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. Circuit-protected converter guards against shorts.


Features:

  • Provides a 4-way flat trailer connector at the back of your vehicle to power your trailer's signal lights
    • Compatible with 5-pole, 6-pole and 7-pole adapters (sold separately)
  • Connects quickly and easily - no cutting or splicing of wires
    • Locate connection points behind tail lights
    • Plug in T-connector
  • Includes circuit-protected tail light converter to ensure that your vehicle's wiring matches that of your trailer
    • Provides protection against electrical shorts and overloads
  • Constructed of 16-gauge bonded wire
  • Comes with dust cap for 4-way flat connector


Specs:

  • Maximum amperage:
    • Stop/turn lights: 2.1 amps per circuit
    • Tail lights: 5 amps per circuit
  • 1-Year limited warranty


Installation

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 tail lights. You will have to remove the tail light assemblies to access this harness.


T-One Connection Location Points Behind Tail Lights

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.


Circuit-Protected 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.


This converter safeguards itself and your vehicle against possible electrical shorts and overloads with integrated short circuit protection. Just install the connector as indicated and rest assured that the wiring system of your vehicle will remain feedback-free.

excellent product,worked just fime.. if you remove bumper cover[simple] you can attach harness to exicisting wiring for a professional installation.

Fast and easy installThe best easy install around.... only took 15 minutes and that time was mostly spent on taking the tail lights off and putting back on. Having some problems now after several years so might just buy another one!!



by:

Very happy with the product. This was a lot easier than I thought. Took more time to take out the tailights than it did to install the harness. All was complete in 30 minutes. Snapped together very easily
Ordered on Sun was at my door on Tue.

The product was exactly like it was descriped. It was literarally plug in and go. It was somewhat difficult to run the trailer wires to the passenger side. But all said and done, it works perfectly.



by:
2008 Honda Ridgeline

This product was a delight to install! Everything went as described in the install sheet. It was truly a plug n play install.

I would suggest that a picture of where to 'stick' the control module be included in the instructions, it would have made the install sheet more valuable!.



by:

Outstanding Customer Service during order phase, harness arrived superfast, I had pre-read installation instructions and had tools at the ready. It took less than 30 mins from start to finish including testing my trailer lights. Thank you all for such professional service.

2008 Honda Ridgeline

I ordered a traveling wiring kit for my 2008 honda ridgeline... The package came quickly, ordering and finding this product was very easy. The kit was fantastic! I have wired trailer lights 8-10 times in the past and this was by far the easiest kit I have ever used... great product. Great service. I couldn't be happier, thank etrailer!

Easy ito install - use a peice of wire to pull connectors through openings from beneath car into tail light cavities prior to installing hitch. You can incase wires in plastic flex tubing - if desired - for additional protection.



by:
2011 Honda Ridgeline

Ordering and delivery were superb. Order confirmation and notice of shipment the same evening.
The product (trailer tow wiring loom for a Honda Ridgeline) appears of good quality and durable. A handful of wire ties was included, which was nice. The install took about 90 minute and is a fairly obvious operation. Better photos in the instructions would be good. Be sure you know how to unsnap the Honda wire connectors - it is NOT obvious at all - ETrailer has a short video at the product's site showing the proper way to do it and it was a BIG help.

I would buy this product again. And I will be doing business with ETrailer again.

2006 Honda Ridgeline

This fit a 2006 Ridgeline RTS perfectly. One year in it's still working like a champ. I used this to replace another vendor's tow harness which quit working after several years of service. Cheap, easy, does what it's supposed to do.

  • Adding 7-Way Trailer Connector to 2008 Honda Ridgeline
    If your 2008 Honda Ridgeline came with a factory installed 7-Way trailer connector it is possible that # HM40975 will fit. You need to look at the wiring harness that plugs into the back of the factory 7-Way. If it looks the same as the back of # HM40975, see picture, then you can use it. If your Ridgeline did not come with a 7-Way then to add one you will start by installing a 4-Way (unless the truck already has one) using # 118400. Then you will need to install 4- and 7-Way installation...

  • Left Turn Signal and Brake Lights Do Not Work On Trailer or 4-Way on 2006 Honda Ridgeline
    You have done all of the correct testing and it does indicate that the converter in harness # 118400 has gone bad and needs to be replaced. There could be any number of reasons for a converter to go bad. It could be a short on the trailer that blew the box, protecting the vehicle wiring like it was designed. Check the trailer to make sure the grounds are all attached to clean bare metal surfaces. Also make sure that the trailer and vehicle side connectors are free of dirt and corrosion....

  • Adding a 7-Way Trailer Connector to a 2006 Honda Ridgeline
    It would appear that the 2006 Ridgeline either came with a factory installed 7-Way connector at the back or it didn't. If it isn't present then your model must not have come with it. But you can add one. To add a 7-Way you will first need to install a 4-Way using wiring harness # 118400. Then you can install 4- and 7-Way kit # ETBC7 to add the 7-Way and retain use of a 4-Way as well. I have linked some videos that show and explain the ETBC7 installation for you. If you also need a brake...

  • Recommended Hitch, Wiring, and Towing Setup for a 2007 Honda Ridgeline
    Good news! I can help you outfit your 2007 Honda Ridgeline with all the parts you mentioned to be ready to tow. The hitch I recommend is the Draw-Tite # 75280, because of its high towing capacity. It's important to note that you will be limited by your lowest rated part which may end up being your vehicle so you will want to be sure to check your owners manual for any limitations. The 4-pole harness I recommend for your vehicle is the # 118400, which will plug into your vehicle's existing...

