It is essential to identify each wire’s function to ensure that the trailer lights and brakes are working correctly.
Connecting the Trailer Plug to the Trailer
Once you have identified the wires’ function on the trailer plug, the next step is to connect the wires to the corresponding wires on the trailer. Here is a step-by-step guide on how to connect the trailer plug to the trailer:
Step 1: Ground Wire
Connect the white wire to the trailer’s frame with a self-tapping screw. The white wire is the ground wire, and it should be connected to any exposed metal part of the trailer frame.
Step 2: Electric Brake Wire
The blue wire is the electric brake wire. It should be connected to the brake controller’s blue wire that is located under the dash of the vehicle. This wire activates the trailer’s electric brakes when the brake pedal is pressed.
Step 3: Tail/Marker Wire
The green wire is the tail/marker wire. It should be connected to the trailer’s tail/marker lights. The tail/marker lights are usually located at the back and sides of the trailer.
Step 4: Battery Charge Wire
The black wire is the battery charge wire. It should be connected to the trailer’s battery with a 40-amp breaker. This wire charges the trailer’s battery while driving.
Step 5: Stop/Turn, Right Turn/Stop, and Left Turn/Stop Wires
The stop/turn, right turn/stop, and left turn/stop wires should be connected to the trailer’s corresponding lights. The stop/turn wire (red) should be connected to the trailer’s brake lights and turn signal lights. The right turn/stop wire (brown) should be connected to the trailer’s right turn signal and brake light. The left turn/stop wire (yellow) should be connected to the trailer’s left turn signal and brake light.
