I am trying to check all the voltages for the MAF. I have a Chiltons manual but for some reason I can't find a diagram that shows which pins are which to correctly measure voltage. Does anyone have this information? Thanks.

 

Pin 2 red wire is 12 volt or battery voltage pin 3 black with white tracer wire ground pin 5 light blue red tracer voltage back to computer this is the one that will vary in voltage with rpm and load change 0 volts key on engine off .7to .9 volts at idle 1 to 1.6 volts at 30mph 1.7 to 2.4 volts at 50mph hope this helps the pin number at the computer is # 88 all this info is acording to ford service manual

 

Thanks, that's exactly what I was looking for.
