An Engine Wiring Harness is used to organize individual wires into a single unit to efficiently transmit electrical power and signals using various types of connectors and terminals. The wiring harness protects the cable assembly from abrasion, extreme temperatures, moisture, dust, and other factors.Attributes:• Manufactured to precise specifications and are built for durability, and reliability• Reduce damage to cables from external factors such as dust, debris, and waterApplications:An Engine Wiring Harness is used to securely route the wires and cables and supply power from the electrical system to the engine block heater. This heats the engine coolant before starting, reducing wear and tear on internal components during cold cranks.
