Ford / Chevrolet 4-Pin Ignition System Wire Harness Connector – Female OEM

This 4-pin female connector is used in Ford and Chevrolet ignition system harnesses, serving ignition coil, ignition module, or crankshaft/camshaft sensor circuits. The 4-pin configuration integrates ignition trigger, power, ground, and feedback circuits for the ignition control system. Available bare or with 15cm pre-wired leads.

Key Specifications

Why Ignition Connectors Fail

Ignition system connectors on Ford and Chevrolet vehicles are exposed to extreme underhood heat from the ignition coil, vibration, and oil contamination. Terminal corrosion or housing damage causes ignition coil misfires, ignition module communication faults, or P0300-series misfire codes. Replacing the connector restores clean ignition circuit continuity and eliminates misfire-related fault codes.

Variant Guide

• Female – Bare 4-pin housing with terminals
• Female 15CM – Pre-wired with 15cm leads for direct splice-in installation

Installation Steps

1. Disconnect the vehicle battery
2. Allow the ignition coil to cool before working near it
3. Locate the 4-pin ignition connector on the coil or ignition module harness
4. Release the locking tab and unplug the original connector
5. Transfer terminals to the new housing or splice in the pre-wired variant
6. Clear P0300-series misfire codes with Ford IDS/FDRS or GM GDS2
