Installation on 2014 and 2015 Toyota Highlander
This custom-fit T-connector plugs into your vehicle's wiring harness. The connection points for the 4-way tow harness and the converter are located underneath the spare tire compartment. Once you've plugged in the converter, locate the "towing fuse" position in your fuse box and insert the included 10-amp fuse.
Installation on 2013 and Earlier Toyota Highlander
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 driver's-side interior trim panel in your rear cargo area. The converter plugs into the factory wiring harness beneath your dash, on the driver's side. Once you've plugged in the converter, 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.
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
A tail light converter is built into this T-connector. This converter is a 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.

In addition to the wiring kit, I also purchased the tow bar attachment for my Toyota Highlander. I was thrilled with how easy it was to install and the step by step video instructions on your website was exactly what I needed. Everything works perfectly and I was able to pull about 5 tons of stone in one haul which made me very happy. The trailer hitch and wiring has already paid for itself multiple times over in what I would have spent on delivery fees for my patio projects.
Thank you for a great product and a fantastic user experience.
by: William 06/05/2023
The product was exactly what I needed. However shipping through usps stinks. They were days late and when it came I met the postman who said he didn’t have the package then found it at the bottom of his bag. I guess I might never have seen it.

Product shipped in very Good condition. Installation instructions were very good. Saw the supporting online installations were excellent too. Thank yo

The wiring harness was easy to install. Clear precise written directions were given (which I do read). The trailer lights work every time I tow something. Thank you, thank you!!

The hitch receiver is working well primarily as a bicycle carrier. It has pulled a light duty trailer well.

Not very good instructions included but not too difficult for hubby to install. [online video] was very helpful!

No problem with the wiring harness

I was nervous about ordering and installing this kit myself, but it really was incredibly easy. I didn't have to do any splicing, it really was just plug and play.

Great products! The shop had everything it needed to setup my 2017 Highlander up for towing a camper trailer.

Very easy installation on my Highlander. Easiest install I have ever done. Very heavy duty hitch, at a great price.

I’m loving this trailer hitch receiver. My 8-yr old some helped me do a self-install on my 2015 Toyota Highlander. The instructions on the retailer website were fantastic, and with a little patience and the right tools, we had no problem installing this ourselves - savings hundreds of dollars!

The hitch and 4 flat wiring kit were great and everything went together easily, I would say it took approx. 40 minutes to install everything including the hitch and the wiring - very easy and straight forward. The videos from e-tailer were very helpful. We used the hitch on our Highlander to pull our boat to the lake this weekend. Everything worked as it should with no issues. I give it 5 stars.

Your shipping company SUCKS!!!! Your service and product was Fantastic. I would really rethink your shipping company. Look at attached photo. My harness was soaked.

Wiring took 5 minutes to install. Only complaint is with a 2015 highlander you need to buy the “WITHOUT TRAILERING PACKAGE” option even if you have the XLE or above with tow prep package

No problems, good product

A little disappointed...did not come with everything. It was missing a fuse, zip ties and the grease...wish the product would say that it wasn't coming with these items. Once I went and got my own fuse I got it to work.

Super easy and convenient to install. After removing certain panels in truck, you literally just plug connectors together, install the fuse at front fuse box and you are good to go.

- Recommended Hitch, Wiring Harness, and Brake Controller for a 2013 Toyota Highlander I would be happy to help you set up your 2013 Toyota Highlander for towing. I will start by confirming that the etrailer Trailer Hitch Receiver item # e98858 does fit your Highlander. Since you do not have any vehicle connectors at the rear of your Highlander you will need both item # HM11141845 and item # ETBC7 to add a 7-way connector. The Tekonsha Prodigy P3 Trailer Brake Controller item # 90195 is one of our most popular brake controllers and is highly recommended. I have linked a...

- How to Route 4-Way Connector Underneath 2011 Toyota HighlanderWhen you install the 4-Way, like the preferred T-One Vehicle Wiring Harness # 118449 over the Hopkins # HM11141845, on your 2011 Toyota Highlander you want to look for a plug at the bottom of your cargo area. If you slit this open you should be able to feed the 4-Way underneath your vehicle and then seal the plug back up using Gasket Maker # LT37467. Then you just have to plug in the 4-Way to the back of the Hopkins # 37185 adapter and secure it to you hitch receiver using the No-Drill...
view full answer... - 2019 Toyota Highlander Wiring Harness Installation TipsThis Hopkins wiring harness does fit your 2019 Toyota Highlander. Since the location of the factory wiring is located inside the car and not under/behind the bumper, you will likely be limited to the current location of the wiring. That being said, the hitch you are looking at # E98844 would be a good choice for your vehicle. The one suggestion I will make is that if you reference the picture attached to this question, there is a screen shot of a spot in the install video that shows a...

- 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...

