Part description

This used engine harness is intended for Citroën and Peugeot cars and is an important part of the engine electrical installation. It serves to connect individual electrical elements in the engine compartment and ensures the correct transmission of signals and power between components.

The advantage is the specific identification according to the product numbers 9653641280 and 6558TZ, thanks to which the part can be easily located when repairing or replacing a damaged original volume. This type of part is often sought after when solving problems with wiring, broken wires, damaged insulation or malfunctioning connectors.

It is important for mechanics and home repairers that a complete wiring harness can make the repair much easier compared to local intervention in the original wiring, especially if the old harness is damaged in several places or improperly repaired.

Installation recommendations

Generally/typically for engine wiring harness replacement, the exact procedure may vary depending on the specific design of the car and the layout of the engine compartment. Below is a safe and practical general procedure for this type of part.

1) Before assembly

• Check that the product numbers and the overall design of the bundle match the old part.
• Compare the number of connectors, their shape, the length of the bundle branches and the routing of individual branches.
• Inspect the used part for cracked insulation, pulled pins, signs of corrosion, burning or improper repairs.
• Before disassembling the original bundle, it is advisable to take a picture of the wiring and the placement of the connectors.

2) Necessary tools and materials

• Set of common hand tools
• Screwdrivers and a small pry bar for plastic handles
• Pliers for clips and clips
• Cleaning agent for electrical connectors
• Protective gloves and work lighting
• Clamping straps or appropriate fasteners if the original fit needs to be restored

3) Step-by-step assembly procedure

1. Turn off the ignition and disconnect the battery.
2. Get access to the original volume and loosen any covers or clips that prevent disassembly.
3. Sequentially mark the individual connectors if their position may not be clear during reassembly.
4. Disconnect all connectors of the old harness being careful not to damage the latches or pins.
5. Release the harness from all brackets, guides and attachment points.
6. Remove the original bundle and place the new piece next to it for a final comparison of shape and branching.
7. Route the new harness along the same route as the original to avoid straining the cables or contact with hot or moving parts.
8. Connect the individual connectors one by one and always check that they are properly engaged.
9. Fix the harness in all available brackets and clamps so that the wiring does not move freely.
10. Check that the bundle is not pinched, twisted, or unnaturally taut.
11. Connect the battery.
12. After wiring, perform a basic check of the electrical functions related to the motor and observe for signs of poor contact.
• 4) Post-assembly checks and test drive/function verification
  • Check that all connectors are tight and the harness is properly attached.
  • Verify that there is no rubbing against surrounding parts anywhere.
  • After starting, monitor the stability of the operation and verify the functionality of the systems that are connected via the bundle.
  • After a short test drive, visually check the wiring again.

  5) The most common assembly mistakes + how to avoid them

  • Swapping the connectors – marking during disassembly and continuous comparison with the old bundle will help.
  • Insufficient cabling support – always use all available brackets and clamps.
  • Pinching or tensioning of wires – check the entire wiring route before final assembly.
  • Clogged or oxidized contacts – before connecting, it is advisable to visually check the connectors and, if necessary, clean them.
  • Mounting without disconnecting the battery – increases the risk of damage to electrical components.

  Reasons why the part is damaged

  • Aging of the material and embrittlement of the conductor insulation due to time and temperature.
  • Thermal stress in the engine compartment.
  • Vibration which can damage wires or loosen connectors over time.
  • Mechanical abrasion on surrounding parts when the bundle is not properly attached.
  • Moisture and corrosion in connectors that cause transients and dropouts.
  • Incompetent previous repairs, such as wire adjustments or inappropriate interventions in the original wiring.
