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.

2007 Toyota Tacoma
I'll begin with the fact that I am not very handy. This wiring harness was perfectly engineered to be idiot proof. I was able to install the whole thing perfectly, without incident, in about 30 minutes. I do not have a trailer hitch receiver beneath the bumper. I just have a hitch ball on the bumper, so I fed the end through the spare tire crank slot. Everything works perfectly.

I 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

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.

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.

Another year 2nd gone by and the T-One harness and connector are still working perfectly. I periodically spray the 4 pin connector with wd-40 to prevent corrosion maybe twice a year. The contactspins look good and work perfectly.

2009 Toyota Tacoma
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.
by: Rainer06/22/2020
As always ease of install with these kits. Just a walk in the park even taking my time and messing around in the garage for a bit while kit took ten minutes to install
by: Gary05/30/2020
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.
by: Tom03/17/2022
While the directions were clear the associated video they suggested was spot on perfect.
didn't take long and works like a charm!

by: Rex A. 08/01/2017
I gave you a 5 star even though UPS tried to mess up your excellant delivery time. they sent it to the wrong PO so instead of getting it 3/17 it came on 3/20. it attached easily per instruction and video. the only improvement I made was to encase all the wiring in flexible conduit. when finished everything tested perfect. thank you very much.

Awesome, I can't thank you enough for this.
Like factory made - VERY easy to install.

Very well-made.
If you are looking for wiring harness - this is the one to buy.

2014 Toyota Tacoma
I had received multiple quotes to install a hitch on my 2014 Toyota Tacoma. All were around $400. So I did a little research and found the etrailer.com site. I found I could buy the hitch, the wiring harness and ball myself for less. The installation video they provided me gave me the confidence I could do the install myself. Now it's on and the entire process couldn't have been easier. If you can use a socket wrench and screw driver you can install your own hitch. Piece of cake!
by: K.L.01/06/2014
2014 Toyota Tacoma
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

I have used the the trailer connection on 5 different days for about 1 hour each time, two weeks ago I had to used the trailer to help move a friend of ours and it was raining so the lights was on all the time. the trip was 12 hours,there and 7 days of short trips and on the way home about six hours in to the return trip i stopped for fuel and when I started the truck I lost the tail lights and the brake lights,blown fuses. I stopped at a auto parts store and picked up some new fuses,when i turned on the lights the new tail light fuses popped and when I stepped on the brakes, the new brake lamps fuses popped. We stopped for the night, I will not drive a truck and a trailer at night without lights.The next day, and a hundred lighter, I got home, I disconnected the trailer and replaced the fuses. The fuses stilled popped. I opened the tail lights and disconnected the left tail light trailer connection and the fuse sill popped, and i disconnected the right tail light trailer connection and the fuses held. I will pull out the bad harness and replace it with a factory tow harness more money and more time to install but I no more problems and I will order a trailer brake to plug in to the stock wiring.

2005 Toyota Tacoma
The wiring for my trailer hitch arrived very quickly. I had purchased the hitch a while ago and installed it myself using the instructions and watching the videos from etrailer. It was pretty easy. I had dreaded having to trace wires and have unsightly splices . The wiring fit perfectly for my 2005 Toyota Tacoma. Unplug the taillights, plug the trailer wiring in, put the taillights back on the truck. I also installed the trailer plug that allows me to use 4 pin or 7 pin wiring. That was pretty easy too. Just make sure you have some self tapping screws on hand. Would definitely recommend all the products i’ve purchased from etrailer.

Still very happy with my purchases. I bought a bumper, trailer hitch , and wiring harness. I installed all myself using the Etrailer instructions and videos. Would recommend to anyone looking for good products that you can install yourself to save a ton of money!

2007 Toyota Tacoma
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.

- How To Install a 7-Way Trailer Connector On a 2005 Toyota TacomaIn order to install a 7-way trailer connector on a 2005 Toyota Tacoma you'll first start with a 4-way, the T-One Vehicle Wiring Harness with 4-Pole Flat Trailer Connector part # 118496 which is plug-in-play. Then, you can adapt this to a 7-way using a kit like the 4 to 7-Way with 4-Way Adapter part # ETBC7. This kit also has everything you need to install a trailer brake controller commonly used on trailers with a 7-way connector. If you need one, I recommend Tekonsha Primus IQ Trailer...

With everything installed according to the instructions, linked for reference, have someone sit in the cab to operate the brakes, lights, and turn signals while you test the wires on the harness. First test the wires that go into the converter from the tail lights. If you do not get a signal then make sure the connectors...
view full answer... - Recommended Wiring Harness For a 2010 Toyota Tacoma It sounds like you need a 4-pole flat for the 2010 Toyota Tacoma to illuminate the trailer lights. For that I recommend T-One Vehicle Wiring Harness with 4-Pole Flat Trailer Connector part # 118496 which has a converter so it is compatible with your LED lights. Tekonsha is a reliable brand that is known to last a bit longer compared to the other brands especially the converters. I have attached an installation video for your reference.

Otherwise you will experience the problem you are having. Usually the yellow wire is left turn and stop (on a two wire system) and the green wire is right turn and stop when using a wiring harness like the Tow Ready Custom Fit Vehicle Wiring, # 118496, which is the custom fit for your 1998 Toyota T-100.

Use a circuit tester like # PTW2993 and check the connector. You should find a constant 12-volt power source and a stop light switch power source that has voltage only when the brake pedal is pressed. If those circuits are working in the connector, you can use the wiring going...

The controller box mounts under the dash where it's out of sight, where you won't bash your knees into it when you enter/exit the vehicle. The trailer brakes are controlled by the control knob which is installed within the driver's reach. An unused switch knockout on the dash or center console is the...

You will also need no drill mounting bracket # 18140 With that done you will need to replace the connector on your 2007 Little Guy tear camper with the # PK12706 to replace your 4-way connector, and more # 10-1-1 to run from the 7-way to the battery on your camper.

This will plug right into the factory wiring you have now to give you an all new connector.
