Automatic transmission models have integrated TCM (Transmission Control Module) pins that communicate with the solenoids. Manual ECUs will lack these circuits. High-Quality Schematics:
: Suzuki changed pinouts between model years and markets (JDM vs. export). Always verify with your specific ECU part number (e.g., 33920-75F* , 33920-77J* ). This document is for reference; miswiring can destroy your ECU. suzuki k6a engine ecu pinout high quality

One day, a customer brought in his Suzuki Jimny, equipped with the renowned K6A engine. The owner wanted to extract more power from his vehicle, but the standard ECU settings were holding him back. Alex, determined to help his customer achieve his goal, decided to dive into the world of engine tuning.
This pinout is compiled from reverse engineering and official Suzuki documentation for pre-2006 Kei vehicles. Always validate on your specific chassis. Incorrect wiring can damage the ECU or engine.
Pins C-19 to C-34 do not exist on a standard 34-pin housing — the 34-pin is arranged 2x17, but I map common expansion:
