Installation

This custom-fit T-One connector plugs into your vehicle's wiring harness, which is located behind the driver's-side and passenger's-side tail lights. You will have to remove the tail light assemblies to access this harness.


T-One Connection Location Points Behind Tail Lights

Once you've plugged in the T-connector, run the hot lead up to your car battery. Connect the lead to the included fuse holder, and then connect the fuse holder to the positive terminal on your battery and insert the provided fuse.


Once installation is complete, the 4-way flat 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 4-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 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.

Video Transcript for Tekonsha Custom Fit Vehicle Wiring - Trailer Hitch Wiring - 118685 Review

Today we're going to take a look at the T-One Vehicle Wiring Harness with the four-way flat trailer connector. Now this is a custom-fit part. It is designed to fit the 2016 and newer Toyota Tacoma's, and the 2016 and newer Honda Accord Coupes. On any custom fit part, what I always recommend to do is go to our website, use our fit guide, put in your year and model vehicle, and it will show if this will work on your application. Now this part will provide a four-way flat trailer connector to back your vehicle to power your trailer's signal lights. It is compatible with 5-pull, 6-pull, and 7-pull adapters that we do sell separately. This does connect very quickly and easily.

Basically, all you have to do is locate your connection point behind the tail light at the rear of the vehicle. What you will do is connect your T-connectors, plug these in on the driver's side and these in on the passenger's side, and then you'll ground your white wire, and then all you have to do is run this black wire, which is a power wire, to the front of your vehicle and connect to the battery to power the converter. It does include this modulite power converter, and this is to ensure that your vehicle's wiring will match that of your trailer. This is a power module, that's why you'll connect it to the battery. That's to avoid overloading your vehicle's electrical system. The wire that comes out the back that your four-way is on is 16-gauge bonded wire, and the neat feature is the four-way has this integrated dust cap, so when you're not plugged in you can just put it over there to protect those terminals from any damage or from the elements. It does come with everything shown here on the table.

I'm going to show you how all these parts connect here in a minute. I do want to give you the maximum amperage on this harness, the stop and turn light circuits is 5 amps per circuit and the taillight circuit is 7.5 amps. Basically what you'll do is go to the rear of your vehicle, and like I mentioned, go to behind the taillights at the rear and you'll start on the driver's side and take this T-connector that has the yellow and brown wire in it. This is for the driver's side. You'll unplug the harness from your taillights, and then these connectors will match the harness and the taillights.

So you'll plug this in on the driver's side, and what you'll want to do is go to the passenger's side and this longer length of wire, the green and red wire, this will go to the passenger's side, and you'll have two connectors over there. Again, you'll go behind the taillights, match these up to the harness and the taillights, plug them in, and then you can run this bonded wire out the back, and basically you'll have two wires left: The white wire with the eyelet on it, that will need to be grounded. So you'll want to find the nearby ground. If not, they do include a grounding screw that you can use and make your own ground. Then the last wire is the black wire which is the power wire that needs to go to the front of the vehicle to connect to the battery. So what you'll do is they'll give you this extra length of wire to run it up to the front, and you'll use one of the butt connectors to put on here and then make your connection on this. Run this wire up to the front, you can use any of the cable ties to take up any slack from the wiring.

Once you get to the front, the other end you'll want to connect to the battery, but before, you don't want to connect this directly to the battery, you'll want to run it through this end line fuse holder. So you will take the other butt connector, connect it to one side of the fuse holder, and then the other side of the fuse holder you will put this eyelet on and connect that to the battery. Then what you will want to do is pop this fuse holder open and it comes with a 15 amp included fuse. Put that in the fuse holder, push it in, put your cap back on, and be all ready to go. Now they do give you a nice set of detailed instructions that will describe the connections and even show pictures. And they do also have this piece of double-faced tape that you do want to attach this converter box down so it doesn't bounce around. So you can use the double-faced tape or you can use one of the cable ties to attach that down. That should do it for the review on the T-One Vehicle Wiring Harness with the Four-Way Flat Trailer Connector.

