An electrical system comprising various parts used in a car called an Automotive Wiring Harness primarily distributes information and power to a single system. It offers a number of features, including power supply, signal sending and receiving, signal transmission, and information transmission about the operation of the vehicle. Electrical devices, speed sensors, HVAC (heating, ventilation, and air conditioning) systems, and other components are among the parts that are put together.

The starter, battery, and alternator are just a few examples of the parts of a car that need electricity to operate, and the Automotive Wiring Harness connects them all. The electrical connection of automobiles is made simpler by an automotive wiring harness. Due to exposure to extreme heat inside the vehicle engine, the wiring harnesses are built with high-temperature grade materials. An electrical system connection part of an automobile is called an automotive wiring harness.
