Go to the Junk yard and get an old HEI distributor stick in a vice,hook it up to battery and spin it with an electric drill. Don't touch the wire terminals or you will be in for a shocking experience. The HEI has a connection for the Tach.One powwer wire and One for the tach...Oh and of coarse a ground.Good luck . Get someone with a camera for the pic when you do get a shock!!
