CURT Custom Fit Vehicle Wiring - C56039

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

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 in rear cargo area
    • 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: 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 interior trim panel in your rear cargo area.


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.

etrailer made it so easy to install the hitch and wiring harness for my Mitsubishi. I would have probably paid someone else to install these products for me, but the videos and installation instructions provided were made specifically for my vehicle; which made installation a cinch!
It's a professional looking install with quality products, and ordering and shipping were a breeze! I'm very satisfied.

The wiring harness was easy to find, easy to buy, and easy to install with the video. One year later, still works like it was new. No complaints. Ill buy from etrailer again!

2007 Mitsubishi Endeavor

I ordered this Curt hitch & wiring kit for our 2007 Endeavor mainly because I’ve purchased other Curt products before & was very pleased with their products. Build quality is first rate, as with all other Curt products I’ve purchased. The set up couldn’t be simpler as they’ve thought of everything in their design & engineering so that it’s pretty much a “plug & play” process. In addition, the directions are clear & concise. Great product, Made in USA! Great price, thanks to etrailer.com!



by:

The hitch and wiring mounted easily and looks terrific! The instructional videos were clear, concise, and provided all the information I needed. Best of all, they matched my actual experience, so the actual install went just as expected. I have a hitch that the pros couldn't have installed better. Thanks, etrailer!



by:

Fit perfectly.



by:

This assembly installed exactly as advertised. I was a bit skeptical at first after spending at least an hour on previous wire harness installations from other vendors. I will definitely order from etrailer again.

Shipped quickly. Everything fit like a glove... not OJ's... Wiring was quick and easy. Towed a 14ft trailer loaded with a 2500 lb swing set 600 miles. Nothing loosened. Held up great. Good experience.



by:

From beginning to end of my order I was completely satisfied. The customer service that I received was awesome. It's so refreshing to speak with someone who has the knowledge required to do a job well. The rep I spoke to was more than helpful. Knowledgeable and extremely patient in answering all my questions and the call was then followed up by a personal email. The product I received was exactly as described and yes it was the right one the first time.... easy to install and works perfectly. Thank you etrailer.com I will definitely be using your services again

If it was any easier to install this, I could have had my 4 year old granddaughter put it in. Shipping was 2 days. So fast. Etrailer personnel are the most courteous, helpful people I have seen in a long time. I am a customer for life.Thank you very much.

  • How to Install Trailer Wiring on a 2004 Mitsubishi Endeavor Pulling a Boat Trailer with a 5-Way
    Yes, the fifth wire on your boat trailer is most likely a reverse lock-out solenoid for the surge brakes so that you can reverse your trailer without the brakes activating. I would recommend you install this Curt T-Connector # C56039 on your 2004 Mitsubishi Endeavor (instructions attached) and then cut the 4-way off of the harness and then wire up a Hopkins Endurance 5-Way Flat Trailer Connector # HM47900 by function to the wires that are now exposed from the # C56039 to the # HM47900....

  • Recommended Trailer Hitch Receiver For A 2007 Mitsubishi Endeavor
    Yes, we currently have one trailer hitch confirmed to fit your 2007 Mitsubishi Endeavor, the Curt Trailer Hitch Receiver # 13113. This trailer hitch has a 2" receiver tube opening, which is the most common for towing and other hitch accessories (bike racks, cargo carriers, etc.). It has a 3,500lb gross trailer weight (GTW) capacity and 350lb tongue weight (TW) capacity. You'll want to refer to your owner's manual to ensure that the vehicle matches the capacities of the hitch, if not you'll...

  • Boat Trailer Lights Not Working when Connected to a 2011 Mitsubishi Endeavor
    The first thing to check for a factory fuse that is missing or blown. Check the vehicle owner's manual for any and all fuses related to the tow package wiring so you can check them. If all the fuses are good and in their proper places, then you will need to test the harness to determine if it is the problem. Use a circuit tester such as # PTW2993. Test the wiring going into the converter from the vehicle. If there is no power, there then the issue is a fuse or a wiring issue on the vehicle...

  • Recommended Trailer Brake Controller For 2004 Mitsubishi Endeavor
    I have included a video of a trailer brake controller being installed in a different vehicle, but we have not had the chance to install one in a 2004 Mitsubishi Endeavor. If you do not already have a 7-way connector installed, you will need to install one by first installing a 4-way connector # C56039. With a 4-way connector installed you will then need to install the # ETBC7 which will give you wiring needed to power trailer brakes. This will allow you to use a traditional trailer brake...

When you are ready to tow, you simply feed the connector over the door threshold and shut the rear hatch door. Be sure you keep the wires away from the hinge so the wires do not pinch.

  • Parts Needed to Add 7-Way to 2004 Mitsubishi Endeavor With 4-Way
    Certainly; since you already have a 4-way like the Curt # C56039 on your 2004 Mitsubishi Endeavor, you can add a 7-way with one kit: - Universal Installation Kit for Trailer Brake Controller # ETBC7 The 4-flat will activate your trailer's lighting functions, and you'll then plug the 4-way into the 7-way that comes with the # ETBC7, which also gives you the wiring, circuit breakers, and rest of the hardware needed for installation.

    The connector on the Curt # C56039 T-Connector would indeed plug into the trailer connector plug located in the cargo area, under the carpet next to the driver's side wheel well as shown in the photo. Just to be sure, I contacted our representative at Curt, who assured me that the # C56039 trailer wiring harness is compatible with all models of the 2004 Mitsubishi Endeavor. If you don't yet have a hitch, I'd recommend the Curt Class III # 13569. This hitch has a bolt-on installation and...

  • Do I Need To Lower My Muffler To Install This Hitch?
    Hello, We have the Curt Trailer Hitch Receiver # 13113. It requires no drilling but you will need to temporarily lower the exhaust to properly and completely install the hitch. This Curt hitch is also rated for use with a weight distribution system. If this will be for towing a trailer you will need a wiring harness like the Curt T-Connector Vehicle Wiring Harness # C56039. This will power the trailers lights and keep you safe and legal. And a Curt Towing Starter Kit for 2" Hitches - 2"...

  • Where Does the White Wire of the Curt Wiring Harness # C56039 Go on a 2011 Mitsubishi Endeavor
    The white wire you referenced actually needs to get run to a clean metal surface on the body of your 2011 Mitsubishi Endeavor with the included self tapping bolt through the ring terminal. This grounds the converter and allows it to function properly.
