Description
This Seat Belt Pretensioner Wiring Harness is a dedicated replacement for the seat belt pretensioner connection on compatible Citroën and Peugeot vehicles. Supplied under part number 8978FP, the harness restores a secure electrical path for the pretensioner circuit in the vehicle’s Supplemental Restraint System (SRS). It is intended for professional fitters and experienced DIYers who follow SRS safety procedures.
Key Benefits
- Direct-fit replacement for original pretensioner connectors, designed to integrate with existing SRS wiring.
- Helps restore reliable pretensioner signal transmission after connector damage or wire wear.
- Useful spare for workshops working on Citroën Berlingo and Peugeot Partner models where part number 8978FP is referenced.
Function And Fault Symptoms
The wiring harness links the seat belt pretensioner device to the airbag control unit. If the harness is damaged, symptoms can include an illuminated SRS/airbag warning lamp, communication faults recorded in the airbag control module, or a non-functional pretensioner circuit. Common causes of failure are physical damage (accident impact), corrosion, connector breakage, or wire chafing.
Replacement And Installation Notes
Working on SRS components requires caution. General replacement steps:
- Disconnect the negative battery terminal and wait at least 10 minutes to allow residual charge to dissipate.
- Remove interior trim (B-pillar or seat access required) to reach the pretensioner connector and harness routing.
- Disconnect the old harness connector from the pretensioner and airbag control unit connectors; replace with the new 8978FP harness.
- Secure harness routing to prevent chafing and ensure connectors engage firmly; torque any fasteners to manufacturer specification.
- Reconnect the battery, clear SRS codes with a compatible diagnostic tool and verify no warning lamps remain.
Only qualified personnel should perform SRS repairs. If the vehicle has experienced an accident with airbag or pretensioner deployment, replace all deployed components according to vehicle manufacturer guidance.
