Features to know about

Plug-and-Polish Your Ride: Custom-Fit T-One Vehicle Wiring Harness

Ever struggle with basic wiring for your trailer? With the T-One Vehicle Wiring Harness, installation is a breeze. Just plug it directly into your vehicle's pre-existing wiring—no cutting or splicing required. You'll get a sleek, custom-fit connection designed specifically for your vehicle, providing clean and polished signal light power!

Prevent Electrical Overload: Powered ModuLite Converter

Worried about straining your vehicle's electrical system? The ModuLite Powered Converter is your solution. It connects directly to your car's battery, ensuring your trailer gets consistent power without overloading your vehicle’s electrical circuits. This clever design means your vehicle stays protected while towing, minimizing the risk of blown fuses or damage.

Stay Corrosion-Free with Durable Construction: 16-Gauge Bonded Wire

Long-term trailer use can lead to corrosion troubles, especially in harsh weather. This harness comes with 16-gauge bonded wire engineered for durability and longevity. Whether rain or shine, the solid construction keeps your connections free from corrosion, extending the life of your trailer lights.

Simple One-Wire Operation: Tail Light Converter Function

Struggling to merge brake and turn signals? The built-in ModuLite tail light converter smartly combines your vehicle's brake and turn signal functions. This streamlined one-wire system makes your trailer lights work perfectly with your vehicle’s three-wire system, simplifying your towing experience.

Universal Signal Compatibility: 4-Way Flat Connector

Not sure which connector suits your trailer? The 4-way flat connector is a versatile choice that easily adapts to 5-pole, 6-pole, and 7-pole adapters. Enjoy seamless connections with a range of trailers, adding flexibility to your towing needs without the need for separate connectors.

Peace of Mind with Maximum Amperage Specs

Concerned about circuit safety while towing? With a maximum amperage of 2.1 amps per circuit for stop/turn lights and 4.2 amps per circuit for tail lights, this harness keeps everything under control. Drive with confidence knowing your setup is within safe operational limits, ensuring dependable performance mile after mile.

Specs

Electrical Specifications

  • Maximum amperage:
    • Stop/turn lights: 2.1 amps per circuit
    • Tail lights: 4.2 amps per circuit

Warranty

  • 1-Year limited warranty

Installation Instructions:

  • 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 interior trim panels in your rear cargo area. 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 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 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.
  • 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.

Note

This will not affect how the tail lights on your vehicle operate.

  • Parts Needed to Install Brake Controller in 2009 Toyota RAV4
    For your 2009 Toyota RAV4 there isn't a plug and play style of brake controller install harness so you'd have to hardwire one in with the # ETBC7 plus a 4-way kit part # 118412 if you do not have a 4-way already. Those two parts would be all you need to install the brake controller part # 39523 that you mentioned in your 2009 Toyota RAV4. I attached an install video for the ETBC7 installed in a Rav4 similar to your 2009 model.

  • Parts Needed to Install 5-Way Trailer Wiring on 2008 Toyota RAV4
    The simplest way to install a 5-way on your 2008 Toyota RAV4 would be with the Tekonsha kit part # 118412 first for a 4-way and then use the # 20036 to convert to a 5-way as there isn't a 5-way kit that fits directly to your vehicle.

  • Brake Controller and Wiring for a 2007 Toyota Rav4
    All that you need to complete your installation is a brake controller and an installation kit and a 4-Way wiring harness which you already have. The Tekonsha Prodigy P2, # 90885 is a great unit, and I would highly recommend it. The Electric Brake controller Installation Kit, # ETBC7, contains everything needed to install your controller, including the 7way connector with mounting bracket, wire, connectors, circuit breakers, even the zip ties! We have detailed instructions for installation...

  • Troubleshooting a T-One Vehicle Wiring Harness # 118412 Installed on a 2006 Toyota RAV4
    It sounds like the problem could be the converter box of the T-One Vehicle Wiring Harness # 118412 if the connections are good and the ground is good. The best way to test the box would be to get a circuit tester like the part # PTW2993 and test the wires going into the box and then out the other side. I would start on the left blinker signal wire on the input side of the box. You will want to test for intermittent voltage on this wire, and then again on the output side of the box. If...

  • How To Install a Trailer Wiring Harness to a 2011 Toyota RAV4
    You will not want to connect your trailer wiring directly to the wiring harness of your 2011 Toyota RAV4. You will need to isolate the trailer wiring from the vehicles sensitive circuitry, so it does not put a strain on the system and cause your vehicles wiring harness to be overloaded and fail. I would recommend to use the Tow Ready T-One Wiring Harness, part # 118412. This wiring harness will plug into connectors located behind the vehicles tail lights and comes with a powered Modulite...

