2uzfe Ecu Pinout -

: Heated Oxygen Sensor signals (Sensor 2) for monitoring catalyst efficiency. Power & Grounding: +B / +B2 : Main power supply terminals from the EFI relay.

Verify NE+ and NE- signals. These are sensitive to polarity and shielded to prevent interference.

Since most swap questions revolve around the later, more complex VVTi engine, we’ll focus there. The ECU (Part numbers like 89661-6A380) uses four 22-pin connectors (A, B, C, D). That’s 88 potential circuits.

If you are ditching the factory ECU for a performance build (e.g., Turbo 2UZ), you don't need all the pins. You need a subset. These are sensitive to polarity and shielded to

If you are swapping a 2UZ-FE (Toyota 4.7L V8) into a different chassis (like a 1UZ swap or a restomod) or diagnosing electrical gremlins, the ECU pinout is your bible. The 2UZ-FE was used in the Land Cruiser, Tundra, Sequoia, and 4Runner, and the pinouts differ slightly based on the year and transmission type.

If you have an engine from a 2005-2007 Tundra or 2006-2011 Land Cruiser, stop using the chart above. You need the "Electronic Throttle Control System" pinout.
