141825 is only a replacement section for the 4-way connector. This must have either the factory section or Hopkins section included with the Harness # HM11141845 to operate. As long as your trailer does not have electric brakes or require some sort of charge line or reverse wiring you will only need the 4-way flat to...
view full answer... - Recommended Complete Towing Setup for 2017 Toyota Highlander SLE AWD for 3,850 lb TrailerI'm happy to help you get what you need for towing. I did a little research to find your 2017 Toyota Highlander SLE AWD towing capacity to be 5,000 lbs. Based on that, you will not have an issue with a 3,850 lb travel trailer with 400 lb tongue weight, but you will want the proper equipment to do so. I recommend starting with the etrailer Trailer Hitch Receiver - Custom Fit - Matte Black Finish - Class III - 2" Item # e98844 rated for up to 900 lbs tongue weight and towing up to 6,000...
view full answer... - How to Determine if 2008 Toyota Highlander is Equipped with Factory Taillight ConverterLuckily, rather than trying to understand the VIN check, the easiest way to determine if your Highlander is equipped with the taillight converter is to get a quick peek at the 10-pin connector it would plug into. The connector is located under the dash, between the emergency brake pedal and the brake pedal, as shown in the provided photo. If there's nothing plugged into the connector, you'd want to use the # HM11141845, as the trailer wiring won't work correctly without a taillight converter....

- Recommended Trailer Hitch for 2017 Toyota Highlander with Full Sized Spare TireFor your 2017 Toyota Highlander that has a full sized spare, I recommend the Draw-Tite Class IV Max Frame Round Tube Receiver Hitch # DT65MR. This hitch is custom-fit for your vehicle and will allow your full size spare tire to remain stowed under the Highlander. I have attached an image that shows the hitch installed on your 2017 Highlander with the spare tire still in place. This Class IV trailer hitch will provide you with a 2 inch receiver opening and a towing capacity of 6,000 pounds,...

- How to Determine 2015 Toyota Highlander Has Factory Taillight Converter for Trailer WiringHere's what you'll want to do to easily determine if your 2015 Toyota Highlander has the factory converter for trailer wiring. Check out the install video link I attached and fast forward to the 4:00 minute mark. This is the portion of the install video for the # C56217 that covers installing the needed fuse to activate the converter box of the kit. If your Highlander already has a fuse in the shows slot you have the converter already and all you'd need is the # 56042 for trailer wiring....

I like the Hopkins because these are the easiest installs. The next thing you will need is the 7-Way RV Upgrade Kit for Trailer Brake Controller Installation # ETBC7L, which will give you...

- Recommended Trailer Hitch and Wiring for 2019 Toyota Highlander XLE HybridThe trailer hitch I highly recommend for your 2019 Toyota Highlander XLE Hybrid is the EcoHitch Trailer Hitch Receiver # 306-X7250 because it offers a concealed crosstube so your Highlander keeps a clean look. I have added a link to a video install of this hitch on a 2019 Highlander as well as a link to the written instructions. For a wiring harness to add a 4-way so you can power your trailer's lights, I recommend the Hopkins Plug-In Simple Vehicle Wiring Harness # HM11141845 if your...

- 4-Pole and 7-Way Wiring Harness for 2015 Toyota HighlanderWe can help you with 4-pole wiring to go along with the Curt hitch # C13200 for your 2015 Toyota Highlander. If your truck has the factory tow package wiring in place (with the under-dash converter) you'll use Curt # 56042 or Hopkins # HM11141825, both of which connect to the vehicle with a square plug as shown in the photo I linked for you. If you do not have the tow package then instead use Tekonsha kit # 118449. Please see the linked video. If you want to have a 7-way type trailer...

- Trailer Wiring Harness for 2018 Toyota Highlander XLEInstalling a 4 pin trailer wiring harness is a plug and play proposition on all models of your generation of Highlander. Since your Highlander doesn't have the trailer package, you'd want to use # 118449 which installs using the two connectors under the cargo floor right at the threshold for the rear hatch. The kit includes the converter assembly, the trailer connector that plugs into the other connector and the fuse that would need to be installed in the fuse box in the engine compartment....
view full answer... - Trailer Hitch and Wiring Kit Recommendation for 2017 Toyota Highlander The most popular trailer hitch we offer for your 2017 Toyota Highlander is the Curt part # C13200 which would fit and work well. I attached an install video for you to check out too. For trailer wiring you'd want the part # HM11141825 since you listed your vehicle as having the converter under the dash and having the tow package. If you didn't have the tow package you'd want the part # 118449 instead. If you wanted to do some towing you might be interested in etrailer ball mount kit...
view full answer... - Troubleshooting Loss Of Trailer Running Light Function On A 2019 Toyota Highlander XLEHey Johnathan, Since you've already checked the fuses and found everything was fine that leads me to believe that the Hopkins Plug-In Simple Wiring Harness # HM11141825 has an internal short. I recommend unplugging it from the factory connector and then turn on your running lights. You can then test the factory connector using a circuit tester # PTW2992 to see if the signal is coming through. If it is then we know the # HM11141825 just needs to be replaced. If the signal isn't coming...
view full answer... - Ground Clearance with Curt 2 Inch Trailer Hitch Installed on a 2014 Toyota HighlanderWhen we installed Curt trailer hitch # C13200 on a 2014 Toyota Highlander we found that from the ground to the top of the receiver opening was 15-3/4 inches. So to the bottom-most part of the hitch that would be approximately 13-1/4 inches. For that to be an issue the driveway would have to be at a fairly severe angle though it is still possible. Based on the height info of 13-1/4 inches you should be able to determine if there will be enough clearance. If you plan on doing some towing...

Most likely it is a blown fuse or missing fuse on the driver's side underneath the steering column, and it is not a super uncommon situation for these fuses to be missing from the manufacturer. This should be a 7.5A fuse labeled "IG1 NO.2"; consult the diagram on the fuse box for the exact location. Check the fuse if there is one and see if it is...

It is a custom fit for 2008 to 2013 Lexus LX 570 models only. For your Highlander, there are only 4 way options available with the tow package.

To get a 7-way on your Highlander start with the # HM11141825 4-way and then use our # ETBC7 kit to convert it to a 7-way. The kit plugs into the already installed 4-way for the lighting funtions and includes all of the wiring needed for the additional functions. I've linked a video from when we installed the # ETBC7 kit on a 2014 Highlander...

No 12 volt wire is need to be ran up to the battery. The 4 way connector will be stowed beneath your vehicle, near the trailer hitch.

The other way to tell is to check and see if there is already a converter on the wiring harness in the rear hatch area. If you check out the attached picture you can get an idea of where...
