Designed for Fuel Injection Applications
Stable Electrical Connection
Fuel injector circuits require consistently stable low contact resistance to ensure accurate ECU pulse signal transmission. fuel injector connector series adopts an optimized terminal contact structure and has been validated under real engine compartment cycling conditions. It maintains a reliable electrical connection between the ECU, fuel injectors, and engine wiring harness, minimizing signal deviation and helping prevent issues such as unstable idle, misfire fault codes, and power loss. It is suitable for both OEM replacement applications and high-performance modified engine projects.
Waterproof Sealed Protection
Fuel injector connectors are continuously exposed to challenges such as water splash, moisture, dust, and oil vapor intrusion inside the engine compartment. Our sealed fuel injector connectors use dedicated rubber sealing components and a multi-barrier sealing design to prevent water and contaminants from reaching the terminals. This helps reduce oxidation-related issues, including poor contact, signal fluctuations, and fuel injector malfunctions. Suitable for both OEM replacement applications and high-performance engine applications.
Secure Terminal Retention
The connector features a reinforced terminal locking structure with an integrated CPA secondary locking mechanism, securely retaining the terminals inside the connector housing. Validated through automotive vibration cycle testing, it withstands continuous engine vibration, acceleration impacts, and thermal expansion and contraction effects. The design prevents terminal back-out or displacement, ensuring continuous signal transmission and eliminating intermittent circuit failures caused by loose terminals.
Heat Resistance for Engine Environment
The connector housing is made of PA66 GF glass fiber reinforced thermoplastic material, specifically developed for high-temperature engine compartment environments. It maintains stable mechanical and electrical performance across a wide temperature range, ensuring reliable electrical operation. The material helps prevent housing deformation, thermal aging, and sealing failures, providing long service life for OEM replacement applications and high-performance modified engine projects.
Multiple Connector Configurations
Our complete product range includes EV1, EV6, Delphi-style connectors, and direct-fit OEM replacement versions. With various housing configurations, the connectors are compatible with mainstream fuel injector interfaces used in passenger vehicles and high-performance modified engines. The wide selection of options helps reduce component selection efforts for wiring harness manufacturers and aftermarket repair applications.