  • Where is the Brake Controller Connector Located Under the Dash on a 2009 Honda Ridgeline
    The factory brake controller connector under the dash is not all that visible but it is fairly easy to locate. It is a 4-pin connector that is located underneath and left of the steering column. It will be taped to another harness near the brake pedal. Once you locate the connector you will know it is the right one if it mates to the Tekonsha Wire Replacement for Honda Ridgeline and Pilot, item # 3070-P. A little bit of searching is required. Sometimes the connector is completely covered...

  • Adding a 7-Way Trailer Connector to a 2007 Honda Ridgeline with an Existing 4-Way Connector
    To add a 7-way trailer connector to your 2007 Honda Ridgeline our # ETBC7 kit will do exactly what you want. It's intended for electric brake controllers but not having a controller connected won't hurt anything. And if you install the # ETBC7 you'll already have everything you need to add a controller later. Another option is to install the adapter, part # 37185, that is included with the # ETBC7 kit and not connect the other three wires. This way you'll have a 7-way connector but...

  • Trailer Hitch and Wiring Recommendation for 2007 Honda Ridgeline
    The most concealed trailer hitch we have for your 2007 Honda Ridgeline is the Curt hitch part # 13385 which only will have the hitch opening visible underneath the rear bumper. See attached picture to see what it looks like installed. For trailer wiring you'd then want the Tekonsha kit part # 118400 as the Tekonsha brand it the most reliable option we carry.

    The Tekonsha Modulite Protector 5-Way Flat KIT # 119177KIT referenced in your question is a universal harness that can be installed on your 2008 Honda Ridgeline. This hardwire kit will require you to splice in all of the wires to the tail light wires on your Honda Ridgeline to give you the needed 5-Way to connect with your boat trailer. With this in mind, an easier option will be to simply install the Tekonsha T-One Vehicle Wiring Harness # 118400. This custom-fit, 4-Way harness will...

  • Trailer Wiring Kit For Safe Operation and Warranty on a Honda Ridgeline
    To answer your question, there is a federal law that says that the vehicle manufacturer must provide warranty repair on the vehicle as long as the aftermarket device is not the actual cause of the malfunction or breakdown. In that case you would be responsible for any repair. That being said, I have never ran into a situation where trailer wiring caused a customer to be declined for warranty service. Most car dealers will service the vehicle under warranty no matter the cause of the malfunction,...

  • Setting Up 2008 Honda Ridgeline For Towing Landscape Trailer
    The Curt # 13385 Class III hitch would be a great choice for towing your mower. We typically recommend a weight distribution hitch for trailers that weigh more than half of what the vehicle weighs, but since you're right on that line, and because you have the ability to shift the mower fore or aft of the trailer axle to keep the tongue weight close to the recommended 10% of the trailer weight, you should be fine without weight distribution. You will also need a trailer wiring harness...

  • Parts Needed to Install Redarc Tow Pro Elite Brake Controller in 2008 Honda Ridgeline
    To install the Redarc Tow Pro Elite part # RED44FR in your 2008 Honda Ridgeline that does not have any trailer wiring you'd first need to start with a 4-way kit that fits your vehicle with the # 118400 and then convert it to a 7-way with the part # ETBC7 which also comes with everything needed to install wire in the brake controller as well.

  • Installing 7-Way Trailer Connector on 2007 Honda Ridgeline
    Unless the vehicle is equipped with the OEM 7-way (apparently it's not), the 12-volt circuit wouldn't be ran from the front of the vehicle. You can run the circuit yourself using a length of 10 gauge wire like part # 10-1-1. You'll need to run the wire through a 40 amp circuit breaker, part # 9510. You'll want to route the wire in such a way that it avoids anything that's hot or moving, like suspension, steering and exhaust components. If you're wanting to install a brake controller,...

  • 7-Way Recommendation for a 2008 Honda Ridgeline
    If you have a factory 7-way at the rear of your 2008 Honda Ridgeline but there is no voltage at any of the pins most likely you would need to check the fuse/relay panel to install/replace the towing related fuses/relays so that the 7-way would function. The only way we offer to install a 7-way on your vehicle would be to first install a 4-way like # 118400. 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...

  • Trailer Wiring Harness for 2007 Honda Ridgeline that Will Work with LED Trailer Lighting
    The Curt Trailer Wiring Harness that you referenced, part # C56175, is not recommended for use with vehicles that have LED lights (but is compatible with trailers that have LEDs). This harness requires you to cut and splice wiring to install it. I can offer you an easier solution that will not require any cutting of wires.

  • Troubleshooting 4-Pole Wiring on Re-Wired Boat Trailer
    The best first step is to isolate the problem to either the tow vehicle wiring or the trailer. Disconnect the boat trailer's 4-pole. Use your vehicle battery (or a spare battery) to directly test the trailer lighting on its own by connecting the 4-pole ground pin to the battery negative terminal and one by one connecting the battery hot terminal to each of the other pins on the trailer's 4-pole. If the trailer lights behave properly when connected in this manner, then you know the problem...

    To me it sounds like there was a short on your trailer which caused the Tow Ready Wiring Harness # 118400 that you referenced to short out as well. Bizarre trailer light behavior is usually caused by a shorted out converter box or bad tail light grounds. I would check the condition of the grounds of the tail lights first. Some assemblies ground through the mounting hardware, if that is what you have then you should check to make sure the assemblies are attached to a clean, metal surface. Since...
