If your vehicle is not equipped with wiring for towing a trailer, CURT custom wiring is the ideal solution. A custom wiring harness -- also called a T-connector -- is a simple, plug-and-play electrical device that plugs into your automotive electric system and provides a standard, universal trailer wiring connection. This is done using two or more vehicle-specific, OEM-compatible connectors to plug into the taillight assembly, eliminating the need for cutting, splicing and soldering during installation. Custom wiring harnesses are made vehicle-specific, and while they are not available for all vehicles, they do offer one of the fastest, easiest and most secure ways to wire a vehicle for towing. This particular plug-in harness provides a 4-way flat connector socket and is designed to be a custom wiring harness to fit certain years of the Infiniti G25, G35, G37 and Q60 and Nissan Rogue (to verify your vehicle compatibility, see application info). It comes with all necessary wiring components to establish a reliable trailer wiring connection, as well as a dust cover to keep the connector clean when not in use. You have a picture in mind of your next destination -- maybe it's the boat landing at your favorite fishing spot, maybe it's a campsite that overlooks one of nature's masterpieces, or maybe it's the next big jobsite. However, turning that picture into a reality takes more than just daydreaming. It takes a solid connection and the right amount of power. CURT custom wiring is made with some of the most sophisticated technology in the industry and is designed to install with ease, giving you a long-lasting electrical connection for your towing hitch setup.

The CURT Custom Wiring, 4-Way Flat, Select Infiniti G25, G35, G37, Q60, Nissan Rogue Trailer Connector Kit (Part #BKDK56033) Typical installation time is 30-60 minutes. Basic hand tools are typically all you need.
Yes, the Curt 56033 is designed for Infiniti G35 sedans. It is also compatible with Infiniti G25 and G37 sedans, and Nissan Rogue vehicles. The harness connects to the taillight wiring connectors located behind the taillight housing inside the trunk.
Yes, the Curt 56033 custom wiring harness is compatible with Nissan Rogue vehicles. The installation process for the Rogue differs slightly from Infiniti models: you will remove the rear scuff panel, storage covers and floor coverings from the trunk to access the taillight wiring connectors.
The Curt 56033 has a Signal Circuits rating of 3.0 amps per side and a Tail/Running Circuits rating of 6.0 amps total. The battery connection must be fuse-protected with a 10-amp maximum fuse. Do not exceed the product rating or your tow vehicle's lamp load rating, whichever is lower, as this can cause loss of warranty, overheating and potential fire.
You will need a ratchet, 10mm socket, Phillips screwdriver, flat blade screwdriver, and panel trim removal tool. The harness includes a provided screw and ring terminal for grounding, double-sided tape for the converter box, and a 4-flat dust cover.
Yes, you must disconnect the negative battery terminal before beginning installation. This is the first step in the installation process. Reconnect the negative battery terminal only after all other installation steps are complete and all items removed during installation have been reinstalled.
On the driver side, insert the custom wiring harness end with the yellow wire between the separated vehicle taillight connectors. Make sure the connectors are fully inserted with locking tabs in place. Then route the harness end with the green wire to the passenger side and repeat the process using the green wire end. Take care not to damage the locking tabs when separating the original connectors.
Not necessarily. First, locate a suitable grounding point near the taillight connector, such as an existing screw with nut in the vehicle frame. If no existing screw is available, you may drill a 3/32" pilot hole for the provided screw. Before drilling, check for miscellaneous items that may be hidden behind or under any surface to avoid damage and personal injury. The area must be free of rust, dirt and paint.
Drill a 3/32" pilot hole if an existing screw with nut is not available in the vehicle frame near the taillight connector. The area should be free of rust, dirt and paint before securing the white ground wire using the ring terminal and provided screw.
Locate a flat spot inside the vehicle near the taillight and adhere the black converter box using the provided double-sided tape. The exact location may vary depending on your vehicle model and available space.
The harness has a yellow wire end for the driver side connection, a green wire end for the passenger side connection, a white ground wire, and a black power wire. The yellow and green wires connect to the vehicle taillight connectors on their respective sides. The white wire provides grounding near the taillight connector. The black power wire routes from the vehicle battery as shown on the included CME-PCL-INS sheet.
The battery connection must be fuse-protected with a 10-amp maximum fuse. Do not exceed this rating, as exceeding the product rating can cause loss of warranty, overheating and potential fire.
After installation is complete, test for proper function by using a test light or connecting a properly wired trailer. All steps must be followed to ensure the wiring harness functions properly. Reconnect the negative battery terminal and reinstall all items removed during installation before testing.
The Curt 56033 includes the custom wiring harness with yellow and green wire ends, a white ground wire with ring terminal, a black power wire, a black converter box, a provided screw for grounding, double-sided tape for mounting the converter box, and a 4-flat dust cover to help prevent corrosion.
For Infiniti G25/G35/G37 sedans, open the tailgate and remove the rear scuff panel, then pull back the felt liner to locate the taillight connectors. For Nissan Rogue, open the trunk, remove the rear scuff panel, storage covers and floor coverings, then remove fasteners securing the rear trim panels on both sides to access the taillight connectors. The connector connection process (Steps 4-5) is the same for both vehicle types.
Do not exceed the product rating (Signal Circuits 3.0 amps per side, Tail/Running Circuits 6.0 amps total) or your tow vehicle's lamp load rating, whichever is lower. Check your vehicle owner's manual or contact the vehicle manufacturer for your specific tow vehicle lamp load rating. Exceeding either rating can cause loss of warranty, overheating and potential fire.
