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 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 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.

The sales order experience was nothing short of fantastic. The salesman was polite and very knowledgeable. I took the trailer hitch and wiring to a local shop and was surprised at how reasonable they were to have it installed. The only thing missing was a mounting bracket to hold the wiring harness and that was provided by the installer to make it look more professional.

For that professional look I recommend using brackets part # 18144 and part # C57202 together to attach the harness to.

The components worked as indicated. The plug in adapters eliminated splicing and/or soldering. The installation description and videos were very helpful. The 2 sided adhesive foam pad is not robust.

Item fit my vehicle with no issues. All required parts included. I would suggest purchasing better wire connections. Otherwise, 25 minute install. Works great. Fast shipping.

  • 4-Way Vehicle Wiring Harness Compatible With a 2011 Infiniti EX35
    Currently the Hopkins Active Tail Light Converter # 46255 is the only 4-way wiring which is confirmed to work on your 2011 Infiniti EX35. Curt does not have a wiring kit which will plug and play into your tail lights as the Kit # C56074 is for certain model year Infiniti FX's and the Kit # C56033 fits some G series Infiniti's and Nissan Rogue's.

  • Installation Time for the Curt Wiring Harness # C56074 on a 2009 Infiniti FX35
    Curt has listed an installation time of the wiring harness # C56074 as 30 minutes for the professional installer. I spoke to my installer and he said for a novice you should expect 1 hour and a half at the very least. I have linked the instructions to this page for your convenience. I do want to let you know that the Curt Hitch # 13554 will require you to use a stabilization strap # 18050 with any non-trailer loads (bike racks, cargo carriers, etc.) which is why I instead recommend the...

  • Troubleshooting # C56074 Trailer Wiring Harness Installed on 2012 Infiniti FX35
    Is it the vehicle lights, or the trailer lights that remain on when the vehicle is shut off? Does the trailer have LED lamps, or incandescent? If it's the trailer lamps remaining on and the trailer has LED lamps, it is normal for the trailer lights on vehicles using some of the Curt powered converters to have a slight 'glow' (but NOT be fully illuminated) when the vehicle is turned off. Not enough power is being drawn to drain a car battery, but the trailer can certainly be unplugged if...

  • Hitch and Trailer Wiring Recommendation for a 2011 Infiniti FX35
    For your 2011 Infiniti FX35 the Curt Hitch part # 13554 is the correct hitch. For trailer wiring you would also need the Curt Harness part # C56074 since it is not included with the hitch. I attached an install video for the hitch for you to check out as well. If you wanted to do some towing you might be interested in etrailer ball mount kit # 989900. It comes with 2 ball mounts; one with a 3/4 inch rise or 2 inch drop and one with a 2-3/4 inch rise or 4 inch drop. It also includes a...

  • Converting 4-Way on 2010 Infiniti FX50 to European 7-Pin
    To convert the Vehicle Wiring Harness with 4-Pole Flat Trailer Connector # C56074 to a European 7-way you need to first install this connector in your 2010 Infiniti FX50. After that, cut off its 4-way and you will need to use Converter # 118158; connect its green, yellow and white wires to the matching color wires on the Harness. The brown wire for the tail lights will not connect to the converter but you need to run a jumper wire to the brown wire to attach to the two pins of the Euro...

  • Recommended Wiring Harness for 2013 Infiniti FX35
    The Curt T-Connector Vehicle Wiring Harness with 4-Pole Flat Trailer Connector # C56281 is unfortunately not a fit for your 2013 Infinity FX35. You must have a carry over model because the FX35 was changed when they added horsepower to create the FX37. The correct wiring harness I recommend for you will be the Curt T-Connector Vehicle Wiring Harness with 4-Pole Flat Trailer Connector # C56074 which is compatible with the 2012 FX35 and the 2013 FX37 models as well as some others. I've...
