Primary automotive wire is a general purpose insulated wire used to connect electrical components in a vehicle. It has a single conductor and a durable jacket that is oil-, grease-, and flame-resistant, making it ideal for automotive, truck, trailer, marine, and other point-to-point, low-voltage wiring applications.

Automotive wire and battery cable are types of flexible, multistrand wire that transfer current from one electrical component in a motor vehicle to another. They can fit into tight spaces and have a smooth, durable jacket that helps ease installation while providing resistance to oil, grease, acids, and moisture. They are typically used to repair or replace faulty wiring in automotive components, such as sensors, brakes, lights, windows, door locks, and batteries.
