Ignition triggers for the Coil-on-Plug (COP) units.
These ECUs typically use four or five plastic connectors. They feature a traditional throttle cable and are the easiest for standalone swaps. 2uzfe ecu pinout
The ECU needs to see a vehicle speed signal. Without it, many 2UZ-FE ECUs will impose a lower RPM limit or harsh shifting. Ignition triggers for the Coil-on-Plug (COP) units
Crankshaft position signal. Without this, the ECU won't fire spark or fuel. G2+: Camshaft position signal. VG: Mass Air Flow (MAF) signal. THW: Engine Coolant Temperature (ECT). VTA1 / VTA2: Throttle Position Sensor (TPS) signals. 3. Control Outputs (The "Muscles") #10, #20, #30, #40...: Fuel injector triggers (8 total). The ECU needs to see a vehicle speed signal
The pinout is often printed in tiny abbreviations directly on the ECU circuit board if you carefully open the metal casing, though this is a last resort.
