I do not have the ECU terminal pinout for the 97-year model specifically, but if my memory serves me correctly then it should be the same as the 96.
I have attached the data pulled from both of the respective manuals that I have for the 2/3RZ engine, which I assume you have. But it's just an assumption based off how common it is to boost.
If these do not help you then maybe
@Enola Gaia can chime in with some more data. I'll keep digging around to see what else I can find.
