Peugeot / Citroën 6-Pin Ignition & Throttle Body Wire Harness Connector – Brown, Red & Green Female OEM

This 6-pin female connector is used in Peugeot and Citroën ignition coil pack and electronic throttle body (ETB) harnesses on PSA Group engines. Available in three housing colors — Brown, Red, and Green — reflecting PSA’s color-coding scheme for different circuit positions in the engine harness. The 6-pin configuration integrates ignition trigger, coil primary power, ground, ion sensing, and throttle position sensor circuits. Available bare or with 15cm pre-wired leads.

PSA Color Coding – Why Brown, Red & Green?

PSA Group uses housing color coding in the engine bay to prevent mis-mating between adjacent connectors of the same pin count. On PSA THP and EP6 engines, the ignition coil pack harness and throttle body harness run in close proximity, and both use 6-pin connectors. The color coding ensures that the ignition connector cannot be accidentally mated to the throttle body connector during engine harness reassembly.

Safety implication: Mis-mating a 6-pin ignition connector to a throttle body position would send ignition trigger signals to the throttle motor, potentially causing uncontrolled throttle opening — a safety-critical error that the color coding system prevents. Always match the replacement connector color to the original OEM housing color for your specific circuit position.

6-Pin Circuit Assignment (THP/EP6 Ignition Coil)

• Pin 1 (IGT): Ignition trigger signal from ECU
• Pin 2 (B+): Coil primary power supply (12V)
• Pin 3 (GND): Coil primary ground
• Pin 4 (IGF): Ignition confirmation feedback to ECU
• Pin 5 (ION): Ion sensing signal (ionization misfire detection)
• Pin 6 (DIAG): Coil diagnostic / temperature monitoring circuit

6-Pin Circuit Assignment (EP6 Electronic Throttle Body)

• Pin 1 (TPS1): Throttle position sensor 1 signal
• Pin 2 (TPS2): Throttle position sensor 2 signal (redundant, for safety)
• Pin 3 (VREF): 5V sensor reference voltage
• Pin 4 (GND): Sensor ground
• Pin 5 (MTR+): Throttle motor positive
• Pin 6 (MTR-): Throttle motor negative

Frequently Asked Questions

Q: How do I know which color connector I need?
A: Match the replacement connector color to the original OEM housing color on your vehicle. Check the PSA wiring diagram for your specific model and engine code to confirm which color corresponds to which circuit position. Never substitute a different color — the color coding is a safety feature.

Q: Does the Mini Cooper S use the same connector?
A: Yes. The Mini Cooper S R56/R60 uses the PSA-sourced EP6/N14/N18 engine, which shares the same ignition coil pack and throttle body connector family as Peugeot and Citroën THP applications.
