Morning all-

How interchangeable are automatics and ECUs? I've a project using a 1MZ, which originally had an A541E FWD box attached to it, and would like to fit an auto from a 1UZ or similar to it. The mechanical side of fitting it is fine, but what about wiring it? Can I just wire the solenoids up to the 1MZ ECU and it'll work like factory, or is there some arcane science behind it all?

Cheers!
