- Use a test light or multimeter to confirm the function of each circuit in the harness:
- 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
-
Connect the Wires:
- Match the wires from the USCAR replacement socket harness to the corresponding vehicle harness wires based on function, not color.
- Use the provided splice connectors or butt connectors to secure each connection.
- For thicker gauge wires, use the yellow connectors included 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.
-
Mount the USCAR Socket:
- Attach the USCAR socket to the mounting bracket using the screws and nuts provided.
- Secure the mounting bracket to the hitch or vehicle frame using the provided hardware.
-
Test the USCAR Socket:
- Use a test light or trailer to verify the socket’s functionality before proceeding.
Part 2: Install the 7-Way Connector
-
Plug in the 7-Way Connector:
- Align the connector from the 7-way assembly with the USCAR socket and push it in until it clicks securely.
-
Mount the 7-Way Connector:
- Attach the 7-way connector to the bracket using the provided screws and nuts.
- Ensure the spring-loaded cover is facing upward to protect the connector from water and debris.
-
Secure the Wiring:
- Use cable ties to secure any loose wiring to prevent damage or interference with vehicle components.
-
Test the 7-Way Connector:
- Verify each function of the 7-way connector using a test light or trailer:
- Brown Wire: Tail Lights
- Yellow Wire: Left Turn Signal and Brake
- Green Wire: Right Turn Signal and Brake
- Blue Wire: Trailer Brake Control
- Black Wire: Auxiliary Power
- Red Wire: Reverse Lights
- White Wire: Ground
- Verify each function of the 7-way connector using a test light or trailer:
Notes:
- Always match wires by function, not color, to ensure proper connections.
- Confirm all circuits are functional before securing the wiring permanently.
- Use cable ties to neatly bundle and secure the wiring.
Warning: Incorrect wiring or overloaded circuits can cause electrical damage or fire. Test all connections thoroughly before towing.
