CURT Custom Fit Vehicle Wiring - C55502

  • Custom Fit
  • Trailer Hitch Wiring
  • 4 Flat
  • Converter
  • CURT

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


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 in rear cargo area
    • Plug in T-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


Specs:

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


Installation

This custom-fit T-connector plugs into your vehicle's wiring harness, which is located behind the driver's-side interior trim panel in your rear cargo area.


Once installation is complete, the 4-way 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.


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.

Awesome and super easy to install - fits and works perfectly in my 2012 Honda Accord and confident that the install is secure. Completely satisfied with this product. Picture shows what the CURT Hitch and T-Connector allowed me to attach to the Honda - trailer has 1720 lb weight capacity - so my reliable honda turns into a 3/4 ton pick up when needed.

I searched everywhere. I could find a harness for my car but not one with the plugs. I did not want to cut up a perfectly good harness in my car if I didn’t have to. The manufacture’s website showed they made them but none were available. From now e trailer will be my first stop.

Great product. This one utilized the reserved tow light connector on my Accord, unlike other products (they have long green wire) that need to take off both liner to access left and right signal wires, I just need to take off the left liner and every socket you need is there.

Hitch and wiring are good quality, shipping was very prompt, pricing best I found searching around... Additionally instructions were clear and complete. I am very satisfied with my purchase, and my dealings with eTrailer.

Easy to install and shipped quickly! Only disappointing thing is it disables your driver side reverse light if you connect it to the harness. I left it unplugged since my trailer doesn’t have reverse lights.

I received this receiver about 5:00 PM only three days after ordering it. I called the customer and he delivered his car at 7:00 PM. I installed the the receiver, the taillight converter and wiring, called the customer back and He picked it up ready to tow his trailer by 8:15 PM. That is amazing. Flawless fit and function. That is how to satisfy a customer.

As outlined in my hitch review I also purchased etrailer's wiring harness. Make sure you find a video on utube that shows you how to remove the back trunk panels. It would be eazy to break the plastic mounting pins. I found one that showed how in a video on attaching a wiring harness. It was a easy as one two three. Just unsnap each of the three tailights from their factory plugs, replug each of the wiring plugs on the wiring harness and replug the factory plugs into the wiring harness.additional leads. You cannot plug into the wrong one as each is unique to its own. Place a couple of tie downs on the harness to anchor it. I placed the end of the harness plug into my spare tire well, replaced the trunk panels and job done. When I need to plug in the harness to my trailer I just lift my spare tire cover, pull out the desired length to reach the traile plug and close the trunk lid.

the hitch and harness kit fit the car and the cars factory wiring harness flawlessly, much easier than i ever dreamed. shipped quickly and the price was good. I will get my next hitch from e-trailer

Watch the video on eTrailer on the install -- the included paper instructions are pretty confusing, but installation is VERY EASY. Really nice that the connector hides in the spare tire and just hangs out the trunk when you need it (rather than drilling through the floor to store the connector outside the car). No soldering, no cutting wires, just plug in and reattach your trunk panel. The first time doing this took ~15 minutes, but now that I know where everything is you could easily do this in 5 minutes.

This did not fit my 2010 Acura TSX. 95% of it fit, but I did not have a plug for the right directional (the single green wire) on my car as the instructions said. So, I ended up tapping into the directional wire in the cars wiring harness (also green) with a quick splice wire tap. That worked fine, and only held me up a bit. I don't know what model car this one does fit, but it's not a 2010 Acura TSX.



- C55502
by:

Was pretty easy to install, but the wiring in my car had a different color wire to hook to, I believe it was the one wire plug that was to hook to a green wire but mine was brown, but was not a big deal as it works.

    Both the Tow Ready T-One Wiring Harness, # 118302, and the Curt T-Connector Wiring Harness, # C55502, are essentially the same wiring harness and will provide the same function. I normally recommend the Tow Ready Harness because we sell these the most and do not have any issues with this harness, we also have a video installation of this harness for you to review.

    For a 2013 Honda Accord you should be using Curt wiring harness # C56011 or Tow Ready harness # 118420. I have included a link to the installation instructions for you to view. The connectors on the right side should be directly behind the trunk panels and trim that you have to pull out of the way just like on the drivers side.

The connectors on this harness will simply tee into the existing tail light connectors on your tail light assemblies.

  • Curt Trailer Hitch for a 2010 Acura TSX Sedan
    There seems to be some sort of mix up because trailer hitch # C11085 is designed to fit the 2011 to 2014 Acura TSX Sport Wagon, not the sedan. The proper hitch for a 2010 Acura TSX sedan is # C11496. And it does appear to stick out a bit as you can see in the video I have linked. If you plan on doing some towing the correct ball mount is # C45521. For a 1-7/8 inch ball use # 19256 and for a 2 inch ball use # 19258. For trailer wiring you can use # C55502.

This hitch has been tested to hold a maximum tongue weight of 200 lbs and a maximum trailer towing weight of 2,000 lbs when loaded. A riding lawn mower on a small trailer is probably at close to the maximum capacity of this hitch, so I recommend calculating the weights before doing this as your owners manual states 1000 lbs towing max and 100 lbs tongue weight.
