How do I check the Mass Air flow sensor on my V6

I can find all kinds of posts for checking mass air flow on V8 engines which must have a bit different set up because virtually all of the posts tell you to check the voltage at the green wire should be .5 at idle and 5 at WOT etc. etc. etc.

There is no green wire on my V6

I found a reference to checking the voltage at terminal C on the MAF plug in a book I have but it does not tell you which terminal is C again

Please help
