P74 is the P06/P28/everything-OBD1-civic-or-integra-except-P75/P72-and-oddball-P07 family of motherboards/code. Motherboards are marked -1720 or -01F0
P75 is the P72 family of hardware/code, marked -1980.
Big whopp-tee-****, the code is all interchangeable, and the ECUs adhere to the same pinouts and sensor network. As long as you don't try to run KS code on an ECU w/o a KS board, or have your VTEC set below your revlimit on an ECU that doesn't have the VTEC circuitry added, it's all the exact same thing.
