Installation

This custom-fit T-connector plugs into your vehicle's wiring harness, which is located in your rear cargo area. You will have to remove the floor coverings and the rear scuff panel 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.

Easy website and great coordination with parts that need to go together. Simple easy to follow instructions and it works as necessary. I've purchased here before and I am coming back when I need another hitch and harness.

Super easy to install. Thanks to etrailer for posting how to videos the product went in exactly how the video showed. The average joe will have no trouble installing this product.



by:

Quick shipping, good instructions using the video, straight forward installation, works great - especially with having its own power direct from the battery. First time my trailer lights have had normal brightness and are dependable. Thanks for a great product.



by:

I was amazed at how simple it turned out to be to use the harness I bought. The video instructions worked as explained, and the trailer lights worked correctly the first time I plugged in my trailer to the new harness.

Cant get much done without a 2-inch ball and thanks to the swarms of agents/ servants of sandusky, trailer light wiring.

Thank you for offering a plug in setup VERY easy to install even for a guy who doesn't like low voltage.

You cant even rent a open trailer without wiring, just put it in.



by:

I have owned this wiring harness for about a year now. The install was very straight forward and easy with the provided videos. I have only used the wiring harness a couple of times but it has worked when I needed it.



by:
2012 Toyota Prius c

With the video online, it took me less than a half hour. Be careful removing the seat cover over the battery, since the clips on mine broke and I had to get new ones (for just a couple dollars). Also, be careful not to lose the washer on the battery.



by:
2012 Toyota Prius c

Easy to install and wire lengths are perfect. Hit the side pannel with a punch helps a lot before trying to screw the self tap screw. The 2 faces tape is a good idea, but couldn't find a place were it could fit well. I used tie-wrap to mount it.



by:
2012 Toyota Prius

Great to have a company which distributes the Curt T-Connector to likely a niche market - the Toyota Prius C.



by:
2015 Toyota Prius c

This was amazing! I am intimidated by anything electrical but this was quick and simple. Everything I needed was included and it went exactly as shown in the instructions. The video made it easy and boosted my confidence.



by:

Easy to install, easier than the hitch actually. Works well but the video didn’t mention bolting in the negative battery back in, so if don’t your car won’t start up.



by:

It works well when it works. These are super easy to install / replace. Annoying that mine failed just outside of warranty.



by:

Adhesive for unit was completely dried out / old stock. Otherwise good product with Toyota specific T plugs. Matching cable tie adhesive pads would help, but gaffers tape worked OK.

  • Recommended Trailer Hitch for a 2014 Toyota Prius C
    In the owners manual Toyota does not recommend towing a trailer with your 2014 Toyota Prius C, or even installing a hitch. However, if you choose to do so, I can recommend the parts you will need. We offer two hitches for your 2014 Toyota Prius C, the Class I Curt Hitch # C11484 and the Class I Draw-Tite Hitch # 24889. Both have a towing capacity of 2,000 lbs GTW and 200 lbs TW. However, be sure to consult your owner's manual or contact your Toyota Dealer to see how much GTW and TW your...

  • Recommended Ball Mounts Compatible with 2" EcoHitch Hidden Receiver # 306-X7194 On a 2015 Prius c
    The EcoHitch Hidden Trailer Hitch Receiver # 306-X7194 for your 2015 Toyota Prius c has a 2" receiver that we measured to have a hitch height of 11-1/2". With this you can use either a fixed ball mount like the Curt # C45100 that has a 6" rise which would fit on a trailer with a hitch height near 15-1/2". You will need either a 1-7/8" # C40002 or 2" # 40038 ball. If you intend to pull different trailers that can have different hitch heights an Adjustable Ball Mount # BWTS10038B will allow...

  • Easiest To Install Trailer Wiring Harness for a 2014 Toyota Prius C
    I do have a very simple and easy to use option for your 2014 Toyota Prius C but I have never heard of any such thing as a wireless trailer wiring harness before. Therefore, the only way to tow a trailer with your Prius is to install a wired trailer wiring harness. I recommend the Curt T-Connector Vehicle Wiring Harness part # C56275 because it is plug and play which means no cutting or splicing is required. This will be the easiest to install and least invasion trailer wiring harness available...

  • Recommended Trailer Hitch Receiver and Vehicle Wiring Harness For a 2013 Toyota Prius C?
    I recommend the EcoHitch Hidden Trailer Hitch Receiver # 306-X7194 for your 2013 Toyota Prius C. The Curt # C11276 you found will not fit your particular Prius C. The EcoHitch has the larger 2" receiver allowing for a much larger selection of hitch mounted accessories. It is best to install the Curt T-Connector Vehicle Wiring Harness # C56275 when you install the receiver. This will give you a 4-way flat connector. This is the most common connector used on small trailers you might tow....

The OnRamp is capable of supporting bikes with a weight up to 66lbs. It is capable of supporting 2 bikes as you need a rack that uses a frame mount. Your Bulls Lucha e-bike has fenders that will not work on a single bike bike rack that clamps the bike in place by the wheels and tires. The OnRamp also includes a 51" ramp that will make loading your...
