Product Description
The BD DIESEL 1036605 High Idle Control is engineered specifically for 2004–2006 Chevrolet and GMC 6.6L Duramax LLY diesel trucks equipped with an automatic transmission and cruise control. This adjustable high idle switch allows you to raise your engine’s idle speed — ideal for faster warm-ups in cold climates, running PTO equipment, or extended idling tasks without a tuning device.
This high idle control system mounts easily under the dash and taps into factory wiring to offer multiple adjustable idle speeds that improve engine warm-up time and support auxiliary uses like PTOs and remote starters. It works exclusively with automatic transmissions and cruise control systems for correct functionality.
