Description
Battery negative pole cable with control unit for Citroën Peugeot cars
Part description
This battery negative pole cable is part of the electrical installation that ensures reliable grounding and transmission of the necessary signals. Thanks to the integrated control unit, it is important to monitor the conformity according to the product codes – for these parts, the number is often decisive for the correct exchange.
Suitable for use when repairing a damaged cable, grounding faults or when replacing a part with unsatisfactory contact or connectors. The part category corresponds to electrical components / wiring harnesses (motor harnesses).

Installation recommendations
Generally/typically for this type of part it is part of the battery wiring and grounding where safety, clean mating surfaces and proper cable routing are key. The exact steps may vary depending on the specific model and make of the car.
1) Before assembly
- Compare the old and new part according to codes 9664448980 / 9663716180 and possibly other designations.
- Check whether the connectors, insulation, frame eyes or the body of the control unit are damaged (cracks, signs of overheating/oxidation).
- Verify that the shape, length and routing of the cable match (to avoid stress or contact with hot/sharp parts).
2) Necessary tools and materials
- A common set of keys and sockets
- Screwdrivers / pry bar to release plastic clips (according to design)
- Cleaning agent for electrical contacts, cloth
- Protective gloves, possibly insulating tape and tightening tapes for the correct attachment of the cabling
3) Step-by-step assembly procedure
- Turn off the ignition, remove the key and let the car sit (typically to put the electronics to sleep).
- Disconnect the battery (always proceed safely and according to service principles for working on electrical installations).
- Access the cable routing and loosen the clips/grips so that the cable is not pulled by force.
- Disconnect the electrical connectors related to the wiring/control unit (be careful when unlocking the connectors).
- Release and remove the grounding point / cable eye (according to design).
- Disassemble the original cable and compare the orientation and location of the connectors with the replacement piece.
- Clean the contact surfaces of the grounding and check that they are not oxidized or mechanically damaged.
- Install the new cable in the original route, secure it in all the holders so that it does not rub and is not pulled.
- Connect the connectors and make sure the connector locks are properly engaged.
- Connect the grounding and check for a tight and clean fit.
- Reconnect the battery.
-
4) Post-assembly checks and test drive/function verification
- Check that the cable does not interfere with moving parts anywhere and is not in contact with places that could damage the insulation.
- Verify stable start, stable power supply and normal behavior of electrical appliances (no outages).
- After a short test drive, visually check the attachment and any loosening of the attachments.
5) The most common assembly mistakes + how to avoid them
- Uncleaned grounding → oxidation causes transient resistance; always clean the contact surfaces.
- Bad cable routing → penetration of insulation; use the original route and all handles.
- Not clicked connectors → outages and unreliability; always check the connector fuses.
- Manipulation without disconnecting the battery → risk of short circuit/damage to electronics; always disconnect the battery safely.
Reasons why the part is damaged
- Oxidation and corrosion on grounding points and connectors (moisture, salt, age).
- Mechanical damage to the insulation due to rubbing against surrounding parts or inappropriate cable routing.
- Thermal stress in the engine compartment leading to embrittlement of the insulation.
- Unprofessional intervention in the electrical installation (temporary connection, inappropriate attachment, pulling on the cable).
- Vibration and the gradual loosening of the grips, which will subsequently cause damage to the cabling.
