1999 Silverado Mass Air Flow Sensor

[Uncle Mikey]

Does anyone have or know where I can get a wiring diagram for the Mass Air Flow Sensor? The 99 Silverado has the Intake Air Sensor built into the MAF Sensor. I need to know which two wires control the IAS. Any help would be appreciated!

black wire is ground
tan is signal for the IAT

the IAT intake air temp. located in maf term. B tan 5VOLTS MAX and ground term. A black which goes to the pcm C2 #57 where it is grounded. after engine sits and fully cools down the pcm compares temperature of ECT and IAT if not within 5 degrees will throw code.
