Super resilient cable - for emergency use

 Tractor-trailers come in a variety of sizes, weight classes, and features. Whether you are using a trailer wire spool to haul some personal items, or pulling a livestock trailer, boat trailer, or camper, it is important to have the trailer properly wired.

Using the correct wiring and connectors will help ensure the safe and reliable operation of lights, batteries, brakes, turn signals, and other trailer features such as interior lighting, entertainment systems, and refrigeration. The more complex the wiring of the trailer, the more likely you will need to consider connectors that are designed to handle multiple pins and are resistant to corrosion.

Color code for bonded trailer wire
A good starting point is to know the industry standard color code for tow lines. Green is the right turn signal. Yellow is the left turn signal. White for the ground, brown for the trailer's taillights. These four kinds of wire together constitute the so-called "four-way wire". Four-way wiring is common and is suitable for most light trailers and Marine trailers.

The next level of five-way wiring includes four wires for turn signals, ground and taillights, and a fifth wire (blue) for additional functions-typically used for surge brakes built into trailers or campervans. The fifth wire will usually be plugged into your vehicle's brake lights to ensure that when you activate the vehicle's brakes, the trailer brake lights will also come on. Wires are also plugged into the backlight to trigger disengagement of the trailer brake system.

The six-way trailer wire includes a sixth wire (usually red) for the fuse box or fuse battery lead. The wire will usually be connected to a fuse box separation kit, an internal trailer light, or a battery charger. Can also be used for electric brakes. Six-wire configurations are usually found on horse trailers, such as running fans.

Finally, the seven-way cable (purple) provides another wire for connecting items such as hydraulic couplers.

Typically, trailers or campervans are rolled off the line with built-in wires and corresponding connectors. However, some end users may choose to add battery power or brakes to the trailer after purchase. In any case, trailer wires and connectors wear out over time, so it's important to know the basics of choosing them.

For advanced wiring configurations, and when replacing any corroded or damaged connectors, it is important to consider not only how many wires need to be connected, but also how well the connectors will perform when subjected to shock, vibration, and exposure to components. When selecting a trailer spool, consider that it provides a large number of wire connections for most trailer wiring requirements and is durable. This connector has flat pins and is typically used for trailer connections, as opposed to the connectors with round pins used for RVS.

Other trailer connectors come with additional springs to provide additional stress relief to prevent wire wear and with boots for added seal protection. These features are useful when connectors need to be plugged in and out repeatedly, such as work trailers that are often installed and removed from vehicles.

These are based on the trailer and the conclusion, trailer wire spool is more important than we think, choose the right, good quality trailer line for the trailer, can better improve the performance, for the driver, higher safety.
