Installation
This custom-fit T-One connector plugs into your vehicle's factory tow package wiring harness, which is located behind the driver's-side interior trim panel in your rear cargo area. Once you've plugged in the connector, 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 plug on your automobile and the 4-pole connector itself - to help prevent corrosion.
A ModuLite power module is built into this T-One connector. 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 your trailer. This power module functions as a tail light converter to combine 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.
With a ModuLite, your trailer's lights will be powered without overloading your vehicle's electrical system. Because the module draws power directly from your car's battery and bypasses the electrical routes that are used by a basic wiring harness, there is virtually no draw on your tail light circuits.

Powered ModuLite reduces strain on wiring system.Wish I bought etralier's tow harness earlier. Easy installation. Toyota dealership sold me the wrong one and of course waited too long to return. But use some of the parts from that harness on the one from etrailer(see pics). Would order again from etrailer. Thank you
Pluged into the pre-wired factory tow-package connection. 10amp fuse was sent .. toyota says use 20amp in manual and in fuse box,. used a 15amp fuse,. No drilling factory holes were fine in both the electrical wire run threw hole and hitch installation pre-drilled holes for trailer hitch,.
before ordering check under the hood of your highlander's fuse box to see if it has a tow fuse option/s that tells you if its factory electrical pre-tow plug or not in the back,. look at my photo's of the wireing and hitch,. get the hitch that loops below the muffler,. also it depends on the year of the highlander,.
Receive product in record time. Took longer to get myself in gear. From start to finish, removing trim as per your video, unplugging original harness, installing your product, reinstalling trim, may have taken 20 to 25 minutes. That includes using a rubber body plug to route wiring to a permanant wire mount at the hitch instead of harness out the hatch when needed.
We installed this on my 2006 Highlander Hybrid in about 20 minutes. It took 20 because we are stupid. It really only takes about 10 minutes. #WellDone eTrailer. Both my hitch and harness are from you and are perfect!
Well made, easy install. Both items better than expected. Thanks
Dianna was able to answer all of my questions, especially my concern about the hitch being compatible with a full sized spare tire, which it was. the hitch was installed and in use with a bike rack within hours of delivery. Just what we needed.
The item was well packed when arrived, was very easy to install and set up, video on the page was very helpful and you can see that not only is a good quality but good looking too.
Instructions provided with adapter are good. My 04 Highlander without tow package had the connector under rear, driver-side cargo tray. Lift the cargo floor, remove the tire-change-tool tray, remove the two plastic nuts on the bottom of the left-side tub, and lift it out. Also under that storage tub is an unused 6mm threaded hole in the body to be used for the ground. Put a fuse in the correct spot of engine compartment fuse block (mine was empty) and good to go. See underside of fuse block lid for tow adapter fuse placement.

Used 20 times this summer with no issues. I would buy again.
Ordering with etrailer was super helpful. I was adding a hitch to an older model highlander and e trailer staff were awesome at getting back to me by phone and emailing links to make sure I got exactly what I needed. Shipment to Alberta Canada was prompt. Would definitely recommend ordering from e trailer.
I was very pleased with the perfect match and plug-and-play aspects of this connector.
The unit which I replaced had fuses in each of the leads for lights (running and left/right function). Since the leads in your unit were not similarly fused, which seemed like a good idea, I just cut off the wires heading to the trailer plug from the black box, and retained my original wiring with fuses from that point onward.

It must be functioning perfectly, because I havent given it a second thought. I like functioning perfectly, and have high expectations it will contiue to do so.
worked great - had uhaul originally do wiring - it was a mess. they had run a wire under car to battery when power was already in back with factory installed harness. The wiring harness I bought at etrailer fit perfect and was installed by me in 10 minutes or less. and was $100 dollars cheeper than uhaul. Thanks !

