Hey Guys,

Working on swapping the 3uz-fe from my totalled GS430 into my Truck that currently does not have a motor.

Either way I needed the wiring diagrams and ecu pinouts for obvious reasons, so I figured I'd share with you guys.

I'm sure someone will find these useful.














The schematic is not in order but you get the gist

Transmission control wiring is all the same, but the 430 ECU did not have the pins for those controls.

Did you ever found a solution to the OBS2 on the 3UZ Wiring

is there a third page to the actual pin out? Labeling wires using your post and noticed a lot of pins aren’t listed. Thanks
