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 tail lights. You will have to remove the tail light assemblies 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 rear 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.

I got everything on time and it’s working good and also high quality

Order arrived when on time as promised and was easy to install with no difficulties. Satisfied customer!

This harness made it easy to connect with the factory brake light system. The only thing I'd say is take your time carefully running the +battery lead. I was able to tie it up along with the fuel and A/C lines on the inside of the frame rail and come up into the underhood area. Everything is still working one year later.



by:

Thank you so much!! Great service! They called to make sure that there were no security issues before allowing the purchase. Items arrived MUCH faster than expected! Installed hardware with ease with all supplied new bolts. The electrical package was all pretty much plug and play and easy to install. I wish it came with a mounting bracket for the trailer plug to make it stationary. My only other critique is that the "etrailer.com" sticker is upside down. Great job everyone! Thanks!!

  • Solution for Needing to Power Trailer Wiring Converter Box and 12 Volt Accessory Circuit of 7-Way
    You would not be able to share the power wire of the Curt T-Connector Vehicle Wiring Harness # C56342 for also powering the 12 volt accessory of a 7-way like the part # 37185. But I have a similar solution that would be just as easy. Instead you'd want to run the double bonded wire part # 10-2-1 (sold by the foot) to the battery of the vehicle and then attach both leads to the battery post and you'll essentially have run "one" wire to power both the converter of the 4-way and the 12 volt...

  • Trailer Wiring Harness Recommendation for 2014 Nissan Quest
    Not all vehicles can handle the additional amperage draw of the trailer taillights on the vehicle taillight circuits. Those vehicles need setup that draws power from the battery. Some vehicles have higher rated circuits that can handle this, and others need to have the power drawn straight from the battery to protect the taillight circuits. For your 2014 Nissan Quest SV you need to install a harness that draws power from the battery to protect the taillight circuits. For that you would...

  • Towing Package For A 2016 Nissan Quest
    The etrailer Trailer Hitch Receiver - Custom Fit # e98KR has the heaviest rating of the hitches that are confirmed to fit your 2016 Nissan Quest. The trailer hitch has a bolt-on installation with no welding required. It has a matte black powder coat finish which is over a protective base coat that offers a superior rust resistance. The trailer hitch has a maximum gross trailer weight up to 3,500 pounds and has a maximum tongue weight up to 300 pounds. I would recommend checking the...

  • Is It Possible To Pull A 4x8 Utility Trailer With A 2011 Nissan Quest?
    Hello Jose. It is possible to tow a small trailer with a 2011 Nissan Quest. I recommend that you use the etrailer Class 3 Hitch # e98KR. This has a 2" receiver and is rated for towing 3,500 lbs. Your Nissan Quest is also rated for towing 3,500 lbs, so as long as the gross trailer weight does not exceed 3,500 lbs you will be just fine. You will also need the Curt T-Connector # C56342 for your trailer lights. I also suggest that you use the Ball Mount Kit # C45534 which will come with everything...

  • More Reliable Trailer Wiring Harness for 2016 Nissan Quest
    Sounds like the harness is getting overdrawn by your trailer wiring which is shorting it out and causing it to fail and then also causing the lights on the vehicle to stay on. Does the trailer have a lot of lights on it? We don't have the best luck with Curt trailer wiring kits so I would recommend the Hopkins kit # HM11143674 instead for your 2016 Nissan Quest.

  • How Long is the Power Wire with Curt Trailer Wiring Harness for a 2012 Nissan Quest
    The Curt trailer wiring harness # C56342 comes with a wiring kit that includes a 20 foot length of 12 gauge wire to connect to the battery on your 2012 Nissan Quest. The other option is to use harness # 118547 that does not require a power wire ran from the front to the back of the vehicle. I have linked instructions for you to view.

  • Trailer Wiring Harness Converters Keep Shorting Out on a 2014 Nissan Quest
    Water getting in the 4-Way connector would not cause it to short out but if water somehow got into the converter box then that could do it. But it is unlikely for that to happen twice. The more likely cause of the problem is a short on the trailer that is back feeding to the converter causing it to short out. In that regard the converter box is doing its job and protecting the vehicle wiring from the short. Inspect the trailer wiring and fix any pinched or damaged wires. If there is wiring...

  • Correct Trailer Hitch and Trailer Wiring Harness for 2017 Nissan Quest
    According to Curt, the # C13900 is a fit for the Nissan Frontier and the small Nissan Pickup that predated it but they don't list the Quest as a fit. I'd recommend using the Curt # C13078 Class III hitch which is specifically designed for your 2017 Quest. If you'll be using the hitch for towing purposes, you'll also need the # C56342 trailer wiring harness, a ball mount like # 40346 (use in the rise position) and a 1-7/8 inch ball like # 19260 or a 2 inch ball like # C40004. You'd also...

  • Trailer Hitch for 2017 Nissan Quest
