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 plug on your automobile and the 4-pole connector itself - to help prevent corrosion.

After balking at the cost to have an auto-shop add a trailer to our Toyota Highlander, we found etrailer.com and decided to take a chance. The "how to" videos factored considerably in our decision to buy ... they made it look so easy! And surprise! It really -WAS- that easy. We used standard block-type ramps (the kind you can buy for $40 ) to get the SUV up off the ground high enough to get underneath to do the work. Everything came off as easy as it was showed in the videos. Other than the fact this bar is a heavy so we had our teen daughter help hold it steady while we bolted it into place (i.e., get help for when you go to lift it), it went super smooth. Thanks for saving us $280 over the cost the car dealer quoted us! P.S. - be sure to watch the linked videos so you get the right trailer lighting attachment and ball hitch for your new hitch.
Comments
We are very happy with our trailer hitch, and all the accoutrements that we purchased with it. Your videos were enormously helpful, the hitch went on easily with a bit of help from our teenage daughter to lift it up into place, and we recommend your business to friends when they express an interest in getting a camper.

This wiring harness was a huge time-saver over wiring things manually like we did for our last trailer hitch a long-long-long time ago! If you're not sure what to buy, watch the videos they have to make sure you get the correct one for your needs. We saved a HUGE amount of money over what the auto dealer quoted us for the exact same thing, and as a bonus, the how-to videos made it really easy to attach it ourselves. Yes, it really -is- that easy.

Was easy to install. The original was broken from someone hitting it. The replacement is not mounted on the outside but left in the storage space until needed.
Comments
Still working. I installed it and store in the area under the back mat. I believe thats the best because its not exposed to the weather. Id buy it again if needed as I saved a ton of $$ by doing it myself.

2012 highlander had factory tow package. This harness mounted in fine to the factory plug in the back but there was no power at the connector. After some research I found that I still needed to go to the dealer and purchase a $100 towing converter that plugs in under the dash on the left side.
Comments
It sounds like your 2012 Toyota Highlander didnt come with the factory tow package and that you would have needed part # C56217
Curt T-Connector Vehicle Wiring Harness with 4-Pole Flat Trailer Connector
$41.53. It includes the additional wiring component that installs under the dash to complete towing circuit.

Great ordering and quick delivery. Product was just as described and super easy to install. Just a little disapoited in the wireharness that was available as it does not have a bracket to clamp to the hitch and will need to be replpaced. Make sure to order the correct one.

***READ THIS*** Great product, easy install *BUT* This might help someone else. I called the dealer and found that my 2012 Toyota Highlander has the " V-6 Towing Prep Package" I had assumed that was the factory towing package, I was wrong. Save yourself the trouble and physically look under the dash for the white connector as well, if nothing (no converter) is plugged into it, you will need the other wiring kit with the converter. [one of etrailer.com videos] clearly shows the connector I'm talking about on a 2012 Highlander I have now ordered the correct part. I am still very happy doing business with etrailer.com Thanks!

- Troubleshooting a Trailer Wiring Harness # 56042 Install on a 2014 Toyota HighlanderThe 4 pin connector used to install the # 56042 can be in a few locations which does make the install a little more interesting. I am glad you were able to find it. I would verify that you put the fuse in the correct location. If that doesn't fix the problem I would verify that the connector of the # 56042 is making solid connection with you tow vehicle and that the fuse didn't blow while in the wrong slot. I attached an install video that shows a very similar product being installed...

view full answer... - Vehicle Towing Capacity and Trailer Weight CompatibilityThe GVWR spec for a trailer, its gross vehicle weight rating, is the most it can ever weigh. This 3800-lb figure for your Coleman travel trailer includes the trailer's own dry weight of 2715-lbs plus the weight of water, propane, food, sporting gear -everything that goes in the trailer. You do NOT need to add the trailer's tongue weight (TW) to this figure. If you subtract the dry weight of 2715-lbs from the gross weight of 3800-lbs you get the maximum total cargo weight, 1085-lbs.

- Trailer Wiring Harness Recommendation 2012 Toyota Highlander with VIN That Indicates Tow PackageYes, what you found by giving your VIN to a Toyota dealer is the relevant info for picking out trailer wiring. So that means the Curt trailer wiring kit part # 56042 would be all that you'd need to have a 4-way. This easily plugs into a port at the rear of your vehicle and you'd be set. I attached an install video for this kit for you to check out as well.

view full answer... - How to Determine if 2019 Toyota Highlander Has Factory Tow Package for Wiring HarnessThere are a couple ways you can determine whether or not your 2019 Toyota Highlander is equipped with the factory tow package. The first method consists of simply looking for the plug(s) that the appropriate trailer harness would connect to; either the Tekonsha T-One # 118449 if you don't have the tow package or the Curt T-Connector # 56042 if you do. With regards to wiring the tow package essentially provides the needed converter box, so it's not included/needed with the Curt harness....

- 4-Pole Trailer Wiring Harness for 2015 Toyota HighlanderThe best way to confirm exactly what factory equipment has been installed in your vehicle is to contact your local dealership with the vehicle VIN. This allows the dealer to look up all of the production details for that specific vehicle. This is the best way to go since exactly what individual items constitute a "trailer towing package" are NOT standardized and could vary considerably. Some auto makers' tow package may mean a hitch only; or it could mean a hitch and wiring; or a hitch...
view full answer... - Recommended Wiring Harness for 2017 Toyota HighlanderIf your 2017 Toyota Highlander came with the factory tow package, you will have a converter under the dash. If the vehicle came with a factory 7-Way connector and a trailer hitch, it likely has the tow package. If it did not come with a 7-Way and trailer hitch, then most likely it does not have the tow package or the converter under the dash. The most accurate way to determine what your Highlander came equipped with is to simply visit your local Toyota dealer with your VIN. They will...
view full answer... - Trailer Wiring Solution for 2015 Toyota Highlander without Factory WiringSounds like your vehicle is still missing the middle section of wiring for trailer wiring.

Since your vehicle has the towing package you most likely have trailer wiring already, but in case you do not we have the Curt 4-way part # 56042 which is a confirmed fit. Since you wanted to do some towing you might be interested in etrailer ball mount kit # 989900. It comes with 2 ball mounts; one with a 3/4 inch rise or 2 inch...

- Why Would Trailer Wiring Harness in 2008 Toyota Highlander Stop WorkingIf you had the part # 118449 installed in your 2008 Toyota Highlander that would indicate that you do not have the factory tow package. This harness comes with a converter box built into it so I am not sure how you would have actually had this harness installed if you don't have a converter box. If instead what you have looks more like the part # 56042 then you do not have the # 118449 installed. The part # 118449 has an inline fuse on it for the power wire that connects right the port...

To convert to a 5-way you would need # 47515. For your 2008 the same # 56042 is a confirmed fit as well.
view full answer... - Recommended Trailer Wiring For 2016 Toyota HighlanderOn your 2016 Toyota Highlander, there are two possibilities from the factory regarding wiring. One possibility is that your vehicle came with the tow package and has all the trailer wiring you need already in place. The other possibility is that there are wires run for quick connects and you just need to add the wiring and the converter box. If you need the wiring and converter, I recommend the Tekonsha T-One Vehicle Wiring Harness with 4-Pole Flat Trailer Connector # 118449. This harness...
