An Engine Wiring Harness organizes individual wires into a single unit to efficiently transmit electrical power and signals using various connectors and terminals. The Wiring Harness protects the cable assembly from abrasion, extreme temperatures, moisture, dust, and other factors.Attributes:• Work well in tight spaces where a large number of wires on separate connectors won't fit• Reduces the risk of a short circuit which helps to prevent malfunction or damageApplications:An Engine Wiring Harness is used to securely route the wires and cables to connect the turbocharger exhaust temperature, coolant level sensor, injector solenoid, crankcase pressure sensor, prelube motor, timing calibration, engine oil temperature, and turbocharger inlet pressure.
