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 used to connect the battery, alternator, axle oil cooler, engine electronic control module, main chassis, transmission filter bypass, brake oil pressure switch, hydraulic tank oil temperature sensor, turbocharger outlet temperature sensor, throttle position sensor, front and rear axle temperature switch, and fuel level sender.
