Description
Engine wiring harness Citroën Peugeot 2.0 16V 130 kW RFK from 2004 Peugeot 307 CC. !!!! One two-wire connector is missing, see second photo !!!!
This motor wiring harness is a direct-fit replacement for Citroën/Peugeot 2.0 16V RFK engines rated at 130 kW. Designed for professional workshops and experienced DIY mechanics who often search by product number, this harness carries power and sensor signals for ignition, fuel injectors and various engine-management components. The harness restores correct electrical routing and connector positions to ensure reliable engine operation when the original loom is damaged or degraded.

Function
The wiring harness routes power and low-voltage signals between the engine control unit (ECU), sensors (temperature, MAP/MAP-related sensors, cam/phase sensors), fuel injectors, ignition components and ancillary devices. A correct harness ensures timing, fueling and emissions systems receive accurate data and power, enabling stable idle, full-load performance and fault-free diagnostics.
Installation Recommendations
Replace the harness in a clean, well-lit workshop. Typical installation steps:
- Disconnect the negative battery terminal before starting.
- Document and label connector locations or take reference photos to ensure correct reconnection.
- Remove obstructing components as needed (air intake assembly, battery tray, engine covers) for access to the loom routing.
- Unplug sensor and actuator connectors, then unbolt or unclip the old harness from its mounting points.
- Route the new harness following factory clips and grommets; avoid sharp edges and heat sources.
- Secure connectors and reassemble removed components. Reconnect the battery and clear any stored fault codes after verifying sensor/actuator connections.
Most Common Failure Causes
Wiring harnesses of this type typically fail due to insulation deterioration from heat and oil contamination, connector corrosion, mechanical abrasion where the harness chafes against chassis or engine parts, or physical damage from rodents. Individual connectors or short two-wire leads can break off or suffer internal corrosion, leading to intermittent faults or complete failure of affected circuits. Lifespan depends on vehicle use and environment; age-related wear is the most frequent reason for replacement.
Notes
One two-wire connector is missing on this item (see second photo). Product numbers listed above are commonly used to find the correct replacement; verify these codes against the vehicle’s original harness references before installation.
