I've heard 97 is the same as 96 but I haven't confirmed.

and that the 98 ccrm relay has a 2 speed fuel pump set up controlled by the ecm

Hmmm I know you're right but the Ford diagrams show the CCRM pinouts being identical between the two. I'll have to keep digging.

Always heard 98 was programmed a bit more aggressive.

Yeah I've done engine swap and I can't get no fire or nothing I'm regretting doing the engine swap but I have a 99 harness Lane here and I was going to repent it for my PCM but can't find the diagram for my 98 or 99 anywhere
