CURT Custom Fit Vehicle Wiring - C56051

  • Trailer Hitch Wiring
  • Custom Fit
  • 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 and passenger's-side interior trim panels 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.

The videos of hitch and wiring kit installs were easy and direct to my vehicle very easy and a fun quick project no guess work

Just like the day I installed t perfect!



by:

I was delighted with the instillation procedures and instructions. Thank you for the informative videos and wiring harness diagrams.
There is a couple of things I would like to point out. One would imagine that most of us do not have a lift or another helper. Like me all I had was jack and a jack stand which creates a whole new dynamic of an installation. With this in mind it would of been so much easier to somehow stabilizethe long thin 1/2" metal strip with welded nut on end by using a throw away metal U-Shape clamp that would hug around the metal strip holding it firmly around the protruding corrugated corrugated beam structural beam which in turn stabilizes the metal strip, holding the nut firmly over the hole would then eliminate the need for a helper. Let me make it clear on did it all my self with use of duck tape. Further while I was laying on my back under the jack I held or balanced one end of the high bar with my feet and the other end with my 2 hands and after trial and error I finally got it installed after many attempts. There is almost to different ways to install with a helper and a lift and with out a helper Also great plug and play wiring harness. It would have been nice to had a video for that but after scouring the instructions and talking with my friend I got it.



by:

Everything worked fantastic. The hitch receiver bolted up easy with the supplied installation helpers. I remember it uses a torque wrench so have one handy.
I used the plug in wire harness and that worked great. I’m an electrician and was ready to splice, solder, heat shrink - but for the forty bucks or so plug and play was the way to go.

Just received wiring harness for Honda Civic 2013. Piece of cake installation. The instructions are good and the referenced video better. Last week I installed harness on 2018 Honda CVR. Not a piece of cake. Pulled the panels out to install and could not find the module to plug in. Called etrailer and got a tech call back within three hours which I found to be great service on a Saturday afternoon. Took him about three minutes on a speaker phone to fix my problem. Works great and the price is very competitive. If you need help, these are the guys.

Man I am very very pleased with both of my purchases I have recently made. I bought a trailier hitch receiver and the car trailer wiring harness for a 08 civic. They beat all the competition price wise and product wise. Autozone want $190 for the harness and would take time to ship they had it for $30 and got it in two days hooked up within 10minutes.



by:

Product installed fairly easily. I used it to pull a [rental trailer] full of equipment back from college for the summer. Was a little harder to install that I thought but I got the job done. The wiring was very easy. I'm happy. It works and aid for itself in one pull versus renting a truck.

  • Trailer Wiring Harness Needed For 2013 Honda Civic Coupe
    I do have an option for the coupe but the Tekonsha T-One Vehicle Wiring Harness with 4-Pole Flat Trailer Connector part # 118420 fits the 2013 Honda Civic Sedan. The wiring harness needed for the 2013 Honda Civic Coupe Excluding SI and Hybrid, is the Tekonsha T-Connector Vehicle Wiring Harness with 4-Pole Flat Trailer Connector part # 118437.

  • Recommended Ball Mount and Wiring Harness for 2014 Honda Civic
    Since the trailer hitch on your 2014 Honda Civic is most likely a Class I receiver, you will need a ball mount that is compatible with Class I trailer hitches. First, for a hitch ball I recommend the Tow Ready 1-7/8" Diameter and Short Shank # 19256. This hitch ball has a gross towing weight capacity of 2,000 pounds. Choosing the correct ball mount will depend on what is needed to keep your vehicle and trailer as level as possible. For example, the Sportframe Draw Bar # 3593 is compatible...

  • Hidden Trailer Hitch Availability for a 2011 Honda Civic
    We have the EcoHitch Hidden Trailer Hitch Receiver - Custom Fit - 2" # 306-X7233 which is confirmed to fit your 2011 Civic si. If your Civic Si is a Sedan then you will also need wiring # C56051 and a ball mount kit like part # 3593 with a hitch ball like part # 19256 or # 19258. I took a look at the online owner's manual and it stated not to tow a trailer that exceeds 1,000 lbs so you will want to check your copy of the owner's manual to verify this.

  • Recommended Trailer Wiring Harness For 2008 Honda Civic Sedan
    From the photo you sent it looks like you have a Civic Sedan and the # C56051 trailer wiring harness is not designed to fit a Sedan model. It is designed to fit the Coupe only. We do have a solution for you though. I recommend the T-One Vehicle Wiring Harness, part # 118420 if your Sedan is not the Si or Hybrid model. This plugs into the connection points in the trunk area. If you have a Sedan and it is an Si or Hybrid model The harnesses we offer have to be hardwired. I recommend part...

For a ball mount part # C45521, 1-7/8 inch ball # 19256, 2 inch ball # 19258.
