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 interior trim panels in the rear cargo area. 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.


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.


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.

Fuse holder broke immediately otherwise everything works great.

It was easy putting it on my Ford Mustang 2012 V6 Premium, the only problem that I had was feeding the screws through the holes. The video installation really is a big help. I went to a local U-HAUL and asked how much would it cost to install the hitch and do my wiring they said 225. That’s when I decided to do it myself took only 2 hours it’s easier with someone helping.



by:

Seems like all of the wiring harnesses for the late model 'stangs are the same. No splicing required for the brake/tail light connections but the power wiring will require several splices. Not the end of the world but no splices for the power wiring is desirable.

1 yr update. So far so good. No wiringlighting problems with my utility trailer. No problems with my cars lightswiring either. Everything seems A-OK.



by:

This wiring harness was as easy to install as the harnesses I've installed in several other vehicles. Custom harnesses are well worth it compared to universal harnesses because the installation is faster & there's no chance of an incorrect installation & possible electrical system damage.

I dont use it often, but its been absolutely dependable



by:

Works great, easy to install. Running the wire to the battery inside the car was much easier. Already was a spare hole through the firewall.



by:
2018 Ford Mustang

Would I recommend E-Trailer the answer is yes. Fast delivery, friendly service. Instructions and videos very informative. I will admit I did not install this myself since the Mustang requires the T-harness to be run underneath the car to the battey, a lift will make life so much easier. Time to perform both hitch and harness installation two hours. Sorry no picture but Kudos to etrailer.

2nd wire harness I installed on a mustang. Fit was good, 90% of the install time was running the power line to the battery. The work in the trunk took just a few minutes.



by:

I was able to install in just over an hour. Very easy installation process and worked as claimed. The kit came with everything needed, absolutely no issues at all. I plugged the trailer into the harness and lights worked perfectly.

Excellent customer service

Easy shopping, good value and quick delivery on this product. An added bonus is a 'how to video' for installation. I highly recommend this company.

Works great would recommend getting heat shrink to keep splices protected from corrosion and weather

Easy to wire up, instructions were clear and easy to read.

Curt has always been a good product. The instructions are clear and specific without the "insert slot "a" in to "b" non-sence.

Plug and play!!

1 year later, it still works. Install was straightforward, but a time consuming job due to the nature of the job, no fault of the designer

Great kit, installs easily. The only reason I gave it 4 instead of 5 stars is that I do not like how it is set up to hang out of the trunk when in use.

  • Recommended Trailer Hitch for 1-1/4" Bike Rack on 2013 Ford Mustang Convertible
    The Curt Trailer Hitch Receiver part # C11210 which is a fit for a 2013 Ford Mustang Convertible does not require a stability strap, just the bike rack will be fine. It has a class I rating with 1-1/4" opening so any bike rack with a 1-1/4" shank will work great. The trailer hitch features a bolt-on install. Please note, you won't need any sort of wiring harness if you're just using the trailer hitch for a bike rack, that's only for towing and in which case you could use the Curt T-Connector...

  • Trailer Hitch and Wiring Recommendation for 2010 Ford Mustang
    The Curt hitch part # C11048 is a confirmed fit for your 2010 Ford Mustang GT and will be a great hitch to use. For trailer wiring you then would want the part # C56088 which is a confirmed fit too. I attached install videos for both these products. For a ball mount you then would want the part # C45572.

  • Class I Trailer Hitch Availability for 2015 Ford Mustang V6
    For the 2015 Ford Mustang only light-duty 1-1/4-inch Class I hitches are made. This is because the car's frame structure cannot support the higher weight capacity of a Class II hitch. There would be no value is using a higher-rated hitch (nor in having one made) since the car itself cannot support even the Class I rating of 200-lbs tongue weight and 2000-lbs gross trailer weight. According to the online Ford towing guide the V6 Mustang has a 1000-lb maximum trailer weight capacity. Your...
