Description
Engine harness to the negative pole of the CITROEN PEUGEOT 207 battery
Peugeot negative engine harness 9665205380 5638TN is an original used cable harness designed to connect the negative pole of the battery to the engine and body. A properly functioning engine frame is essential for reliable starting, stable engine operation and trouble-free operation of all Peugeot 207 electrical systems. A worn or corroded negative cable can cause bad starts, voltage fluctuations, control unit errors and various “mysterious” electrical faults, so a quality replacement is key to long-term trouble-free operation.
This harness is suitable for Peugeot 207 cars with both petrol and diesel engines that use this particular type of ground wire. Thanks to the exact shape, original connectors and wire lengths, it fits the original mounting points without the need for modifications, which simplifies and speeds up the repair.
Technical information:
Manufacturer: PSA Peugeot Citroën
Model: Peugeot 207
Part Type: Negative Engine Harness / Battery Negative Harness
Location: connecting the negative battery terminal to the engine block and body
Product codes: 9665205380, 5638TN
Other numbers: may also appear in the documentation under internal PSA numbers depending on the specific version of the equipment and engine
Use in motorizations (typical categories):
– 1.4 16V
– 1.4 VTi
– 1.4 HDi
Advantages of a used original volume:
– original PSA part – correct length, wire cross-section and termination
– high-quality material that resists heating in the engine compartment
– precise attachment to the original holders, without the need for modifications
– reliable current conduction and minimization of transition resistances
Installation recommendations:
– always disconnect the battery before doing any work on the wiring, starting from the negative pole
– carefully clean the contact surfaces on the bodywork and engine (sanding sponge, fine sandpaper), remove corrosion and old deposits of paint or dirt
– check that all connections are tight – a firm and clean connection without play is important for the frame
– use suitable washers and screws with an undamaged thread, or treat the joints with a thin layer of anti-corrosion spray
– make sure the harness is correctly routed in the engine compartment so that it does not come into contact with the exhaust, sharp edges or moving parts
– after assembly, check engine starting and voltage stability of the on-board network (voltage drop at start-up, behavior of lights and on-board systems)
This minus engine harness is a suitable choice for auto mechanics and home repairers who are looking for an efficient and technically correct solution to Peugeot 207 engine frame problems and prefer a used genuine part to a one-size-fits-all replacement.