Installation wasn’t very difficult, it seems well constructed, and works great. I managed to install on a 2019 Tacoma without lifting the vehicle. The trickiest part was routing the line from tail light to battery, but the videos helped a lot. I wish I had mounted the control box a bit lower in the tail light box, as the wire between tail lights doesn’t have a lot of excess length. My first try routing that line didn’t quite reach, but I found a more direct path on the second try. Be careful to avoid any rub points against metal edges when routing wires. 728241

The product worked great except for the coloring on the (4) wire trailer connection. I wired this to a plug in 7 pin and 4 pin connector and ran into problems with wire color changes on the 7 pin plug. Everything worked great and I place this in protective wire wrap and you cannot see a difference or even notice that this was installed. 726451

Having the wire harness was a definite must in making the installation of the trailer light hook up. It was as easy as the video said. Unplug and plug in. The most difficult part of the process was running the power wire to the battery. Over all I’m satisfied to the highest level with this product. 662447

would not buy from anyone else these guys are great just try to go to a trailer hitch shop and see how you get treated then try etrailer and see the difference you order you receive very fast and you install your self or simply ask a good mechanic shop to install it if you are not familiar with wires etc and in addition etrailer will guide you thru the process over the phone or online never had a problem out of my many jeep projects nor trucks and I am only a house painter who hates assembling stuff my current hitch and huge wire assembly was installed by a tire co in 30 minutes like factory for $100 hitch shop wanted $375 and they would`nt do it unless they welded it h*ll no on a $ 60.000 truck it bolts on perfectly tx again george 332794

I ordered this along with a Draw-Tite receiver hitch for a 2016 Tacoma SR 2.5L so that I could occasionally pull a small utility trailer. No factory trailer attachment options were available from the factory so this was the next best thing. Etrailer had videos out regarding the hitches and the trailer wiring options for the Tacoma before I ordered the vehicle which was very helpful. After I had the vehicle for a year or so I finally ordered the hitch and trailer wiring. The products shipped quickly and arrived promptly. The installation instructions were clear. You will need to run a 12v hot lead to your battery so it will take some time to install but it's pretty simple. The kit includes some wire ties but you will need more to do a tidy job. I also purchased some plastic wiring loom/conduit locally for better protection. I mounted the control module in a different location than what the etrailer video shows. I was able to mount it in the driver side taillight well directly behind the light assembly. It was tight but I thought the location offered better protection. After installation I decided that I didn't like the trailer wiring plug hanging under the vehicle so I found the Hopkins 41144 vehicle wiring kit fit in the bumper like from the factory. I simply bought a spare 4 prong trailer plug and with some crimp on connectors attached it to the Hopkins 4114. Now the truck looks factory and the trailer wiring is better protected. 512316

I signed up with you for snail mail, the least expensive (ground delivery) of my package and it turned out to be a huge mistake. As it turned out, I obtained the services of an experienced mechanic much earlier than I thought, and we just had to wait around while, by the UPS map, my package was sent north from Missouri to Lake Michigan, etc., etc., and sat in my city of Gaithersburg 3 days before they delivered it??? I would have gone to get it if I could have found out where it was in Gaithersburg. Never again UPS. My mechanic needed almost 3 hours install the of wiring and connections kit (Tekonsha 18685), so I don't think installation was simple, easy, quick and something that an amateur could do. The box comments were written by a raving optimist. But when installed, the kit worked correctly to connect my Tacoma lights to my trailer. Yippee!!! Greg, your salesperson was a pleasure to deal with, but tell him I said to talk people out of snail mail. 651749

    I choose the Tekonsha, part # 118685, over the Curt, part # C56349, but they're extremely similar. The only reason I choose the Tekonsha is because it has a higher amp capacity than the Curt. This can help from overloading the harness if your trailer has a lot of lights that draw a substantial amount of power. It's not a significant difference but you never know if you may need the higher capacity at some point.
