CURT Custom Fit Vehicle Wiring - C55529

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

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.


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 point behind rear bumper
    • 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


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 rear bumper, on the passenger's side.


Once installation is complete, the 4-way 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 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.

Looked just like the old one. Snapped right into the connector on my 2006 Kia. Very satisfied.

Snapped right into place. Perfect fit on my 2006 Kia Sportage.

Plug & play
It came with my hitch, very
quick shipping.
The hardest part was finding my car's socket and getting the oem cap off, after that it went fine.
I suggest getting the little plug in tester that fits the flat 4 plug, it makes quick work of verifying all is good to go and retesting occasionally thereafter before hooking up a trailer.

A year on and no problems, works as should.Tip for free, keep the connectors greased up with dielectric grease to prevent corrosion.

when i go to get the tailor I'll be all set with the wright parts

2009 Kia Sportage

Not sure, the last one shorted Outland had to drive 2 hours without brake lights



by:

Easy installation. Perfect fit. The leads are quite long and you have to be careful that they are wrapped up out of the way when not in use may otherwise they may drag on the ground and get damaged. I'm not sure exactly what happened but this worked fine for 6 or 7 months. Now the left side trailer lights don't work properly. The Brake/turn signal light works as the tail light and the tail light is the brake/turn signal. I did damage the plug and am in the process of trouble shooting the problem. I plan on cutting off the damaged portion and splicing in an new plug. If this corrects the problem then I may replace the unit with a new one.

It has been almost 3 years and it is still working great.

Couldn't be any easier to install.

2005 Kia Sportage

The hitch was the correct one for the car, and the cable harness and receiver was correct also. Delivery was extremely fast: ordered on Wednesday, delivered on Friday.
All necessary parts were included, including instructions for torquing down the bolts.
I installed the hitch, 'without a hitch' on Saturday. It took about an hour, since I don't have any air tools.
All in all, I am very satisfied, and would recommend your company.
Thank you.

Very bad..one of the 4-pole ended uprising the one metal connector..I was refused a free replacement ...not very satisfied at all...

This wiring kit was exactly what I needed, and was SO EASY to find, purchase, and install. It came with pictures on the instructions, as well as a tutorial video on the product page. So convenient!



by:

Nice product, installed in literally 10 minutes.
Called my local NAPA, O Rielly and AutoZone first to try to get one same day but no one had one. etrailer.com had it in stock and cost was less than the others quoted me even with 2 day air I paid to have it by the weekend.



by:

Plug and Play easy just had to add some additional Alienware as the double back adhesive and zip ties won't last long in Arizona.



by:
2007 Kia Sportage

Very easy to install and works great. I wish it came with longer zip ties as the ones in the kit are way too short, but that's an easy fix.

  • Trailer Wiring Recommendation for a 2009 Kia Sportage
    For your 2009 Kia Sportage a wiring kit with circuit protection is recommended. If you were to install a harness without the circuit protection like the Draw-Tite Wiring # 18252 you would most likely blow some fuses as well as potentially damage your tail light circuits. Even with your LED taillights. For an easy to install wiring harness confirmed to fit your vehicle I would recommend the Curt Wiring Harness part # C55529. This plugs into your vehicle's wiring harness, which is located...

  • Trailer Wiring Harness for a 2017 Kia Sportage
    For your 2017 Kia Sportage you can use Tekonsha trailer wiring harness # 118698. It is designed to fit the 2017 to 2018 Kia Sportage. I have included a link to a video showing an example installation for you. I recommend the Tekonsha wiring harnesses more than others because they work well and are more reliable.

  • Comparing the Trailer Wiring Harnesses for a 2010 Kia Sportage V6
    The best trailer wiring harness for a 2010 Kia Sportage is the T-One Vehicle Wiring Harness part # 118401 because it has a fully epoxied converter box which not only works to keep out water but also works to help hold the wires on the circuit board which is the most common failure point for a trailer wiring harness. The Curt T-Connector Vehicle Wiring Harness part # C55529 also has an epoxied converter box but not to the same level as the T-One Vehicle Wiring Harness. I would concur that...

  • Trailer Turn Signals Do Not Work With Curt Custom Fit Vehicle Wiring # C55529 for 2007 Kia Sportage
    Thank you for your recent purchase which included Curt Custom Fit Vehicle Wiring Harness # C55529. The best way to troubleshoot this or any other trailer wiring harness is to use a circuit tester such as the # PTW2993 from Draw-Tite. A tester will allow you to verify that the proper signals are both entering and exiting the converter module. Since your trailer's brake and taillights are working properly you can first focus on the green and yellow wires on the left-hand (input) side of...

  • Is There Any Difference Between Curt C55529 and Tekonsha 111401 For 2008 Kia Sportage V6
    Both the Curt # C55529 and the Tekonsha # 118401 are designed to fit on your 2008 Kia Sportage with the V6 engine; they both have the same functions and provide you with a 4 way plug for towing a trailer with your Sportage. The only difference aside from the manufacturer is that the Curt # C55529 can handle tail lights on the trailer that draw a bit more amperage (3 amps) compared to the Tekonsha # 118401 (2.1 amps); this would be especially helpful when towing a trailer with a lot of lights...

    As long as your 2008 Kia Sportage is the 6-cylinder model, the Curt T-Connector Vehicle Wiring Harness # C55529 referenced in your question is a confirmed fit.

  • Recommended Vehicle Wiring Harness For 2010 Kia Sportage That Current Harness Got Melted
    I am sorry to hear that! Based on how damaged the harness you have installed on your 2010 Kia Sportage V6 is due to the heat from the exhaust you would benefit from replacing the entire harness, as the damage in your first picture is pretty severe. I recommend going with the Tekonsha # 118401 and wrapping the harness with some exhaust wrap which you can pick up from your local auto parts store. In addition to that I recommend trying to keep the harness as far away from the exhaust as...
