SEAT — Front Seat (Cont'd) — Heating Seat / Thermostat and Wiring Diagram

BF-41wiring diagramUnverified

Switch continuity table is reconstructed from the printed HI/OFF/LO/1-2-3-4 dot matrix; on the switch grid, filled dots indicate continuity. Heated seat circuit gates on ignition-ON/START via a single 10A fuse shared by both seats.
