CRX-GSR swap: OBD2 throtltle body on OBD1 car?
In the middle of a swap and realize the IACV and throttle bodyare from OBD2. I'm wiring and running stock P72 OBD1 ECU.
I know they got rid of the FITV and redesigned the IACV, but not sure if the OBD1 ECU will look for them.
Thanks.

If it had an FITV then it will CEL without one plugged in. You should be able to grab any OBD1 FITV and just plug it in (they don't need to be functional, just plugged into the harness). IACV shouldn't be a problem either - make sure it's wired correctly (sometimes Honda switches wire positions in the plugs)
