Default 97 WRX Wagon to 99 Forester ECU Pinout Help

Alright gonna see if i can get some help with this. I made these ECU pinout lists to see what pins I need to move where and some are not used (yellow) and some I don't know what they are (orange) and then I don't know why the sti gets intake air temp but the wrx dosn't (blue).

Should I go through all the trouble of running this with the wrx ecu or should I just get a piggyback and keep the forester ecu? Seems that keeping it would be easier but which way would be better?

If you can chime in with what should go where and what I can leave out I would appreciate it.
