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 tail lights. You will have to remove the tail light assemblies to access this harness. Once you've plugged in the T-connector, run the hot lead up to your car battery. Connect the lead to the included fuse holder, and then connect the fuse holder to the positive terminal on your battery.


Once installation is complete, the 4-way connector will be stowed in an out-of-the-way location within your trunk.


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.


Powered Tail Light Converter with Surface-Mount Technology

A tail light converter is built into this T-connector. This converter is a circuit-protected, battery-powered unit that bypasses the electrical routes that are used by a basic wiring harness. As a result, there is virtually no draw on your tail light circuits.


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.

My package for the Curt trailer wiring assembly for the 2008 Kia Sadona was missing the wire connectors, the fuse, the ring connector for the 12GA wire, the zip ties, and the two sided tape. I was not happy with it at all!

Thankyou for bringing this to our attention. Our customer service team should be reaching out to you in the near future.

The instructions for this confused me at first. I watched a video on how to install it, and followed those instructions after looking at a picture that came with the harness, it seemed to match. I then installed the blue/green wires on the left side and attempted to run the Yellow/White to the other side, but it was not long enough to reach. I then checked the written instructions and it said to do the reverse, so good thing it did not work the first time.
Installing the ballast was a bit of a problem. The picture showed it double sided taped to the back of the lens cover on the left side,but after attaching it there, I was unable to put the light back into place. I managed to move it down and squeeze it into the gap under the light, between the bumper and the frame, and then everything fit.
Once that was in place, all the rest installed easily, and worked with the boat no problems. I would blame my initial installation error on simple laziness. I hate reading instructions unless I really need to. ;)
Good product, working perfectly so far.

  • Does Trailer Wiring Harness for 2009 Kia Sedona have to be Connected to the Battery
    You will need to attach the trailer wiring harness power wire from # C56347 to the battery on your 2009 Kia Sedona. No other circuit is recommended. This is because of several factors: 1) It is not tested with any other circuit 2) Deviating from the instructions can result in a voided warranty 3) If tapped into the fuse panel you will loose some of the circuit protection If they tested it with other circuits, that would take care of 1 and 2 but 3 still remains. The issue is that the...

  • Trailer Wiring Harness for a 2011 Kia Sedona
    On the product page for wiring harness # 118410 there is a section called specs below the description. The warranty for this item is listed there and is a 1-year limited warranty. Since you are having repeated problems with the wiring harness there may be some outside factor contributing to their failure. A short circuit on the trailer wiring, corrosion on the trailer connectors, having too many lights that overdraw the harness could all be possibilities. If the vehicle just does not like...

  • Brake Controller And Brakes Recommendations For 2010 Kia Sedona And Trailer
    Thank you for the spec sheet on the axle you have on your trailer. I spoke with my contact at Dexter and they told me that you do not need to replace your axle, you can just upgrade the one you have. They told me that you have the brake mounting flange mounted on your axle so what you will want to do is add a new hub and drum, the brakes, and wiring for your trailer, and you should be good to go. The hub and drum I recommend is the etrailer.com Trailer Hub Assembly, part # AKHD-545-35-G-K....

  • Recommended Hitch and 6-Way Wiring Harness for 2010 Kia Sedona
    The recommended custom fit wiring for your 2010 Kia Sedona with a short wheel base is the Curt T-Connector Vehicle Wiring Harness with 4-Pole Flat Trailer Connector # C56347. This part provides a 4-way flat trailer connector at the back of your Kia to power your trailer's signal lights. It sounds like you have a 6-pole connection on your trailer so you will need the 6-pole adapter # 37175. You will be able to retain use of the 4 pole connector, and the mounting bracket is included as...

  • Curt Powered Taillight Converter C56347 Installation on 2014 Kia Sedona
    The black wire does indeed need to be connected to the positive battery terminal, through the supplied fuse holder. The converter box receives the signals from the taillight circuits, but it gains the voltage necessary to illuminate the trailer lights from the black power wire.

  • Parts Needed To Install 7-way Connector and Curt Echo Wireless C51180 On 2012 Kia Sedona
    I would be happy to help! The Curt T-Connector # C56347 and # C89KR you were looking at are both confirmed to fit your 2012 Kia Sedona and will both give you the 4-way connector you need. There is not major difference between the harnesses so I recommend going with the most cost effective option at the time. Moving on to adding a 7-way connector to use the Curt Echo Wireless # C51180 I recommend the # ETBC7L which was designed specifically for the Echo. The # ETBC7L will plug into your...

  • What is the Correct Trailer Wiring Harness for a 2009 Kia Sorento Without Factory Tow Package

  • Easier to Install Trailer Wiring Recommendation for 2009 Kia Sedona
    We have pretty easy to install trailer wiring kits that fit your 2009 Kia Sedona like the Tekonsha part # 118410 which does not require splicing into your vehicle wiring but we don't have a simple plug and play kit that would plug into a port at the rear of your vehicle. I attached an install video for this kit for you to check out as well.
