CURT 56369 Vehicle-Side Custom 4-Pin Trailer Wiring Harness User Manual

Introduction

The CURT 56369 Vehicle-Side Custom 4-Pin Trailer Wiring Harness is designed to provide a standard, universal trailer wiring connection for select Jeep Compass vehicles. This plug-and-play device integrates with your vehicle's existing electrical system, eliminating the need for cutting, splicing, or soldering during installation. It provides a 4-way flat connector socket for connecting trailer tail lights, brake signal lights, and turn signals, offering a reliable electrical connection for towing applications.

Setup and Installation

This custom wiring harness is designed for easy installation without requiring extensive modifications to your vehicle's wiring. Follow these general steps for installation. Refer to your vehicle's service manual for specific access points to taillight assemblies.

1. Preparation: Ensure your vehicle's engine is off and the parking brake is engaged. Disconnect the negative battery terminal to prevent electrical shorts during installation.
2. Access Vehicle Wiring: Locate and access the vehicle's taillight wiring harness connectors. This typically involves removing taillight assemblies or accessing wiring behind interior trim panels in the trunk or cargo area.
3. Connect T-Connectors: Plug the vehicle-specific T-connectors of the CURT harness directly into the corresponding factory wiring connectors. These are designed for a precise fit, eliminating the need for cutting or splicing.

   

4. Mount Control Module: Secure the control module in a dry, protected location within the vehicle, away from moving parts and excessive heat. Use the provided zip ties or double-sided tape if applicable.
5. Connect Power Wire: Route the power wire from the control module to the vehicle's battery. Install the included fuse holder and fuse as close to the battery as possible. Connect the power wire to the positive battery terminal. Ensure the wire is properly secured and protected from abrasion.
6. Route 4-Way Flat Connector: Route the 4-way flat connector to the exterior of the vehicle, typically near the trailer hitch. Ensure it is accessible for connecting to a trailer.

   

   

7. Test Connection: Reconnect the negative battery terminal. Test the trailer wiring connection by plugging in a trailer or a trailer light tester. Verify that tail lights, brake lights, and turn signals function correctly.

The harness includes a rubber dust cover for the 4-way flat connector to protect it from elements when not in use.

Operation

Once installed, the CURT 56369 wiring harness provides a reliable 4-way flat connection for your trailer. To operate:

• Ensure the 4-way flat connector on your vehicle is clean and free of debris.
• Align the pins of your trailer's 4-way flat connector with the sockets on the vehicle's harness and push firmly to connect.
• Verify that all trailer lights (tail lights, brake lights, turn signals) are functioning correctly before driving.
• When not towing, disconnect the trailer and place the dust cover over the vehicle's 4-way flat connector to protect it.

Maintenance

To ensure the longevity and proper function of your CURT wiring harness:

• Regularly inspect the 4-way flat connector for corrosion, dirt, or damage. Clean with a wire brush or electrical contact cleaner if necessary.
• Keep the dust cover on the connector when not in use to protect it from moisture and debris.
• Periodically check all wiring for signs of wear, fraying, or damage. Ensure all connections remain secure.
• If the fuse blows, replace it with a fuse of the same amperage rating.

Troubleshooting

Note: Using a tester can help confirm system function. For persistent problems, see your installer for corrective action. Avoid overloading the circuit by using proper trailer lighting and frequently verify wiring.
