Features to know about

Effortless Installation: Plug-and-Play Custom Wiring Harness

Say goodbye to the hassle of cutting, splicing, or tapping wires in your vehicle. The T-One Vehicle Wiring Harness features a plug-and-play design, making it simple to install on your vehicle's existing wiring system. It connects directly to your car, providing a seamless transition for powering your trailer's signal lights.

Protect Your Vehicle's Electronics: Built-In Tail Light Converter

Transitioning from your vehicle's three-wire system to a trailer's two-wire system has never been easier. The T-One Harness includes a built-in tail light converter that harmonizes your car's brake and turn signals. This feature not only ensures compatibility but also safeguards your vehicle's electrical system from potential overloads or faults.

Adaptable for All Trailer Types: Compatible with Multiple Adapter Types

Whether you're towing a small utility trailer or a larger camper, this harness is ready to meet your needs. It's compatible with 5-pole, 6-pole, and 7-pole adapters, giving you the flexibility to connect trailers of different types by attaching the right adapter. This makes it an all-in-one solution for various towing situations.

Stay Clean and Protected: Equipped with a Dust Cap

Keeping the connection points clean and free from dust or grime is crucial for long-term reliability. The T-One Harness includes a dust cap for the 4-way flat connector, protecting it from the elements and ensuring your wiring remains in optimal condition between towing uses.

Durable Construction for Reliable Performance: 16-Gauge Bonded Wire

Built to last, the harness uses durable 16-gauge bonded wire designed to withstand the elements and regular use. This robust wiring guarantees reliable performance, ensuring your vehicle's signal lights consistently mirror those of your trailer, keeping you safe and visible on the road.

  • Magnetic Towing Lights That Only Require A 4-Flat On The Towing Vehicle
    Hi Roger! What you are looking for would technically be referred to as flat tow lights on our site and we definitely have options for what you need. I wasn't sure if you were wanting LED or incandescent, so here is one of each: LED: Optronics Universal Magnetic Tow Lights - Red LEDs - 20' Wiring Harness with 4-Way Flat Trailer Connector # TLL21RK Incandescent: Optronics Universal Magnetic Tow Lights - 20' Wiring Harness with 4-Way Flat Trailer Connector # TL21RK Both of these only need...

  • What is Needed to Install a Brake Controller and 6-Way Trailer Connector on a 2008 Honda Pilot
    Since your trailer has a 6-Way connector installed you most likely have one of 3 wiring situations on your trailer. The first, and most likely, is that your trailer has electric brakes and a power wire to maintain a battery for auxiliary functions. The second is that you have the same power wire and backup lights at the rear of the trailer. The third, and least likely but possible, is that your trailer has hydraulic surge brakes and a coupler with electric backup lockout. If your trailer...

  • 2006 Acura MDX Trailer Hitch and Wiring Recommendation
    The owners manual for your 2006 Acura MDX will be the final authority on the towing capacity, but my research indicates that it would have 3,500 lbs of capacity. For a trailer hitch we have the Curt part # 13328 which is a fit and would work well. A local garage or trailer rental place would have no problem with this either. For trailer wiring you'd then want the Tekonsha kit part # 118336 which is a confirmed fit and our most reliable wiring harness brand. Since you wanted to do some...

  • Recommended Items Needed To Flat-Tow 2000 Honda CR-V
    The Roadmaster XL Base Plate Kit, part # 1528-3 is a great fit for your 2000 CR-V. This kit has removable arms when you are not towing. For a tow bar I recommend the Falcon 2 Tow Bar, part # RM-520. This tow bar folds up against the back of your truck when you are not towing. For lighting I recommend the Roadmaster Tail Light Wiring Kit with Bulbs, part # RM-155. This kit includes the bulbs and does not require tapping into the vehicle wiring. The # 118336 harness is not designed for...

  • What Size Trailer Hitch Is Available for 1998 Honda Odyssey
    For your 1998 Honda Odyssey we only have 1-1/4 inch hitches available like the Curt part # C11067 which is our highest rated option. The 2-inch trailer hitches are usually only seen on larger vehicles that are going to have higher towing capacities. For trailer wiring the Tekonsha kit part # 118336 is super easy to install and also very reliable.

  • Can Curt Echo Brake Controller part # C51180 Be Installed on 2002 Honda CR-V
    As long as you have a 7-way trailer wiring connector at the rear of your 2002 Honda CR-V that has all trailer lighting functions active and an active 12 volt accessory circuit the Curt Echo Mobile brake controller part # C51180 is going to work well. If you didn't have wiring you'd first need to start with a 4-way like the Tekonsha part # 118336 which is a confirmed fit for your vehicle and then you'd have to adapt it to a 7-way with the part # 37185. You'd need to run the black wire...

  • 5-Way Recommendation for a 2008 Honda Pilot for Reverse Lockout Solenoid
    If you don't have a 4-way installed on your 2008 Honda Pilot you will need one first. For that you would want part # 118336. Now to convert that to a 5-way (the fifth circuit is the reverse light circuit) you would want the part # 20036. This product allows you to tap into the reverse light circuit of the vehicle so that it can be used to operate an electric reverse light solenoid. Check out the install video that will give you an idea on how it installs.

