Southwire 55667423 18 Awg Automotive Primary Wire 100 Ft Red

Product Description

The SOUTHWIRE 55667423 is an 18 AWG automotive primary wire rated for surface vehicle electrical systems. It ships as a 100-foot spool with red PVC insulation, making it easy to identify in multi-wire harness applications. The wire carries a 60-volt rating and is built with a 16/30 strand configuration, which provides flexibility for routing through tight chassis pathways. Maximum operating temperature is 85 degrees F. This wire is used by automotive technicians, marine electricians, and fleet maintenance professionals who need a reliable, color-coded conductor for low-voltage vehicle circuits.

This wire is suited for residential, commercial, and fleet vehicle electrical work wherever a low-voltage primary circuit is needed. Typical applications include accessory wiring, trailer harnesses, lighting circuits, and general chassis wiring on surface vehicles. The red color coding supports quick circuit identification during installation and troubleshooting. The spool package format allows controlled dispensing in shop and field environments.

Key Features

Compatibility

Designed as an OEM-style primary wire for use in surface vehicle electrical systems per SAE standards. Suitable for automotive, trailer, and light-duty fleet wiring applications requiring 18 AWG low-voltage conductors.

Installation Notes

Installation is performed by automotive or fleet electricians following applicable SAE and vehicle manufacturer wiring guidelines. Disconnect the vehicle battery before beginning any circuit work to prevent shorts or unintended activation of electrical components. Use appropriate wire strippers, crimp terminals, and heat-shrink connectors rated for the circuit ampacity. Avoid routing wire near high-heat sources such as exhaust components without additional protective sleeving.
