Description
Battery negative pole cable for CITROEN and PEUGEOT cars
Part description
This minus engine harness is a used original part designed for Citroën and Peugeot cars. It is an important part of the electrical installation, which ensures a reliable connection of the negative pole of the battery with other parts of the vehicle’s electrical system. The correct function of this cable harness has a major impact on starting, charging and the overall stability of the electrical system.
The part is often searched for by production numbers, so it is particularly suitable for car mechanics and DIYers who are looking for a specific replacement according to the designation. In the case of used electrical parts, it is an advantage to preserve the original design and connectors, which can facilitate the exchange for the original damaged piece.

Installation recommendations
Generally/typically for wiring harness replacements of this type, the exact procedure may vary by specific car model and make. With electrical parts, it is important to proceed carefully in order not to damage the connectors, insulation or connected parts of the electrical installation.
1) Before assembly
- Check whether the new and original design match the length of the cable, the type of terminals, the attachment and the shape of the connectors.
- Inspect the used part for damaged insulation, cracked cable eye, loose crimping, or signs of overheating or oxidation.
- Compare all product numbers on the part with the original piece if legible.
- Disconnect the battery before starting work.
2) Necessary tools and materials
- regular set of hand tools
- socket and socket wrenches
- screwdrivers
- plastic pry bar for removing covers
- cleaning agent for electrical contacts
- cloth or soft brush
3) Step-by-step assembly procedure
- Turn off the ignition and secure the vehicle against movement.
- Disconnect the battery and wait until the electrical system has completely calmed down.
- If necessary, remove covers or parts that prevent access to the volume.
- Carefully document the routing of the original cable, its attachment and connection points.
- Disconnect the original negative harness from all connection points.
- Check the contact surfaces and, if necessary, clean them of oxidation, dirt and grease.
- Place the used part in the same route as the original cable so that it is not in tension or in contact with sharp edges.
- Connect the individual ends of the bundle to their original places and make sure the contacts are seated correctly.
- Secure the cable in all holders and mounts so that it does not come loose or vibrate during operation.
- Reconnect the battery.
- After connection, verify that there are no power outages or abnormal behavior of the electrical system.
-
4) Post-assembly checks and test drive/function verification
- Check that the motor starts without delay and without power fluctuations.
- Verify the correct operation of the vehicle’s basic electrical systems.
- After a short test drive, visually check the cable placement and the strength of the connection again.
- Watch for signs of heating joints or the smell of overheated insulation.
5) The most common assembly mistakes + how to avoid them
- Swapping the cable routing – always note the original placement before disassembly.
- Insufficiently cleaned contacts – dirty or oxidized surfaces can cause contact resistance.
- Assembly of the damaged part – always check the insulation and condition of the terminals before installation.
- Work without disconnecting the battery – increases the risk of short circuits and damage to the electrical installation.
- long-term thermal stress in the engine compartment
- oxidation of contacts and moisture
- mechanical damage to the insulation on surrounding parts
- motor vibration and loose cable attachment
- transient resistance at the connections leading to overheating
- unprofessional previous repair or careless disassembly
