Curt Custom Fit Vehicle Wiring - C55593

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.

Installation

This custom-fit T-connector plugs into your vehicle's wiring harness, which is located behind the passenger's-side interior trim panel in your rear cargo area.


Once installation is complete, the 4-way connector will be stowed within the spare tire compartment of your cargo area.


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.

Does exactly what I wanted. Installation was a breeze. I replaced a failed box from another brand (much more expensive one too). Hopefully this one holds up longer. 136576

Ask the Experts about this Curt Custom Fit Vehicle Wiring
Do you have a question about this Custom Fit Vehicle Wiring?


  • Trailer Wiring Recommendation for a 2008 Mazda CX-7
  • As far as installation and function is concerned the Tow Ready Wiring Harness part # 118249 and the Curt Wiring Harness part # C55593 that you referenced will be the exact same. I prefer the Curt unit though because it uses a more modern style circuit board that has proven to be more reliable. Both of these are confirmed to fit your 2008 Mazda CX-7. If you need a hitch I would recommend the Draw-Tite # 75512.

  • Comparing Trailer Wiring Harnesses for a 2008 Mazda CX-7
  • Both the Curt trailer wiring harness # C55593 and Tow Ready harness # 118249 are going to fit a 2008 Mazda CX-7 that came with a factory installed towing package. If you are not sure if your CX-7 has a factory tow package then have a dealer run the vehicle VIN and they should be able to tell you how it is equipped. Both harnesses install the same way and have the same function so as far as that they are the same, just made by two different companies. The Curt harness is actually...

  • No Power on Curt Trailer Wiring Harness on a 2007 to 2012 Mazda CX-7
  • Trailer wiring harnesses # 118249 and # C55593 for the Mazda CX-7 will only fit if the vehicle came with the factory tow package. It sounds like your model did not. What you will need to add trailer wiring is a different type of harness, # 118405. It is possible that even if you ran a power wire to the battery manually and bypassed that connector it might still not work. going with harness # 118405 would be the sure thing.

  • What is the Difference Between the Tekonsha # 118249 and the Curt C55593 for a 2009 Mazda CX-7
  • If you already have the plug-in that is behind the passenger side trim panel then I recommend going with the Tekonsha # 118249 over the Curt # C55593 for your 2009 Mazda CX-7. These are essentially the same product, but we have found that the Tekonsha products tend to be the most reliable when it comes to wiring and electronics. I have attached an installation video of this wiring harness being installed on a 2008 CX-7 for you to reference. When it comes to choosing the correct Bearing...
