Wiring Harness
An automotive wiring harness is a bundle of wires, connectors, and terminals that are designed to transmit electrical signals and power between various components in a vehicle. The wiring harness connects various electrical components, including sensors, switches, lights, and other devices, to the vehicle's electrical system, allowing them to function properly. The harness is typically made up of multiple smaller wiring sub-harnesses that are interconnected and routed throughout the vehicle's chassis. The wiring harness is designed to be durable and resistant to environmental factors, such as heat, moisture, and vibration, to ensure reliable operation over the life of the vehicle. The complexity of the wiring harness can vary depending on the make and model of the vehicle and the number and type of electrical components installed. Proper installation and maintenance of the wiring harness is critical to ensure safe and reliable operation of the vehicle's electrical system.

When choosing a vehicle wiring harness, there are two main options: custom-fit and universal. For custom-fit designs, confirm the year, make, model, and engine size of your vehicle. For universal wiring harnesses, create a list of all circuits needed for your project as well as the length of wiring required from headlights to tail lights. From the remaining compatible options, choose the wiring harness that best fits your application and budget needs.
