Quickly and easily install a 4-way trailer connector on your vehicle with this custom harness. Connector plugs directly into existing wiring - no cutting, splicing or tapping required. Converter is made using SMT to ensure superior performance.

    • Compatible with 5-pole, 6-pole and 7-pole adapters (sold separately)
  • Connects quickly and easily - no cutting or splicing of wires
    • Locate connection point in rear cargo area
    • Plug in connector
  • Includes a tail light converter to ensure that your vehicle's wiring matches that of your trailer
  • Constructed using surface-mount technology (SMT) for consistent, reliable performance
    • Maximizes trailer light yield and intensity while producing minimal heat
    • Ensures superior operation in rough road conditions
  • Comes with dust cap for 4-way flat connector


  • Maximum amperage:
    • Stop/turn lights: 3 amps per circuit
    • Tail lights: 5 amps per circuit
  • Limited 1-year warranty


This custom-fit T-connector plugs into your vehicle's wiring harness, which is located in your rear cargo area. The specific location for your vehicle is indicated in the included instructions.

It is recommended that you use a small amount of grease on all electrical connections - the plug on your automobile and the 4-pole connector itself - to help prevent corrosion.

Tail Light Converter with Surface-Mount Technology

A tail light converter is built into this T-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 the trailer. This 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.

Curt builds each tail light converter using surface-mount technology (SMT). This method of construction involves soldering electronic components directly to the surface of a printed circuit board. SMT eliminates the need for leads, which are used in older through-hole technology. The result is a circuit board that is smaller yet provides more routing area and that offers superior performance, reliability and durability.

Curt SMT Circuit Boards

Circuit boards constructed using SMT have been shown to perform better under rough conditions with excessive vibration than those made using the through-hole method. And where would vibration be more likely to occur than in towing applications? Curt converters also produce less heat, leading to increased durability and longer life. In addition, lower levels of resistance ensure better performance, especially for parts that operate at higher frequencies.

Each Curt circuit board is made using high-quality components that are pieced together in the most technologically savvy fashion, leading to greater predictability and reliability in functioning.

Curt T-Connector Vehicle Wiring Harness with 4-Pole Flat Trailer Connector - C55336

Average Customer Rating:  4.9 out of 5 stars   (203 Customer Reviews)

Quickly and easily install a 4-way trailer connector on your vehicle with this custom harness. Connector plugs directly into existing wiring - no cutting, splicing or tapping required. Converter is made using SMT to ensure superior performance.

- C55336

Installed on a 2006 Honda CR-V. The Honda connector is taped to the wiring at the left taillight and is a relative pain to get to. The instruction sheet shows everything except the 12vdc outlet that has to be pulled out so the plastic cover can be moved aside. That outlet just press fits into the plastic, so pull straight out. When the converter was checked with an LED tester I noticed that the stop/turn LEDs dimmed when the taillights were on. So I built a "real" tester from 1157 bulbs, sockets, and a trailer side connector to match my trailer's system. It did not work at all!! Turns out this converter needs voltage higher than 12vdc to work, so with the car running at 14vdc it was fine. Turned the car off and tested as the voltage dropped back to 12vdc. Worked at first, then one side stopped, then the other. Makes me concerned with how this will work during the daytime when the Honda ELD keeps the alternator turned off. May have to drive with lights ON to make the ELD boost the voltage. 720440

Great hitch! Easy to install and has held up great over the last year. I use it quite often to tow my 4 wheeler and tractor. Great price for a well made hitch. I would highly recommend to anyone looking for a great hitch. 714927

- C55336

Easy install. Good quality. I should have ordered an exterior enclosure so I wouldn't have hanging wires (my oversight) 936537

- C55336

I had actually discovered an etrailer video [online] which helped me figure out what I needed to purchase for a wiring harness. Once my order arrived it took me less than ten minutes to install. 914871

- C55336

Installation was fairly easy. Some panel removal was required, but that was the only difficult part. Took maybe an hour or so to install, test, and put everything back. Worked great for my occasional towing needs. 912345

