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.

Battery cable is an insulated, single-conductor wire that connects electrical components in a vehicle to transmit power to the battery. It is comprised of a positive and negative lead. The positive lead connects the battery to the vehicle's ignition, while the negative lead connects the battery to the vehicle chassis, forming an electric ground. Battery cable is flame-retardant and has a robust jacket that is abrasion-, fuel-, oil-, acid-, and salt-resistant. It is commonly used to replace corroded battery cable in automotive, industrial, and marine applications, as well as jumper cables.

Trailer cable is a heavy-duty, flexible wire used to connect the electrical system of a trailer to the main vehicle's battery and electronics systems. It is commonly used in towing applications to provide power to trailer components (such as turn signal indicators, taillights, brake lights, and hazard lights), communicating the driver's actions and promoting safe towing.
