Ok, thanks guys, I found the right signal.  The thing I keyed off was Neils
pic with two wires coming from one terminal and only one from the other.  I
stuck my to be mounted tach cluster back there and used a test light from
the neg coil terminal and Voila!...the tach needle moves when I get the
probe onto position #8 of my 14 plug foil....
  So now it's just a matter of stringing that wire up to the front and
swapping all the wire to the appropriate positions in the 'revised'
connection between my 84 and the whatever year foil I have now...according
to the instructions I got off Old Volks write up...It may actually work..
  Scott, your post just came up and that is the way I get the signal...from
the wire that shows no current with key on, motor off.
  Wish me luck when I start doing the "Remove wire 9 and re-insert it into
position 8..take 8 and move it......."  If this all works, I will be really
surprised..but I am recording every step so I can go back to crappy clock if
I don't fry the whole van..
  Thanks all,
 Don Hanson
