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 risk of a short Applications:An Engine Wiring Harness is used to securely route the wires and cables used to connect the battery, auxiliary circuit, pump and parking brake solenoid, inlet air temperature, travel sensor, starter relay coil, glow plug, engine control, oil level, fan control solenoid, and cooling fan speed sensor.
