Ground Strap
A braided metal cable providing a reliable path for electrical grounding.

Ground straps connect engine and chassis components to the vehicle's negative battery terminal. They ensure proper circuit completion and prevent electrical noise or sensor errors. Corrosion or loose connections cause voltage drops and erratic system behavior. Periodic cleaning and secure mounting maintain electrical integrity. A solid ground system is vital for stable ECU communication and sensor accuracy.