- C55336

Literally a 2 minute install, plugged securely to the OEM wiring harness and worked as it should. I went with 4 stars because the adhesive to attach the converter box isn't as sticky as I'd like it to be, but this might be a positive if you ever remove it, and it's a very minor point in any case. Works exactly as advertised, buy with confidence. 909811

Overall a quality product, well made and relatively easy to install. That said, a universal comment is the passenger side bolt holes need to be tapped out because of rust and muck. Bite the bullet, make my life easy and charge me an extra $10 and include a 10 and 12mm tap to ream out the bolt holes so I don’t have to go find one somewhere else. Otherwise a great product. 898666

Installation took about 45 minutes. Completed it by myself, unhooking the 3 rubber exhaust hangers lowers muffler just enough to get to rail for installation, 889576

    Looking at the installation instructions on the Curt T-Connector Vehicle Wiring Harness, part # C55336, for your 2002 Honda CR-V, it appears that the wiring instructions will be the same for all CR-V vehicles from 2002 through 2006.

  • 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...

  • Compatibility of Curt T-Connector for 2006 Acura MDX with Wishbone Trailer Connector on Trailer
    If your trailer uses a 4-pin connector that has five wires leading to it, your trailer uses what is called a wishbone harness. The running light circuit separates at the connector (rather than separating further down the line) with one leg running down each side of the trailer. The Curt T-Connector # C55336 for the Acura MDX will work great with this type of trailer connector, as long as it is indeed a 4-pin connector. No adapter will be necessary.

  • Trailer Turn Signals and Brake Lights Do Not Work Unless 2005 Honda CR-V is Running
    If you have not detected a short or a faulty ground then the likely issue is that the factory wiring that you plugged the harness into must have some feature that does not allow the harness to be fully functional if the motor is turned off. Presumably though if the motor is off then you wouldn't be moving and the brake lights and turn signals do not have to work. But for testing purposes, that would be a little annoying. You can test the 4-Way further by following the help article...

  • Can Trailer Wiring Harness 4-Way be Routed to Outside of 2004 Honda Pilot Instead of Through Hatch
    If you remove the flooring in the storage area in your 2004 Honda Pilot to get down to bare metal you may find a grommet through which you could route the 4-Way end of a trailer wiring harness such as # C55336. If there isn't one then a hole would have to be drilled, the wiring ran, then the hole plugged and sealed. I have linked a video showing an example installation for you.

  • 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...

  • Recommended Trailer Hitch for a 2002 Acura MDX
    For your 2002 Acura MDX there are a few trailer hitch options. All of them are great and would essentially be just as good as the other. So because of that I would recommend the Curt part # 13328 if it were me as it is priced the best. I attached an install video for this for you to check out as well. If you wanted to do some towing you might be interested in etrailer ball mount kit # 989900. It comes with 2 ball mounts; one with a 3/4 inch rise or 2 inch drop and one with a 2-3/4 inch...

Hidden Hitch is now discontinued. You are also correct that the Curt hitch option for your 2006 Pilot, part # 13328, does include an additional mounting flange at its center that is not used on the other hitches.

This harness does not require you install any fuses upon installation. Check out the install video and instructions links I attached.

  • Best Ball Mount for 2005 Honda Pilot with a Curt Trailer Hitch Receiver
    All three ball mounts will fit into the Curt Trailer Hitch Receiver that you mentioned. The next thing you need to do to make sure that the trailer will pull properly behind your 2005 Honda Pilot is to measure the hitch and coupler height and to determine the correct rise or drop for your trailer. The reason you need to find all of this out is so that you can ensure that you are keeping the trailer level while towing it. To determine the hitch height you need to make sure that your Honda...

    The first thing you will want to do is consult your owners manual or with your dealership to make sure you do not exceed the roof weight capacity for your 2003 Honda Odyssey. The weight of 3 kayaks would probably be more than the weight capacity of any of the roof racks we offer for your Odyssey.
