Description
Battery positive wiring harness for CITROËN and PEUGEOT vehicles with 1.6 eHDI 68 kW, 1.4 16V, 1.4 VTi and 1.6 VTi engines. Connecting cable battery-BPGA
This engine wiring harness supplies the positive battery feed to the power distribution (BPGA) and essential engine components. Ideal for professional workshops and competent DIY mechanics, the harness is intended as a direct replacement for vehicles that use the original specification part 6589CC. It restores reliable battery power routing, reduces the risk of voltage drop at the starter and engine electronics, and simplifies repairs with factory-style routing and connector positions.
Key advantages include straightforward fitment, robust conductor sizing to handle starter and charging currents, and factory-compatible terminals that help maintain correct electrical performance. Suitable for routine replacement when diagnostics indicate poor battery feed, visible damage, or intermittent electrical faults related to the battery positive circuit.
Technical Information
- Manufacturer: Stellantis / Citroën / Peugeot
- Model: Citroën C4, Citroën C4 II, Citroën C4 Picasso, Peugeot 307, Peugeot 308
- Product Codes: 6589CC
- Other Numbers: N/A
Installation Recommendation
- Always Disconnect The Battery Before Work: Remove the negative terminal first, then the positive, and follow the vehicle manufacturer’s safety procedure.
- Access And Removal: Locate the positive cable routing from the battery to the BPGA/power distribution. Remove any trim, clips or clamps that retain the harness and carefully unplug electrical connectors.
- Fitment: Route the new harness along the original path, secure all clips and clamps, and ensure connectors fully seat and lock. Keep the harness clear of hot exhaust components and moving parts.
- Final Checks: Reconnect the battery (positive last), check for secure mounting, verify starter engagement and charging system operation, and inspect for absence of warning lights or error codes after installation.
- Recommendation For Professionals: Use basic workshop diagnostic tools to confirm proper voltage at key points and to ensure no parasitic drains or short circuits are present.
Most Common Failure Causes
- Corrosion At Terminals And Connectors: Exposure to moisture and battery acid leads to resistance, overheating and poor contact.
- Heat And Ageing: Prolonged exposure to engine-bay heat can degrade insulation and conductor integrity, causing intermittent faults or short circuits.
- Mechanical Damage And Chafing: Improper routing, loose clips or contact with sharp edges leads to insulation wear and conductor exposure.
- External Damage: Rodent chewing or impact damage from collisions can sever or puncture the harness.
- Symptoms Of Failure: Slow cranking, intermittent starting problems, blown fuses, visible melting or discoloration at terminals, and voltage drop under load.
Part Number: 6589CC. Use the listed models and engine codes to confirm fitment before ordering. This harness is intended for customers who perform repairs themselves as well as professional mechanics looking for a reliable replacement part that restores the battery positive feed to factory routing and function.
