Only partially true: California trucks with splitshot injectors are pinned out differently than the rest of the OBS trucks with singleshots. I made a couple of Word documents (one pin-for-pin and one with just the differences) for my own curiosity since I have a Cali 97. One exception to the PCMs might be the old 1995 TEE5 programming if you could find one that hasn't been reflashed (Ford sort of de-tuned them a bit due to transmission problems ... a lot of folks were ticked off after they got their trucks back with a non-consent reflash when they took them in for maintenance back in the early days!).
