EFI Harness
Cactus Electronics: Professional Automotive EFI Harnesses
As a core part of automotive fuel supply and power control, the Electronic Fuel Injection (EFI) system relies on EFI harnesses—its “neural network”—for accurate operation. With deep expertise in automotive electronic connectivity, Cactus Electronics specializes in designing, developing, producing, and customizing automotive EFI harnesses, covering all wiring assemblies for EFI systems. We deliver stable connections for diverse vehicle EFI setups, enabling precise fuel control, optimized combustion, and maximum engine performance.
Full Range + Professional Design for EFI Needs
Our EFI harnesses outperform standard automotive wiring with professional construction:
- Precise gauge sizing for specific current demands (prevents overload/loss);
- Comprehensive shielding to block electromagnetic interference (protects sensor signals);
- Sealed gold-plated terminal connectors (ensures stability in harsh engine environments: high temps, oil, vibration).
We offer a complete EFI harness lineup:
- Main Harnesses: Core backbone linking ECU to sensors/actuators;
- Injector Harnesses: Ensures accurate fuel injection control;
- Ignition Harnesses: Optimizes spark management for efficiency;
- Advanced Harnesses: Drive-By-Wire (electronic throttle), Transmission Control, and Auxiliary (expanded functions);
- Support Parts: Individual Connectors (custom/repair) and specialized Other Harnesses.
Our low-impedance, anti-interference harnesses sync EFI system data/commands seamlessly, avoiding issues like rough idling, high fuel use, or weak power. We also provide flexible customization—tailoring wire core material (high-purity copper), insulation temp resistance (-40℃ to 125℃), connector pins, and routing to match your EFI specs. Organized, labeled connections simplify installation and troubleshooting.
Certifications + 100% Inspection: Zero Defects Guaranteed
Quality is our priority—electrical issues are a top EFI failure cause, and our professional-grade harnesses mitigate this risk. They hold global certifications:
- ISO 9001: Standardized quality control from sourcing (premium materials, gold-plated terminals) to production (automated equipment) and testing;
- IATF 16949: Meets automotive standards (vibration/EMI/aging resistance);
- UL: Passes safety tests (electrical performance, flame retardancy) to prevent hazards.
Every harness undergoes 100% post-production inspection (continuity, insulation, voltage drop, appearance checks). Only passing units are shipped, ensuring zero defects and reducing your maintenance/after-sales costs.
