Description
Connection Cable – Pole Grounding for Citroën C8 and Peugeot 807.
This grounding/earth connection cable (often searched by part numbers) ensures a reliable chassis ground for Stellantis Citroën and Peugeot diesel engines. Designed for use on Citroën C8 and Peugeot 807 models, the cable restores stable electrical reference between the battery/engine and vehicle body, reducing electrical noise and preventing charging and sensor faults. Ideal for professional workshops and DIY mechanics who need a direct replacement based on OEM numbers 1493958080 / 1483693080.
Technical Information
- Manufacturer: Stellantis (Citroën / Peugeot)
- Model: Citroën C8, Peugeot 807
- Product Codes: 1493958080, 1483693080
- Additional Numbers: 5642Y1, 5641EE
Function
The cable provides a low-resistance electrical path between the vehicle body (chassis) and the negative pole/ground point. Proper grounding is critical for correct alternator charging, stable ECU references, sensor readings and to suppress electromagnetic interference. A faulty or high-resistance ground cable can cause charging warnings, erratic sensor values, starting problems or unexpected ECU fault codes.
Installation Recommendations
Replace the ground cable with the engine cold and the ignition off. Recommended steps for safe and reliable installation:
- Disconnect the negative battery terminal before work to avoid short circuits.
- Locate the existing ground strap between the battery/engine block and chassis or body point.
- Remove fastening bolts and any corroded washers. Inspect mating surfaces and clean to bare metal if needed.
- Fit the new cable ensuring correct orientation and full contact of eyelets. Use new hardware if bolts or washers are corroded.
- Tighten fasteners to the manufacturer’s recommended torque and avoid over-bending the cable near terminals.
- After installation, reconnect the battery and verify charging system voltage and absence of warning lights.
Most Common Failure Reasons
Grounding cables typically fail due to:
- Corrosion at terminals and eyelets from moisture, road salt and chemical exposure.
- Frayed or broken conductor strands caused by vibration or mechanical abrasion.
- Heat damage when routed too close to exhaust components or hot engine parts.
- Loose or oxidised contact surfaces leading to increased resistance.
Symptoms Indicating Replacement
Replace the cable if you observe slow cranking, battery/alternator warning lights, intermittent ECU faults, unexplained sensor errors, radio/ignition interference or visible corrosion/damage at connections. There is no fixed replacement interval; service intervals and visual inspections during maintenance are the best way to spot degradation early.
