Suzuki A/T Shift Lock & Overdrive Switch Wiring Diagram - TCM Circuit

This document is a scanned automotive wiring diagram covering the automatic transmission shift-lock and related control circuits. Power originates at fuse position 13 (15A) in the fuse box, feeding through connector E40 (pin 10) to the lighting switch (OFF/TAIL/HEAD positions), which outputs on an R/Y wire at pin 8. The diagram shows the A/T shift lock solenoid (connector I06), a condenser (I03/I04), an overdrive switch (I05, ON/OFF), a P/N (park/neutral) switch (I02, OFF/ON), and the shift lever illumination light (I07). Circuits route through intermediate connectors E38, G05, G24, and I01, and terminate at the Transmission Control Module (A/T) via connector E43 at pins 17, 19, 10, and 25. Wire color codes shown include W (white), R/Y (red/yellow), B (black), B/G, Bl/G (blue/green), Bl/R (blue/red), O/G (orange/green), O (orange), and R/G (red/green). An output labeled R/G feeds the illumination controller, and two black ground wires terminate at ground points 10 and 9. A reader can trace power flow from the 15A fuse through the lighting and shift-related switches to the transmission control module, and identify connector pin numbers and wire colors for diagnosing shift lock, overdrive switch, P/N switch, or shift lever illumination problems.
