Installation of Tekonsha T-One Connector

This custom-fit T-One connector plugs into your vehicle's wiring harness, which is located at the rear of your vehicle. Once you've plugged in the T-connector, run the body harness up to your car battery and connect the wires per the included instructions.


Once installation is complete, the 7-way connector will be stowed beneath your vehicle, near the trailer hitch. A mounting bracket (sold separately) is recommended to keep the connector secure.


It is recommended that you use a small amount of grease on all electrical connections - the plugs on your automobile and the 7-pole connector itself - to help prevent corrosion.


ModuLite Powered Tail Light Converter

A ModuLite power module is built into this T-One connector. Because most trailers run on a 2-wire system - wherein the brake and turn signals are carried on one wire - the separate brake and turn signals from your vehicle's 3-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.


Installation of Tekonsha Brake Controller Adapter

This adapter plugs into the 4-pin connector on your vehicle's built-in brake control wiring harness. The harness is located near the steering column, through a grommet in the engine compartment.


This adapter requires no hardwiring. It is designed to plug directly into your electric brake controller for the simplest installation possible. Because there are no wires to connect, installation is not permanent. You can unplug and remove your brake controller at any time and securely stow it away.

Review from a similar T-One in Custom Fit Vehicle Wiring


Product quality very high, delivery very fast, shipping container (cardboard box) was not strong enough to support handling/shipment, box bottom was ruptured with hitch assembly hanging out, box should be supported stronger, no parts missing, hitch was scratched up somebut, nothing that a little black paint didn't fix. I installed the wiring harness connections and fuse box on the external side of the vehicle to eliminate having to take apart the internal sheet metal panels and providing easy access to the fuse in the event of fuse failure, this eliminates the necessity of interior Panel removal to change a fuse. Easy installation, product has great great design features ,great customer service with prompt delivery. Just ordered the bracket (#18140) to secure the 4 prong plug to the hitch neatly and secure to eliminate the loose plug. (not shown in photos (Bracket in transit),

Review from a similar T-One in Custom Fit Vehicle Wiring


I purchased this for my 2013 Honda Pilot EX-L. I have not used the wiring harness yet, but the installation was extremely easy and quick. The instructions were very straightforward, and I was able to install everything within 30 minutes. Everything you need is inside the package except some bolts/nuts to mount the connector. I decided to cut out a hole and drill some holes for bolts. I opted for some black ones to match the colors. I'm extremely happy with this product and etrailer's fast and reliable service.

Just installed Draw Tight hitch, wire assembly along with the brackets for a nice look. Everything went smooth with installation and it has a nice clean look as the hitch is well hidden. This is going to work for our bike rack and the cargo carrier I am now going to by. Now I can also get a small utility trailer to pull and haul stuff. I strongly recommend etrailer for all your needs as they communicated with me the whole way through and readily replaced a lock unit that somehow came without the key. Customer service is top notch.

Review from a similar T-One in Custom Fit Vehicle Wiring


This is a perfectly tailored product for the do-it-yourselfer who with a little help adds a nice hitch to his vehicle. Getting an older vehicle's OEM installed weld nuts clean takes most of the time followed by installing the two washers and nuts in the fascia area. That part needs patience as the work area is limited. The Curt LED 4-Way Flat Connector (Vehicle End) Tester makes it very simple to verify the Tow Package - 4-Pole Flat Trailer Connector that is a snap to install to the vehicles pre-existing harness. One point to pay attention to in the instructional video is when pulling the square washer and bolt through the channel. They must slide in single file as shown. If you try to pull with the bolt through the washer it will get stuck and you will need to fish it out. So bottom line. Great product. Great support. Steve Stewart

Everything from the hitch to the wiring still works perfectly. Very pleased with the results

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

Plug & play for 2020 Kia Sorento. Dinged a star because the trailer connector does not fit the extra bracket well. It does not appear to have been designed for a bracket mount. I had to force fit and secure in place with a zip tie.

Review from a similar T-One in Custom Fit Vehicle Wiring


Good product and great service from etrailer! !!!Important note: 2012 Nissan Xterra (depending on what factory it was built) has the 12v power and brake wire REVERSED on the factory installed harness. Meaning when you plug in your trailer, there will be constant power to the brakes on no power to the charge line. If this happens to you like it did to me, you need a tester and a couple butt connectors to make the switch at the 7 pin connector. Also note, these plugs use the trailer for the ground so you're tester wont read if the trailer is not plugged in and you have to hold one of the tester ends to metal on the trailer.


Comments
Thank you for your review. This is a common issue on the Nissans. I have attached a very helpful article that explains the issue and how to fix it.

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.

FITS the new 2020 HIGHLANDER! There is a new connector with the 2020 Highlander redesign under the driver side rear bumper. This cable plugs directly into the Highlander connector. See photo. There is no need to route or run wires for the trailer wiring. You will also need a converter to provide the correct signals to this cable. I recommend using the Toyota Plug-n-play converter part number: PT725-48200. It’s around $60 online. Be aware it is installed behind a panel located next to the driver’s side second row seat. Toyota completely changed the vehicle wiring for the 2020 model year. I also recommend the CURT C99FR hitch. Fits perfectly, easy to install and hides behind the bumper.

