ABS Wheel sensor signal generator

[Chris Moore]

Hi Shannen,
  I have the GM manuals for the 1995 Seville.  It is very nice.  It 
still does not have the info that I need in it.  The wheel sensor is 
different than most.  It is internal in the wheel bearing and I cannot 
count the teeth.  How else can I get this signal?  Dealers probably 
won't have a clue.  They usually never do.  Especially when I tell them 
what I am doing.  Is there some how I can use the bearing and just spin 
it by hand to get a signal and do some math to make sure I can make a 
generator that is set over the 18 mile/hour mark?
Thanks

Chris Moore
