obd2 into a obd0 '84 prelude

[Dtfr]

if i have the engine, transmission, sensors, wiring harness, and ecu from a obd2 vehicle what else do i need to put it in a 84 honda prelude obd0 shell

That's pretty much all of it. You'll need to patch then engine harness from the OBD2 Engine in with the cars existing chassis harness, but that's fairly easy. Honda liked keeping things simplified back then, but modular or sectioned harnesses would have been much nicer lol

If you don't wanna do any real wiring, there's a patch over adapter avaiable for nearly every swap you can think of between Honda engines and chassis. Several folks also make custom swap harnesses for decent money. Just ask around or Google.
