Peugeot / Citroën / Renault 2-Pin Fuel Injector Wire Harness Connector – OEM 33404863X / 13106045

A direct-fit OEM-specification 2-pin connector for fuel injector wiring harnesses on Peugeot, Citroën, and Renault vehicles. Matching OEM part numbers 33404863X, 13106045, 13669863, and P00142877, this connector restores a factory-quality electrical connection at the fuel injector — eliminating misfires, rough idle, and fuel delivery faults caused by damaged, corroded, or broken injector connectors.

Available in two connector body types (A and B) and two lead configurations (bare connector or 15cm pre-wired lead), covering the most common Peugeot, Citroën, and Renault injector connector variants across petrol and diesel engine families.

Variant Guide – Which Option Do I Need?

To identify your connector type: compare the housing shape and locking tab position against the product images. Type A and Type B differ in housing geometry — verify before ordering.

Why Replace the Fuel Injector Connector?

The fuel injector connector is exposed to extreme heat cycles, fuel vapour, and engine vibration throughout its service life. Over time, the plastic housing becomes brittle and cracks, the locking tab breaks, or the terminal contacts corrode — causing intermittent or permanent loss of injector signal. Symptoms include:

• Engine misfire on one or more cylinders
• Rough idle or hesitation under load
• Fuel injector fault codes (P0200–P0209 series)
• Poor fuel economy or increased emissions

Replacing the damaged connector with an OEM-specification unit restores reliable injector signal delivery and eliminates these symptoms without replacing the entire wiring harness.

Features & Benefits

• OEM-matched 2-pin layout: Precise pin configuration and housing geometry matches factory Peugeot / Citroën / Renault fuel injector connectors
• Multi-brand compatibility: Covers Peugeot, Citroën, and Renault models sharing the 33404863X / 13106045 connector specification
• Two body types (A & B): Covers the two most common injector connector housing variants across French-market engine families
• 15cm lead option: Pre-wired lead simplifies harness repair — cut, strip, and splice without sourcing separate wire
• Fuel and heat resistant: Housing material engineered to withstand fuel vapour, engine bay heat, and vibration
• Locking retention: OEM-specification locking tab ensures secure, vibration-resistant connection at the injector body
• Direct replacement: No modification to existing wiring required

Installation Guide

1. Identify the damaged injector connector on your vehicle and confirm the connector body type (A or B) using the product images.
2. Disconnect the battery negative terminal before working on fuel injector wiring.
3. Cut the damaged connector from the harness, leaving sufficient wire length for splicing (minimum 3–5cm).
4. Strip the harness wires and the new connector leads (if 15CM variant) to approximately 8–10mm.
5. Join the wires using appropriate crimp connectors or solder-and-heatshrink, maintaining correct polarity.
6. Reconnect the battery and verify injector operation before reassembling engine covers.

Frequently Asked Questions

Q: How do I identify Type A vs Type B?
A: Type A and Type B differ in housing geometry and locking tab position. Compare your existing connector against the product images for each variant. If unsure, order both types — the unused connector can be kept as a spare.

Q: Does this fit diesel injectors as well as petrol?
A: This connector covers both petrol and diesel injector applications on Peugeot, Citroën, and Renault vehicles that use OEM part numbers 33404863X, 13106045, 13669863, or P00142877. Verify against your vehicle’s wiring diagram for diesel-specific applications.

Q: Are terminals/pins included in the connector?
A: The connector is supplied with terminals pre-installed in the housing. The 15CM variant includes pre-wired leads attached to the terminals.

Q: Can I use this on other European brands?
A: This connector is specified for Peugeot, Citroën, and Renault applications. Other European brands may use similar 2-pin injector connectors but with different housing geometries. Verify OEM part numbers before ordering for non-PSA/Renault applications.

Q: What fault codes indicate a failed injector connector?
A: Common fault codes include P0200–P0209 (injector circuit malfunction), P0300–P0309 (cylinder misfire), and manufacturer-specific injector circuit codes. Always diagnose with a scan tool before replacing the connector.
