Southwire 55668023 Automotive Primary Wire 16 Awg 100 Ft Red

Product Description

The SOUTHWIRE 55668023 is a 16 AWG automotive primary wire designed for use in surface vehicle electrical systems. This 100-foot spool is finished in red PVC insulation for easy circuit identification and color-coded wiring layouts. The wire features a 19/29 strand count, giving it the flexibility needed for routing through tight vehicle harness paths. Rated at 60 volts and a maximum temperature of 85 degrees F, it meets SAE standards for automotive electrical applications. Electricians and automotive technicians use this wire for low-voltage DC wiring in cars, trucks, trailers, and other surface vehicles.

This wire is suited for standard 12-volt and 24-volt DC automotive and light-duty commercial vehicle electrical circuits. Typical applications include running power to accessories, trailer wiring, aftermarket audio systems, relay circuits, and general under-hood wiring. The red color coding helps technicians quickly identify positive leads or specific circuit branches during installation and future service work. The spool package format makes it practical for shop use where multiple runs may be needed from a single purchase.

Installation Notes

Installation should be performed by a qualified automotive electrician or experienced technician. Disconnect the vehicle battery before beginning any wiring work to prevent shorts or unintended circuit activation. Route wire away from sharp edges, exhaust components, and moving parts, using grommets and loom where the wire passes through sheet metal. Follow SAE and applicable vehicle manufacturer wiring guidelines for connector selection, fusing, and termination methods.
