Description
Complete engine assembly for CITROEN and PEUGEOT cars with 1.6 HDI engine
It is from a Citroen Xsara Picasso 66kw
Part description
This engine package is intended for Citroën and Peugeot 1.6 HDI cars. It is an important electrical part that connects the individual electrical elements of the engine compartment and ensures the correct transmission of signals and power between components. Parts of this type are often searched for by production numbers, so here you can also find the specific designations 9687146780 and 6569ZW.
The engine wiring harness is a suitable choice when solving problems caused by damaged wire insulation, broken wiring, non-functional connectors or when replacing the original harness with a suitable used part. It is a practical solution for mechanics and home repairers alike if they are looking for an original part to repair the engine wiring.

Installation recommendations
Generally/typically for engine wiring harness replacement, the exact procedure may vary depending on the specific car design and equipment. With electrical parts, it is always important to be careful, to properly run the cabling and to check all connectors thoroughly.
1) Before assembly
- Compare the new and original harness by shape, branch length, type of connectors, and markings on the part.
- Inspect for damage to connectors, latch fuses, wire insulation or wiring protective covers.
- Inspect the bundle for signs of excessive heat, abrasion, or unprofessional previous repairs.
- Disconnect the vehicle battery before starting work.
2) Necessary tools and materials
- Basic set of hand tools
- Screwdrivers and common assembly tools for removing covers and brackets
- Plastic pry bar for gently loosening grips
- Cleaning agent for electrical connectors
- Work lighting
- Straps or fasteners matching the original fit if needed
3) Step-by-step assembly procedure
- Turn off the ignition and disconnect the battery.
- Remove covers and parts that prevent access to the wiring harness.
- Carefully document the original wiring, ideally with photos prior to disassembly.
- Disconnect all connectors of the old harness gradually, without violence and checking the locking elements.
- Release the bundle from all brackets, mounts and protective guides.
- Remove the original bundle and place the replacement next to it for final comparison.
- Place the replacement motor harness in the original route so that it is not twisted, stretched or in contact with sharp edges anywhere.
- Sequentially plug all the connectors into their places and check for a proper click.
- Secure the harness into all original brackets and attachment points.
- Check that the cabling does not run near places with a risk of abrasion, vibration or increased thermal stress.
- Reinstall all covers and removed parts.
- Connect the battery and check the basic functions.
-
4) Post-assembly checks and test drive/function verification
- Check that the motor communicates correctly with the associated electrical components after assembly.
- Verify that no connector is loose and that the harness is not rubbing anywhere.
- After booting, observe for signs of intermittent contact or dropouts.
- After a short test drive, visually check the wiring again.
5) The most common assembly mistakes + how to avoid them
- Exchanging connectors – before disconnecting, mark or take a picture of the individual branches.
- Insufficient bundle fixing – always use all available brackets and guides.
- Damage to the connector latches – disconnect the connectors carefully and without prying with an inappropriate tool.
- Cabling routing through hazardous areas – ensure safe storage away from moving and thermally stressed parts.
- Assembly without comparison with the old part – always compare all branches, lengths and ends before final installation.
Reasons why the part is damaged
- Long-term thermal stress in the engine compartment
- Damage of conductor insulation due to age and vibration
- Abrasion of wiring against surrounding parts or holders
- Intrusion of moisture into the connectors and subsequent corrosion of the contacts
- Unprofessional intervention in the electrical installation or previous cabling repairs
- Mechanical damage during disassembly or servicing of other parts of the car
