Next, identify the wires on your trailer harness and connector. Typically, the colors will match up – for example, white for ground, brown for running lights, yellow for left turn/brake, green for right turn/brake, etc. If you’re unsure, refer to the diagram that came with your connector.
Once you’ve identified the wires, it’s time to start connecting them. Strip the ends of each wire and twist them together according to the diagram. Secure the connections with electrical tape to prevent any loose wires that could cause a short circuit.
After you’ve connected all the wires, do a quick test to make sure everything is working properly. Have someone help you by checking each function (turn signals, brakes, running lights) while you operate the vehicle. If everything checks out, you’re good to go!
