The images can't help. I need to Perform a standalone swap from 3S-FE ECU in ECU into 1G-FE A/T. Meaning that i have 3S-FE Noah engine and I want to connect it to 1G-FE A/T ECU. i need how to perform a swap.

Which car did this combination come in? I can look it up that way.

The problem is that i have an engine of 3s-fe ECU but the transmission is 1g-fe a/t. Ecu. I have 2 ECU. One for engine 3s-fe and on for transmission 1g-fe a/t. I need only transmission wiring diagram for 1g-fe a/t ECU.
