Its not a direct answer to your question, but check out this thread: Tach Wire (http://www.protege5.com/vbb230/showthread.php?t=24388&highlight=tach+wire) for some help. It solves your problem by taking the signal from one of the two coils and multiplying it to get the actual rpms.

Edit: there are two solutions listed in that thread actually: Single wire for shift light/tach (http://www.mazdamp3.com/vbb225/showthread.php?s=&threadid=31940)
