the pinouts should be the same just the wire colors are different (since thats how it is for the 7A). I have .pdf versions of the ECU wiring diagrams for both engines. I found them on celicatech somewhere, I can't find it anymore but luckily I saved them. the one for the 7A was for 96+ (because I cross-referenced it to a 94-95 and the wire colors were different) so I assume the 5S diagrams I found in the same place are also 96+. if you want to give it a shot I can e-mail it to you, just let me know
