Alright so per my remade wiring diagram on page 4 post #55 you will see that the MAP signal Wire is the same Blue w/ White wire at the mass air flow sensor connector, you will also see that two wires to be used with the IAT sensor are also at the mass air flow connector. KEEP IN MIND OBDII CARS HAVE A 12V MASS AIR FLOW POWER REFERENCE .. YOU WILL NEED TO TAP THE TPS (throttle position sensor) FOR THE CORRECT 5V POWER AND GROUND!!!!
