I did it in Word here at work lol.
I dont know how else to do it?! lol
but, WHAT AM I MISSING GOD DAMNIT. and
wtf is
21.) Air Flow Freq. Input/VTM output (Not sure what that is used for)

air flow freq is harman karman airflow signal used by GM vehicle (vette etc), they relay airflow information in frequency instead of rising voltage. so theoretically there's not going to be as low of a limit to how much air it can read.
this is a gm maf:

So i dont need to use it correct?
just cut the maf wire, with in and out like on safc?
