Setup and Installation
This wiring harness is designed for a vehicle-specific fit. While general steps are provided, always refer to the detailed instructions included with your product for precise vehicle-specific guidance. Professional installation is recommended if you are unfamiliar with automotive electrical systems.
General Installation Steps:
- Prepare the Vehicle: Ensure the vehicle is turned off and the battery is disconnected before beginning installation. Access the rear taillight assemblies.
- Locate Connection Points: The harness typically connects behind the vehicle's taillights. You may need to remove taillight assemblies to access the wiring.
- Connect the Harness: Plug the custom connectors from the harness into the vehicle's existing taillight wiring sockets. These are designed for a plug-and-play fit.

- Route Wiring: Carefully route the wiring from the harness module to the desired location for the 4-way flat connector, typically near the trailer hitch. Ensure wiring is secured away from hot or moving parts using the provided zip ties.

- Connect to Battery: Route the power wire (if applicable) to the vehicle's battery, connecting it through the included fuse holder. Always install the fuse as the last step.
- Secure the Module: Mount the main harness module in a dry, secure location within the vehicle's rear compartment, away from moisture and moving parts.
- Reassemble and Test: Reinstall any removed vehicle components. Reconnect the battery and test all lighting functions (turn signals, brake lights, running lights) with a trailer or trailer light tester.
Important Note on Taillight Grommets:
Some vehicle models may have rubber grommets where wires exit the taillight housing into the vehicle's trunk. If the harness wires are routed through these existing grommet holes, ensure the grommet provides a complete seal around the new wiring to prevent water intrusion into the vehicle's interior, especially during car washes or heavy rain. Modifying the grommet to accommodate the new wiring may be necessary, and proper sealing is crucial.

Operating the Wiring Harness
Once installed, the CURT Custom Wiring Harness provides a standard 4-way flat connector for your trailer's electrical system. This connector supplies power for your trailer's running lights, turn signals, and brake lights.
- Connecting a Trailer: Align the 4-way flat connector from your vehicle's harness with the corresponding connector on your trailer and push them firmly together until they are securely seated.
- Disconnecting a Trailer: Grasp both ends of the connector firmly and pull them apart. Avoid pulling on the wires themselves.
- Dust Cover: Always place the included dust cover over the vehicle's 4-way flat connector to protect it from dirt, moisture, and corrosion when not in use.

Maintenance
To ensure the longevity and proper function of your CURT Custom Wiring Harness, follow these maintenance guidelines:
- Keep Connections Clean: Regularly inspect the 4-way flat connector for dirt, debris, or corrosion. Clean with a wire brush or electrical contact cleaner if necessary.
- Apply Dielectric Grease: Apply a small amount of dielectric grease to the electrical terminals of the 4-way flat connector to protect against moisture and corrosion.
- Inspect Wiring: Periodically check all visible wiring for signs of wear, fraying, or damage. Ensure all connections are secure.
- Use Dust Cover: Always use the provided dust cover when the harness is not connected to a trailer.
Troubleshooting
The CURT Custom Wiring Harness features a circuit-protected converter system designed to prevent damage from short circuits or overloads. If you experience issues, consider the following:
Circuit Protected Converter Systems:
This product has been factory tested and built to full specifications. The wiring package includes an electronic module that provides internal circuit protection.
If a short circuit or overload situation occurs in a trailer lighting circuit, the module is designed to shut the circuit down, preventing current flow until the issue is resolved.
If vehicle lamps are working but the trailer lamps are not working, shut power off to the faulted circuit for a few seconds then try the circuit again.
If trailer lamps return to normal function, the issue has been resolved.
If lamps light for a few seconds and then go off:
- Check ground wire on both the harness and trailer.
- Check correct an overload condition (too many bulbs).
If the circuit fails to light:
- Check low vehicle fuse.
- Check cable for broken connections.
- Check for broken bulbs.
- Check ground wire on both the harness and trailer.
- Locate and correct a short.
Note: Using a tester can help confirm system function. If problems persist, see your installer or corrective action. Inspect wiring and connections before towing and frequently while towing.
