CURT Custom Fit Vehicle Wiring - C56127

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

Quickly and easily install a 4-way trailer connector on your vehicle with this custom harness. T-connector plugs directly into existing wiring. Powered converter reduces strain on wiring system and 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

  • Connects quickly and easily
    • Locate connection points behind tail lights
    • Plug in T-connector
    • Run hot lead to car battery
  • Includes a tail light converter to ensure that your vehicle's wiring matches that of your trailer
    • Powered module connects directly to battery to avoid overloading vehicle's electrical system
  • 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

    • Tail lights: 6 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 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 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.


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.

Mitsubishi Outlander

Welded up a hitch for my outlander sport and after I got it all bolted on realized there was no wiring. After looking on the internet for a few days I had given up, luckily I found etrailer. 98% of my cars manufactured are cvt’s so you can’t tow. Mine happens to be a Manuel, I talked to the dealer and he said they’ve never made this car in manual. I was very great full to find etrailer and that they somehow managed to make things work!

The light wiring harness arrived in a few days. It came with good directions and I installed it in a couple of hours. The biggest challenge was running the hot wire up to the battery. But it plugged in to the existing wiring behind the taillights. Fairly easy to do yourself.

after a year of use i have nothing but good things to say about the hitch and the wiring harness. best money i have spent on a hitch system, well done. thanks for touching base .



by:

After purchasing the wire harness from etrailer I immediately went out to put it on my car. I was amazed at how easy it was to do. Every instruction was there with pictures and I was able to put the wire harness on with ease. The hardest part was running the power cord to thff we battery. Everything else was very easy. Thank you

I had a mechanic install this.
I'm
never comfortable taking panels off the interior.
I'll rebuild a suspension, remove an engine, and replace an exhaust, but I don't fool with taking the interior apart.

The instructions that came with the wiring were actually quite good. No problem at all with installation. Very Happy!!!! Love Etrailer. And shipping was super fast.

  • Comparing Trailer Wiring Options for a 2008 to 2012 Mitsubishi Lancer
    Many trailer wiring harnesses are vehicle specific so I would need to know the year, make, model, and trim level of the vehicle to recommend the best wiring harness. The Curt hitch you referenced, # 11479 is designed to fit a 2008 Mitsubishi Lancer except the Evolution and 2009 to 2012 Mitsubishi Lancer except Evolution, Ralliart, and Dual Exhaust models. For a 2008 to 2011, we only have the # 119178KIT available. For a 2012 you can use the # C56127. In this case the Curt harness, # C56127,...

  • Parts Needed To Tow a Trailer With a 2019 Mitsubishi Outlander Sport
    In order to tow a trailer with a 2019 Mitsubishi Outlander Sport you'll need a trailer hitch, trailer wiring harness, and ball mount/hitch ball. I have great options for all of these parts and will attach them below. In regards to the wiring, most smaller trailers only require a standard 4-way so this is likely what you will need. The 7-way is only required when the trailer has brakes. Curt Trailer Hitch Receiver part # C13079 Curt T-Connector Vehicle Wiring Harness part # C56127 (With...

If you plan on doing some towing you might be interested in etrailer ball mount kit # 989900. It comes with 2 ball mounts; one with a 3/4 inch rise or 2 inch drop and one with a 2-3/4 inch rise or 4 inch drop.

  • Will Trailer Hitch Void the Warranty for a 2017 Mitsubishi Outlander Sport
