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:• 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 battery, auxiliary circuit, ambient temperature sensor, engine oil level, coolant level, engine speed, start aid solenoid, intake manifold air temperature sensor, engine speed control, exhaust temperature, compressor air inlet pressure, intake manifold pressure, fuel pump, and turbo inlet air temperature.
