Most 2UZ-FE ECU configurations use multiple connectors (often five) to manage the engine and transmission. Pin/Terminal Power Supply Main 12V feed from the EFI relay or battery. NE+ / NE- Crankshaft Position
Upgraded to Variable Valve Timing with intelligence, pushing power from ~230 hp to over 270 hp.

Before you touch a single wire, you must identify which generation of 2UZ you own. Toyota changed the game in 2005 (2005.5 for Tundra; 2006 for Land Cruiser). 2uzfe ecu pinout
The following terminals are essential for engine operation and troubleshooting. Voltage checks should be performed with the ignition "ON" or while the engine is idling. Terminal ID Wire Color (Typical) Description & Function Expected Voltage/Signal Main power supply from EFI relay 9 to 14 V (Ignition ON) Gray-Green (GR-G) EFI main relay control signal 9 to 14 V (Ignition ON) Black-White (B-W) Ignition switch input to ECU 9 to 14 V (Ignition ON) Green-Black (G-B) Sensor constant power source 4.5 to 5.5 V (Reference) #10 to #80 Various (e.g., Red) Fuel Injector control pulses (Bank 1 & 2) Pulse waveform (Idling) Yellow-Blue (Y-L) Camshaft Position Sensor signal Pulse waveform (Idling) Crankshaft Position Sensor signal Pulse waveform (Idling) Red / Green Throttle Motor (ETCS-i) drive signals Pulse waveform (Idling) Key System Circuits
Constant 12V power directly from the battery (maintains ECU memory and diagnostic trouble codes).
This paper serves as a foundation for continued research and development, enabling the automotive community to push the boundaries of performance, efficiency, and innovation. I can provide the exact plug location and
Constant 12V from the battery (keeps the ECU memory alive for fault codes).
The is a legendary powerplant, known globally for its presence in the Land Cruiser 100 Series, Tundra, and Sequoia. While the engine is "million-mile" durable, performing an engine swap or troubleshooting a wiring fault requires a deep dive into the Engine Control Unit (ECU) pinout .
Toyota upgraded the platform to an Electronic Throttle Control System-intelligent (ETCS-i) . This iteration introduces an integrated engine immobilizer system, variable valve timing ( VVT-i ), and higher-density 5-plug ECM connectors. 2. Core Pin Groups and Functions Toyota changed the game in 2005 (2005
Crankshaft Position Sensor signals. The ECU cannot fire spark or fuel without this RPM input.
The 2UZ-FE ECU manages several key systems via its connectors, typically arranged in several plugs (e.g., E9, E10, E11, E12). 1. Power and Ground Pins Constant 12V supply for memory. IGSW (IG+): Switched 12V power from the ignition switch.
