If you want to install an AEM EMS into your NA Supra you will need to install the AEM Map Sensor and a GM IAT (Intake Air Temperature Sensor).
Use the ECU Pinout here:

MAP SENSOR WIRING:
RED wire to pin B-41
BLACK wire to pin B-65
GREEN wire to pin B-62
IAT SENSOR WIRING:
The IAT Sensor has 2 wires, it doesnt matter which way you hook it up as there is no polarity on the Sensor.
It is cleaner for you to wire it in to your MAF PLUG which you are no longer using.
Tap one wire into PIN#3 on your MAF PLUG (PINK/BLUE) (or ECU pin B-45)
Tap the other wire into PIN#4 on your MAF PLUG (BROWN/BLACK) (or ECU pin B-65)
