Frequently Asked Questions - Trailer Plug Wiring

How to check trailer wiring?

Begin by conducting a thorough visual inspection of the wiring harness, diligently searching for any indications of damage, loose connections, or exposed wires. Following this, establish a connection between your vehicle and the trailer, activating the trailer lights. Ensure all lights, encompassing brake lights, turn signals, and running lights, are operating seamlessly. To assess the functionality of the trailer's brake lights, engage the pedal. If any lights prove faulty, examine the associated wiring connections, fuses, and bulbs for potential issues. If there are any issues, check out our DIY guide on how to replace trailer wiring and lights.

How to waterproof trailer wiring?

Start by utilising waterproof electrical connectors or splices specifically designed for outdoor applications, equipped with seals to thwart water ingress. Enhance protection by wrapping connections with electrical tape or heat shrink tubing, ensuring a thorough coverage of all exposed wires. Securely cover and insulate exposed wires. Apply grease to connectors and terminals for moisture repellence and corrosion inhibition. For added protection, consider employing a wire loom or conduit to shield the wiring from external elements. Optimal protection is essential for enduring and reliable electrical connections.

What size wire do I need for trailer plug wiring?

The wire size required for trailer plug wiring is contingent upon the maximum current capacity demanded by the trailer. As a practical recommendation, for trailers with a maximum current of up to 7.5 amps, a 20-gauge wire is generally adequate. However, it is important to refer to the trailer manufacturer's guidelines or seek professional advice to accurately determine the appropriate wire size for your specific trailer wiring requirements. Make an informed decision to ensure optimal performance and safety in your trailer setup.