  • Trailer Wiring and Hitch Recommendation for 2012 Toyota RAV4
    The best trailer wiring harness we have for your 2012 Toyota RAV4 is the Tekonsha part # 118412 which installs easily and has the most reliable converter box. Now the towing capacity looks to be between 1,500 and 2,000 lbs depending on how it's equipped so to find out for sure what your number is you'd need to contact Toyota with your VIN. For trailer hitches my favorite options are the Ecohitches for your vehicle since only the hitch opening hangs below the rear bumper. If you have a...

  • Why Is Separate Power Wire Required For Trailer Harness On 2010 Toyota RAV4
    Because of the amperage draw for the wiring harness like part # 118412 or part # C56165 for your 2010 Toyota RAV4, a separate wire is necessary because many of the wires on other circuits are unable to handle the draw. Attaching the wire harness power lead to one of the other wires might cause damage to the vehicle electrical system.

  • Best All-Around Hitch for a 2011 Toyota RAV4
    For an all-around hitch for your 2011 Toyota Rav4 a 2 inch Class III hitch will be the way to go since they have higher towing capacities and more accessories built for them. The hitch I would recommend is the etrailer # e98864. This hitch has the highest capacities and lowest price so it would be your best option. It has capacities of 525 lbs tongue weight and 3500 lbs towing. I attached an install video for you to check out as well. Since you wanted to do some towing you might be interested...

    The EcoHitch Hidden Trailer Hitch Receiver # 306-X7174 weighs 37lbs. This weight along with your Ball Mount # 3371803307 (9lbs) will need to be added to the payload when considering towing a trailer. Anything you add to the vehicle you will need to calculate into the equation and ensure you do not exceed your Gross Vehicle Weight Rating (GVWR) on your 2011 Toyota RAV4 Limited with the V6.

  • T-One Trailer Wiring Harness Installation on a 2011 Toyota RAV4
    Yes, installation of the T-One Wiring Harness, item # 118412, will be essentially the same on the 2011 RAV4 as it is on the earlier year models like the ones in our videos, and in the instructions, see links. The only difference may be accessing the rear of the tail lights, for connection of the wiring harness. Since the vehicle design has changed a bit, the interior panels may have changed some and removing them may be slightly different. We have not had the opportunity to install wiring...

  • What is the Power Wire for and Running Lights Not Working on Trailer Wiring Harness for Toyota Rav4
    The power wire in wiring harness # 118412 actually provides most of the power for the trailer lights. This helps protect the vehicle wiring. The lights should come on when you turn on the vehicle lights so what you are seeing is not normal. Check the connections at the tail lights and look for any dirt in the connectors or a bent pin. Also make sure that the converter box is grounded to a bare metal surface. On the trailer side make sure the main connector ground and the grounds for...

  • Do I Need A 7-Way To Tow an Aliner Ranger Trailer With a 2007 Toyota RAV4
    According to my research, the Aliner Ranger Trailers did come standard with 10" electric brakes so you will need to install a 7-way trailer connector and a brake controller on your 2007 Toyota RAV4 in order to tow it. For this, you will need a combination of the T-One Vehicle Wiring Harness part # 118412 and the 7-Way RV Upgrade Kit for Trailer Brake Controller Installation part # ETBC7L. If you use the 7-Way RV Upgrade Kit for Trailer Brake Controller Installation with the Curt Echo...

  • Does Curt Hitch part # C13149 Fit a 2012 Toyota RAV4

I attached an install video for you to check out as well. If you wanted to do some towing you might be interested in etrailer ball mount kit # 989900.

  • Will the Spare Tire on a 2008 Toyota RAV4 Interfere with Towing a Utility Trailer
    The spare tire should not be a factor if you are towing a trailer. It is a concern for things like bike racks though. With Curt trailer hitch # C12108 installed we have determined that from the center of the hitch pin hole straight back to the distance required to clear the spare tire is approximately 7 inches. With a ball mount installed the coupler on the trailer will probably be slightly rearward of the spare and of course lower. The only issue is that on Class II trailer hitches you...

    The first thing you need to install a brake controller like the Curt Echo is a 4-way harness confirmed as a fit for your 2012 Toyota RAV4 if you don't have one already. For that you'd want the Tekonsha part # 118412 which is easy to install and more reliable than other options overall due to a better designed converter box.

  • Can 4-Way Trailer Connector be Routed to the Outside of a 2009 Toyota RAV4
    To route that 4-Way connector from the interior of your 2009 Toyota RAV4 to the exterior you can cut a slit in the grommet. After everything is installed though be sure to seal it back up using some silicone such as # 0160297 so moistures and fumes don't get inside the vehicle. You can run all the power/brake output wires at the same time. If you wanted to you could also use the 12 volt power wire for the # ETBC7 for the regular 4-Way harness. But since you are running wires anyway you...
