<VV> electrical help

I have a problem.  I'm in the process of installing a Spyder dash into my '60.  I'm doing so for the acquisition of the tach.  After scouring the shop manuals for a couple of hours, I can't seem to find a clear, concise, and understandable wiring diagram of said tach.  The '64 shop manual showed there is one, but the wire goes off into oblivion.  Same for the '65.  None of them show the tach in the dash or any associated wiring. 
   So, could anyone explain how to properly wire in a tach?  Or better yet, furnish a wiring diagram for said installation? 
No reasonable reply refused.  Thanks a million for your help.
