What is an Engine Wiring Harness?

An engine wiring harness is an organized set of wires, cables, connectors and terminals that controls a vehicle’s electrical system. Engine wire harnesses relay electrical power and control information to outlying components such as:

  • Alternators
  • Audio Systems
  • Batteries
  • Blower Motors
  • Computers
  • Fuel Injectors
  • Fuses
  • Windshield Wipers
  • And everything else that is controlled electrically that you can find in a vehicle

An Engine Wiring Harness Acts as a Lifeline to these Devices

In the high performance Original Equipment Manufacturing (OEM) marketplace, there is always a need to make an engine wiring harness more reliable, smaller and with higher electrical capabilities. These environments normally require continued and consistent wire harness performance where inoperativeness cannot be tolerated. These wire harnesses are known as Class 3 and are used in vehicles that operate in harsh and unforgiving environments.

OEMs look for wire and cable harnesses that can withstand vibrations, abrasions, dust and high moisture settings. Constricted wires in a non-flexible bundle help decrease electrical shorts in an engine wire harness. Flame retardant overmolding lowers the risks of electrical fires and keeps moisture out of the wire and cables, preventing corrosion. Adhering the wire harness to the chassis of a vehicle helps prevent vibration and cable abrasions from vehicle movement.
