I understand where your coming from...I too had trouble trying to figure out how to ground the AFM.  If you look at the back of the AFM, you'll see 2 bolt holes (un-used) in the housing (6mm???).  Crimp a "eye-loop" connector on your wire and find a metric bolt that will fit in one of these bolt holes.  At least, that's how I did it.
>Is running wire from the #4 pin(ground ) to the block or alt. bracket acceptable?
Don't know, I was told to ground the AFM housing...

    Installed my tantalum cap. on my AFM and was wondering; I believe it was Karl that said to ground the AFM housing to the block or alternator bracket but I found no easy way to attach a ground to the metal part of the AFM.  Is running wire from the #4 pin(ground ) to the block or alt. bracket acceptable?
     
    Many thanks