- No Lights On 2017 Toyota Highlander After Installing Hopkins Plug-In Wiring Harness for Factory TowI have personally seen this issue a lot. The good news is that it's a simple fix, you need the Hopkins Plug-In Simple Vehicle Wiring Harness with 4-Pole Flat Trailer Connector part # HM11141845 which has the converter harness whereas the Hopkins Plug-In Simple Wiring Harness part # HM11141825 you have now only has the trailer connector harness. I know what your next question is going to be as well, can you purchase just the converter harness but unfortunately this is not offered by the...
view full answer... - Will Hopkins Wiring Harness for 2017 Toyota Highlander Work With or Without Tow PackageIn my experience, most Toyota Highlander's don't have the factory tow package and need both the trailer connector and converter like what comes with the Hopkins Plug-In Simple Vehicle Wiring Harness with 4-Pole Flat Trailer Connector part # HM11141845. If you did in fact have the factory tow package, you would simply only use the trailer connector as there would already be a harness plugged into the spot for the converter. If you want, you can use the install instructions for this product...

Instead you will use one of the two universal harnesses available. For the easiest installation the ZCI Circuit Protected Vehicle Wiring Harness part # 119250KIT is a great choice. It will clip around the wires to receive signal to operate the lights. This eliminates the need to cut or splice any of your factory...
view full answer... - Recommended Hitch, Brake Controller, and Wiring Harness for a 2013 Toyota Highlander I would be happy to make some suggestions for you. I will start with a hitch. I recommend the Draw-Tite Max-E-Loader Trailer Hitch Receiver item # 75726. This hitch is custom fit and bolts to your 2013 Toyota Highlander with included hardware. This hitch is compatible with weight distribution systems. I have linked an installation video below. There isn't a harness available that will provide you with the needed 7-way connector so you will need two separate ones. For a 4-way wiring harness...

When you are towing a trailer it is the sum of the vehicle weight (which includes passengers, cargo, and any other optional equipment installed on the vehicle) and the Tongue Weight (TW). If your fully loaded and ready-to-go trailer only weighs 3,400 lbs then you have 2,950 lbs to work with. You will want to double check your weights and your manual as well just to make sure and for any specific instructions. If...
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....

- Purpose of Grease Packet Included with Hopkins Plug-In Simple Vehicle Wiring Harness HM11141845No, the Hopkins Plug-In Simple Vehicle Wiring Harness with 4-Pole Flat Trailer Connector # HM11141845 includes a taillight converter that will combine your separate stop and turn signals into the single-wire format used on trailers. Your Highlander does not need to have one too. The small packet included in the kit contains dielectric grease like # 11755. This grease is to be applied to all connectors in the kit at the time of installation. The grease does not conduct electricity but it...

It is a proportional controller with an LCD display, storable settings, 3 boost levels, runs continuous diagnostics, and is transferable between vehicles.

The good news is we do have a EcoHitch for your 2018 Toyota Highlander. The EcoHitch Hidden Trailer Hitch Receiver # 306-X7397 that you referenced is for a 2018-2021 Audi Q5 which mounts differently and doesn't even share the same chassis as your Highlander. The EcoHitch Hidden Trailer Hitch Receiver # 306-X7250 will fit your Highlander. This hitch is rated for 750lbs of tongue weight and 5,000lbs or trailer weight,...

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 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...
view full answer... - How to Determine if a 2019 Toyota Highlander Has a Tow PackageBasically what it boils down to is that if you have the tow package you'll already have a 4-Way trailer wiring connector on your 2019 Toyota Highlander so if you don't already have one odds are you need a wiring kit with the converter like the Curt # C56217, Tekonsha # 118449, or Hopkins # HM11141845. 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...

I have a hitch for you but Draw-Tite's parent company is being bought out (3/07/2023) so their inventory is low or nonexistent which explains why you can't find that hitch. Instead you will want the etrailer Hitch item # e98858. This hitch is custom fit and bolts to your 2012 Highlander Platinum with included hardware.

This custom-fit harness will install by connecting directly to the built-in ports located in the rear cargo area on the driver's side of your vehicle.

view full answer... - Trailer Hitch, Wiring Harness and Mounting Bracket for 2018 Toyota HighlanderThe Curt # C13200 trailer hitch is a confirmed fit for your 2018 Toyota Highlander and if you are looking at Adapter # 30717 I assume you already have a 4-way harness such as # 56042 or # HM11141845. To attach adapter # 30717 you simply need to use the No-Drill Bracket # C57202 along with Mounting Bracket for 7-Way # 18138. You would attach the no-drill bracket to the hitch and screw the two brackets together. I've added links to video reviews of these parts for you to take a look at.
view full answer... - Troubleshooting Hopkins 4-Way Wiring Harness on 2019 Toyota HighlanderSince you have already established that the fuse is fine and power is running to the connection for the harness there is not much else that can be done. I suggest double checking all of the connections to make sure they are secure. I would unplug each one and plug it back in to make sure they are fully seated. If that does not solve the problem, it is more than likely a bad wiring harness. If you are planning to replace it, I recommend the Tekonsha T-One Vehicle Wiring Harness # 118449...
