I should leave well-enough alone

Okay, although my Elan was running like a scalded cat, I couldn't leave well-enough alone. My original Smiths RVI tach had a fried internal loop (don't ask...) and the needle did not move, but it worked well enough to provide the proper circuit to fire the engine.
While re-wiring my electric window circuits, I thought, "What better time to change-out my old RVI tach with a new RVC tach that I had purchased months ago." I replaced the tach with the new RVC tach using the instructions (see below) that came with it. I ended up with a green wire that was attached to my former RVI tach, now dangling uselessly under my dash... that location having now been usurped by a ground (black) wire.
I turn the key... the ignition light comes on... the engine turns over... and a little curl of white smoke emanates from the crash pad grill! In a panic, I pull the battery disconnect and then inspect the wires behind the dash... no fried wires evident. I re-attach the battery circuit... but the car won't start. Did I fry the tach? HELP!
