Quickly and easily install a 4-way trailer connector on your vehicle with this custom harness. T-connector plugs directly into existing wiring. Powered converter reduces strain on wiring system and is made using SMT to ensure superior performance.

Installation

This custom-fit T-connector plugs into your vehicle's wiring harness, which is located under the vehicle behind the spare tire. 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 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 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.

hardest part of the install is running the positive wire to the battery. adhesive pad for the converter box is kind of a joke so it would be nice if it came with additional self tapping screws

Great.. fits like OEM, just plug it in. Came with a zip ties to tuck the wiring.

  • Does The Curt T-Connector Vehicle Wiring Harness C56FR Have A Warranty?
    The Curt T-Connector Vehicle Wiring Harness with 4-Pole Flat Trailer Connector # C56FR you were looking at for your 2000 Nissan Frontier has a 1-year Limited Warranty, but we have installed multiple of the Curt harness for many different vehicles and have found them to be very reliable. I included a video review of the # C56FR for you to take a look at.

  • Parts Needed to Add 7-Way And 4-Way to 2000 Nissan Frontier
    While there isn't a plug-in option, you can get a 4-way and 7-way for your 2000 Nissan Frontier, with the 4- and 7-way plugs both available on the same unit. All you need is the following: - Curt T-Connector Vehicle Wiring Harness with 4-Pole Flat Trailer Connector # C56FR - Universal Installation Kit for Trailer Brake Controller # ETBC7 The # C56FR has the converter, and the # ETBC7 comes with the 7-way and 4-way plugs on the unit, as well as the rest of the wiring needed for the complete...

  • Trailer Wiring Harness Recommendation for a 2001 Nissan Frontier
    The Replacement OEM Tow Package Wiring Harness # 118263 is only confirmed to fit 2005-2012 Nissan Frontiers. It shouldn't work on your 2001 Nissan Frontier. For your vehicle I would have recommended the Curt Wiring Harness Part # C56FR.

  • Recommended Trailer Wiring Harness for a 2002 Nissan Frontier XE
    To add a standard 4-way wiring harness to your 2002 Nissan Frontier XE, I recommend the Curt T-Connector Vehicle Wiring Harness item # C56FR. This custom-fit T-connector plugs into your Nissan's wiring harness, which is located under the vehicle behind the spare tire. It will allow you to control the lighting functions on your utility trailer. If your utility trailer has brakes you will also need the Universal Installation Kit for Trailer Brake Controller item # ETBC7. The kit includes...

  • What Curt Hitch Is Recommended for a 2000 Nissan Frontier with 2-Doors
    It looks like you ordered the wrong hitch, the Curt Hitch part # 13841 that you referenced is designed to work on only the 4 door model 2000 Nissan Frontiers. You should have ordered the Curt Hitch part # 13831 as it is designed for the 2 door models since you said you have an extended cab. That would explain why the mounting holes aren't lining up. I attached an install video for the # 13831. To complete your towing setup you may also be interested in the etrailer.com Ball Mount kit...

  • Should Trailer Wiring Install with Trailer Hitch of 2003 Nissan Frontier
    The Curt hitch part # 13841 that fits your 2003 Nissan Frontier does not have a trailer wiring mounting bracket and neither do any of the other options we offer that fit your vehicle. The install of a hitch and trailer wiring like the # C56FR are pretty separate. It wouldn't be a situation where "well you're already half way there so may as well install it too". If you need it though you may as well just get it though.

  • Does Curt Wiring Harness for 2003 Nissan Frontier Fit 2004 Nissan Frontier
    The Nissan Frontier had a generation change between 2003 and 2004 but there are still a lot of similarities between the those two years. However, it does not appear the Curt wiring harness you looked at, part # C56FR, for the 2003 model will fit your 2004, according to Curt. Instead I would go with the Tekonsha connector, part # 118362, because it is confirmed on the 2004 Frontier. Curt does not offer a plug and play style connector for the 2004 Frontier.

  • Hitch Recommendation for a 2003 Nissan Frontier 2 Door King Cab
    Yes, the Curt Hitch part # 13831 that you referenced will fit your 2003 Nissan Frontier King Cab. Since you described your cab as a 2 door with room for a someone behind the seats that would mean you have a King Cab. A Crew Cab would mean you have 4 doors. I attached a help article on cab designs for you to check out as well. I also attached an install video for this hitch for you to check out as well.
