Tracing ECU Pinout

When i have plan to swapping my Suzuki Vitara Carburetor Engine with EFI Engine, i need right ECU or Engine Control Unit. It's difficult to find Suzuki Vitara genuine ECU here. So i found closest alternative from Suzuki Baleno mk3, part number 33920-60GB1 . Both have same engine type, and same injector configuration. My engine is old version, it's have 2 injector on at once. Main problem is, i didnt find any information about this ECU pinout. Tracing it one by one is almost impossible. With some guts, i try to open ECU casing, and found pinout label printed on pcb. And after comparing with several Suzuki Baleno Workshop Manual, i found each pinout function. Show in picture #I0 = Injector 3 & 4 ISC = IAC Valve EGR = EGR Valve OXH = Heated Oxygen Sensor FP = Fuel Pump Relay RFC = Radiator Fan Control Relay GC = Blank PSS = Power Steering Pressure Switch STA = Starter Magnetic Switch +B1 = Power Source E1 = Ground Next time i will post my homebrew ECU.
