This item belongs to the Cables, Harnesses, and Connectors group, meaning it is designed as part of the engine compartment's electrical system. The harness construction includes:

• appropriately selected wire gauge for the sensor's signal load,
• connectors compatible with the oil level sensor and the vehicle's electrical system,
• insulation adapted for operation at elevated temperatures and in the presence of engine oil.

This design promotes a secure electrical connection and minimizes the risk of damage from engine vibrations or contact with other components in the compartment.

Characteristics of a Used Part

The harness is offered as a used part, allowing for an economical repair of the oil level measurement system while maintaining the original manufacturer's specifications. A used component from the cables and connectors group:

• enables the restoration of correct sensor communication with the vehicle's electronics,
• is a good solution in case of mechanical or thermal damage to the factory harness,
• allows for maintaining the installation's consistency with the original mounting standard.

Before installation, it is recommended to inspect the condition of the insulation, connectors, and any signs of tampering to ensure trouble-free operation after replacement.

Installation and Service Recommendations

The oil level sensor harness in the Opel Insignia A 2.0 Cdti should be routed according to factory installation paths, using original clips and ties. During installation, pay attention to:

• ensuring no wire strain in extreme engine and mount positions,
• properly securing connectors to the sensor and the main harness,
• adequate protection of the harness from contact with hot exhaust system components.

After installation, computer diagnostics are recommended to verify the correct oil level readings and the absence of errors in the control unit's memory.
