Southwire 55668323 Automotive Primary Wire 16 Awg 100 Ft

Product Description

The SOUTHWIRE 55668323 is a 16-gauge automotive primary wire designed for low-voltage electrical wiring in surface vehicle electrical systems. Supplied on a 100-foot spool, this wire features a PVC outer insulation rated for up to 85 degrees F and is color-coded yellow for easy circuit identification. The 19/29 strand count construction provides flexibility suited to routed runs in tight spaces. It is rated at 60 volts and carries an outside diameter of 0.105 inches. Licensed automotive electricians and experienced installers use this wire for power distribution, accessory wiring, and circuit extensions in automotive and light-duty vehicle applications.

This wire is intended for use in surface vehicle electrical systems where SAE-compliant primary wire is required. The 100-foot spool length is practical for shop stock, fleet maintenance operations, and mobile equipment wiring jobs. The yellow color coding aids in multi-circuit identification when running alongside other primary wire colors. It suits residential and commercial vehicle service environments alike, including auto shops, fleet service bays, and field repair scenarios where reliable low-voltage wiring is needed.

Installation Notes

Installation should be performed by a qualified automotive electrician or experienced vehicle electrical technician. Disconnect the vehicle battery before beginning any wiring work to eliminate shock and short-circuit risk. Route wire away from sharp edges, exhaust components, and moving parts, using grommets where passing through body panels. Follow SAE and applicable vehicle manufacturer wiring guidelines for connector selection, terminal crimping, and circuit protection.
