Installation

This custom-fit T-connector plugs into your vehicle's wiring harness, which is located in your 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.


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.

This kit is perfect. It includes everything you need to complete the installation. This kit is to boost the power to your trailer lights so that they work properly. I won't buy any other kit to do this job. Thanks etrailer for your great products and awesome support.

Update to previous review. The hitch arrived on in plastic covering (no box) and quite a bit of thr associated was ripped and hardware missing. After notifying etrailer, they immediately reshipped a new hardware kit which arrived in a couple days. Can't ask for much more than that!

Very easy to do, step by step instructions. basic electrical knowledge is helpful but not necessary. Whole job took about an hour.

Install went fairly easy. There's definitely a bit of creative wire tucking involved, but nothing the every day DIYer can't handle. Worked great.

  • Brake Controller and Wiring Recommendations for a 2015 Nissan NV 3500
    Hey Thomas, thanks for reaching out! I really like the Redarc Tow-Pro Liberty Brake Controller w/ Custom Harness # RED53CR because it comes with an adapter that plugs right into your factory wiring, and the main body of the controller can be hidden virtually anywhere, just as long as you have access to the control knob. If you have the factory tow package on your 2015 Nissan NV 3500 then you'll be set to go, otherwise you'll also need the Curt Wiring # C56148 and the Universal Wiring...

  • Installation of 4-Pole Wiring Harness in 2017 Nissan NV 3500
    To install the T-Connector Vehicle Wiring Harness with 4-Pole Flat Trailer Connector # C56148 in your 2017 Nissan NV 3500 you only need to plug it into your Nissan's tail light wiring harness, which you can find in your van's rear cargo area and then wire a hot lead to the battery. I have added a cut out of the directions for you to check out, and the full installation instructions are also linked.

  • Recommended 7-Way for a 2018 Nissan NV2500
    Hey Ryan! To add a 7-way connector to your 2018 Nissan NV2500 you'll need to install two sets of wiring harnesses if you do not already have a 4-way connector installed. I have listed the parts you'll need below and how they set up. If you do not already have a 4-way connector you'll want the Curt T-Connector Vehicle Wiring Harness item # C56148. This custom-fit T-connector plugs into your Nissan's wiring harness, which is located in your rear cargo area. The connection points are inside...

  • Parts Needed to Install 7-Way on 2014 Nissan NV 2500
    There's only one way to install a 7-way on your 2014 Nissan NV 2500 and it involves installing a 4-way first like with the Curt part # C56148 which is by far the best option that is the most reliable. And then to convert it to a 7-way and install a brake controller you'd need the part # ETBC7. If you don't plan to install a brake controller you'd instead need the part # 37185. For a brake controller the Redarc Tow Pro Liberty # RED57FR is a really great option that only puts a small knob...

  • Recommended Wiring Harness for 2014 Nissan NV 3500 Passenger Van
    The Curt T-Connector Vehicle Wiring Harness with 4-Pole Flat Trailer Connector # C56148 is a confirmed fit for the Nissan NV 1500, 2500, and 3500 models between 2012 and 2020. There is not a separate fit for the cargo models from the passenger models because they utilize the same wiring. You can alternatively use # 118553 or # HM11143585 which are also confirmed to fit. These are all good options, so I recommend going with the best cost at that time of purchase.

  • What Do I Need To Tow a Car Hauler Trailer With My 2012 Nissan NV 2500?
    Yes, the Draw-Tite Max-Frame Trailer Hitch Receiver # 75715 will work for your 2012 Nissan NV 2500. Your Nissan will have a tow rating between 7000lbs and 9500lbs. You can contact Nissan for your exact tow rating by VIN number. The Draw-tite will allow for up to 7,000lbs towing and 1,125lbs of tongue weight. If you are using a weight distribution hitch the ratings are 10,000lbs towing and 1,000lbs of tongue weight. You will want to verify the weights of both your VW Passat and U-Haul...

    We do offer a 2-inch Class IV hitch for your 2016 Nissan NV 2500, the Curt # C14000. This hitch offers no-drill installation. Installation on an NV 3500 is shown in the linked video. You will also need a ball mount and hitch ball. The linked article will help you determine which ball mount you need. Use a hitch ball of the size and weight rating required by your trailer.
