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.

  • 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...

  • 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...

  • 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.

  • 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...

  • 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,...

  • 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...

  • 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 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...

  • 7-Way Trailer Wiring Recommendation for 2005 Honda Pilot
    You will need to start with a 4-way (if you do not have one). For that you would want the # 118336. Now if your trailer does not have brakes all you would need is the part # 37185 as an adapter to convert the 4-way to a 7-way. If you do have trailer brakes you would need the # ETBC7 instead of the # 37185 and a brake controller. This kit comes with everything needed to wire up the 7-way and install a brake controller. For a brake controller I would recommend the Prodigy P2 Brake Controller...

  • 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...

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

  • Trailer Wiring Harness Port Location on a 2004 Acura MDX
    It should be under the threshold molding on the back edge of the cargo area, along where the door seals to the vehicle. It would not be behind the panel on the left or right side of the cargo area. I have added a link to the instructions for part # 118336. See page 4, it is the page that has the pictures for install 2001-current Acura MDX.

  • 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...

    In order to install a brake controller and 7 pole adapter, you first need to install the T-One Vehicle Wiring Harness with 4-Pole Flat Trailer Connector # 118336. I have attached a step-by-step installation video. Next you will need to install the Universal Installation Kit for Trailer Brake Controller - 7-Way RV and 4-Way Flat # ETBC7 to convert the 4-way to 7-way. I have attached a video for this as well. Finally, you will need a brake controller and harness. I recommend the Brake...

  • Hardware for Curt HItch # 13328
    The only hardware required are bolts and washers which are supplied with your Curt Hitch # 13328. If you need replacement hardware you can order our kit # RHK. 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. I have included a link to the hitch and brush.

  • Recommended Ball Mount for a Rise of 18 inches When Installing Draw-Tite # 75720 on a 2002 Odyssey
    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.

  • Recommended Trailer Hitch for 2006 Honda CR-V to Tow Motorcycle Trailer
    The Draw-Tite Max-Frame Trailer Hitch Receiver # 75690 referenced in your question is a great choice and is the hitch I recommend for your 2006 Honda CR-V. This is confirmed to fit your vehicle and will provide a 2 inch receiver opening with a 3,500 pound towing capacity. I do also recommend verifying the vehicle's towing capacity as listed in the owner's manual, as this will likely be the limiting factor. Based on the 19-21 inch hitch height of the trailer, you may simply need to use...

  • How to Route Trailer Wiring After Making the Connections on a 2004 Honda Element
    You are correct, the instructions, linked for reference, do not specify how you would run the 4-Way from the connection point on your 2004 Honda Element to he out side of the vehicle. There are a couple of ways you can do this. First, you can stow the 4-Way in the vehicle and then when needed, pull it out of the back door/hatch. You can close the hatch on the wiring as long as it is not pinched in a locking or hinging mechanism. The weather stripping on the rear door will prevent the...

This is a different brand connector but it does the same thing as the Hopkins Custom Fit Vehicle Wiring # 43105 and installs the same way so the instructions will work for you as well. The instructions I attached show you exactly where the panels are that need to be removed and how to remove them.

  • Trailer Running Lights Turn Off When Truck Is Started, Turn On when Truck Is Turned Off
    It sounds like a ground and/or short circuit problem. What you will want to do is disconnect the trailer from the vehicle. use a circuit tester like # PTW2993, to test the 4-Way on the vehicle side. If the signals are all coming through like they should, then you know the problem is on the trailer side. If the signals are not coming through correctly, the converter box could be bad. To test the converter, test the signals going into the converter from the vehicle, if those are correct...

  • Trailer Hitch Recommendation For 2007 Honda Pilot
    The hitch I recommend for your 2007 Honda Pilot is the Draw-Tite Trailer Hitch, part # 75599. This is a Class lll hitch and has a 2 inch receiver opening. The installation requires no drilling so if someone is handy with tools they should have no problem installing the hitch. You do need to make sure whoever installs the hitch uses a torque wrench to make sure it is properly installed. I have included a link to an installation video for this hitch on a 2008 Pilot. Although a different...

  • Brake Controller Installation on 2004 Honda CRV
    Honda does not pre-wire the CRV for a brake controller installation, so you will have to run a length of 10-gauge wire from the passenger compartment, through the firewall and engine compartment and under the vehicle to connect to the 7-pole connector at the rear. The brake controller output wire would connect to the # 2 pin on the trailer connector, which is sometimes labeled BLUE. I took a look at your order and saw that you did not order a taillight converter, part # 118336 for your...
