The SM 8926 is a premium, ultra-heavy-duty 5-Pin Changeover Relay (SPDT) engineered to match the specialized Toyota HD 2+2 OEM footprint. While it utilizes the high-current "2+2" architecture (large power terminals), it features a 5th center pin for complex changeover logic. Rated at a massive 80A, this relay is designed for the most demanding Toyota and Lexus electrical systems that require switching between two high-draw circuits, such as dual-speed fan controls or advanced battery management systems.
