  Trouble.  I installed the instrument panel in the car and ran it but the tach is not responding.  verything else works.  I have 2 spare tachs from the PO and would like to check them while running the engine, but before I tear out the instrument panel again, can I connect the a ground to one of the tach retaining screws and 2 - 3 of the other plugs to components under the hood with clips on wires and expect a tach to operate?  There are 3 wires, white w/gray stripe, white and green connected to plugs in the back of the tach.  Where do these connect under the hood?  I tried to trace them on the wiring diagram but haven't had much luck.  The car is equipped with a Pertronics unit in the distributor.
