Sorry to break your spirit but 7747 does not support IAT (or MAT) functionality. You can switch to a car version, without any harness modifications, of C3 ECM such as 8746 or 16136965 used in later B-bodies which have IAT input at C-12.

i think fast305 has it working with a 7427 which is what you have tbi-max with your 95. the 7427 can run iat. but the tbi trucks with v-8's didnt use it between 87-95 from the factory.
