Trailer wire, such as those produced by ZW CABLE, is an essential component that connects the electrical system of a trailer to that of a towing vehicle, ensuring the proper operation of both. It’s typically composed of stranded copper wires, each wrapped in a unique color of PVC insulation, with a PVC sheath serving as the outer layer. This design allows it to operate at temperatures as low as -20 degrees Celsius and is characterized by softness, durability, and friction resistance.

Importance of Wiring for Trailers

The importance of wiring for trailers cannot be overstated. It ensures that all electrical components and lights on the vehicle function correctly, providing safety and proper connection. The trailer wire’s gauge, or thickness, and the length of the wiring determine the trailer cable size. This is crucial to ensure proper vehicle operation.

Types of Trailer Wire

Trailer wiring generally uses 16 gauge wire, but for longer trailers, it may be recommended to use a larger gauge wire, such as 14 gauge. Here are the common types of trailer wires:

1. 2 Wire Trailer Wire: This is the simplest form of trailer wire and is typically used for very basic trailers with minimal lighting.
2. 4 Way Trailer Wire: This type of wire is used for trailers with more complex lighting systems. It includes wires for tail lights, turn signals, and ground.
3. 5 Core Trailer Wire: This type of wire is used for trailers with additional lighting or electrical needs beyond the basics.
4. 7 Core Trailer Wire: This is the most comprehensive type of trailer wire. It includes wires for all basic lighting functions, electric brakes, and auxiliary power.

Trailer Wire Colors and Their Functions

For better trailer wiring, each conductor of the trailer cable uses different colors to distinguish its use. Here are the functions of the colors normally used:

• Brown: Used for tail lights, including running lights, number plate lights, and marker lights.
• Yellow: Used for the left turn signal and brake light.
• Green: Used for the right turn signal and brake light.
• White: Used for grounding the trailer to the electrical system of the towing vehicle.
• Blue: Used for the electric trailer braking system.
• Black: Used for the battery of the caravan.
• Red: Used for auxiliary power or additional lighting functions.

How to Wire a Trailer

Here is a step-by-step guide on how to wire a trailer:

1. Prepare the required items: This includes the trailer wire connector, trailer wiring harness, and various hardware.
2. Check the trailer wires: Distinguish the purpose of the various colored wires to facilitate proper connection afterward.
3. Strip the insulation: Do this from both ends of the trailer wires and connect each one safely and securely to the corresponding function.
4. Check the connections: Once the connections are completed, check the functioning of the connected wires.
5. Protect the wire joints: Do this during use to keep them from being damaged.
