Hello out there in cyberland. I was just wondering if anyone might be able to help me. I have a 2012 Mazda5, it comes with a 5 wire harness for the MAF,MAP/IAT combo sensor. I am having a hard time finding a wiring diagram for this/these sensors,I need to know what 2 wires run the IAT side of this combo sensor.

 

Have you web searched for a copy of the '12 5 service manual? It will have the wiring schematics.
