17-19 Ford 6.7L High Idle Control

The BD Diesel 17-19 Ford 6.7L High Idle Control is an adjustable idle management solution engineered for PowerStroke diesel operators who demand precision and flexibility. This wiring harness kit addresses a common complaint among Ford Super Duty owners: the need for custom idle speed tuning without expensive ECU reflashing. Whether you're running auxiliary equipment, maintaining warmth in cold climates, or optimizing idle behavior for specific work conditions, this adjustable high idle switch delivers user-controlled RPM management in a 900–3000 RPM operational range.

BD Diesel engineered this control as a fully adjustable wiring harness assembly that integrates seamlessly with the factory electrical architecture of 2017–2019 Ford fullsize trucks equipped with the 6.7L PowerStroke engine. The kit uses a simple, reliable switch-based design to allow drivers to elevate idle RPM on demand—critical for powering hydraulic equipment, generators, or air compressors without relying on engine load alone. The wide tuning range (900–3000 RPM) accommodates diverse applications, from idle stability improvements to active auxiliary power delivery. At just 0.42 lbs, the harness integrates cleanly with minimal footprint and zero modifications to original fuel or ignition systems.

This product is ideal for fleet operators, work-truck owners, and diesel enthusiasts who tow trailers, operate PTO systems, or require consistent idle torque during stationary operation. Professional diesel shops and Ford PowerStroke specialists commonly recommend adjustable idle controls to eliminate stumbling at low RPM and ensure stable idle under parasitic load. Installation involves straightforward harness routing and connection to the factory idle air control circuit—no engine tuning software required. Compatibility is assured for all 2017, 2018, and 2019 Ford fullsize trucks (F-250, F-350, F-450) with the 6.7L turbodiesel engine.