  • Troubleshooting Function Issues With Tekonsha Trailer Wiring Harness # 118336
    The Tekonsha T-One Vehicle Wiring Harness with 4-Pole Flat Trailer Connector # 118336 is a confirmed fit for your 2005 Acura MDX. I recommend using a circuit tester like # PTW2993 to troubleshoot. I recommend testing each function at the end of your 4-way connection. If they are working, then the issue is most likely with the ground wire on your trailers. If they are not working then you will want to test the individual functions on either side of the box. If the result is consistent,...

  • Is there a Difference Between the Curt and Tekonsha Trailer Wiring Harnesses for a 2004 Honda Pilot
    As far as how the Curt and Tow Ready trailer wiring harnesses for the 2004 Honda Pilot function and install they are the same. The guts in each of the converter boxes is not quite the same. The Curt harness # C55336 uses surface mount circuitry meaning components are soldered directly to a circuit board. The Tow Ready/Tekonsha harness # 118336 uses through-hole circuitry which you have probably seen before in just about everything. If it were me I would go with # 118336 because we here...

I've also linked the installation of similar harnesses # 118336 and # 43105 from other manufacturers also confirmed to fit your vehicle to help.

  • What is Purpose of Converter Box On Tow Ready T-One Wiring Harness # 118336 For 2004 Acura MDX
    The black converter box on Tow Ready T-One Wiring Harness, part # 118336, is for use with vehicles, like your 2004 Acura MDX that have separate turn and brake light wires. Some vehicles send only one signal per wire, creating what is called a 3-wire system: one wire for the left turn, one wire for the right turn, and one wire for the brake signal (common on vehicles with amber turn signals). A converter will reduce it to a standard 2-wire system needed for wiring a trailer. There are still...

  • Can Draw-Tite Trailer Hitch 75599 Be Used To Tow Pop Up Camper With 2004 Honda Pilot?
    The Draw-Tite Max-Frame Trailer Hitch Receiver - Custom Fit - Class III - 2" # 75599 you were looking at is a great option for your 2004 Honda Pilot EX-L and will be perfect for towing your pop up camper as long as it does not exceed the ratings of your vehicle or hitch. The # 75599 has a 350lb tongue weight rating and a 3500lb trailer weight rating and as long as your Pilot does not have more than 3 passengers it does as well. The towing capacity of your Pilot decreases with the amount...

  • Installing 7-Pin Trailer Connector and Optional Brake Controller on 2004 Honda Pilot
    You're right. Unless the manufacturer pre-wires for a 7-pin lighting harness, the kits will all be for a 4-pole connector as you already saw. However, upgrading that 4-pole to a 7-pin is no problem. We'll start by installing the Tekonsha # 118336 4-pole wiring harness. This installs quite easily without cutting or splicing any wires. This will plug in near the rear hatch. I have attached a installation demo video. Next we will install an etrailer # ETBC7 7-pin receptacle. This will...

  • Adding a 7-Way Trailer Connector to a 2006 Honda Pilot
    To add a 7-Way trailer connector to your 2006 Honda Pilot you will first have to install a 4-Way using # 118336. I have linked a video showing how it installs. Next, to add a 7-Way (and also retain the use of the 4-Way) you will need installation kit # ETBC7. I have included some links that show and explain the ETBC7 installation for you. For a brake controller, if needed, I recommend the P2 # 90885. This is one of our most popular controllers because of how easy it is to set up and...

  • Is a Brake Controller Wiring Harness Connector Available on the 2005 Honda Pilot
    The Wiring Adapter, part # 3070-P will work on the Honda Ridgeline only. The 2007 Pilot does not have the provision for plugging in a controller under the dash. To install a controller in your Pilot, you will have to hardwire the controller, using our Brake Controller Installation Kit, part # ETBC7 (for a 7-way connector) or ETBC6 (for a 6-Way connector). The install kits contain everything necessary for installing your brake controller. Since your Pilot already has the 4-pole trailer...

  • Will Wiring Harness From 2005 Honda Pilot Fit 2005 Honda Element
    The wiring harnesses we offer for the 2005 Element like part # C59496 are hard-wired and are not a plug-in harness like part # 118336. The # C59496 includes the harness, and Modulite install kit and a circuit tester that helps find the correct wires to splice the harness to. The wires you need to locate are behind the vehicle tail lights. The installation instructions are included. I have attached a couple helpful articles you can check out.

  • Recommended Trailer Hitch for 2005 Honda Pilot
    Both Curt class III trailer hitch, part # 13328 and the Draw-Tite Hitch class III trailer hitch, part # 75599, are quality hitches. But the most popular hitch for your vehicle is the Curt hitch, part # 13328. Installation is relatively easy, even for a beginner. The Curt receiver simply bolts on to the inside of each frame rail. Both hitches require about 40 minutes of installation time. The Curt hitch does use two extra screws to attach the center bumper bracket above the receiver behind...

    The height of the trailer hitch when we measure for the videos can vary based on the year of the vehicle, inflation of the tires, or even how much cargo is loaded in the vehicle so the numbers we give are good to use as an estimate. If you check out the attached video of the Draw-Tite # 75270 being installed on a 2003 Honda Odyssey you can see that the ground to hitch height it 12 inches and from the center of the hitch pin hole to the rearmost edge of the bumper is only 4-1/2 inches.

I have added a link below for that item. Be sure to fill in your hitch brand and model number. Some customers find the the bolts thread smoother if they use a 1/2" Tube Brush # 814092 first.
