White Wire (Ground)

The white wire is the ground wire, and it connects the trailer’s electrical system to the vehicle’s electrical system. The ground wire is essential to complete the circuit and ensure that the electrical system works correctly. The white wire is usually connected to the vehicle’s chassis.

It is important to ensure that the ground connection is solid and has no rust or corrosion. A loose or poor ground connection can cause issues with the trailer’s electrical system, such as the lights not working correctly.

Brown Wire (Tail Lights)

The brown wire is the tail lights wire, and it connects the trailer’s tail lights to the vehicle’s electrical system. The tail lights wire allows the vehicle’s tail lights to work with the trailer’s tail lights, ensuring that they are synchronized. The brown wire is usually connected to the vehicle’s tail light circuit.

It is important to ensure that the tail lights wire is connected correctly and securely to prevent any damage to the electrical system. A damaged wire can cause issues such as short circuits or blown fuses.

Yellow Wire (Left Turn Signal)

The yellow wire is the left turn signal wire, and it connects the trailer’s left turn signal to the vehicle’s left turn signal. The left turn signal wire allows the vehicle’s left turn signal to work with the trailer’s left turn signal, ensuring that they are synchronized. The yellow wire is usually connected to the vehicle’s left turn signal circuit.

It is important to ensure that the left turn signal wire is connected correctly and securely to prevent any damage to the electrical system. A damaged wire can cause issues such as short circuits or blown fuses.

Green Wire (Right Turn Signal)

The green wire is the right turn signal wire, and it connects the trailer’s right turn signal to the vehicle’s right turn signal. The right turn signal wire allows the vehicle’s right turn signal to work with the trailer’s right turn signal, ensuring that they are synchronized. The green wire is usually connected to the vehicle’s right turn signal circuit.

It is important to ensure that the right turn signal wire is connected correctly and securely to prevent any damage to the electrical system. A damaged wire can cause issues such as short circuits or blown fuses.

Blue Wire (Brake)

The blue wire is the brake wire, and it connects the trailer’s brake system to the vehicle’s brake system. The brake wire allows the vehicle’s brakes to work with the trailer’s brakes, ensuring that they are synchronized. The blue wire is usually connected to the vehicle’s brake light circuit.

It is important to ensure that the brake wire is connected correctly and securely to prevent any damage to the electrical system. A damaged wire can cause issues such as short circuits or blown fuses.

Red Wire (Backup Lights)

The red wire is the backup light wire, and it connects the trailer’s backup lights to the vehicle’s electrical system. The backup light wire allows the vehicle’s backup lights to work with the trailer’s backup lights, ensuring that they are synchronized. The red wire is usually connected to the vehicle’s backup light circuit.

It is important to ensure that the backup light wire is connected correctly and securely to prevent any damage to the electrical system. A damaged wire can cause issues such as short circuits or blown fuses.
