Installation

This custom-fit T-connector plugs into your vehicle's wiring harness, which is located in your rear cargo area. To access this harness you will have to remove the rear scuff panel and some interior trim.


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.

As other reviewers have pointed out there is a chance the connector wiring is backwards (mine was). If you see this behavior yours could be wired backwards:

-Left turn -- both tail lights flash
-Right turn -- Nothing
-Hazard -- both tail lights flash
-Brakes -- Nothing
-Running lights -- both tail lights lit

I fixed the wiring problem and now the product works as expected. I would have rated this 4 to 5 stars had the wiring been correct.

Great customer service from etrailer.com. however part quality did not meet my expectations. They had installed the wiring in each of the white connectors backwards (ie red,yellow,brown,white was white,brown,yellow,red). Same with the green side. I had to remove them and switch them around. Maybe they just laid them in their jig upside down. It works fine now and that is what matters.

Custom made and fit just perfect for my 2012 Kia Forte 5. Took a little while to install due to having to remove some interior trim and re install. Actually took longer than the hitch itself! But it worked as it is supposed to and was not hard to do. Just follow the directions! Thanks again Madison P.

Ask the Experts about this CURT Custom Fit Vehicle Wiring

  • Are Taillight Converter Boxes Waterproof
    The converter use on # C56131 is designed to be water resistant, but it isn't what I'd call waterproof. If it was submerged, water would likely enter the case. I've talked to folks who have gone this route, and they have sealed the converter box seams and wire entry/exit points with silicone caulk, which seems to do the trick. If its possible to mount the box in a spot where it would be somewhat protected from the elements, I'd recommend doing that as well.

  • Trailer Wiring Harness for 2011 Kia Sorento
    The correct Curt trailer taillight wiring harness will depend on if your Sorento is equipped with the factory tow package. If it doesn't have the tow package, use # C56328, unless it's the SX model, which would use the # C59236. If it does have the tow package, it would use # C56332. The Curt # C56131 you'd looked at is a fit for the Kia Forte, and wouldn't work on your Sorento. I've linked to some installation videos that you might find helpful.
