I am fitting a AEM ECU to my TT Supra and was just wondering about the air temp sensor wiring, as I am not using the Mass air flow meter and the old temp sensor was incorporated in the unit, I would use the temp wire on the 4 pin MAF plug, looking at the wiring Diags it's pin 45 on the ECU and pin 3 on the MAF plug, Now the other pin on the new Air temp sensor does that go to ground or + 12V?
?? I think it may go to pin 1 on the old MAF sensor plug am I correct
, the reason i say this is that one of the drawings I looked at you could see the resistor inside the MAF block diag connected to pins 1 and 3.
Any advice would be helpfull Thanks .