It has worked perfect- no complaints.
Connected and worked with no problem. Was not sure if my highlande highbrid had the tow package but after some research i discovered that all highlander hybrids come with a tow package even if it does not have the trailer hitch receiver

What year is your HL highbred?Where did you find the info that all HL highbreds have the tow package?
Anthony took me through everything I needed to fix an inoperative unit that had been previously installed. The etrailer video showed me everything else I needed. In hind sight I should have gotten the 4/7 pin unit since when I picked up my rental it was a 7 pin. I picked up a 7 adapter on site and was on the road. Thanks Anthony!

Works great, been dragging our trailer for 5 months.
I am no mechanic, but the hitch wiring was easy to install on our 07 Highlander. Find an installation video on-line.
Works without a hitch!

We have not had any issues a year later.
Super easy installation both receiver and harness.
Ordered this Toyota highlander trailer tow harness. I've been it using for over a year. It came in a timely manner, installed easily, and performs well. It is well thought out, in that it installs easily, did not have to get under the car at all to install. No special tools required. The trailer led is long enough to directly connect to either of my two trailers. (a small camper pop up, and a small 4x8 utility trailer. The led just lays in the rear tool compartment out of the way when not in use. The led simply goes under the rear hatch door when in use.
My first purchase from etrailer and I couldn't be more pleased. The wiring kit for my Highlander ( 06) went together without a hitch, and best of all, worked perfectly. I was lucky enough to have AngelaK on the other end and she was most helpful with my order. I hung up feeling good about the whole thing. I've already recommended etrailer to my son who was having trouble with the 4way on his Tacoma.
After troubleshooting why my trailer lights were not working, I discovered that the power module on my 2007 Toyota Highlander was bad. I searched the net and found etrailer.com, found a replacement wiring harness and ordered it. The harness arrived quicker than I expected and I was able to remove the old harness and replace with the new with no problems. The new harness works great! I'm back on the road with my bass boat lookin' for that lunker.
Very nice products - loved the fabrication and powder-coating of the hitch. Shipped promptly, good on-line tracking information. Good prices. Good instructions. It only took about an hour to install the hitch and wiring harness.
Only possible improvements might be to omit the purchase order label stuck to the hitch. It was tough to get off. The installation took a little longer because I had to run to the parts store as part of the installation was to purchase three plastic one-time fasteners that Toyota uses to cover the fuse panel.
I'm a happy customer!

At the good,old age of 73, I took my Highlander apart and found the auxiliary tail light wiring. I called e-trailer and ordered the e-wiring harness for the118248 factory tow package.
The clerk was knowledgeable, polite and instead of 10 days the wiring harness arrived in just 4 days. I popped the plug in, fixed the ground wire and placed the fuse which was enclosed.
It took longer to put the car back together.
Sure, simple, easy.
I was sitting on the front porch waiting for the package to be delivered on the scheduled delivery date. An hour later it was installed and and that included time spent covering the exposed portion of the wiring with protective plastic conduit. Looked at the installation video before I purchased and watched it one more time before beginning the removal and replacement. The etrailer product is Identical to the faulty factory harness (bad converter?) in my 2005 Highlander (except the new one works perfectly). I couldn't have had a better experience.
Great product. OEM fit. the install video was spot on. Start to finish, about 45 minutes. I reused the stock wire conduit for protection.
My only suggestion to make this an excellent product is to offer it with connectors on the trailer harness side. So that when the control box goes out(probably will) I just have to replace it and not run the harness again.
Excellent plug and play adapter. Took a second to find the right wiring harness to plug into but then it went great! works seamlessly and stows cleanly away in the cargo area hidden storage. awesome product.
The product was an exceptional value, shipped & recieved 5 days of order ( I thought that was a great turnaround time). The product fit as discribed on the installation video. I would recommend this site to anyone interested in their tow package wiring harness. The installation demo video was the number 1 selling point. It was a very detailed demo that allowed me to do the installation without the dealers help ( they wanted $70 for some part, but couldn't tell me how to install it or where it should plug in).
