1. Gathering Materials:
- 4-pin trailer connector
- Electrical wire (usually 4 different colors: white, brown, green, and yellow)
- Wire connectors or crimping tool
- Electrical tape
2. Identifying Brake Light Wires:
a. Locate your vehicle's brake light wires. These wires should typically be red (right), green (left), and black (ground).
3. Wiring the 4-Pin Connector:
a. Take the white wire from the connector and connect it to the left turn signal wire (typically green).
b. Connect the brown wire to the right turn signal wire (typically red).
c. Connect the green wire to the brake light wire (usually a lighter shade of red or may have the letter "B").
d. Finally, connect the yellow wire to the vehicle's ground (typically black).
4. Securing the Connections:
a. Use wire connectors or solder the connections to secure the wires properly.
b. Cover any exposed wires with electrical tape to prevent short circuits.
5. Testing the Connection:
a. Turn on your headlights and brake lights to check the proper functioning of the trailer lights.
Note:
- If your vehicle has separate wires for tail and brake lights, connect the green wire to the tail/running light wire, and then add a separate wire from the brake light wire to the brake light terminal on your 4-pin connector.
- It's important to check your vehicle's specific wiring diagram to ensure accuracy, and consult with an auto expert if you have any electrical concerns or uncertainties.
