If your wiring checks out perfectly but you experience intermittent stalling, random check engine lights, or a total loss of communications, open your metal ECU casing. 1KZ-style ECUs from the 1990s suffer from aging electrolytic capacitors that leak corrosive fluid onto the circuit board traces. Replacing these capacitors can completely revive an erratic ECU without needing to rewire the vehicle.
A traditional throttle cable runs from your pedal to the throttle body. A Throttle Position Sensor (TPS) tells the ECU the cable angle. 1kz ecu pinout

Toyota produced the 1KZ-TE engine from 1993 through the mid-2000s. Over this production run, the ECU configurations changed based on the vehicle model and the presence of an electronic throttle (Drive-by-Wire vs. mechanical cable).

: A well-known problem with 1KZ-TE ECUs is capacitor degradation, causing intermittent starting, stalling, and erratic engine behavior. Visual inspection of the ECU's circuit board for bulging or leaking capacitors is crucial.
The 1KZ-TE is a popular engine for swapping into various vehicles, and understanding the ECU pinout is vital for such a project. Community forums offer a wealth of practical, "real-world" information on this topic.
