Installation Instructions for 7-Way Pre-Wired Car Connector, 7' Lead (Part 20223)

Tools Required:

• Wire Crimpers
• Wire Cutters
• Test Light or Multimeter
• Pliers
• Drill with 3/32" Drill Bit
• Self-Tapping Screws (provided)
• Cable Ties (optional)
• Electrical Tape (optional)

Overview:

This 7-way pre-wired connector features a 7-foot lead and is designed to extend your vehicle's trailer wiring to hard-to-access areas, such as pickup beds, for towing fifth-wheel or gooseneck trailers. It allows seamless integration with your existing wiring harness for trailer lighting and braking functions.

Step-by-Step Instructions:

1. Mount the 7-Way Connector:

• Select a suitable mounting location, such as near the hitch or in the bed of the truck.
• Use the provided bracket and self-tapping screws to secure the connector.
• Ensure the connector's spring-loaded cover closes tightly to protect it from water and debris.

2. Locate the Wiring Harness:

• Identify the existing vehicle body harness. This is typically located along the driver-side frame rail or under the bed near the taillights.
• Match the wires from the connector harness to the vehicle’s wiring based on function (not color). Use a test light or multimeter to confirm each circuit’s purpose:
  • White Wire: Ground (-)
  • Black Wire: Power (+)
  • Blue Wire: Brake Controller Output
  • Brown Wire: Tail Lights
  • Yellow Wire: Left Turn Signal and Brake
  • Green Wire: Right Turn Signal and Brake
  • Red Wire: Auxiliary or Reverse Lights

3. Connect the Wires:

• Use the provided splice connectors or butt connectors to connect each wire from the 7-way harness to the corresponding wire on the vehicle harness.
• For thicker gauge wires, use the yellow connectors provided in the kit.
• Ensure the white ground wire is connected to a clean, solid grounding point on the vehicle’s frame using a self-tapping screw and ring terminal.

4. Route the Wiring:

• Run the wiring along the frame rail or existing body harness, avoiding hot or moving parts.
• Secure the wiring using cable ties to prevent it from hanging loosely or being damaged.

5. Seal and Protect Connections:

• Once all wires are connected, wrap the splice points with electrical tape to protect against moisture.
• If the wiring passes through metal surfaces, use grommets or silicone to prevent chafing.

6. Test the Functions:

• Verify each function using a test light or by connecting a trailer:
  • Tail Lights (Brown Wire)
  • Left Turn Signal/Brake (Yellow Wire)
  • Right Turn Signal/Brake (Green Wire)
  • Reverse or Auxiliary Power (Red Wire)
  • Trailer Brakes (Blue Wire)
• Use the manual override on your brake controller to ensure the trailer brakes engage.
• Test the running lights and turn signals to confirm proper operation.

7. Finalize Installation:

• Once all functions are confirmed, tidy up the wiring using cable ties.
• Optionally, cover the exposed wiring with wire loom for added protection and a cleaner appearance.

Notes:

• Always match wires by function, not color, as colors may vary between vehicles and trailers.
• Ensure the ground connection is secure and independent of other systems to avoid electrical issues.
• Test all circuits before securing the wiring permanently.

Warning: Improper wiring can cause electrical damage or safety hazards. Ensure all connections are secure and insulated before use.
