We bought a pre-wired 3uz from S.A. that came with a Hilux electronic accelerator pedal box. I think it's called a flyby wire set-up or drive by wire. [Not sure]. The car has always had issues with throttle response. The engine response doesn't match throttle input. Eventually the ecu went bad and the engine couldn't be revved. At the time we didn't know what to do so we assumed the ecu had blown so we had to buy another ecu.

However, yesterday is when we realized that the pedal box wasn't the oem one. We searched the part number online and discovered it's for a Hilux and not Lexus 430. We've managed to find a Lexus SC430 3uz original accelerator pedal box which matches the ecu that we have, but it has a different socket/plug design. The Hilux pedal box and sc430 box both have 6 pin sockets/connectors.

So please help us figure the pinout for the 3UZFE pedal box and splice it into the wiring that came with the Hilux box.

Any assistance from you will be highly appreciated.Screenshot_20210521-050000_1.jpg

Thanks. So that means the throttle response issues have nothing to do with the pedal box?
