Setup and Installation
The CURT 58963 wiring harness is designed for a vehicle-specific, plug-and-play installation, eliminating the need for cutting, splicing, or soldering. This harness is specifically designed for select years of the Jeep Cherokee. Always verify fitment for your specific vehicle model year.
Installation Steps:
- Prepare the Vehicle: Ensure the vehicle is parked on a level surface with the engine off and the parking brake engaged. Disconnect the vehicle's battery to prevent electrical shorts during installation.
- Access Tail Light Wiring: Locate and access the existing tail light wiring connectors on your Jeep Cherokee. This typically involves removing tail light assemblies or accessing wiring behind the bumper. Refer to your vehicle's service manual for specific access points.
- Connect the Harness: The CURT harness features original-equipment-compatible connectors. Plug the harness connectors directly into your vehicle's existing tail light wiring system. Ensure a secure and tight connection.

- Route the Wiring: Carefully route the main wiring harness from the rear of the vehicle to the front, where it will connect to the RV. Use the included zip ties to secure the wiring along the vehicle's frame, away from hot or moving parts, to prevent damage.
- Install the 4-Way Flat Connector: Mount the provided connector mounting bracket in a suitable location at the front of the towed vehicle, typically near the hitch or bumper. Secure the 4-way flat connector to this bracket. The 4-way flat extension can be used to provide additional length if needed.

- Connect Ground Wire: Secure the white ground wire with the ring terminal to a clean, unpainted metal surface on the vehicle's frame using a self-tapping screw. A good ground connection is crucial for proper operation.
- Reconnect Battery: Once all connections are made and secured, reconnect the vehicle's battery.
Operation
The CURT 58963 RV Wiring Harness synchronizes the towed vehicle's lighting with your RV's electrical system. When connected, the towed vehicle's tail lights, turn signals, and brake lights will operate in conjunction with the RV's signals, ensuring visibility and compliance with towing regulations.
To operate, simply connect the 4-way flat connector from the towed vehicle to the corresponding 4-way flat socket on your RV. The integrated block diodes protect the towed vehicle's circuits by isolating its sensitive electronics from the RV signals, preventing overheating and short circuiting.

Maintenance
Regular maintenance of your CURT RV wiring harness will ensure its longevity and reliable performance:
- Inspect Connections: Before each towing trip, visually inspect all wiring connections, including the 4-way flat connector, for any signs of corrosion, fraying, or damage.
- Clean Connectors: Keep the 4-way flat connector clean and free of dirt, moisture, and debris. Use a dielectric grease on the pins to prevent corrosion.
- Check Wiring Routing: Periodically check that the wiring remains securely fastened and is not rubbing against sharp edges or hot components. Re-secure with zip ties if necessary.
- Store Properly: When not in use, store the 4-way flat connector in a protected location to prevent exposure to elements.
