Installation
This custom-fit T-One connector plugs into your vehicle's wiring harness, which is located on the driver's side and passenger's side, either behind the tail lights or along the frame rail. If your wiring harness is behind the tail lights, you will have to remove the tail light assemblies to gain access.
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.
Tail Light Converter
A tail light converter 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. The tail light 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.

Quickly and easily install a 4-way trailer connector on your vehicle with this custom wiring harness. T-One connector plugs directly into existing wiring - no cutting, splicing or tapping required. Includes tail light converter.I installed this wiring kit ( Tekonsha 118496) on a 2007 2 wheel drive Tacoma. All components appear to be of decent quality and everything fit and worked as it should. I added protective covering to the wiring running underneath the vehicle to the right side tail light and to the 4 flat plug. When looking for a kit, I was impressed with the information and reviews supplied by etrailer. Compared to wiring a trailer hook-up from scratch, this was a breeze! Shipping was reasonable and took less than 2 weeks to get to Canada.
Bryan - 03/01/2022I had been looking for a solution to securely add a 4 way flat connection and be able to plug in my Rear LED light bar to. The product was accurate and very easy to install in less than 15 minutes. All plug-n-play. Very happy with the final result. Thank you

One year follow-up: The product works as advertised. No problems at all over the last year. Installation was simple and straight forward. One comment only about the optional mounting bracket for the 4-pin connector: get/use better self tapping screws before you attempt to mount the bracket. Even though I pre-drilled the supplied self-tapping screws are very soft and snapped off. I then relocated the bracket and used my own (hardened) self-tapping screws. Overall I'm very happy with the product.
This was super easy to install and I did it in about 15 mins.
I'm very happy to have a working trailer connector.
Easy to order, intuitive website. Package deliver in just a couple of day, well wrapped and with all the components in it. Here’s the best part, unlike the Reese hitch which is advertised as a 30 min installation but could take the regular Joe two hours with a helper and over that by himself, this harness would take less than 30 minutes thanks to the YouTube video with clear step by step instructions. Btw, delivery is only 4 bucks. Highly recommended.
AlexF - 08/10/2021While the directions were clear the associated video they suggested was spot on perfect.
didn't take long and works like a charm!
The wiring system was pretty straight forward. The video pretty much said all I needed to know. I'd rather use this set-up than any guy at a hitch shop doing a quick splice to the wiring in my truck, any day. The only thing I did differently from the video was put my wiring in the black conduit that you can buy pretty cheap at any auto parts place. This change will keep the wires from chaffing and makes the whole job look more professional.
Very easy to install with no background knowledge required. Took me about 15 min for our 2012 Tacoma. Installed a year ago and has been working well since.
Anja - 01/10/2022This wiring harness was just what I needed! I bought a used 2014 Tacoma that someone had hacked up the wiring at the tail lights to tap in and hook up trailer wiring. It was a mess and rather than repairing what had been done incorrectly I put it back to stock and ordered this harness after watching the [online] video. It arrived quickly and installed easily! Very happy with the product and etrailer.com!
I’m very happy with the fast shipping and that you add an instructional video for all your products. etrailer seems well organized and pro customer.
Great services. trailer pulls great for my little truck. Easy to install hooks and hanging items inside. Prices are very competitive, this was the best price and seems like I got more for my money. Staff did great job explaining total weight my truck can handle with this trailer. recommend if you are looking for a trailer to give them a chance. I would expect you to get the outstanding service I received.
Purchasing the wiring harness with the trailer hitch just makes sense. You know that you receive the right harness for your type of vehicle.
2014 Tocoma..The wiring install, went slower the the hitch install.
the main reason was the taping of the wires to the truck wiring and getting up and down. (time was 50 minutes)
Install the driver side first, only the plug is placed with the tail light,
install the passenger next, only the plug is placed with the tail light.
Tape the new wiring to the stock wiring, start with the tail lights and work down you will find you have just the right length of wire. I taped the 2x2 black connector to the wiring harness. If the wires were 6 inch's longer on both sides, I would have used the two sided tape and stuck the connector on the frame
K.L. - 02/09/2015After a year used and sometime submerge in saltwater. This wire harness still work like day one
1 year review very satisfied and I'd buy again. Online videos prepared me for a weekend warrior garage floor installation.
The wiring harness and plugs fit snugly,securely and are still working correctly. The inline tail light connectors mean no cutting or half-tapping wiring. I tucked the wire harness box and 4-wire flat connector into one of the inside trunk sidewall storage coveys. This keeps all open connectors out of dirt and weather. When I need the 4-wire flat connector I reach in, uncoil it and close it between the hatch and rubber seal. For one of my trailers I carry a 18" 4-wire flat extension to reach the short wire on the trailer tongue.
I recommend you stretch out the harness for test fit to see the best fit before zip tying in place. This is not a product issue but the only hassle is getting the power wire from the harness box in the back of the vehicle, safely thru the body and frame and to the battery under the hood. The harness box had plenty of wire to reach the battery. There are hot wires in the back of the vehicle but I wanted a direct connection to the battery.
parts were on time and the fit was correct.Used all year with no problems.
Thank You

The wiring harness was fairly easy to install and directions were spot on. I recommend using flex tubing to protect your wiring; better to be safe than sorry.
This is a great product that was super easy to install. I had it wired up in less than an hour. Anyone could install this wiring harness.
Great product! Easy installation.
Edmund - 12/16/2021I bought this wiring harness to power an LED light kit I received at Christmas time for my 2018 Tacoma. The only hard part about the installation was running the power wire from the battery to the rear of the truck. Besides that, the installation was pretty easy.
Michael D - 03/07/2020Vet easy to install. Ran it through black corrugated tubing to protect wires. Works great! Highly recommend this product & etrailer.com!
Larry - 07/01/2021Package included everything. Video tutorial was very helpful. Everything works as advertised.
Excellent product, easy to install, no splicing of wires, would definitely recommend
Installed wiring harness in 15 minutes
Installed on a 1997 Toyota T-100. It took about 30 minutes. Everything was easy to install. It took a few minutes to get the truck plugs pulled apart (probably hadn't been pulled apart before). The plugs on this harness plugged right in with an audible click. I used the included cable ties as well as a few of my own to secure the wiring under the truck. Now all my trailer lights work, and I don't have to worry about any more splicing. I wasn't sure the passenger side wiring was long enough to reach across the truck, but it made the distance with a little room to spare.
I decided on this product after spending most of a Saturday splicing and checking connections. I was trying to find out why I didn't have right signal or brake on my trailer. Truck's lights worked fine, but the trailer's lights didn't. I even checked the trailer while connected to a friend's truck, so I knew the problem was on the truck's end. I put all of the original truck wiring back in place, checked all the lights on the truck, installed this product, hooked up the trailer, checked the trailer lights, and now everything works.
Thanks e-trailer.
