yes they are the same. i believe the pr4 is 90-93 (b18a1) and the p75 is 94-01 (b18b1). either or will work.

The only year for an OBD1 PR4 is 1993. Otherwise, 94 and up are P75's. But yes, if the plug in, they will work.

what i meant by the same was they are both LS ecu's one is what was found in the integra's that came with the 18ba1 (pr4) and the other b18b1 (p75).
