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.

Fits directly to the connector in the trunk. Easy plug and play. I then popped the tab in thefloor of the trunk and ran the wires thru to under neath. All clean and hidden.
Order was on time as listed.

I have not tested yet on how well it holds up or how well it works. Time will tell.
Ill give it a 4 as of now

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.

  • What Is Required To Install Draw-Tite Class III 2 Inch Trailer Hitch # 75512 On A 2009 Mazda CX-7
    There is no drilling required when installing the Draw-Tite Class III 2 Inch Trailer Hitch # 75512 on a 2009 Mazda CX-7. You will need to lower the exhaust in the rear by removing the exhaust from the rubber hangers, but it will be connected back to the hangers after the hitch is installed. I am including links to the installation instructions of the Draw-Tite hitch and a video link that will show the hitch being installed on a 2007 Mazda CX-7. Draw-Tite says an installation by a professional...

  • Comparing Trailer Wiring Harnesses for a 2008 Mazda CX-7
    Yes, the Curt trailer wiring harness # C55593 is a confirmed 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. The Curt harness is actually rated for a little more power draw at 6 amps for running lights and 3 amps for brake/turn signals per side. The Tow Ready harness is rated for 5 amps and 2.1 amps, respectively. If...

  • Trailer Wiring Recommendation for a 2008 Mazda CX-7
    The Curt Wiring Harness part # C55593 that you referenced is a confirmed fit for your 2008 Mazda CX-7. This Curt harness has a modern style circuit board that has proven to be very reliable. If you need a hitch I would recommend the Draw-Tite # 75512.

  • Fit of Curt C55593 for a 2009 Mazda CX-7
    If you already have the plug-in that is behind the passenger side trim panel then then the Curt # C55593 is the harness for your 2009 Mazda CX-7. When it comes to choosing the correct Bearing Buddy you need to first measure the diameter of your hub bore. To ensure the best fit you need to use a digital caliper that reads to the 3rd decimal place (1.232 for example). One of the most common sizes is 1.980 for a hub bore. If you happen to have this size then you would want to go with part...

As for the Curt T-Connector Vehicle Wiring Harness, # C55593, this is the correct wiring harness for your 2009 Mazda CX-7.

  • Correct Wiring Harness for 2010 Mazda CX-7 Without Tow Package
    According to one of our friends at Curt although your CX-7 has the port on the passenger side, using part # C55593 would not provide all the lighting necessary for your trailer. Not all of the wiring connections were made. For your CX-7, part # 118405 would be the correct wiring harness to use. The T-1 would connect inline with the existing wiring behind each tail light assembly. A wire also needs to be ran under the vehicle to the engine compartment ultimately connecting to the positive...

  • Trailer Drivers Side Tail Light Not Working, All Other Lights Work
    This sounds like a ground issue. Ground problems normally show up when there is more draw on a system such as when you have the running lights on and then use another function like a turn signal or brake light. Make sure that the vehicle side and trailer side connectors are clean and free of corrosion inside and out. The main connector grounds should be attached to clean and corrosion free bare metal surfaces. The light grounds should also be attached to clean and corrosion free bare...

  • Trailer Harness Wiring Harness Recommendations for a 2011 Mazda CX-7
    The determining factor for which trailer wiring harness you need is whether or not your vehicle has the towing package. If you do not know if your vehicle has a tow package or not you would need to contact the dealer with the VIN and they could tell you. Another way to tell is to locate the connector that mates with the # C55593 harness and use a circuit tester to test each wire function. If all functions work, left and right stop and turn signals and tail light signals, then the vehicle...

  • Which Trailer Hitches, Ball Mount, Trailer Wiring, and Hitch Balls Fit a 2007 Mazda CX-7
    Yes. The Draw-Tite Trailer Hitch, # 75512, will fit on your 2007 Mazda CX-7. For many vehicles, the manufacturer will not change the chassis and/or frame platform so the same hitch can fit multiple years of the same model vehicle. I have included two links below. One is the instructions for the 75512 hitch. The other link is for all the hitches that will fit your 2007 CX-7. I also recommend adding trailer wiring to provide a 4-Way trailer connection at the rear of the vehicle. If you do...

  • No Power on Curt Trailer Wiring Harness on a 2007 to 2012 Mazda CX-7
    Trailer wiring harnesses # 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.
