[Precise Matching and Original Replacement] This relay is a direct replacement for original part number 39794-SDA-901, designed for compatibility with multiple Honda and Acura models. Relay failure can cause vehicle starting failure, ECM/PCM power failure (e.g., code P0685), or unstable electrical system operation. This replacement precisely restores its function
[4-Pin SPST Structure and Key Parameters] This relay uses a standard 4-pin single-pole single-throw (SPST) structure and operates at 12V DC. The 4-pin design simplifies connections, typically including two pins for the coil and two pins for the switching contacts (normally open and common), suitable for basic switching control applications
[Solving Starting and Power Failures] This relay effectively solves common problems caused by relay failure, such as engine starting failure, ECM/PCM power failure, and malfunction of related electrical components (e.g., fuel pump, cooling fan). Direct replacement restores stable power supply to the vehicle's electronic control unit and normal starting sequence
【Easy Plug and Play Installation】 The replacement process is simple and requires no tools. Locate the faulty relay in your vehicle's fuse/relay box, simply remove the old one, and insert the new relay. The standard 4-pin layout ensures proper mating, achieving true plug and play
【Value and Convenience Offered by the 3-Piece Pack】 This kit provides three identical high-quality relays, making the cost per relay more advantageous. You can immediately replace the faulty part and keep the spare for future needs or use in other compatible vehicles, ensuring worry-free driving