This kit worked great. It took about an hour to install on my 2005 Xterra. The process was just like the video on etrailer.com. The only difference was that I mounted the bracket directly to my bumper instead of the hitch.

Jesse at eTrailer help me with configuring my 2009 Honda Pilot to be able to pull legal loads. I had previously installed their 4 pin connector but I want to be able to use trailers with brakes to full extent. I added a Redarc brake controller in a convenient location. Easy to replace the current harness with the 7 way connector. A little more work to pull panels to locate the Redarc control head exactly where i wanted it, but no biggie. As always, great customer service and a great product. Thanks Jesse and all at eTrailer.

Plug and play! This trailer power cable plugged directly into my factory Cadillac SRX wire harness. No wire cutting and splicing, absolutely the easiest installation I could imagine. Highly recommended for anyone who can use it. See photos showing the purchased product and where it plugged into the factory wiring harness.

Excellent prompt personal service. Website made it easy to select the correct components for my particular SUV. Was kept informed throughout the delivery process, I knew exactly where my package was and when it would arrive. Would certainly recommend using etrailer - a great and professional service. Fitting the wiring was a breeze, once the appropriate socket for the trailer module was located (hiding behind the rear R/H side fascia panel)

I ordered and received a trailer hitch and wiring kit for my 2015 RX350 and also received a very informative video with it. It fit great and is almost invisible and no drilling was necessary. The only issue I had was I was supposed to reuse 2 of the bolts to rehang the exhaust but my bolts were tapered on the end and wouldn't fit so I had to use some generic bolts. But it's still a great product.

Review from a similar T-One in Custom Fit Vehicle Wiring


Excellent product. Delivered fast and painless. Fits perfectly. Please note the factory will usually leave the required fuses and relays uninstalled even if you have the Tow Package. My 2009 Escape needed 2 mini fuses (1 - 15A and 1 - 20A) and 3 relays to energize the harness. These were available from the auto parts store. Refer to the photos. Photos #1&2- The two pages from the owner's manual that describes the sizes and locations of the fuses and relays. Photo #3- A photo of the fuse box located under the hood (front -left) with the fuses and relays installed. Photo #4- The installed connector.

Review from a similar T-One in Custom Fit Vehicle Wiring


Kia dealer installed the original 4 way flat trailer wiring 2 years ago. The tester showed 2 dim lights before I ever used it. Disregarded the dim lights and added the ignition 12V and brakes control wires to a 7 way Bargman connector. I had running lights without anything on which worked only 2 times. Then no right brake or signal flash. Removed the factory Kia 4 way flat and observed no fuse! THEN I ordered the eTrailer equivalent WITH a 15 amp fuse. The tester looked good with no lights initially then the brake, running and turn lights tested fine. Hooked up and tested fine also. Happy customer!

Review from a similar T-One in Custom Fit Vehicle Wiring


I recently purchased a pontoon boat that had hydraulic brakes. First time out had to back up the trailer uphill, not a good experience with the brakes locking up. My F150 has only factory 4 pin trailer connections so I looked for a 5 pin option with reverse brake override power. Etrailer is my first stop on trailer parts. The wiring harness and relay in the kit fit perfectly, but needed a large adjustable pliers to snap to the connectors together on one connector. Had to fabricate a bracket as the overall length of the 7 pin receptacle and connector means it had to be set 2” towards the bumper to clear the hitch assembly (also e-trailer). A few tie wraps later everything was done and tested. Instructions were good, but didn’t need to drop the spare to get at everything. Would recommend.

Simple addition to my 2008 Ford Escape to extend the factory trailer wiring harness from behind the bumper down to my new Drawtite trailer hitch reciever. I was fortunate enough to have the wire harness already installed including the fuses and relays. Might have taken 5 minutes to install and came with 2 zip ties to secure the extra wire. No tools needed.

    So since you have the factory tow package on your 2016 Hyundai Santa Fe Sport the first thing you need is the 7-way kit part # TK24FR that you referenced. This kit comes with wiring for a brake controller install so to install the Redarc Tow Pro Elite part # 331-EBRH-ACCV2 you'd just use the included wiring of the controller to splice then to the brake controller wiring and you'd have a really great and out of the way proportional brake controller.

    Yes, your 2019 Kia Sedona without the factory tow package is still compatible with the Tekonsha OEM Replacement Vehicle Wiring Harness with Brake Controller Adapter # TK24FR. According to the manufacturer, Tekonsha, this is compatible with all models of Kia Sedona and will plug into the tow package port which will be on your vehicle.

I'll start out by saying that the Tekonsha # TK24FR you were looking at only has a 7 way plug, so it's not going to be the correct part for this application.
