CURT custom wiring connectors and harnesses are the easiest way to outfit your vehicle with a trailer wiring connection for towing. Each one is custom-fitted to work with a specific make and model. This particular 7-way RV blade socket is designed to be a custom wiring option for certain years of the Buick Enclave, Chevrolet Traverse (except Limited) and GMC Acadia (new body style; see application info to verify fitment).
It provides a universal trailer connection for the tail lights, brake lights, reverse lights, turn signals, electronic trailer brakes and auxiliary power. 7prong taillight wiring can be used as a replacement or new wiring and is typically used for towing fifth wheel and gooseneck trailers.
This 7 way female outlet comes with all necessary hardware to establish a solid connection, as well as a dust cover to keep the connector socket clean when not in use. All CURT custom wiring connectors are made vehicle-specific for the easiest possible installation and the best fit.
Some automotive manufacturers install a special socket on the vehicle to be used for vehicle-to-trailer wiring. Although this factory tow package socket is not equipped on every vehicle, a CURT custom wiring connector (also called a T-connector) utilizes the socket for simple, stress-free installation. Instead of cutting, splicing and soldering into your vehicle's wiring system, the custom wiring connector uses a single OEM compatible plug and instantly provides a standard vehicle-to-trailer hitch wiring connection.
To ensure long-lasting reliability, all CURT custom tconnector wiring is thoroughly tested for optimal functionality.

The CURT Custom Wiring, 7-Way RV Blade, Select Buick Enclave, Chevy Traverse, GMC Acadia 56537 (Part #BKDK56537) Refer to the included instructions for installation details. Basic hand tools are typically all you need.
The Curt 56537 is a custom wiring harness kit designed for SUVs and Vans to provide electrical connections for rear hitch installations. It connects the vehicle's electrical system to a 7-way trailer plug, allowing you to power trailer lights and accessories.
The Curt 56537 is designed for SUVs and Vans. The manual does not specify particular makes or models. Verify fitment with the product listing or contact Curt Manufacturing directly with your vehicle's year, make and model.
Yes. Step 1 requires you to locate the vehicle battery in the engine compartment on the driver side and disconnect the negative battery terminal. Fasten this wire down and away from the battery while completing the installation.
The following tools are required: ratchet, 15mm socket, utility knife, and panel trim removal tool. A 15mm socket is specifically needed to remove the two exhaust hanger mounting bolts if the exhaust hanger blocks access to the harness connector.
Two red 10-amp fuses are required. Step 2 instructs you to verify that these two fuses are installed in the vehicle fuse panel on the driver side under the hood. If they are missing, install the fuses provided in the custom wiring harness kit.
The harness connector is located at the rear of the vehicle on the driver side, above the exhaust hanger. It is concealed behind the panel that covers the hitch and electrical harness. If the exhaust hanger blocks access, you will need to remove its two mounting bolts using a 15mm socket.
Press the red locking tab to the rear of the housing until it clicks. Then press down on the housing lock and pull it away from the mating connector. Remove the dust cover before attempting disconnection.
Not necessarily. The manual provides two procedures: Step 3A (with bumper in place) and Step 3B (with bumper removed). You only need to remove the bumper if the exhaust hanger prevents access to the harness connector from below. If access is possible with the bumper in place, you can proceed without removal.
Route the custom harness from the driver side along the hitch to the center of the vehicle. Mount it near the receiver hitch and connect the 7-way plug onto the custom harness plug. Use cable ties as needed to keep the custom harness mounted in place.
After connecting the harness, reconnect the negative battery terminal (Step 5). Then verify that the harness is functioning by attaching the battery and testing with a test light, 7-way tester, or a functioning trailer. Reinstall all items removed during installation and install the provided dust cover to help prevent corrosion.
Do not exceed the product rating or tow vehicle lamp load rating, whichever is lower. The manual does not specify the product's weight or towing capacity. Contact Curt Manufacturing or check the product documentation for the specific rating.
Do not lay tools across the positive battery terminal (typically noted with red covers or a red '+' symbol). This can cause a ground short, resulting in sparks and/or electrical shocks. When you disconnect the negative battery terminal in Step 1, fasten this wire down and away from the battery.
Periodic inspection of all wires and connections should be performed to ensure there is no visible damage or loose connections. This helps maintain proper function and prevent electrical issues.
The vehicle fuse panel is located on the driver side under the hood. Press the four release tabs to release the cover and lift it straight up. Verify that the two red 10-amp fuses are installed.
If it is not possible to access the harness connector from below the bumper with the exhaust hanger in place, use a 15mm socket to remove the two mounting bolts on the exhaust hanger to access the connector. This allows you to proceed without removing the entire rear bumper.
The Curt 56537 is designed for SUVs and Vans. Verify fitment with the product listing or contact Curt Manufacturing with your vehicle's year, make and model.
You need a ratchet, 15mm socket, utility knife, and panel trim removal tool. The 15mm socket is required to remove exhaust hanger bolts if needed.
Yes, you must disconnect the negative battery terminal before beginning installation. Reconnect it after the harness is connected and before testing.
After reconnecting the battery, test the harness with a test light, 7-way tester, or a functioning trailer to verify proper function.
Do not exceed the product rating or tow vehicle lamp load rating, whichever is lower. The manual does not specify the product's capacity; contact Curt Manufacturing for this information.
Ensure you are pressing the red locking tab to the rear of the housing until it clicks. Then press down on the housing lock and pull it away from the mating connector. If the exhaust hanger is in the way, use a 15mm socket to remove the two exhaust hanger mounting bolts to gain better access.
First, verify that the two red 10-amp fuses are installed in the vehicle fuse panel on the driver side under the hood. Ensure the negative battery terminal is properly reconnected. Test the harness with a test light, 7-way tester, or functioning trailer. Check that all wires and connections are secure and show no visible damage.
