Description

Engine harness Citroën Peugeot 2.0 16V 130KW RFK
From 2004 PEUGEOT 307 CC
!!!! One two-wire connector is missing, see second photo !!!!

Part description

Engine wiring harness for Citroën/Peugeot cars with 2.0 16V RFK (130 kW) engine. It is a used part from a Peugeot 307 CC (2004). The harness is used to connect the engine wiring and connectors of individual sensors/actuators in the engine compartment.

Important: according to the documents one two-wire connector is missing (see photo). When choosing, take into account the need to supplement/repair the connector (e.g. re-pinning, supplementing the counterpart, repairing the cabling).

Installation recommendations

Generally/typically for an engine wiring harness, the exact routing and attachment varies by specific car model and make. Consider the procedure below as a practical framework that needs to be adapted to a given installation.

1) Before assembly

• Compare the part codes (9651728880 / 9659205180) and connector type/layout with the old harness.
• Check carefully the condition of the insulation, grommets, attachment points and wiring branches.
• Verify the missing two-wire connector – find out where it should be installed and prepare a repair plan (connector addition, wire repair, heat shrink protection, etc.).
• Check that the pins are not damaged (bent, oxidized) and that the locking pins of the connectors are holding.

2) Necessary tools and materials

• Basic set of hand tools (ratchet/bit, screwdrivers, pliers)
• Tools for working with connectors (small pin extractor/pin extractor), pliers, stripping pliers
• Insulating tape for wiring, textile tape for the engine compartment, tightening tapes
• Material for repairing the missing connector (according to the chosen solution), protective shrink tubes

3) Step-by-step assembly procedure

1. Disconnect the vehicle battery.
2. Ensure access to the wiring (remove the necessary covers/airbox etc. according to the specific car).
3. Document the original condition: take photos of the harness routing, mounting and connector order (helps with reassembly).
4. Mark the connectors (e.g. with tape) and gradually disconnect all connectors of the old harness.
5. Release the bundle from the brackets, slats and mounts; be careful of grommets and places where wiring can rub.
6. Take out the old volume and prepare a new one next to it; compare the branches and lengths so that nothing is in the draw.
7. Install the harness in the car and drive it along the same route as the original (excluding hot spots and moving parts).
8. Snap/fasten the harness into all original brackets and mounts; it must not “hang” freely anywhere.
9. Connect the connectors one by one – always check for proper seating and securing with a fuse.
10. Solve the missing two-wire connector: add/connect the connector so that the connection is mechanically strong, electrically reliable and protected against moisture and vibration.
11. Perform a final visual check that the cabling is not chafed, pinched and protected in hazardous areas.
12. Connect the battery.
• 4) Post-assembly checks and test drive/function verification
  • Check for obvious faults (e.g. malfunctioning sensors/actuators related to disconnected connectors) when the ignition is switched on.
  • Keep the engine running and check that the wiring is not touching moving parts anywhere and that it is not overheating.
  • After a short ride, re-check harness fit and connector repair location.

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

  • Exchanging connectors → mark everything in advance and take photo documentation.
  • Poorly engaged connectors → always pull slightly after connection and check the fuse.
  • Pulling bundle guidance / chafing against the engine → follow the original route and use the correct grips.
  • Incompetent repair of missing connector → repair so that the joint can withstand vibration, heat and moisture; the connector and wires must be secured and insulated.

  Reasons why the part is damaged

  • Aging of the insulation and thermal stress in the engine compartment (brittleness, cracking).
  • Chasing of cabling against sharp edges, poorly routed bundle or missing handles.
  • Intrusion of moisture into connectors (corrosion of pins, transition resistances).
  • Unprofessional interventions in the electrical installation (connections, “home” repairs, pulled out pins).
  • Mechanical damage when disassembling engine components or in an accident.
