An Oil Gauge 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 Oil Gauge Wiring harness is used to securely route the wires and cables and to connect the oil level gauge sensor to the engine control unit or the instrument cluster, allowing for accurate measurement and display of the oil level.
