MAF wiring diagram

I bought the ULTIMATE PERFORMANCE CHIP for my 04 LEXUS RX 330. This chip is supposed to be connected to the two wires going to the IAT sensor. Unfortunately, the sensor is part of the MAF (Mass Air flow Sensor) assembly and the plug has 5 wires. I have no idea which two wires go to the IAT (Intake Air Temperature Sensor). Could someone help me on this? Thanks, Paul
